一、Spring Security 快速开始

创建SpringBoot项目

$ tree -I test
.
├── pom.xml
└── src
    └── main
        ├── java
        │   └── com
        │       └── example
        │           └── demo
        │               ├── Application.java
        │               └── controller
        │                   └── IndexController.java
        └── resources
            ├── application.yml
            ├── static
            └── templates

引入Spring Security依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>

完整依赖 pom.xml

<?xml version="1.0" encoding="UTF-8"?>

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

配置 application.yml

server:
  port: 8080

启动类 Application.java

package com.example.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class Application {
  public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
  }
}

控制器 IndexController.java

package com.example.demo.controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class IndexController {
    @GetMapping("/")
    public String index(){
        return "Hello";
    }
}

直接访问应用会被重定向到登录页面

http://localhost:8080/
=> 302
http://localhost:8080/login

image.png

现在使用默认的账号密码登录

  • 默认的用户名:user
  • 默认的密码:(控制台打印出的密码)
Using generated security password: cdd28beb-9a64-4130-be58-6bde1684476d

再次访问 http://localhost:8080/

可以看到返回结果

三、Spring Security基础认证与表单认证

认证方式 有无状态 简介 应用场景
基础认证 无状态 不使用cookie 对外API
表单认证 有状态 使用session会话 网站应用
  1. 用户对象 UserDetails
  • 内存存储
  • 数据库存储
  1. 认证对象 Authentication
  • HTTP基础认证
  • HTTP表单认证

1、HTTP基础认证

通过HTTP请求头携带用户名和密码进行登录认证

HTTP请求头格式

# 用户名和密码的Base64编码
Authonrization: Basic Base64-encoded(username:password)

image.png

Spring Boot2.4版本以前

package com.example.demo.config;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.Customizer;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
@Configuration
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        // 所有请求都需要认证,认证方式:httpBasic
        http.authorizeHttpRequests((auth) -> {
            auth.anyRequest().authenticated();
        }).httpBasic(Customizer.withDefaults());
    }
}

Spring Boot2.4版本之后

package com.example.demo.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.Customizer;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.web.SecurityFilterChain;
@Configuration
public class SecurityConfiguration {
    @Bean
    public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
        // 所有请求都需要认证,认证方式:httpBasic
        http.authorizeHttpRequests((auth) -> {
            auth.anyRequest().authenticated();
        }).httpBasic(Customizer.withDefaults());
        return http.build();
    }
}

发送HTTP请求

GET http://localhost:8080/
Authorization: Basic dXNlcjo2ZjRhMGY5ZS1hY2ZkLTRmNTYtYjIzNy01MTZmYmZjMTk3NGM=

可以获得响应数据

Hello

base64解码之后可以得到用户名和密码

atob('dXNlcjo2ZjRhMGY5ZS1hY2ZkLTRmNTYtYjIzNy01MTZmYmZjMTk3NGM=')
'user:6f4a0f9e-acfd-4f56-b237-516fbfc1974c'

2、HTTP表单认证

Spring Security的默认认证方式

image.png

四、Spring Security 用户与认证对象

1、用户对象

接口名 说明
UserDetails 用户对象
GrantedAuthority 用户权限
UserDetailsService 用户对象查询操作
UserDetailsManager 创建用户、修改用户密码

UserDetails 用户对象接口

package org.springframework.security.core.userdetails;
import java.io.Serializable;
import java.util.Collection;
import org.springframework.security.core.GrantedAuthority;
public interface UserDetails extends Serializable {
    // 获取用户权限信息
    Collection<? extends GrantedAuthority> getAuthorities();
    // 获取密码
    java.lang.String getPassword();
    // 获取用户名
    java.lang.String getUsername();
    // 判断账户是否失效
    boolean isAccountNonExpired();
    // 判断账户是否锁定
    boolean isAccountNonLocked();
    // 判断账户凭证信息是否已失效
    boolean isCredentialsNonExpired();
    // 判断账户是否可用
    boolean isEnabled();
}

GrantedAuthority 用户拥有权限接口

package org.springframework.security.core;
import java.io.Serializable;
public interface GrantedAuthority extends Serializable {
    // 获取权限信息
    String getAuthority();
}

UserDetailsService 用户查询操作

package org.springframework.security.core.userdetails;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
public interface UserDetailsService {
    // 根据用户名获取用户信息
    UserDetails loadUserByUsername(String username) throws UsernameNotFoundException;
}

UserDetailsManager 用户CRUD操作

package org.springframework.security.provisioning;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
public interface UserDetailsManager extends UserDetailsService {
    // 创建用户
    void createUser(UserDetails user);
    // 更新用户
    void updateUser(UserDetails user);
    // 删除用户
    void deleteUser(String username);
    // 修改密码
    void changePassword(String oldPassword, String newPassword);
    // 判断用户是否存在
    boolean userExists(String username);
}

2、认证对象

接口名 说明
Authentication 认证请求详细信息
AuthenticationProvider 认证的业务执行者

Authentication 认证请求详细信息

package org.springframework.security.core;
import java.io.Serializable;
import java.security.Principal;
import java.util.Collection;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.core.context.SecurityContextHolder;
public interface Authentication extends Principal, Serializable {
    // 安全主体所具有的的权限
    Collection<? extends GrantedAuthority> getAuthorities();
    // 证明主体有效性的凭证
    Object getCredentials();
    // 认证请求的明细信息
    Object getDetails();
    // 主体的标识信息
    Object getPrincipal();
    // 是否认证通过
    boolean isAuthenticated();
    // 设置认证结果
    void setAuthenticated(boolean isAuthenticated) throws IllegalArgumentException;
}

AuthenticationProvider 认证的业务执行者

package org.springframework.security.authentication;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.AuthenticationException;
public interface AuthenticationProvider {
    // 执行认证,返回认证结果
    Authentication authenticate(Authentication authentication) throws AuthenticationException;
    // 判断是否支持当前的认证对象
    boolean supports(Class<?> authentication);
}

五、基于MySQL自定义认证过程

1、项目结构

$ tree -I target
.
├── pom.xml
└── src
    ├── main
    │   ├── java
    │   │   └── com
    │   │       └── example
    │   │           └── demo
    │   │               ├── Application.java
    │   │               ├── controller
    │   │               │   └── IndexController.java
    │   │               ├── entity
    │   │               │   └── User.java
    │   │               ├── mapper
    │   │               │   └── UserMapper.java
    │   │               ├── security
    │   │               │   ├── SecurityConfiguration.java
    │   │               │   └── UserAuthenticationProvider.java
    │   │               └── service
    │   │                   ├── UserService.java
    │   │                   └── impl
    │   │                       └── UserServiceImpl.java
    │   └── resources
    │       ├── application.yml
    │       ├── sql
    │       │   └── schema.sql
    │       ├── static
    │       └── templates
    └── test
        ├── http
        │   └── IndexController.http
        └── java
            └── com
                └── example
                    └── demo
                        └── ApplicationTests.java

2、用户表

默认表结构的SQL路径

spring-security-core-5.7.6.jar!/org/springframework/security/core/userdetails/jdbc/users.ddl

create table users(
    username varchar_ignorecase(50) not null primary key,
    password varchar_ignorecase(500) not null,
    enabled boolean not null
);
create table authorities (
    username varchar_ignorecase(50) not null,
    authority varchar_ignorecase(50) not null,
    constraint fk_authorities_users foreign key(username) references users(username)
);
create unique index ix_auth_username on authorities (username,authority);

一般情况下,我们使用自己创建的用户表

schema.sql

-- 创建用户表
CREATE TABLE `tb_user` (
  `id` int NOT NULL AUTO_INCREMENT COMMENT '主键id',
  `username` varchar(255) COLLATE utf8mb4_general_ci NOT NULL COMMENT '用户名',
  `password` varchar(255) COLLATE utf8mb4_general_ci NOT NULL COMMENT '密码',
  `nickname` varchar(32) COLLATE utf8mb4_general_ci NOT NULL DEFAULT '昵称',
  `enabled` tinyint NOT NULL DEFAULT '1' COMMENT '账号可用标识',
  PRIMARY KEY (`id`),
  UNIQUE KEY `idx_username` (`username`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci COMMENT='用户表';
-- 添加初始数据
insert into `tb_user` values (1, "zhangsan", "zhangsan", "张三", 1);
insert into `tb_user` values (2, "lisi", "lisi", "李四", 1);
insert into `tb_user` values (3, "wangwu", "wangwu", "王五", 1);

      id-type: AUTO

5、SpringBoot基本框架

启动类 Application.java

package com.example.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

实体类 User.java

package com.example.demo.entity;
import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;

import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import java.util.Arrays;
import java.util.Collection;
@Data
@TableName("tb_user")
public class User implements UserDetails {
    /**
     * 主键id
     */
    @TableId

     * 获取用户权限信息
     *
     * @return
     */
    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        return Arrays.asList(new SimpleGrantedAuthority("ROLE_USER"));
    }
    /**
     * 判断账户是否失效
     *
     * @return
     */
    @Override
    public boolean isAccountNonExpired() {
        return true;
    }
    /**
     * 判断账户是否锁定
     *
     * @return
     */
    @Override
    public boolean isAccountNonLocked() {
        return true;
    }
    /**
     * 判断账户凭证信息是否已失效
     *
     * @return
     */
    @Override
    public boolean isCredentialsNonExpired() {
        return true;
    }
    /**
     * 判断账户是否可用
     *
     * @return
     */
    @Override
    public boolean isEnabled() {
        return this.enabled == 1;
    }
}

UserMapper.java

package com.example.demo.mapper;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.example.demo.entity.User;
import org.apache.ibatis.annotations.Mapper;
@Mapper
public interface UserMapper extends BaseMapper<User> {
}

UserService.java

package com.example.demo.service;
import com.baomidou.mybatisplus.extension.service.IService;
import com.example.demo.entity.User;
public interface UserService extends IService<User> {
}

UserServiceImpl.java

package com.example.demo.service.impl;
import com.baomidou.mybatisplus.core.conditions.query.LambdaQueryWrapper;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.example.demo.entity.User;
import com.example.demo.mapper.UserMapper;
import com.example.demo.service.UserService;
import lombok.extern.slf4j.Slf4j;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;
@Service
@Slf4j
public class UserServiceImpl
        extends ServiceImpl<UserMapper, User>
        implements UserService, UserDetailsService {
    /**
     * 根据用户名获取用户信息
     * @param username
     * @return UserDetails
     * @throws UsernameNotFoundException
     */
    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        LambdaQueryWrapper<User> queryWrapper = new LambdaQueryWrapper<>();
        queryWrapper.eq(User::getUsername, username);
        User user = super.getOne(queryWrapper);
        if(user == null){
            log.error("Access Denied, user not found:" + username);
            throw new UsernameNotFoundException("user not found:" + username);
        }
        return user;
    }
}

IndexController.java

package com.example.demo.controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class IndexController {
    @GetMapping("/hello")
    public String hello(){
        return "Hello";
    }
}

6、自动定义Spring Security

SecurityConfiguration.java

package com.example.demo.security;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.Customizer;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.web.SecurityFilterChain;
@Configuration
public class SecurityConfiguration {
    /**
     * 基于基础认证模式
     * @param http
     * @return
     * @throws Exception
     */
    @Bean
    public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
        // 所有请求都需要认证,认证方式:httpBasic
        http.authorizeHttpRequests((auth) -> {
            auth.anyRequest().authenticated();
        }).httpBasic(Customizer.withDefaults());
        return http.build();
    }
}

UserAuthenticationProvider.java

package com.example.demo.security;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.authentication.AuthenticationProvider;
import org.springframework.security.authentication.BadCredentialsException;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.stereotype.Component;
@Component
@Slf4j
public class UserAuthenticationProvider implements AuthenticationProvider {
    @Autowired
    private UserDetailsService userService;
    /**
     * 自己实现认证过程
     *
     * @param authentication
     * @return
     * @throws AuthenticationException
     */
    @Override
    public Authentication authenticate(Authentication authentication) throws AuthenticationException {
        // 从Authentication 对象中获取用户名和密码
        String username = authentication.getName();
        String password = authentication.getCredentials().toString();
        UserDetails user = userService.loadUserByUsername(username);
        if (password.equals(user.getPassword())) {
            // 密码匹配成功
            log.info("Access Success: " + user);
            return new UsernamePasswordAuthenticationToken(username, password, user.getAuthorities());
        } else {
            // 密码匹配失败
            log.error("Access Denied: The username or password is wrong!");
            throw new BadCredentialsException("The username or password is wrong!");
        }
    }
    @Override
    public boolean supports(Class<?> authentication) {
        return authentication.equals(UsernamePasswordAuthenticationToken.class);
    }
}

7、接口测试

IndexController.http

###
# 不提供认证信息
GET http://localhost:8080/hello
###
# 提供错误的认证信息
GET http://localhost:8080/hello
Authorization: Basic dXNlcjo2YzVlMTUyOS1kMTc2LTRkYjItYmZlMy0zZTIzOTNlMjY2MTk=
###
# 提供正确的认证信息
GET http://localhost:8080/hello
Authorization: Basic emhhbmdzYW46emhhbmdzYW4=
###

六、使用PasswordEncoder加密密码

PasswordEncoder接口

package org.springframework.security.crypto.password;
public interface PasswordEncoder {
    // 对原始密码编码
    String encode(CharSequence rawPassword);
    // 密码比对
    boolean matches(CharSequence rawPassword, String encodedPassword);
    // 判断加密密码是否需要再次加密
    default boolean upgradeEncoding(String encodedPassword) {
        return false;
    }
}

常见的实现类

实现类 说明
NoOpPasswordEncoder 明文存储,仅用于测试
StandardPasswordEncoder SHA-256算法(已过期)
BCryptPasswordEncoder bcrypt算法
Pbkdf2PasswordEncoder Pbkdf2算法

Bcrypt算法简介

例如:

package com.example.demo;
import org.junit.jupiter.api.Test;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
public class BCryptPasswordEncoderTest {
    @Test
    public void encode(){
        BCryptPasswordEncoder bCryptPasswordEncoder = new BCryptPasswordEncoder();
        String encode = bCryptPasswordEncoder.encode("123456");
        System.out.println(encode);
    }
}

输出

$2a$10$lKqmIKbEPNDx/RXssgN6POgb8YssAK7pVtMFDosmC8FxozUgQq58K

解释

$是分隔符
2a表示Bcrypt算法版本
10表示算法强度
中间22位表示盐值
中间面的位数表示加密后的文本
总长度60位

使用Bcrypt算法加密密码后的数据

-- 建表
CREATE TABLE `tb_user` (
  `id` int NOT NULL AUTO_INCREMENT COMMENT '主键id',
  `username` varchar(255) COLLATE utf8mb4_general_ci NOT NULL COMMENT '用户名',
  `password` varchar(255) COLLATE utf8mb4_general_ci NOT NULL COMMENT '密码',
  `nickname` varchar(32) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NOT NULL DEFAULT '' COMMENT '昵称',
  `enabled` tinyint NOT NULL DEFAULT '1' COMMENT '账号可用标识',
  PRIMARY KEY (`id`),
  UNIQUE KEY `idx_username` (`username`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci COMMENT='用户表';
-- 数据
INSERT INTO `tb_user` VALUES (1, 'zhangsan', '$2a$10$/1XHgJYXtF4g/AiR41si8uvVC6Zc.Z9xVmXX4hO2z.b4.DX.H2j5W', '张三', 1);
INSERT INTO `tb_user` VALUES (2, 'lisi', '$2a$10$PEcF03ina7x9mmt2VbB0ueVkLZWQo/yoKOfvfQpoL09/faBlNuuZ.', '李四', 1);
INSERT INTO `tb_user` VALUES (3, 'wangwu', '$2a$10$PMumxkwwrELTbNDXCj0N4.jD/e/Hv.JiiZTFkdFqlDNLU2TahdYNq', '王五', 1);

UserAuthenticationProvider实现类替换如下

package com.example.demo.security;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.security.authentication.AuthenticationProvider;
import org.springframework.security.authentication.BadCredentialsException;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Component;
@Component
@Slf4j
public class UserAuthenticationProvider implements AuthenticationProvider {
    @Autowired
    private UserDetailsService userService;
    // 密码加密
    public PasswordEncoder passwordEncoder(){
        return new BCryptPasswordEncoder();
    }
    /**
     * 自己实现认证过程
     *
     * @param authentication
     * @return
     * @throws AuthenticationException
     */
    @Override
    public Authentication authenticate(Authentication authentication) throws AuthenticationException {
        // 从Authentication 对象中获取用户名和密码
        String username = authentication.getName();
        String password = authentication.getCredentials().toString();
        UserDetails user = userService.loadUserByUsername(username);
        // 替换密码比对方式
        // if (password.equals(user.getPassword())) {
        if (this.passwordEncoder().matches(password, user.getPassword())) {
            // 密码匹配成功
            log.info("Access Success: " + user);
            return new UsernamePasswordAuthenticationToken(username, password, user.getAuthorities());
        } else {
            // 密码匹配失败
            log.error("Access Denied: The username or password is wrong!");
            throw new BadCredentialsException("The username or password is wrong!");
        }
    }
    @Override
    public boolean supports(Class<?> authentication) {
        return authentication.equals(UsernamePasswordAuthenticationToken.class);
    }
}

七、Session会话控制

修改配置类SecurityConfiguration

package com.example.demo.security;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.Customizer;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.http.SessionCreationPolicy;
import org.springframework.security.web.SecurityFilterChain;
@Configuration
public class SecurityConfiguration {
    /**
     * 基于基础认证模式
     * @param http
     * @return
     * @throws Exception
     */
    @Bean
    public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
        // 禁用session会话
        http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
        // 所有请求都需要认证,认证方式:httpBasic
        http.authorizeHttpRequests((auth) -> {
            auth.anyRequest().authenticated();
        }).httpBasic(Customizer.withDefaults());
        return http.build();
    }
}

八、基于表单模式实现自定义认证

SecurityFormConfiguration 配置类

package com.example.demo.security;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.http.SessionCreationPolicy;
import org.springframework.security.web.SecurityFilterChain;
@Configuration
public class SecurityFormConfiguration {
    /**
     * 基于表单认证模式
     * @param http
     * @return
     * @throws Exception
     */
    @Bean
    public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
        // 启用session会话
        http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.IF_REQUIRED);
        // 认证方式:Form
        http.authorizeRequests()
                // 所有请求都需要认证
                .anyRequest().authenticated()
                .and()
                // 启动表单认证模式
                .formLogin()
                // 登录页面
                .loginPage("/login.html")
                // 请求提交地址
                .loginProcessingUrl("/login")
                // 放行上面的两个地址
                .permitAll()
                // 设置提交的参数名
                .usernameParameter("username")
                .passwordParameter("password")
                .and()
                // 开始设置注销功能
                .logout()
                // 注销的url
                .logoutUrl("/logout")
                // session直接过期
                .invalidateHttpSession(true)
                // 清除认证信息
                .clearAuthentication(true)
                // 注销成功后跳转地址
                .logoutSuccessUrl("/login.html")
                .and()
                // 禁用csrf安全防护
                .csrf().disable();
        return http.build();
    }
}

登录页面 static/login.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Login</title>
</head>
<body>
<h2>Login</h2>
<form action="/login" method="post">
    <div><label>username:<input type="text" name="username"></label></div>
    <div><label>password:<input type="password" name="password"></label></div>
    <div><input type="submit"></div>
</form>
</body>
</html>
