简介： 该文档介绍了SpringSecurity6中默认用户的生成流程。在`SecurityAutoConfiguration`源码中，通过`SecurityProperties`配置类，系统默认创建了一个名为"user"的用户，其密码是一个随机生成的UUID。这个用户是在没有在`application.properties`中设置相关配置时自动创建的。

SpringSecurity6从入门到实战之默认用户的生成流程

这次还是如标题所示,上一章我们的登录页面已经知道是如何生成了.那么,我们通过表单登录的user用户以及密码SpringSecurity是如何进行生成的呢?

默认用户生成

让我们把登录流程重新拉回到读取/META-INF/spring/ .imports文件

我们进入SecurityAutoConfiguration源码中查看上面加载的注解

package org.springframework.boot.autoconfigure.security.servlet;
@AutoConfiguration
@ConditionalOnClass({DefaultAuthenticationEventPublisher.class})
//加载配置类让SecurityProperties配置类生效
@EnableConfigurationProperties({SecurityProperties.class})
@Import({SpringBootWebSecurityConfiguration.class, SecurityDataConfiguration.class})
public class SecurityAutoConfiguration {
    public SecurityAutoConfiguration() {
    }
    @Bean
    @ConditionalOnMissingBean({AuthenticationEventPublisher.class})
    public DefaultAuthenticationEventPublisher authenticationEventPublisher(ApplicationEventPublisher publisher) {
        return new DefaultAuthenticationEventPublisher(publisher);
    }
}

一般以Properties命名结尾的都是对应的配置类,分别对应application.properties的内容,但是现在我们在application.properties中并没有配置任何内容.

SecurityProperties

public class SecurityProperties {
    public static final int BASIC_AUTH_ORDER = 2147483642;
    public static final int IGNORED_ORDER = Integer.MIN_VALUE;
    public static final int DEFAULT_FILTER_ORDER = -100;
    private final Filter filter = new Filter();
    //这里就是默认创建的一个用户
    private final User user = new User();
    public SecurityProperties() {
    }
    public User getUser() {
        return this.user;
    }
    public Filter getFilter() {
        return this.filter;
    }
    public static class Filter {
        private int order = -100;
        private Set<DispatcherType> dispatcherTypes = EnumSet.allOf(DispatcherType.class);
        public Filter() {
        }
        public int getOrder() {
            return this.order;
        }
        public void setOrder(int order) {
            this.order = order;
        }
        public Set<DispatcherType> getDispatcherTypes() {
            return this.dispatcherTypes;
        }
        public void setDispatcherTypes(Set<DispatcherType> dispatcherTypes) {
            this.dispatcherTypes = dispatcherTypes;
        }
    }
    public static class User {
        private String name = "user";
        private String password = UUID.randomUUID().toString();
        private List<String> roles = new ArrayList();
        private boolean passwordGenerated = true;
        public User() {
        }
        public String getName() {
            return this.name;
        }
        public void setName(String name) {
            this.name = name;
        }
        public String getPassword() {
            return this.password;
        }
        public void setPassword(String password) {
            if (StringUtils.hasLength(password)) {
                this.passwordGenerated = false;
                this.password = password;
            }
        }
        public List<String> getRoles() {
            return this.roles;
        }
        public void setRoles(List<String> roles) {
            this.roles = new ArrayList(roles);
        }
        public boolean isPasswordGenerated() {
            return this.passwordGenerated;
        }
    }
}
