在spring security的内置login处理是无法满足要求的，需要自己进行各种定制。这里介绍login中实现验证码的实现。

实现方法

可以有三种方法可以实现验证码的功能

第一种

自定义一个filter，放在SpringSecurity过滤器之前，在用户登录的时候会先经过这个filter，然后在这个filter中实现对验证码进行验证的功能，这种方法不推荐，因为它已经脱离了SpringSecurity

第二种

自定义一个filter让它继承自UsernamePasswordAuthenticationFilter，然后重写attemptAuthentication方法在这个方法中实现验证码的功能，如果验证码错误就抛出一个继承自AuthenticationException的验证吗错误的异常比如（CaptchaException），然后这个异常就会被SpringSecurity捕获到并将异常信息返回到前台，这种实现起来比较简单。
譬如：LoginAuthenticationFilter.java

import com.google.code.kaptcha.Constants;
import com.tangcheng.app.domain.exception.CaptchaException;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;
import org.springframework.security.web.util.matcher.AntPathRequestMatcher;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class LoginAuthenticationFilter extends UsernamePasswordAuthenticationFilter {

    public LoginAuthenticationFilter() {
        AntPathRequestMatcher requestMatcher = new AntPathRequestMatcher("/login", "POST");
        this.setRequiresAuthenticationRequestMatcher(requestMatcher);
        this.setAuthenticationManager(getAuthenticationManager());
//        this.setAuthenticationFailureHandler(new LoginAuthenticationFailureHandler());
    }

    @Override
    public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException {
        String verification = request.getParameter("code");
        String captcha = (String) request.getSession().getAttribute(Constants.KAPTCHA_SESSION_KEY);

        if (!captcha.contentEquals(verification)) {
            throw new CaptchaException("captcha code not matched!");
        }
        return super.attemptAuthentication(request, response);
    }
}

java config:

public class SecurityConfig extends WebSecurityConfigurerAdapter {


@Override
protected void configure(HttpSecurity http) throws Exception {
    LoginAuthenticationFilter loginAuthenticationFilter = new LoginAuthenticationFilter();
    loginAuthenticationFilter.setAuthenticationManager(authenticationManager());
    loginAuthenticationFilter.setAuthenticationFailureHandler(authenticationFailureHandler());
....

http.authorizeRequests()

...

.addFilterBefore(loginAuthenticationFilter, UsernamePasswordAuthenticationFilter.class)
...

自定义的跳转url，方便前端进行友好提示

    @Bean
    public AuthenticationFailureHandler authenticationFailureHandler() {
        ExceptionMappingAuthenticationFailureHandler failureHandler = new ExceptionMappingAuthenticationFailureHandler();
        Map<String, String> failureUrlMap = new HashMap<>();
        failureUrlMap.put(BadCredentialsException.class.getName(), LoginAuthenticationFailureHandler.PASS_ERROR_URL);
        failureUrlMap.put(CaptchaException.class.getName(), LoginAuthenticationFailureHandler.CODE_ERROR_URL);
        failureUrlMap.put(AccountExpiredException.class.getName(), LoginAuthenticationFailureHandler.EXPIRED_URL);
        failureUrlMap.put(LockedException.class.getName(), LoginAuthenticationFailureHandler.LOCKED_URL);
        failureUrlMap.put(DisabledException.class.getName(), LoginAuthenticationFailureHandler.DISABLED_URL);
        failureHandler.setExceptionMappings(failureUrlMap);
        return failureHandler;
    }

或xml配置：

<bean id="loginFilter" class="com.zrhis.system.security.DefaultUsernamePasswordAuthenticationFilter">  
    <property name="authenticationManager"  ref="authenticationManager"></property>  
    <property name="authenticationSuccessHandler">  
        <bean class="org.springframework.security.web.authentication.SavedRequestAwareAuthenticationSuccessHandler">  
            <property name="defaultTargetUrl" value="/index.jsp"></property>  
        </bean>  
    </property>  
    <property name="authenticationFailureHandler">  
        <bean class="org.springframework.security.web.authentication.SimpleUrlAuthenticationFailureHandler">  
            <property name="defaultFailureUrl" value="/login.jsp"></property>  
        </bean>  
    </property>  
</bean>

最后在http中加入custom-filter配置，将这个filter放在SpringSecurity的FORM_LOGIN_FILTER之前.

<custom-filter ref="loginFilter" before="FORM_LOGIN_FILTER"/>

第三种

直接替换掉SpringSecurity的UsernamePasswordAuthenticationFilter，这种比较复杂，但是更为合理，也是我现在正在用的。
如果用这种方法那么http 中的auto-config就必须去掉，而form-login配置也必须去掉，因为这个不需要了，里面的属性都需要我们自行注入。

首先需要创建并配置一个login.jsp作为登录页面EntryPoint

<bean id="authenticationEntryPoint" class="org.springframework.security.web.authentication.LoginUrlAuthenticationEntryPoint">  
    <property name="loginFormUrl" value="/login.jsp" />  
</bean>

然后在http中配置下

<sec:http access-decision-manager-ref="accessDecisionManager"  entry-point-ref="authenticationEntryPoint">

然后我们来写CaptchaAuthenticationFilter，同样需要继承自UsernamePasswordAuthenticationFilter

public class CaptchaAuthenticationFilter extends UsernamePasswordAuthenticationFilter{  

    public static final String SPRING_SECURITY_FORM_CAPTCHA_KEY = "j_captcha";  
    public static final String SESSION_GENERATED_CAPTCHA_KEY = Constant.SESSION_GENERATED_CAPTCHA_KEY;  

    private String captchaParameter = SPRING_SECURITY_FORM_CAPTCHA_KEY;  

    public Authentication attemptAuthentication(HttpServletRequest request,  
            HttpServletResponse response) throws AuthenticationException {  

        String genCode = this.obtainGeneratedCaptcha(request);  
        String inputCode = this.obtainCaptcha(request);  
        if(genCode == null)  
            throw new CaptchaException(this.messages.getMessage("LoginAuthentication.captchaInvalid"));  
        if(!genCode.equalsIgnoreCase(inputCode)){  
            throw new CaptchaException(this.messages.getMessage("LoginAuthentication.captchaNotEquals"));  
        }  

        return super.attemptAuthentication(request, response);  
    }  

    protected String obtainCaptcha(HttpServletRequest request){  
        return request.getParameter(this.captchaParameter);  
    }  

    protected String obtainGeneratedCaptcha (HttpServletRequest request){  
        return (String)request.getSession().getAttribute(SESSION_GENERATED_CAPTCHA_KEY);  
    }  

}

Java Config:

public class SecurityConfig extends WebSecurityConfigurerAdapter {


@Override
protected void configure(HttpSecurity http) throws Exception {
    CaptchaAuthenticationFilter loginAuthenticationFilter = new CaptchaAuthenticationFilter();
    loginAuthenticationFilter.setAuthenticationManager(authenticationManager());
    loginAuthenticationFilter.setAuthenticationFailureHandler(authenticationFailureHandler());
....

http.authorizeRequests()

...

.addFilterBefore(loginAuthenticationFilter, UsernamePasswordAuthenticationFilter.class)
...

自定义的跳转url，方便前端进行友好提示

    @Bean
    public AuthenticationFailureHandler authenticationFailureHandler() {
        ExceptionMappingAuthenticationFailureHandler failureHandler = new ExceptionMappingAuthenticationFailureHandler();
        Map<String, String> failureUrlMap = new HashMap<>();
        failureUrlMap.put(BadCredentialsException.class.getName(), LoginAuthenticationFailureHandler.PASS_ERROR_URL);
        failureUrlMap.put(CaptchaException.class.getName(), LoginAuthenticationFailureHandler.CODE_ERROR_URL); failureUrlMap.put(AccountExpiredException.class.getName(), LoginAuthenticationFailureHandler.EXPIRED_URL); failureUrlMap.put(LockedException.class.getName(), LoginAuthenticationFailureHandler.LOCKED_URL); failureUrlMap.put(DisabledException.class.getName(), LoginAuthenticationFailureHandler.DISABLED_URL); failureHandler.setExceptionMappings(failureUrlMap); return failureHandler; }

或XML配置：

在配置文件中配置CaptchaAuthenticationFilter

<bean id="captchaAuthenticaionFilter" class="com.zrhis.system.security.CaptchaAuthenticationFilter">  
    <property name="authenticationManager" ref="authenticationManager" />  
    <property name="authenticationFailureHandler" ref="authenticationFailureHandler" />  
    <property name="authenticationSuccessHandler" ref="authenticationSuccessHandler" />  
    <property name="filterProcessesUrl" value="/login.do" />  
</bean>  

<bean id="authenticationSuccessHandler" class="com.zrhis.system.security.SimpleLoginSuccessHandler">  
    <property name="defaultTargetUrl" value="/WEB-INF/app.jsp"></property>  
    <property name="forwardToDestination" value="true"></property>  
</bean>  
<bean id="authenticationFailureHandler" 
      class="org.springframework.security.web.authentication.SimpleUrlAuthenticationFailureHandler">  
    <property name="defaultFailureUrl" value="/login.jsp" />  
</bean>

从配置文件中就可以看出来authenticationManager、authenticationFailureHandler、authenticationSuccessHandler、filterProcessesUrl等都需要我们自行注入了。

filterProcessesUrl定义的是登录验证的地址，默认的是j_spring_security_check这里我们改成login.do

authenticationSuccessHandler中的defaultTargetUrl定义的是登录成功后跳转到的页面

authenticationFailureHandler中的defaultTargetUrl定义的是登录失败后跳转到的页面

我们的首页app.jsp在/WEB-INF下所以需要使用服务器跳转，所以需要将forwardToDestination设为true，因为客户端跳转是不能直接访问WEB-INF下的内容的。

最后在http中将FORM_LOGIN_FILTER替换掉，最终http中完整的配置就变成了下面的内容

<sec:http access-decision-manager-ref="accessDecisionManager"  
    entry-point-ref="authenticationEntryPoint">  

    <sec:access-denied-handler ref="accessDeniedHandler"/>  

    <sec:session-management invalid-session-url="/login.jsp" />  

    <sec:custom-filter ref="filterSecurityInterceptor" before="FILTER_SECURITY_INTERCEPTOR"/>  
    <sec:custom-filter ref="captchaAuthenticaionFilter" position="FORM_LOGIN_FILTER"/>  
</sec:http>

custom-filter中before是在这个filter之前，after是之后，position是替换。

　在使用Spring Security框架过程中，经常会有这样的需求，即在登录验证时，附带增加额外的数据，如验证码、用户类型等。下面将介绍如何实现。

　　注：我的工程是在Spring Boot框架基础上的，使用xml方式配置的话请读者自行研究吧。

实现自定义的WebAuthenticationDetails

　　该类提供了获取用户登录时携带的额外信息的功能，默认实现WebAuthenticationDetails提供了remoteAddress与sessionId信息。开发者可以通过Authentication的getDetails()获取WebAuthenticationDetails。我们编写自定义类CustomWebAuthenticationDetails继承自WebAuthenticationDetails，添加我们关心的数据（以下是一个token字段）。

package com.courses.service;

import javax.servlet.http.HttpServletRequest;

import org.springframework.security.web.authentication.WebAuthenticationDetails;

public class CustomWebAuthenticationDetails extends WebAuthenticationDetails {
    /**
     * 
     */
    private static final long serialVersionUID = 6975601077710753878L;
    private final String token;

    public CustomWebAuthenticationDetails(HttpServletRequest request) {
        super(request);
        token = request.getParameter("token");
    }

    public String getToken() {
        return token;
    }

    @Override
    public String toString() {
        StringBuilder sb = new StringBuilder();
        sb.append(super.toString()).append("; Token: ").append(this.getToken());
        return sb.toString();
    }
}

　　注：在登录页面，可将token字段放在form表单中，也可以直接加在url的参数中，进而把额外数据发送给后台。

实现自定义的AuthenticationDetailsSource

　　该接口用于在Spring Security登录过程中对用户的登录信息的详细信息进行填充，默认实现是WebAuthenticationDetailsSource，生成上面的默认实现WebAuthenticationDetails。我们编写类实现AuthenticationDetailsSource，用于生成上面自定义的CustomWebAuthenticationDetails。

package com.courses.service;

import javax.servlet.http.HttpServletRequest;

import org.springframework.security.authentication.AuthenticationDetailsSource;
import org.springframework.security.web.authentication.WebAuthenticationDetails;
import org.springframework.stereotype.Component;

@Component
public class CustomAuthenticationDetailsSource implements AuthenticationDetailsSource<HttpServletRequest, WebAuthenticationDetails> {

    @Override
    public WebAuthenticationDetails buildDetails(HttpServletRequest context) {
        return new CustomWebAuthenticationDetails(context);
    }
}

配置使用自定义的AuthenticationDetailsSource

　　只要看这一句.formLogin().authenticationDetailsSource(authenticationDetailsSource)

    @Autowired
    private AuthenticationDetailsSource<HttpServletRequest, WebAuthenticationDetails> authenticationDetailsSource;

    protected void configure(HttpSecurity http) throws Exception {
        http
            .headers()
                .cacheControl()
                .contentTypeOptions()
                .httpStrictTransportSecurity()
                .xssProtection()
                .and()
            .authorizeRequests()
                .antMatchers(
                    "/css/**",
                    "/js/**")
                .permitAll()
                .antMatchers("/**")
                .authenticated()
                .and()
            .formLogin()
                .loginPage("/login")
                .permitAll()
                .defaultSuccessUrl("/todo.html", true)
                .authenticationDetailsSource(authenticationDetailsSource)
            .and()
                .logout()
                .logoutUrl("/logout")
                .logoutRequestMatcher(new AntPathRequestMatcher("/logout"))
                .logoutSuccessUrl("/login")
                .and()
            .csrf().disable();
    }

实现自定义的AuthenticationProvider

　　AuthenticationProvider提供登录验证处理逻辑，我们实现该接口编写自己的验证逻辑。

package com.courses.service;

import org.springframework.security.authentication.AuthenticationProvider;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.AuthenticationException;
import org.springframework.stereotype.Component;

@Component
public class CustomAuthenticationProvider implements AuthenticationProvider {
    
    @Override
    public Authentication authenticate(Authentication authentication) 
            throws AuthenticationException {
        CustomWebAuthenticationDetails details = (CustomWebAuthenticationDetails) authentication.getDetails();  // 如上面的介绍，这里通过authentication.getDetails()获取详细信息
        // System.out.println(details); details.getRemoteAddress(); details.getSessionId(); details.getToken();
        // 下面是验证逻辑，验证通过则返回UsernamePasswordAuthenticationToken，
        // 否则，可直接抛出错误（AuthenticationException的子类，在登录验证不通过重定向至登录页时可通过session.SPRING_SECURITY_LAST_EXCEPTION.message获取具体错误提示信息）
        if (验证通过) {
            return UsernamePasswordAuthenticationToken(省略参数);
        } else {
            throw new AuthenticationException的子类("你要显示的错误信息")
        }
    }

    @Override
    public boolean supports(Class<?> authentication) {
        return authentication.equals(UsernamePasswordAuthenticationToken.class);
    }

}

配置使用自定义的AuthenticationProvider

　　@Autowired
    private AuthenticationProvider authenticationProvider; 

　　@Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(authenticationProvider);
    }

http://www.cnblogs.com/phoenix-smile/p/5666686.html

    @Bean
    public AuthenticationFailureHandler authenticationFailureHandler() {
        ExceptionMappingAuthenticationFailureHandler failureHandler = new ExceptionMappingAuthenticationFailureHandler();
        Map<String, String> failureUrlMap = new HashMap<>();
        failureUrlMap.put(AccountExpiredException.class.getName(), LoginAuthenticationFailureHandler.EXPIRE_URL);
        failureUrlMap.put(BadCredentialsException.class.getName(), LoginAuthenticationFailureHandler.PASS_ERROR_URL);
        failureUrlMap.put(CaptchaException.class.getName(), LoginAuthenticationFailureHandler.KAPTCHA_ERROR_URL);
        failureHandler.setExceptionMappings(failureUrlMap);
        return failureHandler;
    }
