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;

    }

package com.tangcheng.app.rest.security;

import com.tangcheng.app.domain.exception.CaptchaException;

import org.springframework.security.core.AuthenticationException;

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

import javax.servlet.ServletException;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import java.io.IOException;

/**

 * Created by tangcheng on 5/21/2017.

 */

public class LoginAuthenticationFailureHandler extends SimpleUrlAuthenticationFailureHandler {

    public static final String PASS_ERROR_URL = "/login?error";

    public static final String CODE_ERROR_URL = "/login?code";

    public static final String EXPIRED_URL = "/login?expire";

    public static final String DISABLED_URL = "/login?disabled";

    public static final String LOCKED_URL = "/login?locked";

    @Override

    public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException, ServletException {

        if (exception instanceof CaptchaException) {

            getRedirectStrategy().sendRedirect(request, response, CODE_ERROR_URL);

        } else {

            getRedirectStrategy().sendRedirect(request, response, PASS_ERROR_URL);

        }

    }

}

https://github.com/helloworldtang/spring-boot-cookbook/blob/master/app/src/main/java/com/tangcheng/app/api/rest/security/LoginAuthenticationFailureHandler.java

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;

    }
