关于 Spring Security 权限管理实现登录之前一篇文章

SpringBoot + Spring Security + Thymeleaf 实现权限管理登录 已经介绍了。


本文主要介绍在登录中加入验证码,关于验证码的使用,如下


SpringBoot中集成kaptcha验证码


先看效果图


一、Spring Security 的核心且唯一配置文件

  121.     }
  122. }



http.addFilterBefore(new KaptchaAuthenticationFilter("/login""/login?error"), UsernamePasswordAuthenticationFilter.class)

注意这里,addFilterBefore 表示在执行用户名和密码验证之前,先执行 KaptchaAuthenticationFilter 这个过滤器,这是一个我们自定义的过滤器,第一个参数表示登录页面路径,第二个是登录失败页面

下面给出 KaptchaAuthenticationFilter 的代码


二、验证码验证过滤器


KaptchaAuthenticationFilter.java
  1. package com.liuyanzhao.forum.filter;
  2. import com.google.code.kaptcha.Constants;
  3. import org.springframework.security.authentication.InsufficientAuthenticationException;
  4. import org.springframework.security.core.Authentication;
  5. import org.springframework.security.core.AuthenticationException;
  6. import org.springframework.security.web.authentication.AbstractAuthenticationProcessingFilter;
  7. import org.springframework.security.web.authentication.SimpleUrlAuthenticationFailureHandler;
  8. import javax.servlet.*;
  9. import javax.servlet.http.HttpServletRequest;
  10. import javax.servlet.http.HttpServletResponse;
  11. import java.io.IOException;
  12. /**
  13.  * @author 言曌
  14.  * @date 2018/5/4 下午12:36
  15.  */
  16. public class KaptchaAuthenticationFilter extends AbstractAuthenticationProcessingFilter {
  17.     private String servletPath;
  18.     public KaptchaAuthenticationFilter(String servletPath, String failureUrl) {
  19.         super(servletPath);
  20.         this.servletPath = servletPath;
  21.         setAuthenticationFailureHandler(new SimpleUrlAuthenticationFailureHandler(failureUrl));
  22.     }
  23.     @Override
  24.     public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
  25.         HttpServletRequest req = (HttpServletRequest) request;
  26.         HttpServletResponse res = (HttpServletResponse) response;
  27.         if ("POST".equalsIgnoreCase(req.getMethod()) && servletPath.equals(req.getServletPath())) {
  28.             String expect = (String) req.getSession().getAttribute(Constants.KAPTCHA_SESSION_KEY);
  29.             if (expect != null && !expect.equalsIgnoreCase(req.getParameter("kaptcha"))) {
  30.                 unsuccessfulAuthentication(req, res, new InsufficientAuthenticationException("输入的验证码不正确"));
  31.                 return;
  32.             }
  33.         }
  34.         chain.doFilter(request, response);
  35.     }
  36.     @Override
  37.     public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException, IOException, ServletException {
  38.         return null;
  39.     }
  40. }

第37行req.getParameter("kaptcha"),其中 kaptcha 是登录表单中验证码输入框的 name


三、视图层


我这里是在任何页面点击登录按钮,弹出模态框登录框。然后通过 ajax 验证

HTML
  1. <section class="box-login v5-input-txt" id="box-login">
  2.                   <form id="login_form" th:action="@{/login}" method="post" autocomplete="off">
  3.                       <ul>
  4.                           <li class="form-group">
  5.                               <input class="form-control" type="text" min="4" maxlength="20"
  6.                                      name="username" placeholder="请输入用户名或邮箱" required>
  7.                           </li>
  8.                           <li class="form-group">
  9.                               <input class="form-control" type="password" minlength="6" maxlength="100"
  10.                                      id="password" name="password" placeholder="请输入密码" required>
  11.                           </li>
  12.                           <li class="form-group">
  13.                               <input type="text" class="form-control pull-left margin-r-5" name="kaptcha"
  14.                                      style="width: 50%;" placeholder="验证码">
  15.                               <img th:src="@{/getKaptchaImage}" width="80" height="34"
  16.                                    class="captcha changeCaptcha pull-left margin-r-5" alt="验证码"/>
  17.                               <a href="javascript:void(0)" class="changeCaptcha">换一张</a>
  18.                               <div class="clear"></div>
  19.                           </li>
  20.                           <li class="form-group">
  21.                               <label>
  22.                                   <input type="checkbox" name="remember-me" checked> 下次自动登录</a>
  23.                               </label>
  24.                           </li>
  25.                       </ul>
  26.                   </form>
  27.                   <p class="good-tips marginB10">
  28.                       <a class="fr" th:href="@{/forget}" target="_blank">忘记密码?</a>还没有账号?
  29.                       <a th:href="@{/register}" target="_blank" id="btnRegister">立即注册</a>
  30.                   </p>
  31.                   <div class="marginB10">
  32.                       <button id="login_btn" type="button" class="btn btn-micv5 btn-block globalLogin">
  33.                           登录
  34.                       </button>
  35.                       <div id="login-form-tips" class="tips-error bg-danger" style="display: none;">错误提示
  36.                       </div>
  37.                   </div>
  38.                   <div class="threeLogin"><span>其他方式登录</span>
  39.                       <a class="nqq" href="javascript:;"></a>
  40.                       <a class="nwx" href="javascript:;"></a>
  41.                   </div>
  42.               </section>



JS
  1. $(document).on("click""#login_btn"function () {
  2.        var randomAnim = Math.floor(Math.random() * 7);
  3.        var _ctx = $("meta[name='ctx']").attr("content");
  4.        var token = $("meta[name='_csrf']").attr("content");
  5.        var header = $("meta[name='_csrf_header']").attr("content");
  6.        $.ajax({
  7.            url: _ctx + "/login",
  8.            type: 'POST',
  9.            data: $("#login_form").serialize(),
  10.            beforeSend: function (request) {
  11.                request.setRequestHeader(header, token);
  12.            },
  13.            success: function (data) {
  14.                console.log(data);
  15.                if (data.status == 'ok') {
  16.                    //登录成功
  17.                    window.location.reload();
  18.                } else if (data.status == 'error') {
  19.                    layer.alert("用户名或密码错误!", {icon: 2, anim: randomAnim});
  20.                } else {
  21.                    layer.alert("验证码错误", {icon: 2, anim: randomAnim});
  22.                }
  23.            },
  24.            error: function () {
  25.                layer.msg("出现错误,请尝试刷新页面!", {icon: 2, anim: 6});
  26.            }
  27.        });
  28.        return false;
  29.    });

layer.alert()这个不用管,是引入了 layui 的插件。



验证码的创建请参考 SpringBoot中集成kaptcha验证码
