shiro表单的验证自定义FormAuthenticationFilter

验证码思路；shiro使用FormAuthenticationFilter进行表单认证，验证校验的功能应该加在FormAuthenticationFilter中，在认证之前进行验证码校验。
    
    需要写FormAuthenticationFilter的子类，继承FormAuthenticationFilter，改写它的认证方法，在认证之前进行验证码校验。
    
    自定义FormAuthenticationFilter
    [html] view plain copy
    package cn.me.ssm.shiro;  
      
    import javax.servlet.ServletRequest;  
    import javax.servlet.ServletResponse;  
    import javax.servlet.http.HttpServletRequest;  
    import javax.servlet.http.HttpSession;  
      
    import org.apache.shiro.web.filter.authc.FormAuthenticationFilter;  
      
    public class CustomFormAuthenticationFilter extends FormAuthenticationFilter {  
      
        @Override  
        protected boolean onAccessDenied(ServletRequest request, ServletResponse response) throws Exception {  
            // 在这里进行验证码的校验  
            HttpServletRequest httpServletRequest = (HttpServletRequest) request;  
            HttpSession session = httpServletRequest.getSession();  
      
            // 取出验证码  
            String validateCode = (String) session.getAttribute("validateCode");  
            // 取出页面的验证码  
            // 输入的验证和session中的验证进行对比  
            String randomcode = httpServletRequest.getParameter("randomcode");  
            if (randomcode != null && validateCode != null && !randomcode.equals(validateCode)) {  
                // 如果校验失败，将验证码错误失败信息，通过shiroLoginFailure设置到request中  
                httpServletRequest.setAttribute("shiroLoginFailure", "randomCodeError");  
                // 拒绝访问，不再校验账号和密码  
                return true;  
            }  
            return super.onAccessDenied(request, response);  
        }  
    }  
    
    spirng-shiro.xml修改
    [html] view plain copy
      
        <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">  
              
            <property name="securityManager" ref="securityManager" />  
              
            <property name="loginUrl" value="/login.do" />  
              
            <property name="successUrl" value="/first.do" />  
              
            <property name="unauthorizedUrl" value="/refuse.jsp" />  
      
              
            <property name="filters">  
                <map>  
                      
                    <entry key="authc" value-ref="formAuthenticationFilter" />  
                </map>  
            </property>  
      
              
            <property name="filterChainDefinitions">  
                <value>  
                      
                      
                    /images/** = anon  
                    /js/** = anon  
                    /styles/** = anon  
                      
                    /validatecode.jsp = anon  
      
                      
                    /logout.action = logout  
                      
                      
                      
                    /**=authc  
      
                </value>  
            </property>  
        </bean>  
      
          
          
        <bean id="formAuthenticationFilter" class="cn.me.ssm.shiro.CustomFormAuthenticationFilter ">  
              
            <property name="usernameParam" value="username" />  
              
            <property name="passwordParam" value="password" />  
        </bean>  
    
    
    在login.do对验证错误 进行解析
    [html] view plain copy
    //登陆提交地址，和applicationContext-shiro.xml中配置的loginurl一致  
        @RequestMapping("/login")  
        public String login(HttpServletRequest request) throws Exception {  
      
            // 如果登录失败从request中获取认证异常信息，shiroLoginFailure就是shiro异常类的全限定名  
            // 根据shiro返回的异常类路径判断，抛出指定异常信息  
            String exceptionClassName = (String) request.getAttribute("shiroLoginFailure");  
            if (exceptionClassName != null) {  
                if (UnknownAccountException.class.getName().equals(exceptionClassName)) {  
                    throw new CustomException("用户名不存在");  
                } else if (IncorrectCredentialsException.class.getName().equals(exceptionClassName)) {  
                      
                    throw new CustomException("用户名/密码不正确");  
                }else if("randomCodeError".equals(exceptionClassName)){  
                    throw new CustomException("验证码错误 ");  
                }else {  
                    throw new Exception();// 最终在异常处理器生成未知错误  
                }  
            }  
            // 此方法不处理登陆成功（认证成功），shiro认证成功会自动跳转到上一个请求路径  
            // 登陆失败还到login页面  
            return "login";  
        }  
    
    
    记住我
    用户登陆选择“自动登陆”本次登陆成功会向cookie写身份信息，下次登陆从cookie中取出身份信息实现自动登陆。
    用户身份实现Java.io.Serializable接口
    向cookie记录身份信息需要用户身份信息对象实现序列化接口，如下：
    [html] view plain copy
    package cn.me.ssm.po;  
      
    import java.io.Serializable;  
    import java.util.List;  
      
    /**  
     * 用户身份信息  
     *   
     * @author Administrator  
     *  
     */  
    public class ActiveUser implements Serializable {  
        /**  
         *   
         */  
        private static final long serialVersionUID = -60165487594776678L;  
        private String userid;// 用户id  
        private String usercode;// 用户帐号  
        private String username;// 用户名称  
      
        private List<SysPermission> menus;// 用户的菜单  
        private List<SysPermission> permissions;// 权限  
      
        public String getUserid() {  
            return userid;  
        }  
      
        public void setUserid(String userid) {  
            this.userid = userid;  
        }  
      
        public String getUsercode() {  
            return usercode;  
        }  
      
        public void setUsercode(String usercode) {  
            this.usercode = usercode;  
        }  
      
        public String getUsername() {  
            return username;  
        }  
      
        public void setUsername(String username) {  
            this.username = username;  
        }  
      
        public List<SysPermission> getMenus() {  
            return menus;  
        }  
      
        public void setMenus(List<SysPermission> menus) {  
            this.menus = menus;  
        }  
      
        public List<SysPermission> getPermissions() {  
            return permissions;  
        }  
      
        public void setPermissions(List<SysPermission> permissions) {  
            this.permissions = permissions;  
        }  
      
    }
