本文主要是介绍Shiro和Spring结合对请求路径进行过滤和记住我过滤操作，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
一，请求路径的过滤器
SessionExpireFilter.java如下：
package com.innotek.core.support.filter;import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;import org.apache.shiro.subject.Subject;
import org.apache.shiro.web.filter.AccessControlFilter;import com.innotek.core.Constants;/********* 会话超时控制过滤器** @author qiuzq* <p/>* 类功能： 用于ajax和普通请求，会话超时情况下：* 1. ajax进行全局监测complete事件，浏览器通过发现SESSIONSTATUS=TIMEOUT，采取跳转。* 2. 普通请求直接进行redirect。*/public class SessionExpireFilter extends AccessControlFilter {// @Autowired// private UserService userService;@Overrideprotected boolean preHandle(ServletRequest request, ServletResponse response) throws Exception {HttpServletRequest req = (HttpServletRequest) request;HttpServletResponse resp = (HttpServletResponse) response;HttpSession session = req.getSession();// 判断session是否失效if (session.getAttribute(Constants.CURRENT_USER) != null) {return true;}// contextPathString cxtPath = req.getContextPath();// XMLHttpRequestString type = req.getHeader("X-Requested-With") == null ? "" : req.getHeader("X-Requested-With");// BASEPATHString basePath = req.getScheme() + "://" + req.getServerName() + ":" + req.getServerPort() + cxtPath + "/";if (type.equals("XMLHttpRequest")) {// 处理ajax请求, 设置响应header：超时标识以及重定向路径resp.setHeader("SESSIONSTATUS", "TIMEOUT");resp.setHeader("CONTEXTPATH", basePath + "login.jsp");// 处理ajax请求, 设置状态 为403 未授权resp.setStatus(HttpServletResponse.SC_FORBIDDEN);} else {// 普通请求直接进行redirectresp.sendRedirect(cxtPath + "/login.jsp?TIME_OUT_REQ=1");}//WEB服务上其他受控资源。return false;}@Overrideprotected boolean isAccessAllowed(ServletRequest request, ServletResponse response, Object mappedValue)throws Exception {return true;}@Overrideprotected boolean onAccessDenied(ServletRequest request, ServletResponse response) throws Exception {return true;}}
二，shiro.xml的文件配置如下：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:util="http://www.springframework.org/schema/util"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:dubbo="http://code.alibabatech.lily.com/schema/dubbo"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsdhttp://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util.xsdhttp://code.alibabatech.lily.com/schema/dubbo http://code.alibabatech.lily.com/schema/dubbo/dubbo.xsd"><!-- 拦截器使用对象,使用Spring注入 --><dubbo:reference id="sysUserProvider" interface="com.innotek.provider.sys.SysUserProvider" check="false"/><!-- 这里主要是设置自定义的单Realm应用,若有多个Realm,可使用'realms'属性代替 --><bean id="realm" class="com.innotek.core.support.shiro.Realm"/><bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager"><property name="realm" ref="realm"/></bean><!-- 记录菜单 --><bean id="rememberMenuFilter" class="com.innotek.core.support.filter.RememberMenuFilter"><property name="redirectUrl" value="/login.jsp"/></bean><bean id="sessionExpireFilter" class="com.innotek.core.support.filter.SessionExpireFilter" /><!-- Web应用中,Shiro可控制的Web请求必须经过Shiro主过滤器的拦截,Shiro对基于Spring的Web应用提供了完美的支持 --><bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean"><!-- Shiro的核心安全接口,这个属性是必须的 --><property name="securityManager" ref="securityManager"/><!-- 要求登录时的链接 --><property name="loginUrl" value="/login.jsp"/><!-- 用户访问未对其授权的资源时,所显示的连接 --><property name="unauthorizedUrl" value="/forbidden"/><!-- Shiro连接约束配置,即过滤链的定义 --><!-- anon：它对应的过滤器里面是空的,什么都没做 --><!-- authc：该过滤器下的页面必须验证后才能访问,它是Shiro内置的一个拦截器org.apache.shiro.web.filter.authc.FormAuthenticationFilter --><property name="filters"><util:map><entry key="rememberMenu" value-ref="rememberMenuFilter"></entry><entry key="sessionExpire" value-ref="sessionExpireFilter"></entry></util:map></property><property name="filterChainDefinitions"><value>/login.jsp = anon/login=anon/noPermission.jsp = anon/sunflower/bill/getParkFee*=anon/logout = anon/*.ico=anon/upload/*=anon/theme/**=anon/unauthorized=anon/forbidden=anon/**=user,sessionExpire,authc,perms,rememberMenu</value></property></bean><bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/>
</beans>三、记住点击过的菜单
RememberMenuFilter.java如下：
package com.innotek.core.support.filter;import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;import org.apache.log4j.Logger;
import org.apache.shiro.web.servlet.AdviceFilter;
import org.apache.shiro.web.util.WebUtils;import com.innotek.core.Constants;
import com.innotek.core.support.data.permission.model.UserSession;
import com.innotek.core.util.JsonUtil;
import com.innotek.core.util.RedisUtil;
import com.innotek.core.util.WebUtil;
import com.innotek.model.cfg.generator.Paramter;/**** 记住点击哪个菜单*/
public class RememberMenuFilter extends AdviceFilter {private static Logger logger = Logger.getLogger(RememberMenuFilter.class);private String redirectUrl = "/login.jsp";@Overrideprotected boolean preHandle(ServletRequest request, ServletResponse response) throws Exception {HttpServletRequest req = (HttpServletRequest) request;UserSession currentUserSession = WebUtil.getCurrentUserSession();if (currentUserSession == null) {WebUtils.issueRedirect(request, response, getRedirectUrl());return false;}//是否显示工作台Integer status = WebUtil.getCurrentUserSession().getShowStatus();req.getSession().setAttribute("showStatus", status);req.getSession().setAttribute("userName", currentUserSession.getUserName());String systemArray = JsonUtil.list2json(WebUtil.getCurrentUserSession().getSystemManageSession());req.getSession().setAttribute("systemList", systemArray);//返回工作台路径Paramter param = (Paramter) RedisUtil.getNoExpiry(Constants.PARAMTER_CACHE + "WORK_URL");if (param != null) {req.getSession().setAttribute("workUrl", param.getParamValue());}return true;}/*** 页面跳转** @return*/public String getRedirectUrl() {return redirectUrl;}public void setRedirectUrl(String redirectUrl) {this.redirectUrl = redirectUrl;}
}
四、然后再spring.xml配置文件中加入
<import resource="spring/shiro-cas.xml"/>
即可，
