最近项目遇到问题，shiro框异常退出没有清除缓存信息，服务器重启后，又拿旧的缓存session来登录，造成后台报错。

这里转载网友的文章，记录一下解决方法。大体就是重写sessionManager类，做一个清除操作。

配置默认会话管理器：

<bean id="sessionManager" class="com.xzjc.common.security.SimpleWebSessionManager"><property name="globalSessionTimeout" value="15000" /><property name="sessionValidationInterval" value="30000" /><property name="sessionValidationSchedulerEnabled" value="true" /></bean>

全局的会话信息设置成15秒,检测扫描信息间隔30秒,第三个参数就是是否开启扫描

重写管理器类的一个方法

package com.xzjc.common.security;import java.util.Collection;import java.util.Iterator;import org.apache.log4j.Logger;import org.apache.shiro.cache.CacheManager;import org.apache.shiro.session.ExpiredSessionException;import org.apache.shiro.session.InvalidSessionException;import org.apache.shiro.session.Session;import org.apache.shiro.session.mgt.DefaultSessionKey;import org.apache.shiro.session.mgt.SessionKey;import org.apache.shiro.session.mgt.SimpleSession;import org.apache.shiro.web.session.mgt.DefaultWebSessionManager;/** * 会话管理器，重写 * @author zhouyujie */public class SimpleWebSessionManager extends DefaultWebSessionManager {private CacheManager cacheManager;private final static Logger logger = Logger.getLogger(SimpleWebSessionManager.class);public SimpleWebSessionManager() {super();}public void validateSessions() {if (logger.isInfoEnabled()){logger.info("Validating all active sessions...");}int invalidCount = 0;Collection<?> activeSessions = getActiveSessions();if (activeSessions != null && !activeSessions.isEmpty()) {for (Iterator<?> i$ = activeSessions.iterator(); i$.hasNext();) {Session session = (Session) i$.next();try {SessionKey key = new DefaultSessionKey(session.getId());validate(session, key);} catch (InvalidSessionException e) {if (cacheManager != null) {SimpleSession s = (SimpleSession) session;if (s.getAttribute("portal.session.id") != null){cacheManager.getCache(null).remove(s.getAttribute("portal.session.id"));}}if (logger.isDebugEnabled()) {boolean expired = e instanceof ExpiredSessionException;String msg = (new StringBuilder()).append("Invalidated session with id [").append(session.getId()).append("]").append(expired ? " (expired)" : " (stopped)").toString();logger.debug(msg);}invalidCount++;}}}if (logger.isInfoEnabled()) {String msg = "Finished session validation.";if (invalidCount > 0){msg = (new StringBuilder()).append(msg).append("[").append(invalidCount).append("] sessions were stopped.").toString();}else{msg = (new StringBuilder()).append(msg).append("No sessions were stopped.").toString();}logger.info(msg);}}public void setCacheManager(CacheManager cacheManager) {this.cacheManager = cacheManager;}}

这样就好使了。
