最近專案中用到redis儲存tomcat共享session。不知什麼原因出現異常。問題解決了，做一下記錄：

tomcat 的conf/context.xml配置為
<Valve className="com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve" />
        <Manager className="com.orangefunction.tomcat.redissessions.RedisSessionManager" 
                host="192.168.1.42" 
                port="6379" 
                database="0"
                maxInactiveInterval="60"/>
通過檢查發現，redis增加密碼了。隨後把該配置項改為
<Valve className="com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve" />
        <Manager className="com.orangefunction.tomcat.redissessions.RedisSessionManager" 
                host="192.168.1.42" 
                port="6379" 
                database="0"
                password="123" 
                maxInactiveInterval="60"/>
就沒有問題了。
