### 错误原因： ###

这与Tomcat无法加载先前在早期关闭时保存的序列化Web会话有关。 这可能是因为Tomcat没有干净地关闭，因此会话对象在序列化过程中被破坏。

### 解决方法： ###

（一）  
 1、停止Tomcat  
 2、删除 \\apache-tomcat-8.5.31\\work\\Catalina\\localhost\\webname  
 下的 SESSIONS.ser 文件；  
 3、重启Tomcat

或者

（二）

编辑 \\apache-tomcat-8.5.31\\conf\\context.xml，设置`<Manager>`  
元素的pathname属性为空，关闭session持久化

<Manager pathname="" />
