启动项目时报以下异常

严重: Exception loading sessions from persistent storage

java.io.EOFException

 

遇到上述异常，删除Tomcat里面的work\Catalina\localhost下的项目文件内容即可解决.

原因是由于项目测试中class文件或者其它文件更新过频繁。

 

 

之前经常碰到页面修改后，重新发布的项目页面还是原样，不管删掉tomcat/webapps/发布的项目还是重新部署，都无法显示修改后的效果，

但是其他页面修改后又能显示。真是莫名其妙。

现在才知道是tomcat的问题，同样删除Tomcat里面的work\Catalina\localhost下的项目文件内容即可解决.
