[Usher丶AckMan]

错误帮你翻译一下,应该是struts2的拦截器配置有问题,你看一下struts2.xml文件

[用户名无法显示]

log4j的jar包没加进去

[qq159357258]

这是我的struts文件，应该是这样配置没错啊！？

: Exception starting filter struts2 Caused by: Unable to load configuration. - [unknown location] Caused by: Parent package is not defined: default - [unknown location] 明显struts2需要的包没导入啊 ，你把需要的包导进去在试下
