今天在调试一个基础的Struts2框架小程序。总是提示"There is no Action mapped for namespace / and action name"的错误。上网查询后发现这是一个初学者经常碰到的问题,导致错误的原因主要有两种。总结如下:
一、struts.xml文件错误。这种错误又分为以下几种:1,struts.xml文件名错误。一定要注意拼写问题;2,struts.xml文件放置路径错误。一定要将此文件放置在src目录下。编译成功后,要确认是否编译到classes目录中;3,struts.xml文件内容错误。下面给出一个正确的struts.xml文件以供参考。注意背景色部分。
