 这几天在学习java web中的SSh架构,开始搭建时候遇到很多问题,经过几天的探索,记录一下SSH 的搭建

一.使用Idea创建新项目

1.选择Spring相关

2.struts2相关


3.hibernate相关


4.选择完成后next->finish

二.在项目web/WEB-INF目录下创建lib 和classe文件夹将相关的jar包导入项目
三.依赖jar包


四调整项目依赖路径


选择放jar包的lib文件夹


点击OK


然后apply->ok
四.配置tomcat


五.测试修改

报错1.运行项目报错,错误如下

这个错误是因为web.xml中的structs2 配置错误 


修改配置为:

        struts2
        org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter
    
    
        struts2
        /*
