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21-Aug-2018 14:26:38.160 警告 [RMI TCP Connection(3)-127.0.0.1] org.apache.tomcat.util.descriptor.web.WebXml.setVersion Unknown version string [4.0]. Default version will be used.

contextConfigLocation
classpath:spring-config.xml
启动项目,启动成功,完成ssh的基本配置
