java spring-mvc + maven + hibernate + mysql 注释

1.新建maven项目

2.选择webapp

3.若是项目没有 src/main/java 则在下图中新建main下新建java文件夹

4.在 src/main/java 文件夹下 新建 cn.com.test 包

5.右键 properties => project facets 发现 dynamic web module 是 2.3 并且无法修改

6.到项目根目录,修改下图文件,jst.web 2.3 改为 3.0

7.修改 pom.xml

11.在 web-info 下新建views文件夹,在views文件夹下新建index.jsp

12.项目结构如下图

13.项目添加到tomcat下
