eclipse 用maven搭建ssh框架

Maven + Spring + Spring MVC +Hibernate

首先

选择Maven--》Maven Project

点击Next

选中如图所示，点击Next

将Group Id ，Artifact Id 填入Package可以手动清空（我填的Group Id：com.ssh02 ， Artifact Id：ssh02）；然后点击finish。、

刚建好的工程目录如下图：

这时候右击项目名，选择Build Path--》Configure Build Path

选中JRE System Library[J2EE 1.5]点击Remove，然后再点击Order and Export ，勾选Maven Dependencies

点击Apply 然后点击ok。工程目录结构变成如下图

右击项目名，选择Properties--》Project Facets

取消勾选Dynamic Web Module ， java 改为1.8，点击右上角Runtimes 勾选tomcat 9.0（我用的是9.0）。还是右击项目名，选择Properties--》Project Facets

此时 Dynamic Web Module版本变成了3.0，勾选它，然后会出现Further configuration avalilable

点击Further configuration avalilable，输入如下图

点击ok，Apply ，ok；工程目录结构如下

整个工程版本，以及目录文件已经完全弄好，接着配置pom文件，代码如下

第一次写，有不足的地方请大家加以纠正。
