SSM_006.idea新建ssm项目并修改web版本

其他 2019-03-20 19:31:19 阅读次数: 0

idea自带maven插件，可以自己安装配置maven或者使用idea自带的，建议maven配置镜像地址。 

初始化后，右击项目，选择Open module Setting，先删除web文件，然后选择新版，这里选择3.1

右击main，新建文件夹java，右击新建的java文件夹，选择make directory as Sources Root；同理新建resources文件夹，标记为resource Root。

添加项目需要的jar包依赖

配置web.xml文件

在web.xml同级目录下新建dispatcher-servlet.xml文件，配置SpringMVC

<?xml version='1.0' encoding='UTF-8' ?>
