篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了实习小结--- SSM框架搭建（Maven项目）相关的知识，希望对你有一定的参考价值。

之前分享了一个普通的SSM框架的搭建方法，感觉还是过于老套，现在都流行使用Maven来管理项目，在这分享一个使用Maven搭建的SSM（SpringMVC+Spring+MyBatis）

1、首先maven项目的最重要的部分是在pom.xml中添加依赖

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

2、在resources下存放一些配置文件信息，包括MyBatis中的实体类映射文件

（1）applicationContext.xml是Spring的配置文件，其中包括了连接数据库，配置mybatis的sqlSessionFactory，dao接口，事务，以及Shiro，aop的配置

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