1.添加基本的依赖坐标（项目如需有具体别的依赖，根据实际情况添加）
1 <!-- 统一管理jar包版本 -->
2 <properties>

4 <slf4j.version>1.6.6</slf4j.version>
5 <log4j.version>1.2.12</log4j.version>
6 <shiro.version>1.2.3</shiro.version>
7 <mysql.version>5.1.6</mysql.version>
8 <mybatis.version>3.4.5</mybatis.version>
9 <spring.security.version>5.0.1.RELEASE</spring.security.version>
10 </properties>
11 <!-- 锁定jar包版本 -->
