Spring和MyBatis整合(注解版)

1.導入所需要的依賴

<!--MyBatis和Spring的整合包 由MyBatis提供-->
<dependency>
  <groupId>org.mybatis</groupId>
  <artifactId>mybatis-spring</artifactId>
  <version>1.3.0</version>
</dependency>
<!--MyBatis的核心jar文件-->
<dependency>
  <groupId>org.mybatis</groupId>
  <artifactId>mybatis</artifactId>
  <version>3.4.1</version>
</dependency>

2.entity實體類

 

 3.dao層接口

 

 4.service接口

 

 5.serviceimpl實現類

 

 6.Dao.xml配置

 

 7.jdbc.properties配置

 

 8.applicationContext.xml大配置文件
