本文详细介绍了如何将Spring与MyBatis进行整合，包括在`spring-dao.xml`中配置数据源、SqlSessionFactory、SqlSessionTemplate以及Mapper接口的实现。通过这种方式，每次调用Mapper接口的方法时，都会自动创建并使用SqlSession。此外，还展示了POM.xml文件中的依赖配置，确保所有必要的库都已引入。

UserMapper.java: (接口)

UserMapper.xml: (实现接口，关联实体类，编写sql语句，注册到spring-dao.xml)

mybatis-config.xml:

spring-dao.xml:

UserMapperImpl.java:

spring-dao.xml 添加userMapper bean，将 sqlSession 对象注入，这样每次userMapper实例化，都会自动创建sqlSession:

Test.java: 测试类中实例化 userMapper Bean，调用具体的方法：

spring-dao.xml VS 整合之前：MybatisUtil.java 引入 mybatis-config.xml:
mybatis-config.xml:
MybatisUtil.java：

对比整合之前：Test.java:

配置事务：
