配合哔哩哔哩视频学习【SSM 框架】SpringMVC+Spring+Mybatis SSM 整合+实战+源码7-10集
2.MyBatis整合Spring-有Mapper实现类
2.1.导入必须包
mybatis-spring
spring-ioc
spring-aop
spring-tx
spring-context
2.2.编写Mapper的实现类
接口:
package com.ssm.dao;
import com.ssm.domain.Customer;
public interface CustomerMapper {
/**
* 添加客户
*/
public void saveCustomer(Customer customer);
}
实现类:
package com.ssm.dao.impl;
import org.apache.ibatis.session.SqlSession;
import org.mybatis.spring.support.SqlSessionDaoSupport;
import com.ssm.dao.CustomerMapper;
import com.ssm.domain.Customer;
public class CustomerMapperImpl extends SqlSessionDaoSupport implements CustomerMapper {
public void saveCustomer(Customer customer) {
SqlSession sqlSession = this.getSqlSession();
sqlSession.insert("saveCustomer",customer);
//这里不需要事务的提交
}
}
2.3.编写applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
