配合哔哩哔哩視訊學習【SSM 架構】SpringMVC+Spring+Mybatis SSM 整合+實戰+源碼7-10集
2.MyBatis整合Spring-有Mapper實作類
2.1.導入必須包
mybatis-spring
spring-ioc
spring-aop
spring-tx
spring-context
2.2.編寫Mapper的實作類
接口:
package com.ssm.dao;
import com.ssm.domain.Customer;
public interface CustomerMapper {
/**
* 添加客戶
*/
public void saveCustomer(Customer customer);
}
實作類:
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);
//這裡不需要事務的送出
}
}
2.3.編寫applicationContext.xml
