jar包：

配置文件：
myBatis-conf.xml

applicationContext.xml

DeptMapper.xml

    
        
        
        
    

    
        insert into dept_t(dept_name,dept_address) values(#{deptName},#{deptAddress})
    

类：

package com.xxjqr.dao.impl;

import javax.annotation.Resource;

import org.mybatis.spring.SqlSessionTemplate;
import org.springframework.stereotype.Repository;

import com.xxjqr.dao.DeptDao;
import com.xxjqr.entity.Dept;

import lombok.Data;

@Repository("deptDao")
@Data
public class DeptDaoImpl implements DeptDao {

    @Resource
    private SqlSessionTemplate sqlSessionTemplate;
    
    public int insertDept(Dept dept) {
        //命名空间+sqlId
        return sqlSessionTemplate.insert("com.xxjqr.entity.DeptMapper.insertDept",dept);
    }

}

package com.xxjqr.service.impl;


import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import com.xxjqr.dao.DeptDao;
import com.xxjqr.entity.Dept;
import com.xxjqr.service.DeptService;

import lombok.Data;

@Service("deptService")
@Data
public class DeptServiceImpl implements DeptService {
    
    @Resource
    private DeptDao deptDao;
    
    public int insertDept(Dept dept) {
        deptDao.insertDept(dept);
        return 0;
    }

}

package com.xxjqr.Test;

import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.xxjqr.entity.Dept;
import com.xxjqr.service.DeptService;

public class App {
    
    
    @Test
    public void testInsertDept(){
        ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml",App.class);
        DeptService deptService = (DeptService)ac.getBean("deptService");

        Dept dept = new Dept();
        dept.setDeptName("开发部");
        dept.setDeptAddress("贵州");
        System.out.println("受影响行数:"+deptService.insertDept(dept));
    }
}

优化

1. 优化别名
myBatis-conf.xml中修改

2. 优化sql映射文件的加载
myBatis-conf.xml中

Paste_Image.png

applicationContext.xml中修改

3. 优化dao实现

    
        
        
        
    

    
    
        insert into dept_t(dept_name,dept_address) values(#{deptName},#{deptAddress})
    

使用该配置后，就无需Dao接口的实现了，因为框架会自动将dao接口的代理对象并注入到spring容器中；
DeptServiceImpl会通过@Autowired将代理对象注入到“dao接口”引用
