Mybatis与Spring的整合步骤

第一步：导入jar包

第二步：创建两个Source Folder文件夹（ resources和test）

第三步：创建实体类

第四步：创建dao层接口、实现类、mapper映射文件

1、Dao接口：

package com.bdqn.dao.user;

import java.util.List;

import com.bdqn.pojo.User;

public interface UserMapper {

	/**
	 * 按照用户名和用户角色查找用户列表
	 * @param user
	 * @return
	 */
	List getUsers(User user);
}

2、Dao的实现类：

package com.bdqn.dao.user;

import java.util.List;
import org.mybatis.spring.SqlSessionTemplate;
import com.bdqn.pojo.User;

public class UserMapperImpl implements UserMapper {
	private SqlSessionTemplate sqlSession;

	@Override
	public List getUsers(User user) {
		return sqlSession.selectList("com.bdqn.dao.user.UserMapper.getUserList",user);
	}

	public SqlSessionTemplate getSqlSession() {
		return sqlSession;
	}

	public void setSqlSession(SqlSessionTemplate sqlSession) {
		this.sqlSession = sqlSession;
	}

}

3、UserMapper文件：

	
		SELECT * FROM `smbms_user` 
		
			
				and userName LIKE CONCAT('%',#{userName},'%') 
			
			
			 	AND `userRole` =#{userRole}
			
		 
	

 

第五步：创建service层接口、实现类

Service接口

package com.bdqn.service;

import java.util.List;

import com.bdqn.pojo.User;

public interface UserService {

	List findUserList(User user) throws Exception;
}

Service实现类

package com.bdqn.service;

import java.util.List;

import com.bdqn.dao.user.UserMapper;
import com.bdqn.pojo.User;

public class UserServiceImpl implements UserService {

	private UserMapper userMapper;

	@Override
	public List findUserList(User user) throws Exception {
		try {
			return userMapper.getUsers(user);
		} catch (Exception e) {
			e.printStackTrace();
			throw e;
		}
	}

	public UserMapper getUserMapper() {
		return userMapper;
	}

	public void setUserMapper(UserMapper userMapper) {
		this.userMapper = userMapper;
	}

}

第六步：在resource文件夹中编写mybatis-config.xml

 

第七步：在resource文件夹中编写applicationContext.xml

         
         
         	
         	
         	
         	
         
         
         
         	
         	
         	
         	
         	
         	
         		
         			classpath:com/bdqn/dao/**/*.xml
         		
         	
         
         
         
         	
         
         
         	
         
         
         	
         

第八步：在test文件夹中编写测试方法
