Spring 3.0.5+MyBatis3.0.4整合非完全例子

标签：3.0 Spring springframework MyBatis3.0 RELEASE org com public


基于注解的mybatis和spring整合:[url]http://huangmin001.iteye.com/blog/1185806[/url]
[color=red]这个文章说的很详细,很值得一看[/color].
Maven + SpringMVC + Mybatis【绝非原创，单纯整理】【四】: [url]http://playgod1984.iteye.com/blog/984113[/url] 最后面提示说id和映射关系.

考虑到MyBatis注解方式比较麻烦,可能都还没有xml来的方便,易读.所以就没有加上去.如有兴趣,自行参考[url]http://panyongzheng.iteye.com/blog/1604067[/url]


这个例子也很详细,但是并没有对Mapper接口和xml里面的sql id做映射.不过这是否是必须的?可以适当考虑.

[color=red]基于namespace接口与公用dao的区别[/color],从MyBatis3.0开始，对mapper中的namespace属性新增了一个特性：可以指定具体的接口来作为持久化操作类，在接口中定义与映射文件中id属性值相同的方法，MyBatis会自动去绑定和执行对应的SQL语句。这种接口实现方式，需要为每个Mapper创建一个接口，如果系统做大了，维护这些类会比较麻烦，大象个人倾向于基础服务式的Dao实现类.

	}	
}



[color=red][b]两种方式:[/b][/color]


[b]1.DAO方式,直接在dao里面调用xml的sql id.[/b]


IUsersDao.java


========================================


package com.dao;
import java.util.List;
public interface IUsersDao {
	public abstract List queryUsersByName(String name);
}




UsersDao.java


=================================


package com.dao.impl;
import java.util.List;
import org.mybatis.spring.support.SqlSessionDaoSupport;
import org.springframework.stereotype.Repository;
import com.dao.IUsersDao;
import com.pojo.Users;
@Repository
public class UsersDao extends SqlSessionDaoSupport implements IUsersDao{
	@Override
	public List queryUsersByName(String name){
		System.out.println("Users.queryUsersByName()");
		// com.mapper.IUsersMapper.queryUsersByName = (namespace+select/insert/update/delete)id
		return getSqlSession().selectList("com.mapper.IUsersMapper.queryUsersByName", name);
	}	
}



2.Mapper方式:A,实现类在实现接口的时候,直接封装和使用接口; b,接口的方法跟xml里面的sql id一定要一样.


IUsersMapper.java


=====================================


package com.mapper;
import com.pojo.Users;
public interface IUsersMapper {
	public abstract Users queryUsersById(int id);
	public abstract void insertUser(Users user);
	public abstract void updateUser(Users user);

}



UsersMapper.java


==================================


package com.mapper.impl;
import com.mapper.IUsersMapper;
import com.pojo.Users;
public class UsersMapper implements IUsersMapper {
	private IUsersMapper usersMapper;
	@Override
	public Users queryUsersById(int id) {
		return usersMapper.queryUsersById(id);
	}	
	@Override
	public void insertUser(Users user) {
		System.out.println("UsersMapper insertUser");
		usersMapper.insertUser(user);
	}	
	@Override
	public void updateUser(Users user) {
		System.out.println("UsersMapper updateUser");
		usersMapper.updateUser(user);
	}
	public IUsersMapper getUsersMapper() {
		return usersMapper;
	}
	public void setUsersMapper(IUsersMapper usersMapper) {
		this.usersMapper = usersMapper;
	}	
}


注意:


public class UsersMapper implements [color=red]IUsersMapper [/color]{

 private [color=red]IUsersMapper [/color]usersMapper;

}


[color=red][b]实现接口的同时,又使用它自己,并且这个方法名字又对应xml里面的ID[/b][/color].


service->mapper->DAO



[url]http://www.idashu.me/Mybatis-development.html[/url] 这里的说法又是不一样,不知道能否运行不(还没尝试)?


service->mapper, 它少了DAO,其实mapper就是DAO.


[color=red][b]注意文件的存放位置.[/b][/color]


[url]http://www.2cto.com/kf/201108/98937.html[/url]


[color=red]基于namespace接口与公用dao的区别[/color],从MyBatis3.0开始，对mapper中的namespace属性新增了一个特性：可以指定具体的接口来作为持久化操作类，在接口中定义与映射文件中id属性值相同的方法，MyBatis会自动去绑定和执行对应的SQL语句。这种接口实现方式，需要为每个Mapper创建一个接口，如果系统做大了，维护这些类会比较麻烦，大象个人倾向于基础服务式的Dao实现类.




[b]同时使用两种方式[/b]的例子:


IUsersService.java


=======================================================


package com.service;
import com.pojo.Users;
public interface IUsersService {
	public abstract Users queryUsersById(int id);
	public abstract Users queryUsersByName(String name);
	public abstract void saveUser(Users user);
}




UsersServiceImpl.java


=======================================================


package com.service.impl;
import java.util.List;
import javax.annotation.Resource;

import com.dao.IUsersDao;
import com.mapper.IUsersMapper;
import com.pojo.Users;
import com.service.IUsersService;

@Service(value="usersService")
@Transactional(rollbackFor=Exception.class)
public class UsersServiceImpl implements IUsersService {

	@Resource(name="usersMapper")
	private IUsersMapper usersMapper;

	@Resource(name="usersDao")
	private IUsersDao usersDao;

	@Override
	@Transactional(propagation=Propagation.REQUIRED, readOnly=true)
	public Users queryUsersById(int id){
		return usersMapper.queryUsersById(id);
	}

	@Override
	@Transactional(propagation=Propagation.REQUIRED, readOnly=true)
	public Users queryUsersByName(String name){
		List list = usersDao.queryUsersByName(name);
		System.out.println("list = "+list==null?"0":list.size());
		if(list!=null&&list.size()>0) return (Users)list.get(0);
		return null;
	}

	@Override
	@Transactional(propagation=Propagation.REQUIRED)
	public void saveUser(Users user){
		if(user.getId()<=0){
			System.out.println("insertUser");
			usersMapper.insertUser(user);
		}else{

			usersMapper.updateUser(user);
		}		
		//throw new RuntimeException("@@ Rollback for Debug..........");		
	}
}

import com.service.IUsersService;

@Controller
public class HelloController {	
	@Resource(name="usersService")
	private IUsersService usersService;

	@RequestMapping(value="sayHello")
	public ModelAndView sayHello(){
		ModelAndView view = new ModelAndView("sayHello");
		view.addObject("helloworld", "Hello World From Server.");		
		//insert
		Users user = new Users();
		user.setName("Pandy");
		user.setPassword("pandy");
		user.setEmail("[email protected]");
		user.setRemarks("nothing");

		usersService.saveUser(user);

		Users user1 = usersService.queryUsersByName(user.getName());
		//Users user1 = usersService.queryUsersById(0);
		if(user1!=null){
			System.out.println(user1.getName());
			view.addObject("userName", user1.getName());
		}else{
			System.out.println("Noting");
			view.addObject("userName", "Noting");
		}
		return view;
	}
