Dao文件如下：

package com.edu.whu.sc.entityDao;

import java.util.List;

import com.edu.whu.sc.entity.Draginfo;

public interface DraginfoDao {
	void save(Draginfo draginfo);
	List<Draginfo> findSimilarByName(String name);
}

Dao文件实现如下：

package com.edu.whu.sc.entity;

import java.util.List;

import javax.annotation.Resource;

import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.stereotype.Component;

import com.edu.whu.sc.entityDao.DraginfoDao;
@Component("dragInfoImpl")
public class DraginfoImpl implements DraginfoDao{
	
	private SessionFactory sessionFactory;
	public DraginfoImpl() {
		// TODO Auto-generated constructor stub
	}

	public void save(Draginfo draginfo){
		Session session = sessionFactory.getCurrentSession();
//		session.getTransaction().begin();
		session.save(draginfo);
//		session.getTransaction().commit();
	}
	
	public List<Draginfo> findSimilarByName(String name){
		Session session = sessionFactory.getCurrentSession();
		Query query = session.createQuery("from draginfo di where di.name like '%:name%'").setString("name", name);
		List<Draginfo> resultList = query.list();
		
		return resultList;
	}
	
	public SessionFactory getSessionFactory(){
		return this.sessionFactory;
	}
	
	@Resource(name = "sessionFactory")
	public void setSessionFactory (SessionFactory sessionFactory){
		this.sessionFactory = sessionFactory;
	}
}

service文件如下：

package com.edu.whu.sc.service;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Component;

import com.edu.whu.sc.daoimpl.DraginfoImpl;
import com.edu.whu.sc.entity.Draginfo;
import com.edu.whu.sc.entityDao.DraginfoDao;
import com.edu.whu.sc.serviceDao.DraginfoServiceDao;
@Component("dragService")
public class DragService implements DraginfoServiceDao{

	private DraginfoDao draginfoImpl;
	public DragService() {
		// TODO Auto-generated constructor stub
	}
	public DraginfoDao getDraginfoImpl() {
		return draginfoImpl;
	}
	
	@Resource(name="dragInfoImpl")
	public void setDraginfoImpl(DraginfoImpl draginfoImpl) {
		//此处改为DraginfoDao
		this.draginfoImpl = draginfoImpl;
	}
	
	public List<Draginfo> findSimilarByName(String name) {
		return draginfoImpl.findSimilarByName(name);
	}
	
}
