usermanager.java

笔者试图用最简单易懂的应用为初学者演示spring DAO

package com.ligx.Manager;

import java.util.*;

import com.ligx.Model.*;
import com.ligx.DAO.*;

public class UserManager {
	List list = new ArrayList();
	UserModel model = new UserModel();
	UserDao dao = new UserDao();
	
	public void getConn()
	{
		try{
			dao.openConn();
		}
		catch(Exception e)
		{
			System.out.println(e.toString());
		}
	}
	public void closeConn()
	{
		try{
			dao.closeConn();
		}
		catch(Exception e)
		{
			System.out.println(e.toString());
		}	
	}
	public List query(String sql)
	{
		list = dao.query(sql);
		return list;
	}
}
