operatorservice.java

是我自己在做java训练的时候做的一个小项目

package com.magic.mobile.service;

import com.magic.mobile.dao.OperatorDAO;
import com.magic.mobile.dao.impl.OperatorDAOImpl;
import com.magic.mobile.exception.PasswordNotMatchException;
import com.magic.mobile.exception.UserNotFoundException;
import com.magic.mobile.vo.Operator;

public class OperatorService {
    private  static OperatorService os= new OperatorService();
    private OperatorDAO od= null;
  //  private OperatorDAOImpl odi=null;
    private OperatorService(){
    	
    }
    public void setOperator(OperatorDAO od){
    	this.od=od;
    }
    
    public static OperatorService getInstance(){
      os.setOperator(new OperatorDAOImpl());
    	return os;
    }
    
	public Operator validate(String operator_Id, String operatorPwd)
	throws UserNotFoundException, PasswordNotMatchException{
         return od.validate(operator_Id, operatorPwd);
	}
    
	
}
