package com.jack.user.model.impl;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.jack.user.model.IUserServices;

public class ValidatorUser {
	private static Log log = LogFactory.getLog(ValidatorUser.class);
	private IUserServices userServices;
	public ValidatorUser(){
		ApplicationContext context = new ClassPathXmlApplicationContext("classpath:com/jack/user/config/servicesContext.xml");
		userServices = (IUserServices)context.getBean("userServices");
	}
	/**
	 * 检测用户名是否已经被注册。
	 * @param userName　用户名
	 * @return　返回用户是否已经被注册，True代表已经被注册，False代表未被注册
	 */
	public boolean checkUser(String userName){
		boolean result = false;
		log.debug("得到的用户名：" + userName);
		try{
			result = userServices.checkUserName(userName);
		}catch(Exception e){
			e.printStackTrace();
		}
		return result;
