UserService 接口：
package com.example.loginconnect.service;
import org.json.JSONObject;
public interface UserService {
public void userLogin(String loginName, String loginPassword)
throws Exception;
public void userResign(String loginName, String loginPassword,String surePassword,
String realName, String cellphone1, String cellphone2,
String cellphone3) throws Exception;
public JSONObject selectUser(String loginName, String realname,
String cellphone1, String cellphone2, String cellphone3)
throws Exception;
}
