验证登陆时无法获取数据表信息

# 具体遇到的问题
通过executeQuery获取后resultSet为空

package dao.impl;

import java.sql.Connection;

import java.sql.PreparedStatement;

import java.sql.ResultSet;

import dao.UserDao;

import domain.user;

import utils.JDBCUtils;

public class UserDaoImpl implements UserDao {

@Override

public user verify(user user1) {

// TODO Auto-generated method stub

Connection conn=null;

PreparedStatement pstmt=null;

ResultSet rs=null;

try {

conn=JDBCUtils.getConnection();

String sql="select * from user where username=? and password=?";

pstmt=conn.prepareStatement(sql);

pstmt.setString(1, user1.getName());

pstmt.setString(2, user1.getPassword());

rs=pstmt.executeQuery();

System.out.println("找到1");

if(rs.next()) {

System.out.println("找到2");

user user2=new user();

user2.setId(rs.getInt("id"));

user2.setName(rs.getString("username"));

user2.setPassword(rs.getString("password"));

return user2;

}

}catch(Exception e) {

e.printStackTrace();

}finally {

JDBCUtils.release(rs, pstmt, conn);

}

return null;

}

}
