UserDao

package com.zhongruan.dao;

import com.zhongruan.bean.UserInfo;

import java.util.List;

public interface UserDao {

    public List findAll();

    public UserInfo doLogin (UserInfo userInfo);
}

UserServiceImpl

package com.zhongruan.service.impl;

import com.zhongruan.bean.UserInfo;
import com.zhongruan.dao.UserDao;
import com.zhongruan.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class UserServiceImpl implements UserService {

    @Autowired
    private UserDao userDao;
    @Override
    public List findAll() {
        return userDao.findAll();
    }

    @Override
    public Boolean doLogin(UserInfo userInfo) {
        UserInfo userInfo1=userDao.doLogin(userInfo);
        if(null!=userInfo1)
        {
            return true;
        }
        else{
            return false;
        }
    }
}

UserService

package com.zhongruan.service;

import com.zhongruan.bean.UserInfo;

import java.util.List;

public interface UserService {
    public List findAll();

    public Boolean doLogin (UserInfo userInfo);

}

其余部分与我之前所发增删改查的配置情况基本相同，只有这几处改动较大

结果
