開始第一層啦：

pojo包：UserInfo 類

package pojo;

public class UserInfo {
		private String uid;
		private String name;
		private String email;
		private String password;
		public String getUid() {
			return uid;
		}
		public void setUid(String uid) {
			this.uid = uid;
		}
		public String getName() {
			return name;
		}
		public void setName(String name) {
			this.name = name;
		}
		public String getEmail() {
			return email;
		}
		public void setEmail(String email) {
			this.email = email;
		}
		public String getPassword() {
			return password;
		}
		public void setPassword(String password) {
			this.password = password;
		}
		@Override
		public String toString() {
			return "UserInfo [uid=" + uid + ", name=" + name + ", email="
					+ email + ", password=" + password + "]";
		}
		
		
		
}

mapper層：（注意mybatis的xml檔案也要放在mapper層）

ShopMapping.java:

其中@Param註解 是為了和xml中的查詢引數進行繫結

package mapper;


import org.apache.ibatis.annotations.Param;
import pojo.UserInfo;
public interface ShopMapper {
		public void register(@Param("name")String name,@Param("email")String email,@Param("password")String password);
		 public UserInfo login(@Param("email")String email,@Param("password")String password);  
		 public int findUser(@Param("email")String email);
		
}

Shop.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper
    PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
    "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
    <mapper namespace="mapper.ShopMapper">
    <select id="login" resultType="UserInfo" parameterType="String" >
    select * from UserInfo where email=#{email} and password=#{password}
    </select>
    
    <select id="register" resultType="UserInfo">
    insert into UserInfo(name,email,password) values (#{name},#{email},#{password})
    </select>
    
    <select id="findUser" resultType="int">
    select count(*) from UserInfo where email=#{email}
    </select>
    
    </mapper>

service層：其實在寫登陸的時候用了int型別，在想登陸也只要在資料庫中查詢表單輸入的資料就行了，在mapper層的xml的檔案中也寫了 select count(*) 查詢個數，但是結果並不好，因為我要做的還有設定session。

package service;

import pojo.UserInfo;

public interface ShopService {
		//使用者註冊
		void regist(String name,String email,String password);
		//使用者登入
		UserInfo login(String  email,String password);
		//驗證
		int findUser(String email);

}

service實現層：service.Impl

package service.Impl;

import mapper.ShopMapper;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import pojo.UserInfo;
import service.ShopService;

@Service
public class ShopServiceImpl implements ShopService {
	@Autowired
	public ShopMapper sm;

	@Override
	public void regist(String name, String email, String password) {
		 sm.register(name, email, password);
	}

	@Override
	public UserInfo login(String email, String password) {
		UserInfo user=sm.login(email, password);
		if(user!=null &&user.getPassword().equals(password)){
			return user;
		}
		return null;
		
	}

	@Override
	public int findUser(String email) {
		if(sm.findUser(email)==0){
			return 0;
		}
		return 1;
	}


	

	

	
}

controller層：

package controller;

import javax.servlet.http.HttpSession;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import pojo.UserInfo;
import service.ShopService;

@Controller
@RequestMapping("")
public class ShopController {
	@Autowired
	public ShopService ss;

	@RequestMapping(value = "registerUser", method = RequestMethod.POST)
	public String registerUser(String name, String email, String password) {
		int findUser = ss.findUser(email);

		if (findUser == 0) {
			ss.regist(name, email, password);
			// System.out.println("可以註冊");
			return "login";
		} else {
			// System.out.println("註冊失敗");
			return "register";
		}
	}

	@RequestMapping(value = "loginUser", method = RequestMethod.POST)
	public String loginUser(UserInfo user, HttpSession session) {
		// 呼叫service方法
		user = ss.login(user.getEmail(), user.getPassword());

		if (user != null) {
			session.setAttribute("u".user);
			return "index";
		}
		return "login";

	}
	
	@RequestMapping("/outLogin")
	public String outLogin(HttpSession session){
		session.invalidate();
		return "index";
		
	}
}

在controller層當中，關於註冊的格式要求還需要自行搜尋一下，主要講一下的是登陸。在登陸的這個方法中傳遞了兩個形式引數，UserInfo是實體類，HttpSssion是設定session的關鍵，後面通過session.setAttribute()設定session，這也是在上文中提到的需要session的部分。在後來的登出中可以使用session.invalidate。

第一次寫文，文章漏洞百出，還望各位指正，一起學習。
