SSM框架下实现登录注册的示例代码

基本配置：jdk1.8   tomcat 8  MyEclipse

先打好地基：

开始第一层啦：

pojo包：UserInfo 类

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层：（注意mybatis的xml文件也要放在mapper层）

ShopMapping.java:

其中@Param注解 是为了和xml中的查询参数进行绑定

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

PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"

"http://mybatis.org/dtd/mybatis-3-mapper.dtd">

select * from UserInfo where email=#{email} and password=#{password}

insert into UserInfo(name,email,password) values (#{name},#{email},#{password})

select count(*) from UserInfo where email=#{email}

service层：其实在写登陆的时候用了int类型，在想登陆也只要在数据库中查询表单输入的数据就行了，在mapper层的xml的文件中也写了 select count(*) 查询个数，  但是结果并不好，因为我要做的还有设置session。

package service;

import pojo.UserInfo;

public interface ShopService {

//用户注册

void regist(String name,String email,String password);

//用户登录

UserInfo login(String email,String password);

//验证

int findUser(String email);

}

service实现层：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层：

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("可以注册");

return "login";

} else {

// System.out.println("注册失败");

return "register";

}

}

@RequestMapping(value = "loginUser", method = RequestMethod.POST)

public String loginUser(UserInfo user, HttpSession session) {

// 调用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层当中，关于注册的格式要求还需要自行搜索一下，主要讲一下的是登陆。在登陆的这个方法中传递了两个形式参数，UserInfo是实体类，HttpSssion是设置session的关键，后面通过session.setAttribute()设置session，这也是在上文中提到的需要session的部分。在后来的注销中可以使用session.invalidate。
