springboot邮箱注册

1.准备工作

操作之前准备两个邮箱

我准备了网易邮箱和QQ邮箱，网易邮箱用来发送验证码，QQ邮箱用来做注册（希望大家和我一样，不然可能会出错）

发送验证码的邮箱需要开启一些设置，否则不能发送验证码

网易免费邮箱 - 你的专业电子邮局

网易邮箱官网，没有的注册一个，有的直接输入账号密码登录，

1.登录后点击设置

2.继续操作

3.保证两个服务开启:

IMAP/SMTP服务:
POP3/SMTP服务:

4.生成授权码（授权码要保存起来，只能查看一次，）

将生成的授权码放入properties配置文件（稍后会用）

server.port=8081
restart.include.mapper=/mapper-[\\w-\\.]+jar
restart.include.pagehelper=/pagehelper-[\\w-\\.]+jar
spring.mvc.static-path-pattern=/static/**
spring.thymeleaf.prefix=classpath:/templates/
spring.thymeleaf.suffix=.html
spring.thymeleaf.mode=HTML5
spring.thymeleaf.encoding=UTF-8
spring.thymeleaf.servlet.content-type=text/html
spring.thymeleaf.cache=false
spring.datasource.url=jdbc:mysql://localhost:3306/test?useSSL=false
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.druid.initial-size=1
spring.datasource.druid.min-idle=1
spring.datasource.druid.max-active=20
spring.datasource.druid.test-on-borrow=true
spring.datasource.druid.stat-view-servlet.allow=true
mybatis.type-aliases-package=com.dss.springboot.entity
mybatis.mapper-locations=classpath:mapper/**/*.xml
spring.mail.default-encoding=utf-8
spring.mail.host=smtp.163.com
spring.mail.username=15543326163@163.com
spring.mail.password=
spring.mail.protocol=smtp
spring.mail.port=25

根据配置文件修改成自己的数据库和密码

发送消息的账号添加到

spring.mail.username=xxxxxx@163.com

其他设计默认即可

4.创建数据库

5.新建数据库

6.用户表语句：

user表数据库建表语句：

create table user
(uid      int auto_incrementprimary key,username varchar(255) not null,password varchar(255) not null,nickname varchar(255) null,email    varchar(255) not null,state    int          not null,code     varchar(255) null
);

在控制台执行

2.开始搭建：

选择有项目 sdk 8+java8 没有的随便选等创建项目完成在修改

将文件复制到properties

1.properties

server.port=8081
restart.include.mapper=/mapper-[\\w-\\.]+jar
restart.include.pagehelper=/pagehelper-[\\w-\\.]+jar
spring.mvc.static-path-pattern=/static/**
spring.thymeleaf.prefix=classpath:/templates/
spring.thymeleaf.suffix=.html
spring.thymeleaf.mode=HTML5
spring.thymeleaf.encoding=UTF-8
spring.thymeleaf.servlet.content-type=text/html
spring.thymeleaf.cache=false
spring.datasource.url=jdbc:mysql://localhost:3306/test?useSSL=false
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.druid.initial-size=1
spring.datasource.druid.min-idle=1
spring.datasource.druid.max-active=20spring.datasource.druid.test-on-borrow=true
spring.datasource.druid.stat-view-servlet.allow=true
mybatis.type-aliases-package=com.dss.springboot.entity
mybatis.mapper-locations=classpath:mapper/**/*.xml
spring.mail.default-encoding=utf-8
spring.mail.host=smtp.163.com
spring.mail.username=15543326163@163.com
spring.mail.password=你邮箱生成的授权码 
spring.mail.protocol=smtp
spring.mail.port=25

2. pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.dss</groupId><artifactId>springboot--javaMail</artifactId><version>0.0.1-SNAPSHOT</version><packaging>war</packaging><name>emailtest</name><description>Demo project for Spring Boot</description><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.0.3.RELEASE</version><relativePath /> <!-- lookup parent from repository --></parent><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding><java.version>1.8</java.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-tomcat</artifactId><scope>provided</scope></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><!-- 引入 thymeleaf 模板依赖 --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-thymeleaf</artifactId></dependency><!-- 引入数据源依赖，这里使用alibaba的druid数据源 --><dependency><groupId>com.alibaba</groupId><artifactId>druid</artifactId><version>1.1.0</version></dependency><!-- mysql的连接依赖 --><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>8.0.32</version></dependency><!--mybatis相关依赖 --><dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>1.3.1</version></dependency><!-- 支持发送邮件 --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-mail</artifactId></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>

3.连接数据库

4.修改文件设置，

5. 启动项目（检验配置是否成功）

6. 配置注册页面

resource目录下templates 下新建 thymeleaf 文件夹新建页面

register.html

<!DOCTYPE html>
<html>
<head lang="en"><meta charset="UTF-8" /><title></title>
</head>
<body><form action="/user/register" method="post">用户名：<input type="text" name="username" id="username"/><br/>密码：<input type="password" name="password" id="password"/><br/>确认密码：<input type="password" name="password1" id="password1"/><br/>昵称:<input type="text" name="nickname" id="nickname"/><br/>邮箱：<input type="text" name="email" id="email"/><br/><input type="submit" value="注册"/>
</form></body>
</html>

result.html

<!DOCTYPE html>
<html>
<head lang="en"><meta charset="UTF-8" /><title></title>
</head>
<body><h1 th:text="${message}"></h1></body>
</html>

7. 用mybatisx

生成实体类 mapper 层 service 层 imp层 mapper.xml

整理后项目结够如下

8.添加工具类

package com.dss.javaMail.utils;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.stereotype.Component;/*** 发送邮件的工具类* @author duan ss**/
@Component
public class MailUtil {@Autowiredprivate JavaMailSender javaMailSender;/*** 发送邮件* @param toUser	收件人* @param code		激活码* @return*/public String send(String toUser, String code) {// 建立邮件消息SimpleMailMessage mainMessage = new SimpleMailMessage();// 发送者mainMessage.setFrom("15543326163@163.com");// 接收者mainMessage.setTo(toUser);// 发送的标题mainMessage.setSubject("注册激活邮件");// 发送的内容mainMessage.setText("<h1>来自xxx网站的注册激活邮件，激活请点击以下链接：http://localhost:8081/user/regActive?code="+code+"");javaMailSender.send(mainMessage);return "success";}}

9.编写各层代码

mapper层

package com.example.emailtest.mapper;import com.example.emailtest.domain.User;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import org.apache.ibatis.annotations.Mapper;/**
* @author l
* @description 针对表【user】的数据库操作Mapper
* @createDate 2024-02-23 12:49:21
* @Entity com.example.emailtest.domain.User
*/
@Mapper
public interface UserMapper extends BaseMapper<User> {void registerUser(User user);User getUserByCode(User user);void updateState(User user);User getUserByUsernameAndPassword(String username, String password);
}

service层

package com.example.emailtest.service;import com.example.emailtest.domain.User;
import com.baomidou.mybatisplus.extension.service.IService;/**
* @author l
* @description 针对表【user】的数据库操作Service
* @createDate 2024-02-23 12:49:21
*/
public interface UserService extends IService<User> {void registerUser(User user);User getUserByCode(User user);void updateState(User user);User getUserByUsernameAndPassword(String username, String password);
}

serviceimpl层

package com.example.emailtest.service.impl;import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.example.emailtest.domain.User;
import com.example.emailtest.service.UserService;
import com.example.emailtest.mapper.UserMapper;
import org.springframework.stereotype.Service;import javax.annotation.Resource;/**
* @author l
* @description 针对表【user】的数据库操作Service实现
* @createDate 2024-02-23 12:49:21
*/
@Service
public class UserServiceImpl extends ServiceImpl<UserMapper, User>implements UserService {@Resourceprivate UserMapper userMapper;@Overridepublic void registerUser(User user) {userMapper.registerUser(user);}@Overridepublic User getUserByCode(User user) {return userMapper.getUserByCode(user);}@Overridepublic void updateState(User user) {userMapper.updateState(user);}@Overridepublic User getUserByUsernameAndPassword(String username, String password) {return userMapper.getUserByUsernameAndPassword(username, password);}
}

mapper.xml层

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapperPUBLIC "-//mybatis.org//DTD Mapper 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.example.emailtest.mapper.UserMapper"><resultMap id="BaseResultMap" type="com.example.emailtest.domain.User"><id property="uid" column="uid" jdbcType="INTEGER"/><result property="username" column="username" jdbcType="VARCHAR"/><result property="password" column="password" jdbcType="VARCHAR"/><result property="nickname" column="nickname" jdbcType="VARCHAR"/><result property="email" column="email" jdbcType="VARCHAR"/><result property="state" column="state" jdbcType="INTEGER"/><result property="code" column="code" jdbcType="VARCHAR"/></resultMap><sql id="Base_Column_List">uid,username,password,nickname,email,state,code</sql><insert id="registerUser" parameterType="com.example.emailtest.domain.User">insert into user values(#{ uid}, #{username}, #{password}, #{nickname}, #{email}, #{state}, #{code})</insert><update id="updateState">update user set state = 1 where uid = #{uid} and code = #{code}</update><select id="getUserByCode" resultType="com.example.emailtest.domain.User">select * from user where code = #{code}</select><select id="getUserByUsernameAndPassword" resultType="com.example.emailtest.domain.User">
select * from user where username = #{username} and password = #{password}</select>
</mapper>

controller层

package com.example.emailtest.controller;import com.example.emailtest.domain.User;
import com.example.emailtest.mapper.UserMapper;
import com.example.emailtest.service.UserService;
import com.example.emailtest.utils.MailUtil;
import com.example.emailtest.utils.UuidUtil;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.*;import javax.annotation.Resource;@Controller
@RequestMapping(value = "/user")
public class UserController {@ResourceUserMapper userMapper;@Autowiredprivate UserService userService;@Autowiredprivate MailUtil mailUtil;@RequestMapping(value = "/goReg")public String getUser() {return "thymeleaf/register";}@RequestMapping(value = "/register")@ResponseBodypublic String register(User user) {user.setState(0);		//	0表示未激活/1表示激活user.setCode(UuidUtil.get32UUID());String result = mailUtil.send(user.getEmail(), user.getCode());System.out.println("发送邮件结果： " + result);System.out.println(user);userService.registerUser(user);return "success";}@RequestMapping(value = "/regActive")public String regActive(@RequestParam("code") String code,ModelMap map) {User user = new User();user.setCode(code);user = userService.getUserByCode(user);if(user != null) {if(user.getState() == 1) {map.addAttribute("message", "你已经激活过了...");}else {userService.updateState(user);map.addAttribute("message", "激活成功...");}}else {map.addAttribute("message", "激活失败...");}return "thymeleaf/result";}}

启动类加mappscan注解！！！！！！！！！！！！！！！

package com.example.emailtest;import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@MapperScan("com.example.emailtest.mapper")
@SpringBootApplication
public class EmailtestApplication {public static void main(String[] args) {SpringApplication.run(EmailtestApplication.class, args);}}
