学习了些皮毛，尝试练习，大佬见笑啦。

准备工作，添加 application.properties的设置：

// 数据库设置
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url= jdbc:mysql://localhost:3306/mynote
spring.datasource.username= root
spring.datasource.password= 123456

// 自动化驼峰命名映射
mybatis.configuration.map-underscore-to-camel-case=true

// 控制台输出 mybatis 日志
mybatis.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl

1、用户数据

CREATE DATABASE mynote;
USE mynote;
CREATE TABLE USER(
    user_name VARCHAR(255) NOT NULL,
    user_email VARCHAR(255) NOT NULL,
    password VARCHAR(255) NOT NULL,
    create_time DATETIME NOT NULL,
    update_time DATETIME NOT NULL,
    last_login_time DATETIME
);

2、创建实体类

UserEntity：

package com.angindem.Entity;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import java.time.LocalDateTime;
@Data
@NoArgsConstructor
@AllArgsConstructor
public class UserEntity {
    private String userName;
    private String userEmaile;
    private String password;
    private LocalDateTime createTime;
    private LocalDateTime updateTime;
    private LocalDateTime lasterLoginTime;
}

ResultEntity:

package com.angindem.Entity;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@NoArgsConstructor
@AllArgsConstructor
public class ResultEntity {
    private Integer code;
    private String msg;
    private Object data;

    public ResultEntity(Integer code, String msg) {
        this.code = code;
        this.msg = msg;
    }

    public static ResultEntity succeed() {
        return new ResultEntity(200, "操作成功！！！");
    }

    public static ResultEntity succeed(String msg) {
        return new ResultEntity(200, msg);
    }

    public static ResultEntity succeed(String msg, Object data) {
        return new ResultEntity(200, msg, data);
    }

    public static ResultEntity error() {
        return new ResultEntity(500, "操作失败！！！");
    }

    public static ResultEntity error(String msg) {
        return new ResultEntity(500, msg);
    }
}

3、创建 Controller、Service、Mapper

UserController：

package com.angindem.Controller;

import com.angindem.Entity.ResultEntity;
import com.angindem.Entity.UserEntity;
import com.angindem.Service.UserService;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.time.LocalDateTime;

@Slf4j
@RestController
@RequestMapping("/mynote")
public class UserController {

    @Autowired
    private UserService userService;

    @PostMapping("/register")
    public ResultEntity register(@RequestBody UserEntity user)
    {
        user.setCreateTime(LocalDateTime.now());
        user.setUpdateTime(LocalDateTime.now());
        log.info("注册服务：{}",user);
        userService.register(user);
        return ResultEntity.succeed();
    }
}

UserService:

package com.angindem.Service;

import com.angindem.Entity.UserEntity;

public interface UserService {
    void register(UserEntity user);
}

UserServiceImpl:

package com.angindem.Service.Impl;

import com.angindem.Entity.UserEntity;
import com.angindem.Mapper.UserMapper;
import com.angindem.Service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class UserServiceImpl implements UserService {

    @Autowired
    private UserMapper userMapper;

    @Override
    public void register(UserEntity user) {
        userMapper.insert(user);
    }
}

UserMapper:

package com.angindem.Mapper;

import com.angindem.Entity.UserEntity;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Mapper;

@Mapper
public interface UserMapper {

    @Insert("insert into user(user_name, user_email, password, create_time, update_time) " +
            "values(#{userName},#{userEmaile},#{password},#{createTime},#{updateTime}) ")
    void insert(UserEntity user);
}

4、APIfox测试是否添加成功：

成功插入数据！！！

5、引入发送与接收邮箱功能

进入QQ邮箱开启邮箱服务获取授权码：

PS：这里我已经开启过了，未开启的根据官方提示开启即可，开启后进入管理服务

引入邮箱依赖：

<!--邮箱依赖-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-mail</artifactId>
</dependency>

添加 application.properties 的设置：

# 配置邮箱用户名
spring.mail.username=你的QQ邮箱号码
# 配置申请到的授权码  
spring.mail.password=刚才短信申请到的授权码
# 配置 smtp 服务器地址
spring.mail.host=smtp.qq.com
# 启用 SSL 连接
spring.mail.properties.mail.smtp.ssl.enable=true
# 配置邮件编码
spring.mail.default-encoding=UTF-8

测试发送Tesst类：

package com.angindem;

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSenderImpl;

import java.util.Date;

@SpringBootTest
class MyProjectApplicationTests {

    @Autowired
    private JavaMailSenderImpl javaMailSender;
    @Test
    public void TestSendQQemail()
    {
        //一个简单的邮件发送
        SimpleMailMessage mailMessage = new SimpleMailMessage(); //创建一个邮件信息
        mailMessage.setSentDate(new Date());
        mailMessage.setSubject("TestSend");                        //邮件的主题
        mailMessage.setText("新学习的Spring Boot邮件发送的知识");          //邮件的内容
        mailMessage.setTo("**********@qq.com");                        //发送者的邮箱
        mailMessage.setFrom("**********@qq.com");                      //接收者的邮箱
        //我这里发送者和接收者都填写的是自己的邮箱
        javaMailSender.send(mailMessage);                                //发送邮件
    }


}
