SpringBoot实现QQ邮件发送

1. 建项目

   1. 创建一个SpringBoot项目

2. 改pom，导入相关依赖
   
   org.springframework.boot
   spring-boot-starter-parent
   2.2.2.RELEASE
   
   

   <dependencies>
       <!--web依赖-->
       <dependency>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-starter-web</artifactId>
       </dependency>
       <!--邮件发送依赖-->
       <dependency>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-starter-mail</artifactId>
       </dependency>
       <!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-test -->
       <dependency>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-starter-test</artifactId>
           <scope>test</scope>
       </dependency>
   </dependencies>
   

3. 写Yml，配置application.yml

   server:
   port: 端口号

   spring:
   mail:
   #邮件发送配置
   default-encoding: UTF-8
   host: smtp.qq.com
   # 授权码
   password: 你的授权码
   # 邮件发送安全配置
   properties:
   mail:
   smtp:
   auth: true
   starttls:
   enable: true
   required: true
   # 发件人信息
   username: 发件人邮箱

4. 主启动类EmailSignupApplication

   /**

   • @author QiuQiu&LL
   • @create 2021-08-09 2:18
   • @Description:
     */
     @SpringBootApplication
     @ComponentScan("com.qbb")
     public class EmailSignupApplication {
     public static void main(String[] args) {
     SpringApplication.run(EmailSignupApplication.class, args);
     }
     }

5. 业务

   1. 创建Service

   /**

   • @author QiuQiu&LL
   • @create 2021-08-09 2:18
   • @Description:
     /
     public interface MailService {
     /*
     • 发送邮件
     • @param to 邮件收件人
     • @param subject 邮件主题
     • @param verifyCode 邮件验证码
       */
       public void sendVertifyCode(String to, String subject, String verifyCode);
       }
   2. 实现类ServiceImpl

   package com.qbb.email_signup.service.impl;

   import com.qbb.email_signup.service.MailService;
   import org.slf4j.Logger;
   import org.slf4j.LoggerFactory;
   import org.springframework.beans.factory.annotation.Autowired;
   import org.springframework.beans.factory.annotation.Value;
   import org.springframework.mail.SimpleMailMessage;
   import org.springframework.mail.javamail.JavaMailSender;
   import org.springframework.stereotype.Service;

   /**

   • @author QiuQiu&LL

   • @create 2021-08-09 2:20

   • @Description:
     */
     @Service
     public class MailServiceImpl implements MailService {

     @Value("${spring.mail.username}")
     private String from;

     @Autowired
     private JavaMailSender mailSender;

     Logger logger = LoggerFactory.getLogger(this.getClass());

     /**

     • 发送邮件
     • @param to 邮件收件人
     • @param subject 邮件主题
     • @param verifyCode 邮件验证码
       */
       @Override
       public void sendVertifyCode(String to, String subject, String verifyCode) {
       SimpleMailMessage message = new SimpleMailMessage();
       message.setFrom(from); //发送人
       message.setTo(to); //收件人
       message.setSubject(subject); //邮件名
       message.setText(verifyCode); //邮件内容（验证码）
       mailSender.send(message);
       logger.info("已经发送");
       }
       }

6. 测试

   package com.qbb.email_signup;

   import com.qbb.email_signup.service.MailService;
   import org.junit.Test;
   import org.junit.runner.RunWith;
   import org.springframework.beans.factory.annotation.Autowired;
   import org.springframework.boot.test.context.SpringBootTest;
   import org.springframework.test.context.junit4.SpringRunner;

   /**

   • @author QiuQiu&LL

   • @create 2021-08-09 2:28

   • @Description:
     */
     @RunWith(SpringRunner.class)
     @SpringBootTest(classes = EmailSignupApplication.class)
     public class MailServiceTest {

     @Autowired
     private MailService mailService;

     @Test
     public void Test1() {
     /填你的测试信息/
     String to = "收件人邮箱";
     String title = "测试邮件";
     String context = "测试验证码";
     mailService.sendVertifyCode(to, title, context);
     }

   }
