看了心血来潮,我要是实现springboot的验证码接口发送,网上一搜,就找到不少教程
笔者的邮箱是126,配置的时候要开ssl

简易邮件发送,到接口邮件发送

简易的发送邮件方法就只需要简易的配置

spring.mail.username=scwelcome@126.com  
spring.mail.password=HOYROCEIIGJDFOAP  
spring.mail.host=smtp.126.com

然后自己就是随便写一个测试类或者main

@SpringBootTest  class DemoApplicationTests {  
    @Autowired  JavaMailSenderImpl mailSender;  
    @Test  void contextLoads() {  
        SimpleMailMessage message = new SimpleMailMessage();  
        message.setTo("runformoon@foxmail.com");  
        message.setFrom("scwelcome@126.com");  
        message.setSubject("你好哇!!!");  
        message.setText("57236+54345=?");  
        mailSender.send(message);  
    }  
}

首先加入springBoot依赖

  
   org.springframework.boot  
   spring-boot-starter-mail  

加好之后,在配置文件application.properties加配置

#发件人邮箱服务器相关配置  
spring.mail.host=smtp.126.com  
spring.mail.port=465  
#spring.mail.port=587  
#配置个人QQ账号和密码(密码是加密后的授权码)  
spring.mail.username=###你的126邮箱###  
spring.mail.password=###你的授权码###  
spring.mail.default-encoding=utf-8  
  
  
# SSL 配置  
spring.mail.protocol=smtp  
spring.mail.properties.mail.smtp.ssl.enable=true  
spring.mail.properties.mail.smtp.socketFactory.port=465  
spring.mail.properties.mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory

要写接口那就要加上上面的ssl
并且写controller层EmailController.java(自己导包)

@RestController  
public class EmailController {  
   @Autowired  
   EmailService emailService= new EmailService() ;  
    @GetMapping("/name/{to}/code/{sub}")  
   public String sendSimpleEmail(@PathVariable("to") String to,@PathVariable("sub") String sub) {  
      String subject="阿狸科技的验证码是" + sub ;  
      String text="Hello World";  
      emailService.sendSimpleEmail(to, subject, text);  
      return "邮件发送成功";  
   }  
      
  
}

service层@Service.java (自己导包)

@Service
public class EmailService {
	@Autowired  
private JavaMailSenderImpl mailSender;  
 @Value("${spring.mail.username}")  
private String from;  
 //纯文本邮件信息发送  
 public void sendSimpleEmail(String to,String subject,String text) {  
    //定制纯文本邮件信息SimpleMailMessage  
    SimpleMailMessage message=new SimpleMailMessage();  
    message.setFrom(from);  
    message.setTo(to);  
    message.setSubject(subject);  
    message.setText(text);  
    mailSender.send(message);  
 }
}

ok算是大功告成了

浏览器输入
localhost:8080/name/###你的邮箱###/code/##验证码##
发送成功
