java邮件案例

  1. 引入依赖

    <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-mail</artifactId>
            <version>2.2.6.RELEASE</version>
        </dependency>

  2. 配置邮件参数

    spring:
  mail:
    host: smtp.qq.com
    username: 1497315494@qq.com
    password: omoouhbxawdpbaef
    default-encoding: UTF-8
    properties:
      mail:
        smtp:
          socketFactory:
            class: javax.net.ssl.SSLSocketFactory
            port: 465
          auth: true
          starttls:
            enable: true
            required: true

  3. 创建线程池

    @Bean
    public ThreadPoolTaskExecutor createThreadPoolTaskExecutor(){
        ThreadPoolTaskExecutor threadPoolTaskExecutor = new ThreadPoolTaskExecutor();
        threadPoolTaskExecutor.setCorePoolSize(5);
        threadPoolTaskExecutor.setMaxPoolSize(10);
        return threadPoolTaskExecutor;
    }

  4. 创建发邮件放方法

    private final Logger logger= LoggerFactory.getLogger(this.getClass());
    @Autowired
    private JavaMailSender javaMailSender;
    @Value("${spring.mail.username}")
    private String from;
    public  void sendMail(String recipient,String subject,String content){
        try {
            SimpleMailMessage simpleMailMessage=new SimpleMailMessage();
            simpleMailMessage.setFrom(from);
            simpleMailMessage.setTo(recipient);
            simpleMailMessage.setSubject(subject);
            simpleMailMessage.setText(content);
            simpleMailMessage.setSentDate(new Date());
            javaMailSender.send(simpleMailMessage);
            logger.info("发送成功");
        }catch (Exception e){
            logger.info("错误信息"+e);
        }
    }

  5. 测试

    @Autowired
    SendMail sendMail;
    @Autowired
    ThreadPoolTaskExecutor threadPoolTaskExecutor;

    @Test
    void contextLoads() {
        threadPoolTaskExecutor.execute(new Runnable() {
            @Override
            public void run() {
                sendMail.sendMail("1497315494@qq.com","test","hello world");
            }
        });
        try {
            Thread.sleep(5000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }          
    }
