(五)SpringBoot 配置郵件Mail

1. 添加依賴

<!-- mail依賴 -->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-mail</artifactId>
		</dependency>

2.yml文件添加mail配置

 mail:
    host: 
    username: 
    password: 
    default-encoding: utf-8

3.

@Service
public class MailServiceImpl implements MailService {
    @Value("${spring.mail.username}")
    private String from;

    @Autowired
    private JavaMailSender sender;

    /**
     * @Description //TODO 發送簡單郵件
    
     * @return void
     **/
    public void sendEmail(String[] to, String title, String content){
        SimpleMailMessage message = new SimpleMailMessage();
        message.setFrom(from); //發送者
        message.setTo(to); //接受者
        message.setSubject(title); //發送標題
        message.setText(content);  //發送內容
        //sender.send(message);

    }
    /**
     * @Description //TODO 發送html格式內容的郵件
     * 
     * @return void
     **/
    @Async //異步調用這個方法
    public void sendInlineMail(String[] to, String title, String content) throws Exception {
        MimeMessage mimeMessage = sender.createMimeMessage();
        MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true);
        helper.setFrom(from);
        helper.setTo(to);
        helper.setSubject(title);
        helper.setText(content, true); //注意:調用setText時需要在第二個參數傳入true，這樣纔會使用HTML格式發送郵件
        sender.send(mimeMessage);
    }
    
    
}

如果使用@Async //異步調用這個方法異步；在啓動類添加註解：@EnableAsync
