SpringBoot 整合 E-mail傳送郵件

JDK本身有自帶傳送郵件api，加上SpringBoot在進行封裝，使得現在使用起來十分快速簡潔。
話不多說，參考純潔的微笑部落格，更改jar版本為2.0.4 開幹，基本沒什麼坑。
就是配置郵箱賬號密碼是，如果是qq郵箱，需要開啟PO30和STMP服務,並且獲取臨時授權碼。
開啟服務連結：

與Springboot整合

匯入jar包

compile group: 'org.springframework.boot', name: 'spring-boot-starter-mail', version: '2.0.4.RELEASE'
compile 'org.springframework.boot:spring-boot-starter-thymeleaf:2.0.4.RELEASE'
 

配置郵箱

#郵箱伺服器地址，各大運營商不同
spring.mail.host=smtp.qq.com
#使用者名稱
[email protected]
#密碼，如果是qq的，要申請臨時授權碼
spring.mail.password=faw124awfawfawg
spring.mail.default-encoding=UTF-8
#以誰來發送郵件
[email protected]

傳送各種型別的郵件

@Service
@Slf4j
public class MailServiceImpl implements MailService {
    @Autowired
 

    private JavaMailSender mailSender;
    /**
     * The Template engine.
     */
    @Autowired
    TemplateEngine templateEngine;
    @Value("${mail.fromMail.addr}")
    private String from;

    @Override
    public void sendSimpleMail(String to, String subject, String content) {
        SimpleMailMessage message =
 
 new SimpleMailMessage();
        message.setFrom(from);
        message.setTo(to);
        message.setSubject(subject);
        message.setText(content);

        try {
            mailSender.send(message);
            log.info("簡單郵件已經發送。");
        } catch (Exception e) {
            log.error("傳送簡單郵件時發生異常！", e);
        }
    }

    @Override
    public void sendHtmlMail(String to, String subject, String content) {
        MimeMessage message = mailSender.createMimeMessage();

        try {
            //true表示需要建立一個multipart message
            MimeMessageHelper helper = new MimeMessageHelper(message, true);
            helper.setFrom(from);
            helper.setTo(to);
            helper.setSubject(subject);
            helper.setText(content, true);
            mailSender.send(message);
            log.info("html郵件傳送成功");
        } catch (MessagingException e) {
            log.error("傳送html郵件時發生異常！", e);
        }
    }

    @Override
    public void sendAttachmentsMail(String to, String subject, String content, String filePath) {
        MimeMessage message = mailSender.createMimeMessage();
        try {
            MimeMessageHelper helper = new MimeMessageHelper(message, true);
            helper.setFrom(from);
            helper.setTo(to);
            helper.setSubject(subject);
            helper.setText(content, true);
            FileSystemResource file = new FileSystemResource(new File(filePath));
            String fileName = filePath.substring(filePath.lastIndexOf(File.separator) + 1);
            helper.addAttachment(fileName, file);

            mailSender.send(message);
            log.info("帶附件的郵件已經發送。");
        } catch (MessagingException e) {
            log.error("傳送帶附件的郵件時發生異常！", e);
        }
    }

    @Override
    public void sendInlineResourceMail(String to, String subject, String content, String rscPath, String rscId) {
        MimeMessage message = mailSender.createMimeMessage();
        try {
            MimeMessageHelper helper = new MimeMessageHelper(message, true);
            helper.setFrom(from);
            helper.setTo(to);
            helper.setSubject(subject);
            helper.setText(content, true);

            FileSystemResource res = new FileSystemResource(new File(rscPath));
            helper.addInline(rscId, res);

            mailSender.send(message);
            log.info("嵌入靜態資源的郵件已經發送。");
        } catch (MessagingException e) {
            log.error("傳送嵌入靜態資源的郵件時發生異常！", e);
        }
    }

    @Override
    public void sendTemplateMail(String to, String subject, String template, Context context) {
        String emailContent = templateEngine.process(template, context);
        sendHtmlMail("[email protected]", "主題：這是模板郵件", emailContent);
    }
}

測試類：

@RunWith(SpringRunner.class)
@SpringBootTest
public class EmailServiceTest {
    @Autowired
    MailService mailService;

    @Test
    public void sendSimpleMailTest() {
        mailService.sendSimpleMail("[email protected]","test simple mail"," hello this is simple mail");
    }

    @Test
    public void sendHtmlMailTest(){
        String content="<html>\n" +
                "<body>\n" +
                "    <h3>hello world ! 這是一封Html郵件!</h3>\n" +
                "</body>\n" +
                "</html>";
        mailService.sendHtmlMail("[email protected]","test html mail",content);
    }

    @Test
    public void sendAttachmentsMail(){
        String filePath="E:\\var\\log\\elkTest\\error\\2018-11-30.log";
        mailService.sendAttachmentsMail("[email protected]", "主題：帶附件的郵件", "有附件，請查收！", filePath);
    }

    @Test
    public void sendInlineResourceMail() {
        String rscId = "neo006";
        String content="<html><body>這是有圖片的郵件：<img src=\'cid:" + rscId + "\' ></body></html>";
        String imgPath = "C:\\Users\\Admin\\Pictures\\Camera Roll\\9499189867_1476052069.jpg";

        mailService.sendInlineResourceMail("[email protected]", "主題：這是有圖片的郵件", content, imgPath, rscId);
    }

    @Test
    public void sendTemplateMail() {
        //建立郵件正文
        Context context = new Context();
        context.setVariable("id", "006");
        mailService.sendTemplateMail("[email protected]","主題：這是模板郵件",
                "emailTemplate",context);
    }
}

上面的郵箱和密碼是我亂填的，注意自己更改。
