通过Spring Boot“ spring-boot-starter-mail”发送电子邮件

spring-boot

我正在尝试使用Spring Boot发送电子邮件,但得到了:

java.lang.UnsupportedOperationException: Method not yet implemented
        at javax.mail.internet.MimeMessage.<init>(MimeMessage.java:89)
        at org.springframework.mail.javamail.SmartMimeMessage.<init>(SmartMimeMessage.java:52)
        at org.springframework.mail.javamail.JavaMailSenderImpl.createMimeMessage(JavaMailSenderImpl.java:325)

我已经使用了这个Maven条目:

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.2.6.RELEASE</version>
    </parent>

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <version>1.2.6.RELEASE</version>
        </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-mail</artifactId>
        <version>1.2.6.RELEASE</version>
    </dependency>

application.properties:

spring.mail.host=smtp.gmail.com
spring.mail.port= 25
spring.mail.username= test
spring.mail.password= test

和我的代码:

@Autowired
    private JavaMailSender javaMailSender;

private void send() {
        MimeMessage mail = javaMailSender.createMimeMessage();
        try {
            MimeMessageHelper helper = new MimeMessageHelper(mail, true);
            helper.setTo("mymail@mail.co.uk");
            helper.setReplyTo("someone@localhost");
            helper.setFrom("someone@localhost");
            helper.setSubject("Lorem ipsum");
            helper.setText("Lorem ipsum dolor sit amet [...]");
        } catch (MessagingException e) {
            e.printStackTrace();
        } finally {}
        javaMailSender.send(mail);
        //return helper;
    }

这似乎很简单,但是我不缺少什么!

我的建议是使用it.ozimov:spring-boot-email-core库,该库将所有这些实现隐藏在一个单独的组件后面EmailService-很好,我也在开发该库:)。

您的示例将是:

@Autowired
public EmailService emailService;

public void sendEmail(){
   final Email email = DefaultEmail.builder()
        .from(new InternetAddress("mymail@mail.co.uk"))
        .replyTo(new InternetAddress("someone@localhost"))
        .to(Lists.newArrayList(new InternetAddress("someone@localhost")))
        .subject("Lorem ipsum")
        .body("Lorem ipsum dolor sit amet [...]")
        .encoding(Charset.forName("UTF-8")).build();

   emailService.send(email);
}

具有以下内容application.properties

spring.mail.host=your.smtp.com
spring.mail.port=587
spring.mail.username=test
spring.mail.password=test
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true

它还支持某些模板引擎,例如 FreemarkerMustachePebble
,而您可以扩展它以使用更多的模板引擎。此外,它还支持电子邮件调度和优先级排序(例如,密码恢复的高优先级和新闻通讯的低优先级)。

LinkedIn上有一篇文章介绍了如何使用它。这是在这里
