通过Spring启动发送电子邮件"spring-boot-starter-mail"

Question

我正在尝试使用spring boot发送电子邮件,但我得到:

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)

我使用过这个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

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;
    }

这似乎是一个直接的,但不是我错过了什么!

我的建议是使用it.ozimov:spring-boot-email-core库,它将所有这些实现隐藏在一个名为的单个组件后面EmailService- 好吧,我也在开发库:).

你的例子是:

@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

它还支持一些模板引擎,如Freemarker,Mustache和Pebble,同时您可以扩展它以使用更多的模板引擎.此外,它还支持电子邮件安排和优先级(例如,密码恢复的高优先级和简报的低优先级.

LinkedIn上有一篇文章解释了如何使用它.它就在这里.

javax.mail.internet.MimeMessage除了通过via引入的版本之外,你还有类路径的第二个版本spring-boot-starter-mail.常见的罪魁祸首是Geronimo的JavaMail spec jar.无论它是哪个jar,您都需要将其从应用程序的依赖项中排除.如果您不确定它的来源,运行您的应用程序-verbose:class会告诉您.
