Question

我使用spring boot2。我尝试发送邮件。服务器是我的build.gradle中的Outlook

compile（'org.springframework.boot：spring-boot-starter-mail'）

在我的门面课中

for (FactoryEmailNC factoryEmail : factoryEmails) {

    String message = mailContentBuilder.build(factoryEmail);

    if (factoryEmail.getEmails() != null && !factoryEmail.getEmails().isEmpty()) {

        mailService.sendHtmlMail(factoryEmail.getEmails(), "Not compliant", message);

        //query to specify email has been sent.
        setSampleEmailSent(factoryEmail);
    }
}

private void setSampleEmailSent(FactoryEmailNC factoryEmail) {
    ....
    samplesServices.setEmailsSent(testSampleIdEmailSent);
}

在我的SamplesServices类中

@Transactional
public void setEmailsSent(Map<String, List<SampleId>> testSampleIdEmailSent){
    //call to repository, set flag email sent to true   
    ...
}


public class MailServiceImpl(){

    @Autowired
    private JavaMailSender javaMailSender;

    @Async
    public void sendHtmlMail(List<String> to, String subject, String body) throws MessagingException {

        MimeMessage mail = javaMailSender.createMimeMessage();
        MimeMessageHelper helper = new MimeMessageHelper(mail, true);
        ...
        helper.setTo(to.stream().toArray(String[]::new)); //line 64
        javaMailSender.send(mail);
    }


}

实际上已发送电子邮件，但似乎未调用setSampleEmailSent，因为电子邮件标志仍为false

org.springframework.mail.MailSendException：失败消息： javax.mail.MessagingException：异常读取响应；嵌套的异常是：java.net.SocketTimeoutException：读取超时于 org.springframework.mail.javamail.JavaMailSenderImpl.doSend（JavaMailSenderImpl.java:490）〜[spring-context-support-5.1.5.RELEASE.jar！/：5.1.5.RELEASE]在 org.springframework.mail.javamail.JavaMailSenderImpl.send（JavaMailSenderImpl.java:360）〜[spring-context-support-5.1.5.RELEASE.jar！/：5.1.5.RELEASE]在 org.springframework.mail.javamail.JavaMailSenderImpl.send（JavaMailSenderImpl.java:355）〜[spring-context-support-5.1.5.RELEASE.jar！/：5.1.5.RELEASE]在 com.mermacon.service.MailServiceImpl.sendHtmlMail（MailServiceImpl.java:64）〜[classes！/：na]

在我的应用程序属性中

spring.mail.properties.mail.smtp.connectiontimeout = 5000

spring.mail.properties.mail.smtp.timeout = 3000

spring.mail.properties.mail.smtp.writetimeout = 5000

spring.mail.properties.from=info@meracon.com

spring.mail.host = mail.oldubi.com

spring.mail.port = 25

知道为什么发送电子邮件但仍然超时吗？

仅当我发送多封电子邮件时我才会超时发送1封电子邮件的日志文件 https://pastebin.com/6y6n8MV5

发送1封电子邮件后的日志文件 https://pastebin.com/j2sT7qHu

我在发送的每封电子邮件之间设置了一个线程睡眠，超时消失

电子邮件已发送但超时
