在 jhipster 项目中正确配置我的 smtp 设置答案

【问题标题】：correct configuration my smtp settings in jhipster project在 jhipster 项目中正确配置我的 smtp 设置
【发布时间】：2015-12-22 20:21:50
【问题描述】：

我的 jhipster 应用程序配置存在一些问题。这是我的配置文件的一部分：

mail:
    host: smtp.mail.yahoo.com
    port: 465
    username: My_smtp_login
    password: my_smtp_password
    protocol: smtp
    tls: true
    auth: true
    from: mymail@yahoo.pl
messages:
    cache-seconds: 1
thymeleaf:
    cache: false

还有我的日志：

2015-12-22 20:47:09.680 DEBUG 13428 --- [hero-Executor-2] com.sun.mail.smtp                        : useEhlo true, useAuth false

这不仅是 yahoo 的问题，我检查过 AOL、Gmail 和 Yandex，但 smtp 也存在同样的问题。 smtp配置问题出在哪里？

我找到了删除的信息

来自：mymail@yahoo.pl 应该有帮助，但在我的情况下它不起作用

【问题讨论】：

标签： java spring email jakarta-mail jhipster

【解决方案1】：

我和你有同样的错误。我的解决方案是将from: mymail@yahoo.pl（必须与雅虎邮件用户名相同）放到该部分：

jhipster: mail: from: mymail@yahoo.pl

也可以在 application-prod.yml 或 application-dev.yml 文件中找到，但在以下几行：

spring:
       mail:

部分。所以我的整个解决方案如下（使用您的示例凭据）：

spring:
        ...
          mail:
               host: smtp.mail.yahoo.com
               port: 587
               username: mymail@yahoo.pl
               password: my_smtp_password
               protocol: smtp
               tls: true
          properties.mail.smtp:
               auth: true
               starttls.enable: true
               ssl.trust: smtp.mail.yahoo.com

和：

jhipster:
         ...
         mail: 
              from: mymail@yahoo.pl

【讨论】：

【解决方案2】：

您是否检查过您是否可以从 JHipster 外部连接到该 SMTP 服务器，例如使用 telnet？也许你被防火墙阻止了。

您还应该为其他属性设置spring.mail.properties.mail.smtp，如下所示。

spring:
    mail:
        host: smtp.mail.yahoo.com
        port: 587
        username: My_smtp_login
        password: my_smtp_password
        protocol: smtp
        tls: true
        properties.mail.smtp:
             auth: true
             starttls.enable: true
             ssl.trust: smtp.mail.yahoo.com
        from: mymail@yahoo.pl

【讨论】：

谢谢 :) 向前迈出了一大步，似乎应用程序可以连接到 smtp，但仍然有问题：>2015-12-24 10:06:51.146 WARN 7709 --- [ -app-Executor-2] >net.ddemo.service.MailService ：电子邮件无法发送到 >user 'xxx@xxx.pl'，例外是：失败的消息：>com.sun.mail.smtp.SMTPSendFailedException : >arguments > 中的 501 语法错误； >嵌套异常是： > com.sun.mail.smtp.SMTPSenderFailedException: 501 Syntax >参数错误我也尝试关注此链接：goo.gl/lkfg6a 但它不起作用

【解决方案3】：

我发现的大多数示例都使用来自以下位置的经典配置：https://jhipster.github.io/tips/011_tip_configuring_email_in_jhipster.html

我遇到了与您尝试使用 Exchange Server 连接时相同的错误。修复方法是将 SMTP 属性添加到 spring:mail，以便在 Session 中加载这些属性

所以我在配置文件 application-dev.yml 中添加了我需要的 SMTP 属性（见：https://javamail.java.net/nonav/docs/api/com/sun/mail/smtp/package-summary.html）

spring:
    mail:
        host: 10.10.10.10
        port: 25
        username: 
        password: 
        properties.mail.smtp:
            host: 10.10.10.10
            port: 25
            auth: false
            starttls.enable: false
            connectiontimeout: 180000
            timeout: 180000

jhipster:
    mail: 
        from: yourproject@something.com

为了检查 Session，我在 MailService 类中添加了一些调试日志。

类：your.pack.service.MailService.java

@Inject
private MailProperties mailProperties;

@Async
public void sendEmail(String to, String subject, String content, boolean isMultipart, boolean isHtml) {
    log.debug("Send e-mail[multipart '{}' and html '{}'] to '{}' with subject '{}' and content={}",
        isMultipart, isHtml, to, subject, content);

    // Prepare message using a Spring helper
    MimeMessage mimeMessage = javaMailSender.createMimeMessage();
    try {
        MimeMessageHelper message = new MimeMessageHelper(mimeMessage, isMultipart, CharEncoding.UTF_8);
        message.setTo(to);
        message.setFrom(jHipsterProperties.getMail().getFrom());
        message.setSubject(subject);
        message.setText(content, isHtml);

        // --- Debug Code
        log.debug("----- spring: mail: -----");
        log.debug("spring mail: host={}", mailProperties.getHost());
        log.debug("spring mail: port={}", mailProperties.getPort());
        log.debug("spring mail: username={}", mailProperties.getUsername());
        log.debug("spring mail: password={}", mailProperties.getPassword());
        log.debug("spring mail: protocol={}", mailProperties.getProtocol());

        log.debug("----- spring: mail: properties.mail.smtp -----");
        for (Entry<String, String> entry : mailProperties.getProperties().entrySet()) {
            log.debug("properties.mail.smtp: {}={}", entry.getKey(), entry.getValue());
        }

        log.debug("----- session object -----");
        for (Entry<Object, Object> entry : message.getMimeMessage().getSession().getProperties().entrySet()) {
            log.debug("session: {}={}", entry.getKey(), entry.getValue());
        }
        // --- Debug Code

        javaMailSender.send(mimeMessage);
        log.debug("Sent e-mail to User '{}'", to);
    } catch (Exception e) {
        log.warn("E-mail could not be sent to user '{}', exception is: {}", to, e.getMessage());
    }
}

结果，所有属性都加载到了会话中

your.pack.service.MailService    : Sending activation e-mail to 'thenewuser@server.com'
your.pack.service.MailService    : Send e-mail[multipart 'false' and html 'true'] to 'thenewuser@server.com' with subject 'YourProject account activation' and content=<!DOCTYPE html>
...
...
your.pack.service.MailService    : ----- spring: mail: -----
your.pack.service.MailService    : spring mail: host=10.10.10.10
your.pack.service.MailService    : spring mail: port=25
your.pack.service.MailService    : spring mail: username=
your.pack.service.MailService    : spring mail: password=
your.pack.service.MailService    : spring mail: protocol=smtp
...
your.pack.service.MailService    : ----- spring: mail: properties.mail.smtp -----
your.pack.service.MailService    : properties.mail.smtp: mail.smtp.port=25
your.pack.service.MailService    : properties.mail.smtp: mail.smtp.auth=false
your.pack.service.MailService    : properties.mail.smtp: mail.smtp.starttls.enable=false
your.pack.service.MailService    : properties.mail.smtp: mail.smtp.timeout=180000
your.pack.service.MailService    : properties.mail.smtp: mail.smtp.host=10.10.10.10
your.pack.service.MailService    : properties.mail.smtp: mail.smtp.connectiontimeout=180000
...
your.pack.service.MailService    : ----- session object -----
your.pack.service.MailService    : session: mail.smtp.starttls.enable=false
your.pack.service.MailService    : session: mail.smtp.port=25
your.pack.service.MailService    : session: mail.smtp.host=10.10.10.10
your.pack.service.MailService    : session: mail.smtp.auth=false
your.pack.service.MailService    : session: mail.smtp.timeout=180000
your.pack.service.MailService    : session: mail.smtp.connectiontimeout=180000

至少对我来说，它有效！
