Wildfly 9.1 smtp 邮件子干 - 无法连接到主机，端口：localhost，25；超时-1；

Question

我正在使用 wildfly 一段时间，但我无法使其邮件子系统正常工作。我看过很多教程如何设置它，无论是通过 Web 控制台、CLI 还是直接在standalone.xml 中，所以我很确定我的配置是正确的：

<subsystem xmlns="urn:jboss:domain:mail:2.0">
        <mail-session debug="true" name="Gmail" jndi-name="java:jboss/mail/Gmail" from="MAILFROM">
            <smtp-server outbound-socket-binding-ref="mail-smtp" ssl="true" username="MAILFROM" password="PASSWORD"/>
        </mail-session>
</subsystem>
<outbound-socket-binding name="mail-smtp">
        <remote-destination host="smtp.gmail.com" port="465"/>
</outbound-socket-binding>

然后在我的 Java 文件中：

@Resource(mappedName = "java:jboss/mail/Gmail")
private javax.mail.Session gmailSession;

public void sendEmail(String to,String subject,String msg){
 Message message = new MimeMessage(gmailSession);
 message.setFrom(newInternetAddress("MAILFROM"));
 message.setRecipients(Message.RecipientType.TO,
 InternetAddress.parse(to));
 message.setSubject(subject);
 message.setContent(msg,"text/html");
 Transport.send(message);}

我得到：

奇怪的是，在直接使用 javax.mail API 时，它具有相同的属性，如下所示：

public void sendEmail(String to,String subject,String msg){
        Properties properties = System.getProperties();
        String user = "MAILFROM";
        String passwd = "PASSWORD";
        properties.setProperty("mail.smtp.auth", "true");
        properties.setProperty("mail.smtp.starttls.enable", "true");
        properties.setProperty("mail.smtp.host", "smtp.gmail.com");
        properties.setProperty("mail.smtp.port", "587");
        javax.mail.Session gmailSession = javax.mail.Session.getInstance(properties,
                  new javax.mail.Authenticator() {
                    protected PasswordAuthentication getPasswordAuthentication() {
                        return new PasswordAuthentication(user, passwd);
                    }
                  });
        Message message = new MimeMessage(gmailSession);
        message.setFrom(new InternetAddress("MAILFROM"));
        message.setRecipients(Message.RecipientType.TO,
        InternetAddress.parse(to));
        message.setSubject(subject);
        message.setContent(msg,"text/html");
        Transport.send(message);

我试图解决这个问题有两个原因：

1. 我想在standalone.xml 中而不是在我的java 类中拥有我的凭据。
2. 主要是因为我讨厌有什么奇怪的东西，我无法让它发挥作用！

我不明白的第二件事是为什么我会得到这个异常：

尝试通过我提到的第二种方法发送电子邮件时。仅当我使用standalone.bat 命令从控制台启动我的wildfly 服务器时才会出现此错误。如果我通过eclipse“在服务器上运行”运行它，它可以工作。第二次糊涂了。我试图通过将我的自签名证书添加到 jdks cacerts 来解决第二个问题，但它没有帮助。

带有@Resource 的Java 代码是什么类？很可能没有注入资源，因为您的代码不在某种托管 bean/类中。检查 gmailSession 是否为非空，以确保注入工作正常。

证书路径错误肯定是您的信任库中的证书有问题。通常，Gmail 证书应使用默认信任存储进行验证。也许您有拦截请求的防病毒产品？你查过JavaMail FAQ entry吗？
