Java 邮件附件在 Tomcat 上不起作用

Question

我有一个通过电子邮件发送确认的应用程序。电子邮件部分利用 Commons Mail API。发送邮件的简单代码如下所示；

import org.apache.commons.mail.*;
...
// Create the attachment
EmailAttachment attachment = new EmailAttachment();
attachment.setURL(new URL("http://cashew.org/doc.pdf"));
attachment.setDisposition(EmailAttachment.ATTACHMENT);
attachment.setDescription("Testing attach");
attachment.setName("doc.pdf");

// Create the email message
MultiPartEmail email = new MultiPartEmail();
email.setHostName("mail.cashew.com");
email.addTo("[email protected]");
email.setFrom("[email protected]");
email.setSubject("Testing);
email.setMsg("testing message");

// add the attachment
email.attach(attachment);

// send the email
email.send();

我的问题是，当我从 Eclipse 执行此应用程序时，我收到带有附件的电子邮件，没有任何问题。但是当我将应用程序部署到 Tomcat 服务器时（我已经

尝试了版本 5 和 6，但没有任何效果），电子邮件将发送以下内容；

------=_Part_0_25002283.1275298567928
Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit

我还注意到的一件事是，标题信息不显示 TO 和主题值。嗯，很奇怪。 我必须指出，上面不是DEBUG生成的，它是我的outlook客户端中收到的实际消息。

有人可以帮我吗！

更新：该应用程序非常简单。附件和文本消息也作为单独的部分。

   public final void Email(String from, String to, String cc,
          String subject, String message, String doc, String bcc) {

      MultiPartEmail email = new MultiPartEmail();

    try {

        if (!(doc == null)) {
                     EmailAttachment attachment = new EmailAttachment();
                     attachment.setURL(new URL("http://cashew.org/doc.pdf"));
         attachment.setDisposition(EmailAttachment.ATTACHMENT);
         attachment.setDescription("Testing attach");
         attachment.setName("doc.pdf");
                     email.attach(attachment);  
        }


        email.setHostName("mail.cashew.com");

        // [ Set Header details
        email.setTo(getAddress(to));
        email.setFrom(from);
        email.setSubject(subject);


        if (!(cc == null)) {
              eEmail.setCc(getAddress(cc));
        }

        if (!(bcc == null)) {
            email.setBcc(getAddress(bcc));
        }

        email.setMsg(message);

        email.send();


    } catch (Exception ex) {
        ex.printStackTrace();
    }
}

有谁知道发生了什么事吗？

Answer 1

这就是问题

原因：所描述的问题是由传递依赖引起的
Apache CXF 2 或 Axiom。

解决方案：要解决此问题，请排除 geronimo-javamail_1.4_spec
从构建中，只依赖javax的mail-1.4.x.jar。
