使用Java Mail API读取邮件内容 [英] Reading Mail Content Using Java Mail API

问题描述

我能够正确获取from字段和subject字段，但即使我使用toString（）方法，我也会以对象格式获取邮件内容..

I am able to get the from field and subject field correctly , But i am getting the Mail Content in Object Format even though i m using toString() method..

请查看以下源代码

    try {
        Session session = Session.getInstance(props, null);
        Store store = session.getStore();
        store.connect("imap.gmail.com", "[e-mail]", "****");
        Folder inbox = store.getFolder("INBOX");
        inbox.open(Folder.READ_ONLY);
        Message msg = inbox.getMessage(inbox.getMessageCount());
        Address[] in = msg.getFrom();
        for (Address address : in) {
            System.out.println("FROM:" + address.toString());
        }

        Object obj = msg.getContent();
        //Multipart mp = (Multipart)obj;

        Multipart mp = (Multipart) msg.getContent();
       // MimeBodyPart part = (MimeBodyPart)mp.getBodyPart(0);
        BodyPart bp = ((Multipart) msg.getContent()).getBodyPart(0);

        // Object body = msg.getContent();

        //String value = String.valueOf(body);

        System.out.println("SENT DATE:" + msg.getSentDate());
        System.out.println("SUBJECT:" + msg.getSubject());
        System.out.println("CONTENT:" + bp.getContent().toString());
    } catch (Exception mex) {
        mex.printStackTrace();
    }
}

}

    output console:

   FROM:Myname <[e-mail]>
   SENT DATE:Tue Nov 05 12:28:24 IST 2013
   SUBJECT:test
  CONTENT:javax.mail.internet.MimeMultipart@5117f31e

推荐答案

您需要遍历所有多部分，然后检查 MIME Part 的类型，以便知道您是否必须将其视为文本或附件。

You need to iterate through all multiparts, then check MIME type of the Part in order to know if you have to treat it like a text or an attachment.

for(int i=0;i<multipart.getCount();i++) {
    BodyPart bodyPart = multipart.getBodyPart(i);
    if (bodyPart.isMimeType("text/*")) {
        String s = (String) bodyPart.getContent();
    }
}
