邮件不呈现html并且格式错误

Question

我完全不明白这个问题。如果我在作为java应用程序运行时从main方法尝试，那么邮件以正确的主题和内容格式完美地出现。而当我从localhost尝试时，它以错误的格式出现，例如

------=_Part_0_1765202668.1460463643056Content-Type： text/html； charset=utf-8 Content-Transfer-编码： 7bit

我的内容

------=\u Part\u 0\u 1765202668.14604636056--

我已经添加了所有相关的JAR（javax.mail）。无论内容是什么，都只会是这样。这是同一段代码，它在main方法中运行良好，但在本地主机中运行不好。有什么想法吗？

一些相关代码

MimeMessage msg = new MimeMessage(session);
    msg.setFrom(new InternetAddress(this.from));
    if ((this.replyTo != null) && (!this.replyTo.equals("")))
        msg.setReplyTo(InternetAddress.parse(this.replyTo));
    msg.setSentDate(new Date());
    InternetAddress[] address = InternetAddress.parse(this.to);
    msg.setRecipients(Message.RecipientType.TO, address);

    if (this.cc != null) {
        InternetAddress[] address1 = InternetAddress.parse(this.cc);
        msg.setRecipients(Message.RecipientType.CC, address1);
    }

    if (this.bcc != null) {
        InternetAddress[] address2 = InternetAddress.parse(this.bcc);
        msg.setRecipients(Message.RecipientType.BCC, address2);
    }
    msg.setSubject(this.subject);

    Multipart mp = new MimeMultipart();

    MimeBodyPart mbp = new MimeBodyPart();
    mbp.setContent(this.body,"text/html;charset=utf-8");

    mp.addBodyPart(mbp);

    if (this.attachfiles != null) {
        for (Enumeration e = this.attachfiles.keys(); e.hasMoreElements();) {
            String filename = (String) e.nextElement();
            mbp = new MimeBodyPart();

            FileDataSource fds = new FileDataSource(
                    (String) this.attachfiles.get(filename));
            mbp.setDataHandler(new DataHandler(fds));
            mbp.setFileName(filename);

            mp.addBodyPart(mbp);
        }

    }

    msg.setContent(mp);

    msg.setSentDate(new Date());

    Transport.send(msg);

pom出现问题。xml证明包中存在冲突。Tomcat在Maven构建中自动包含自己的JavaMail包，该包来自web项目中的另外两个jar，这导致了问题，而不是从标准JavaMail jar导入。

只需排除以下jar

    <dependency>
    <groupId>org.apache.ws.commons.axiom</groupId>
    <artifactId>axiom-api</artifactId>
    <version>1.2.7</version>
    <exclusions>
        <exclusion>
            <artifactId>geronimo-javamail_1.4_spec</artifactId>
            <groupId>org.apache.geronimo.specs</groupId>
        </exclusion>
        <exclusion>
            <artifactId>geronimo-activation_1.1_spec</artifactId>
            <groupId>org.apache.geronimo.specs</groupId>
