Question

我使用以下代码通过Hotmail服务发送电子邮件，就像User Guide

一样

@Override
public Boolean SendMsg(String title, String Content, String receiver, String sender) {
    try {
        HtmlEmail email = new HtmlEmail();
        final String username = s_address;
        final String password = s_pass;
        email.setHostName(s_smtp);
        email.setSmtpPort(Integer.parseInt(s_smtpp));
        email.setAuthentication(username, password);
        email.setSmtpPort(Integer.parseInt(s_smtpp));
        switch (c_smtps) {
            case '1':
                email.setSSL(true);
                email.setSslSmtpPort(s_smtpp);
            case '2':
                email.setTLS(true);
        }
        email.addTo(receiver);
        email.setFrom(s_address, sender);
        email.setSubject(title);
        // set the html message
        email.setHtmlMsg(Content);

        // set the alternative message
        email.setTextMsg(net.shisoft.util.common.html.Session.html2text(Content, true));
        email.send();
        return true;
    } catch (EmailException ex) {
        Logger.getLogger(ClassMail.class.getName()).log(Level.SEVERE, null, ex);
    }
    return false;
}

但我得到org.apache.commons.mail.EmailException: Sending the email to the following server failed : smtp.live.com:587例外。

经过一番搜索后，我发现有人遇到同样的问题，但没有正确答案（我依旧添加以下代码

// add handlers for main MIME types
MailcapCommandMap mc = (MailcapCommandMap) CommandMap.getDefaultCommandMap();
mc.addMailcap("text/html;; x-java-content-handler=com.sun.mail.handlers.text_html");
mc.addMailcap("text/xml;; x-java-content-handler=com.sun.mail.handlers.text_xml");
mc.addMailcap("text/plain;; x-java-content-handler=com.sun.mail.handlers.text_plain");
mc.addMailcap("multipart/*;; x-java-content-handler=com.sun.mail.handlers.multipart_mixed");
mc.addMailcap("message/rfc822;; x-java-content-handler=com.sun.mail.handlers.message_rfc822");
CommandMap.setDefaultCommandMap(mc);

但不工作。。我真的不知道如何解决这个问题

Answer 1

此异常几乎总是由于您的环境中存在问题应用程序运行通常，JavaMail将使用JAF来查找DataContentHandler 对于邮件中的每种数据类型。 JAF在中读取配置文件 JavaMail mail.jar文件。如果您的类加载器出现问题，JAF可能不会能够读取该配置文件。

有时有用的解决方法是：

Thread.currentThread().setContextClassLoader(this.getClass().getClassLoader());

在主应用程序类中。

Answer 2

您可以在mail.jar文件夹中包含最新的activation.jar和$CATALINA_HOME/lib，然后重新启动tomcat。
