Java：打开默认邮件应用程序并创建新邮件并填充To和Subject字段 [英] Java: Open default mail application and create new mail and populate To and Subject fields

问题描述

是否有Java中的功能来生成一段可以打开的代码用户PC上的默认电子邮件应用程序？ （我想几乎喜欢一个花哨的邮件链接...）

如果有 - 是否可以填充To和Subject字段等字段？

谢谢，
Mike。

解决方案

Desktop.mail（URI mailtoURI ）是您的朋友！

Javadoc：

启动邮件撰写窗口用户默认邮件客户端，填写由mailto：URI指定的邮件字段。

mailto：URI可以指定包含to，cc，主题，正文等。请参见 mailto URL方案（RFC 2368）， mailto：URI规范详细信息。

示例代码：

 桌面桌面; 
 if（Desktop.isDesktopSupported（）
&&（desktop = Desktop.getDesktop（））。isSupported（Desktop.Action.MAIL））{
 URI mailto = new URI（邮寄地址：[e-mail]主题=你好％20World）; 
 desktop.mail（mailto）; 
} else {
 // TODO fallback to some Runtime.exec（..）voodoo？ 
抛出新的RuntimeException（桌面不支持mailto;邮件已经死了））; 
} 
  

Just wondering if anyone can help me with a problem I've come across in Java.

Is there functionality within Java to produce a section of code that will open the default email application on a user's PC? (I guess almost like a fancy mailto link...)

If there is - is it possible to populate fields such as the To and Subject fields?

Thanks, Mike.

解决方案

Desktop.mail(URI mailtoURI) is your friend!

Javadoc:

Launches the mail composing window of the user default mail client, filling the message fields specified by a mailto: URI.

A mailto: URI can specify message fields including "to", "cc", "subject", "body", etc. See The mailto URL scheme (RFC 2368) for the mailto: URI specification details.

Example Code:

Desktop desktop;
if (Desktop.isDesktopSupported() 
    && (desktop = Desktop.getDesktop()).isSupported(Desktop.Action.MAIL)) {
  URI mailto = new URI("mailto:[e-mail]?subject=Hello%20World");
  desktop.mail(mailto);
} else {
  // TODO fallback to some Runtime.exec(..) voodoo?
  throw new RuntimeException("desktop doesn't support mailto; mail is dead anyway ;)");
}
