Java: Open default mail application and create new mail and populate To and Subject fields
提问by Mike
Just wondering if anyone can help me with a problem I've come across in Java.
只是想知道是否有人可以帮助我解决我在 Java 中遇到的问题。
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...)
Java 中是否有功能可以生成一段代码来打开用户 PC 上的默认电子邮件应用程序？（我想几乎就像一个花哨的mailto链接......）
If there is - is it possible to populate fields such as the To and Subject fields?
如果有 - 是否可以填充诸如“收件人”和“主题”字段之类的字段？
Thanks, Mike.
谢谢，迈克。

Example Code:
示例代码：
Desktop desktop;
if (Desktop.isDesktopSupported()
&& (desktop = Desktop.getDesktop()).isSupported(Desktop.Action.MAIL)) {
URI mailto = new URI("mailto:[email protected]?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 ;)");
}
