在我的Java程序中,我必须输出一个HTML文件,其中包含发送或显示特定电子邮件等按钮,这些按钮保存在此java程序中(将在服务器上运行)。如何链接此HTML文件,以便在单击按钮时,它实际上调用java程序中的方法(例如发送电子邮件方法)并影响某些字段,例如存储电子邮件的列表?如果没有办法做到这一点,我怎样才能实现我想做的事情?谢谢。
这是我用于GUI的代码,但我不想要GUI。我想将所有这些代码转换为输出的HTML文件。基本上,代替这些代码,我需要输出一个与此GUI完全相同的HTML文件。我需要输出网页的原因是,当程序启动到服务器上时,GUI并不那么方便。我相信程序将始终运行,并且主要是我有一个timeTask,每天运行一次这个例程。

email是一个Email对象,它有一个使用JavaMail的sendEmailRecipient方法。此外,电子邮件的正文也是HTML,可能与此无关。
