這里使用的是JavaMail技術，前臺使用了fckeditor做郵件美化，由于只是示例，后臺發(fā)送時只是將郵件保存在本地，但是可以查看，如果需要實際發(fā)送，請參考我的其他博客文章，我寫了很多關于郵件發(fā)送的示例！
JSP頁面頁面除了引用fckeditor外，要注意我們是需要發(fā)送附件的：

然后到Servlet處理附件和信息，這里就不做異常處理了，出錯直接報錯：

這里也沒有驗證，接收到信息后組裝一個郵件實體對象，傳遞到發(fā)送接口中發(fā)送：
實體，我就不寫ｇｅｔ和ｓｅｔ方法了：

我們把郵件發(fā)送了C盤，可以到C盤查看，如果需要實際發(fā)送，可以參考我的其他博客，有專門說明！
