Java封裝好的mail包發送電子郵件的類。本站提示廣大學習愛好者：（Java封裝好的mail包發送電子郵件的類）文章只能為提供參考，不一定能成為您想要的結果。以下是Java封裝好的mail包發送電子郵件的類正文
上面代碼是應用Java mail包封裝了一個發送郵件的類

{

}
}

}
應用舉例
String host = "168.xx.xx.xx"; //郵件辦事器的地址
String subject = "發送郵件的主題";
String sender = "test@gmail.com";
List<String> receivers = new ArrayList<String>();
receivers.add("user1@263.com");
receivers.add("user2@263.com");
String content = "郵件主題";
SendMail sendMail = new SendMail();
sendMail.setMailBasicInfo(host, sender, receivers);
sendMail.send(subject, content, null); //沒有附件
注釋也能夠是html內容，如
String content = "<html>具體信息：<a href='xxxx'>請點擊檢查！</a></html>";
我們再來看一個封裝好的類

挪用方法以下
public boolean sendMail() throws Exception {
List<String> receivers = new ArrayList<String>();
receivers.add("sunhao0550@163.com");
receivers.add("sunhao0550@sina.cn");
EmailServer.getInstance().sendHtmlMail("message_admin@163.com", "這裡是暗碼", "測試發送HTML郵件",
"<span style='color: red;font-size: 20pt'>測試發送HTML郵件</span><a href='http://www.百度.com' target='_blank'>鏈接到百度</a>", receivers);
return EmailServer.getInstance().sendTextMail("message_admin@163.com", "這裡是暗碼", "測試發送文本郵件",
"測試發送文本郵件測試發送文本郵件測試發送文本郵件", receivers);
}
PS:正在斟酌擴大,假如把這幾個類封在jar包中,若何停止郵件辦事器設置裝備擺設的擴大.
若有欠好的地方,迎接拍磚.
