簡單Java 發送郵件執行個體代碼

 

這裡用apache的commons-email(http://commons.apache.org/proper/commons-email/download_email.cgi)和java mail()發送郵件.
我的需求僅僅是在系統異常時發個警示郵件,所以,不涉及到附件之類的東西,代碼很簡單:

 

代碼如下

public static void sendMail(String receiverAddress,String subject,String message)  {  MultiPartEmail email = new MultiPartEmail();          try {              //smtp server：              email.setHostName("smtp.163.com");              // Charset              email.setCharset("utf-8");              // receiver's address                        email.addTo(receiverAddress);              // 寄件者郵箱             email.setFrom("***@163.com");              //帳號密碼             email.setAuthentication("***", "***");             //主題             email.setSubject(subject);              //資訊             email.setMsg(message);              // 發送              email.send();          } catch (EmailException e) {              e.printStackTrace();          }  }
