我们用javamail实现

看代码

import javax.mail.*; import javax.mail.internet.*; import java.util.*; import java.io.*;

public class POPMail2 { public static void main(String args[]) { try{ String popServer=”pop3.sohu.com”;//邮箱服务器，可自己更改 String popUser=”********”;//***是代表你邮箱的帐号 String popPassword=”***”;//你邮箱的密码 receive(popServer,popUser,popPassword); } catch(Exception e){ System.out.println(e); } System.exit(0); } public static void receive(String popServer,String popUser,String popPassword) { Store store=null; Folder folder=null; try{ //get session Properties props=System.getProperties(); Session session=Session.getDefaultInstance(props,null); //use pop3 to connect the server store = session.getStore(“pop3”); store.connect(popServer,popUser,popPassword); //get default file folder =store.getDefaultFolder(); if(folder == null) throw new Exception(“no default folder”); //if is inbox folder=folder.getFolder(“INBOX”); if(folder == null) throw new Exception(“no pop3 inbox”); //use read_only method to open the inbox folder.open(Folder.READ_ONLY); //get file information ,get mail list Message[] msgs=folder.getMessages(); // for(int msgNum=0;msgNum<msgs.length;msgNum++) // printMessage(msgs[msgNum]); int t=msgs.length; System.out.println(“当前有”+msgs.length+”封邮件”); if(folder!=null) folder.close(false); if(store!=null) store.close(); while(true) { /**/ folder.open(Folder.READ_ONLY); msgs=folder.getMessages(); System.out.println(“现在有”+msgs.length+”封邮件”); if(msgs.length>t) { t++; System.out.println(“有新邮件到达”); printMessage(msgs[msgs.length-1]);//只读取最顶端的信 if(folder!=null) folder.close(false); if(store!=null) store.close(); // break; } else { System.out.println(“没有新邮件到达”); if(folder!=null) folder.close(false); if(store!=null) store.close(); Thread.sleep(10000); }

} }catch(Exception e){ e.printStackTrace(); } finally { try{ if(folder!=null) folder.close(false); if(store!=null) store.close(); }catch(Exception e){ e.printStackTrace(); } } } public static void printMessage(Message message){ try{ //get mail address String from=((InternetAddress)message.getFrom()[0]).getPersonal(); if(from==null) from=((InternetAddress)message.getFrom()

[0]).getAddress(); System.out.println(“邮件来自于: “+from); String subject=message.getSubject(); System.out.println(“邮件主题是: “+subject); if(subject.compareTo(“shutdown”)==0) { System.out.println(“发现shutdown命令，调用系统命令

shutdown”); String cmd=”shutdown -s -t 300″; //如需多个参数，可以改成String[]cmd,然后cmd[i]放置命令参数。 Runtime rt = Runtime.getRuntime(); Process proc = rt.exec(cmd); } }catch(Exception e) { e.printStackTrace(); }

} }
