用Java接收邮件

需要的jar包同上一篇“用Java发送邮件”。代码如下：

 

import java.util.Properties;

import javax.mail.FetchProfile;
import javax.mail.Folder;
import javax.mail.Message;
import javax.mail.Session;
import javax.mail.Store;
import javax.mail.internet.InternetAddress;

public class Receive 
{
	public Receive()
	{
		
	}
	
	public static void main(String[] args)
	{
		receive();
	}
	
	public static void receive()
	{
		try 
		{   
            Properties props = new Properties();   
            Session s = Session.getInstance(props);   
            Store store = s.getStore("pop3");   
            
            //对应改成自己的用户名和密码
            store.connect("pop.163.com", "username", "password");   
  
            Folder folder = store.getFolder("Inbox");   
            folder.open(Folder.READ_WRITE);   
  
            FetchProfile profile = new FetchProfile();   
            profile.add(FetchProfile.Item.ENVELOPE);   
            Message arraymessage[] = folder.getMessages();   
            folder.fetch(arraymessage, profile);   
  
            System.out.println("收件箱的邮件数：" + arraymessage.length);   
            for (int i = 0; i < arraymessage.length; i++) 
            {   
                //邮件发送者   
                String from = arraymessage[i].getFrom()[0].toString();   
                InternetAddress ia = new InternetAddress(from);   
                
                System.out.println("******" + i + "******");
                
                System.out.println("From:" + ia.getPersonal() + '(' + ia.getAddress() + ')');   
                
                //邮件标题   
                System.out.println("Title:" + arraymessage[i].getSubject());   
                
                //邮件大小   
                System.out.println("Size:" + arraymessage[i].getSize());   
                
                //邮件发送时间   
                System.out.println("Date:" + arraymessage[i].getSentDate());  
            }   
  
            folder.close(false);   
            
            store.close();   
            
        } catch (Exception ee) {   
            ee.printStackTrace();   
        }   
	}
}
