JavaMail简单接收邮件

一个简单的例子，收取所有邮件并在控制台输出。

package cn.jmail.test;

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

public class MailReceives {
public static void main(String[] args) {
String pop3Server = "pop3.163.com";
String protocol = "pop3";
String username = "xxxx";
String password = "xxxx";
Properties prop = new Properties();
prop.setProperty("mail.store.protocol", protocol);
prop.setProperty("mail.pop3.host", pop3Server);
Session mailSession = Session.getDefaultInstance(prop,null);
mailSession.setDebug(false);
try {
Store store = mailSession.getStore(protocol);
//登录验证
store.connect(pop3Server,username,password);
//获取邮箱账户
Folder folder = store.getFolder("inbox");
//设置访问权限
folder.open(Folder.READ_WRITE);
//获取所有邮件
Message[] messages = folder.getMessages();
for(int i=0; i<messages.length; i++){
//主题
String subject = messages[i].getSubject();
//发送者地址
String from = messages[i].getFrom()[0].toString();
System.out.println("第" + (i+1) + "封邮件的主题为：" + subject + "\t发件人地址为：" + from);
System.out.println("你想阅读此邮件吗（y/n）？");
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(System.in));
String input = bufferedReader.readLine();
if("y".equals(input.toLowerCase())){
messages[i].writeTo(System.out);
}
}
folder.close(false);
store.close();
} catch (NoSuchProviderException e) {
e.printStackTrace();
} catch (MessagingException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
