JavaMail操作的总结(2)

//此段代码用来进行服务器对用户的认证
public class Email_Autherticator extends Authenticator
{
public Email_Autherticator()
{
super();
}
public PasswordAuthentication getPasswordAuthentication()
{
return new PasswordAuthentication(username,password);
}
}
//该程序为接收邮件
void jButton2_actionPerformed(ActionEvent e) {
try
{
Properties props = System.getProperties(); //获取系统变量
Authenticator auth = new Email_Autherticator();
props.put("mail.smtp.host",host);
props.put("mail.smtp.auth","true");
Session session = Session.getDefaultInstance(props,auth); //建立session
Store store = session.getStore("pop3");
store.connect(host,username,password);
//After connecting to the Store,you can get a Folder,which must be opened before you can read messages from it:
Folder folder = store.getFolder("INBOX");//连接到Store后，取得一个文件夹，一般默认的是INDEX
folder.open(Folder.READ_WRITE);//READ_ONLY为打开方式
Message message[] = folder.getMessages();//从文件夹获取邮件信息
//可以用两种方式去获得邮件信息，getContent()用来获得邮件的主体信息。而WriteTo()可以用来获得邮件的全部信息，包括头部信息
// System.out.println(((MimeMessage)message).getContent());
for (int i=0,n=message.length;i {
String out_from_person = ((InternetAddress)message[i].getFrom()[0]).getPersonal();
String out_from_address = ((InternetAddress)message[i].getFrom()[0]).getAddress();
System.out.println("From:"+out_from_person+" ");
System.out.println("Address:"+out_from_address+" ");
String out_subject = message[i].getSubject();
System.out.println("Subject:"+out_subject+" ");
//以下代码用来获得邮件的正文信息
Part messagePart = message[i];
Object out_content = messagePart.getContent();
if (out_content instanceof Multipart)
