要将解析的UIDL文件存入集合中,可以使用JavaMail API的UIDFolder接口中的getUIDs()方法获取所有邮件的UIDL并将其存入数组中,然后将数组转换为集合。以下是示例代码:
```
import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;
public class ParseUIDL {
public static void main(String[] args) throws Exception {
String host = "imap.gmail.com";
String username = "yourusername@gmail.com";
String password = "yourpassword";
Properties properties = new Properties();
properties.setProperty("mail.store.protocol", "imaps");
Session session = Session.getDefaultInstance(properties, null);
Store store = session.getStore();
store.connect(host, username, password);
Folder inbox = store.getFolder("INBOX");
inbox.open(Folder.READ_ONLY);
UIDFolder uidFolder = (UIDFolder) inbox;
Message[] messages = inbox.getMessages();
long[] uids = uidFolder.getUIDs(messages);
List<String> uidlList = new ArrayList<>();
for (long uid : uids) {
uidlList.add(String.valueOf(uid));
}
inbox.close(false);
store.close();
System.out.println("UIDL list: " + uidlList);
}
}
```
在上面的示例代码中,我们使用JavaMail API的UIDFolder接口的getUIDs()方法获取所有邮件的UIDL,并将其存入long类型的数组中。然后,我们将数组转换为String类型的集合,以便我们可以在控制台上打印UIDL列表。您可以根据自己的需要修改代码。
