java 收 特定日期邮件_java mail解析邮件并获取最近时间的指定邮件

以下是使用 JavaMail 解析邮件并获取最近时间的指定邮件的示例代码：

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

public class EmailParser {
    public static void main(String[] args) throws Exception {
        String host = "your-hostname";
        String username = "your-username";
        String password = "your-password";

        // Set properties for IMAP server
        Properties props = new Properties();
        props.setProperty("mail.store.protocol", "imaps");
        props.setProperty("mail.imaps.host", host);
        props.setProperty("mail.imaps.user", username);
        props.setProperty("mail.imaps.password", password);

        // Get the default Session object.
        Session session = Session.getDefaultInstance(props, null);

        // Get a Store object that implements the specified protocol.
        Store store = session.getStore("imaps");

        // Connect to the specified server.
        store.connect();

        // Open the INBOX folder.
        Folder inbox = store.getFolder("INBOX");
        inbox.open(Folder.READ_ONLY);

        // Search for messages sent on a specific date.
        Calendar cal = Calendar.getInstance();
        cal.set(2021, Calendar.MAY, 1); // Set the date to May 1, 2021
        Date searchDate = cal.getTime();
        SearchTerm term = new ReceivedDateTerm(ComparisonTerm.EQ, searchDate);
        Message[] messages = inbox.search(term);

        // Find the most recent email with a specific subject.
        Message latestMessage = null;
        for (int i = messages.length - 1; i >= 0; i--) {
            Message message = messages[i];
            if (message.getSubject().equals("Your Subject Here")) {
                latestMessage = message;
                break;
            }
        }

        // Print the content of the latest message.
        if (latestMessage != null) {
            System.out.println("Subject: " + latestMessage.getSubject());
            System.out.println("From: " + Arrays.toString(latestMessage.getFrom()));
            System.out.println("To: " + Arrays.toString(latestMessage.getRecipients(Message.RecipientType.TO)));
            System.out.println("Date: " + latestMessage.getSentDate());
            System.out.println("Content: " + latestMessage.getContent().toString());
        } else {
            System.out.println("No email found with the specified subject.");
        }

        // Close the folder and store objects.
        inbox.close(false);
        store.close();
    }
}

请将 `your-hostname`, `your-username` 和 `your-password` 替换为您的实际值。此代码将连接到 IMAP 服务器，打开收件箱文件夹，搜索在指定日期发送的邮件，然后查找特定主题的最新邮件，并打印其内容。
