帮我写一个java ，jdk8的Exchange邮箱的收件箱收取指定日期的邮件的demo

好的，以下是一个简单的Java 8的Exchange邮箱的收件箱收取指定日期的邮件的示例代码：

import java.util.*;
import javax.mail.*;
import javax.mail.search.*;
import com.sun.mail.imap.*;

public class ExchangeEmailDemo {
    public static void main(String[] args) throws Exception {

        // 设置邮箱账户和密码
        String username = "your_email@your_exchange_server.com";
        String password = "your_password";

        // 创建一个会话
        Properties props = new Properties();
        props.setProperty("mail.store.protocol", "imaps");
        props.setProperty("mail.imaps.host", "your_exchange_server.com");
        props.setProperty("mail.imaps.port", "993");
        Session session = Session.getInstance(props);

        // 连接邮箱
        Store store = session.getStore();
        store.connect(username, password);

        // 获取收件箱
        Folder inbox = store.getFolder("INBOX");
        inbox.open(Folder.READ_ONLY);

        // 设置搜索条件为指定日期
        Calendar cal = Calendar.getInstance();
        cal.set(Calendar.YEAR, 2022);
        cal.set(Calendar.MONTH, Calendar.JANUARY);
        cal.set(Calendar.DAY_OF_MONTH, 1);
        SearchTerm searchTerm = new ReceivedDateTerm(ComparisonTerm.EQ, cal.getTime());

        // 搜索符合条件的邮件
        Message[] messages = inbox.search(searchTerm);

        // 打印搜索结果
        for (int i = 0; i < messages.length; i++) {
            Message message = messages[i];
            System.out.println("Subject: " + message.getSubject());
            System.out.println("From: " + message.getFrom()[0]);
            System.out.println("Sent Date: " + message.getSentDate());
            System.out.println();
        }

        // 关闭邮箱连接
        inbox.close(false);
        store.close();
    }
}

需要注意的是，此示例代码使用JavaMail和Java Activation Framework（JAF）库。如果您尚未安装这些库，请先下载并将它们添加到您的项目中。
