Javamail 使用关键字(多个搜索词)搜索未读邮件

Question

我知道如何使用关键字搜索邮件，我也知道如何搜索未读邮件。但我不知道如何将这两件事结合起来。这是我的代码：

        Properties props = System.getProperties();
        props.setProperty("mail.store.protocol", "imaps");
        try {
            Session session = Session.getDefaultInstance(props, null);
            //GMail connecting
            Store store = session.getStore("imaps");
            store.connect("imap.gmail.com", user, password);
            Folder inbox = store.getFolder("Inbox");
            inbox.open(Folder.READ_WRITE);
            //Enter term to search here
            BodyTerm bodyTerm = new BodyTerm("abcd");
            FlagTerm flagTerm = new FlagTerm(new Flags(Flags.Flag.SEEN), false);
            //can only search with one term at one time
            Message[] foundMessages = inbox.search(bodyTerm);
        }
        catch (MessagingException e) {
            e.printStackTrace();
        }
        catch (IOException e) {
            e.printStackTrace();
        }

Answer 1

根据您的需要使用AndTerm或OrTerm。

你确实读过javadocs，对吧？

Answer 2

您可以使用两个或多个搜索条件，如下所示。我已经给出了两个搜索词的代码，并且可以使用数组为多个搜索词提供代码

 Folder folderInbox = store.getFolder("INBOX");
            folderInbox.open(Folder.READ_WRITE);
            // fetches new messages from server with specific sender
            SearchTerm sender1 = new FromTerm(new InternetAddress("[e-mail]"));
           //fetch only unread messages
            Flags seen = new Flags(Flags.Flag.SEEN);
            FlagTerm unseenFlagTerm = new FlagTerm(seen, false);
            //searching sender
            //combire search tersm
            SearchTerm searchTerm = new AndTerm(unseenFlagTerm,sender1);
        Message[] arrayMessages = folderInbox.search(searchTerm);

在上面的代码中，我将用户特定的 shine.com 作为发件人，并且仅将未读电子邮件作为其他搜索词。
