我正在尝试使用 GreenMail 作为样机邮件服务器进行单元测试。它的工作是等待 IMAP/POP3 请求并发送虚拟邮件，但我无法让它工作。

public class EMailMonitoringTest {
private static final String USER_PASSWORD = "test";
private static final String USER_NAME = "jDownloaderTestUser";
private static final String EMAIL_USER_ADDRESS = "jdtest@localhost";
private static final String EMAIL_TO = "someone@localhost.com";
private static final String EMAIL_SUBJECT = "Test E-Mail";
private static final String EMAIL_TEXT = "This is a test e-mail.";
private static final String LOCALHOST = "127.0.0.1";
private GreenMail mailServer;

@Before
public void setUp() {
    mailServer = new GreenMail(ServerSetupTest.ALL);
    mailServer.start();
}

@After
public void tearDown() {
    mailServer.stop();
}

@Test
public void getMails() throws AddressException, MessagingException, FolderException, UserException, IOException {
    // create user on mail server
    GreenMailUser user = mailServer.setUser(EMAIL_USER_ADDRESS, USER_NAME, USER_PASSWORD);

    // create an e-mail message using javax.mail ..
    MimeMessage message = new MimeMessage((Session) null);
    message.setFrom(new InternetAddress(EMAIL_TO));
    message.addRecipient(Message.RecipientType.TO, new InternetAddress(EMAIL_USER_ADDRESS));
    message.setSubject(EMAIL_SUBJECT);
    message.setText(EMAIL_TEXT);

    // use greenmail to store the message
    user.deliver(message);

    // check received messages
    Message[] messages = mailServer.getReceivedMessages();
    for (Message m : messages) {
        System.out.println("*** Class: " + m.getClass() + " ***");
        System.out.println("From: " + m.getFrom()[0]);
        System.out.println("To: " + m.getRecipients(Message.RecipientType.TO)[0]);
        System.out.println("Subject: " + m.getSubject());
        System.out.println("Content: " + m.getContent());
    }

这里没问题，到目前为止的输出是这样的：

** 类：类 javax.mail.internet.MimeMessage **

来自：某人@localhost.com

收件人：jdtest@localhost

主题：测试电子邮件

内容：这是一封测试邮件。

之后，我尝试从 GreenMail IMAP 服务器获取邮件：

    // fetch the e-mail via imap using javax.mail ..
    Properties props = new Properties();
    Session session = Session.getInstance(props);
    URLName urlName = new URLName("imap", LOCALHOST,
    ServerSetupTest.IMAP.getPort(), null, user.getLogin(),
    user.getPassword());
    Store store = session.getStore(urlName);
    store.connect();

    Folder folder = store.getFolder("INBOX");
    folder.open(Folder.READ_ONLY);
    messages = folder.getMessages();
    System.out.println("Size of Messages: " + messages.length);
    for (Message m : messages) {
        System.out.println("** Class: " + m.getClass() + " **");
        System.out.println("From: " + m.getFrom()[0].toString());
        System.out.println("To: " + m.getRecipients(Message.RecipientType.TO)[0].toString());
        System.out.println("Subject: " + m.getSubject().toString());
        System.out.println("Content: " + m.getContent().toString());
    }

我的奖励是

消息大小：1

** 类：类 com.sun.mail.imap.IMAPMessage **

和一个 FolderClosedException：

尝试访问 folder.getMessage(0) 只会导致 IndexOutOfBoundsException，但在数组中存储了一个 IMAPMessage 类的消息。有人知道这件事吗？

啊，是的，我尝试了hashCode上的示例，但它们也因同样的原因而失败......访问接收到的 IMAP 消息的属性时出现 FolderClosedException......

感激地接受任何提示。

使用 IMAP 时，您配置了 LOCALHOST，但在启动/创建 GreenMail 时从未告诉 GreenMail 使用 LOCALHOST。

使用 GreenMail 服务器ServerSetupTest.IMAP.getBindAddress()的绑定地址而不是LOCALHOST：

// fetch the e-mail via imap using javax.mail ..
// Hint: Create session via GreenMailUtil
Session session = GreenMailUtil.getSession(ServerSetupTest.IMAP);
// Use configured host address instead of supplying a 
URLName urlName = new URLName("imap", ServerSetupTest.IMAP.getBindAddress(),
   ServerSetupTest.IMAP.getPort(), null, user.getLogin(),
   user.getPassword());
Store store = session.getStore(urlName);
store.connect();`
