无法使用spring集成和imap空闲重新连接到Outlook MailBox

标签： spring-integration javamail

我正在使用spring集成，当服务器有时保持IDLE时，我会遇到异常。我无法重现以下异常。

Caused by: javax.mail.FolderClosedException: * BYE JavaMail Exception: java.net.SocketException: Connection timed out
    at com.sun.mail.imap.IMAPFolder.handleIdle(IMAPFolder.java:3199)
    at com.sun.mail.imap.IMAPFolder.idle(IMAPFolder.java:3043)

    at org.springframework.integration.mail.ImapIdleChannelAdapter$IdleTask.run(ImapIdleChannelAdapter.java:220)
    ... 10 common frames omitted



The below exeption is thrown from java mail 1.5

Please help me in reproducing this issue and fix for this issue. Thanks

2 个答案:

答案 0 :(得分：0)

如果连接空闲时间过长，服务器将超时连接。您需要每20到30分钟戳一次服务器以保持连接活动，例如，使用Folder.getMessageCount。 （当然，由于各种其他原因，连接仍然可能会中断，所以在任何情况下你都必须准备好处理它。）

答案 1 :(得分：0)

它只是一个警告日志;在此异常之后，适配器将重新连接。

如果要取消日志消息，请将该类别的日志级别降低到ERROR。

修改

除非您更改reconnectDelay ...

，否则它将在失败后10秒重新连接 
@Test
public void testIdleReconnects() throws Exception {
    ImapMailReceiver receiver = spy(new ImapMailReceiver("imap:foo"));
    receiver.setBeanFactory(mock(BeanFactory.class));
    receiver.afterPropertiesSet();
    ImapIdleChannelAdapter adapter = new ImapIdleChannelAdapter(receiver);
    Folder folder = mock(Folder.class);
    willThrow(new FolderClosedException(folder, "test")).given(receiver).waitForNewMessages();
    ThreadPoolTaskScheduler taskScheduler = new ThreadPoolTaskScheduler();
    taskScheduler.initialize();
    adapter.setTaskScheduler(taskScheduler);
    adapter.afterPropertiesSet();
    final CountDownLatch latch = new CountDownLatch(3); << exit test after 3
    adapter.setApplicationEventPublisher(e -> {
        latch.countDown();
    });
    adapter.start();
    assertTrue(latch.await(60, TimeUnit.SECONDS));
}

如果您没有看到与这些类似的日志，则应使用完整配置和日志编辑问题 - 您还应尝试将javamail属性mail.debug设置为true以查看活动。

这就是上述测试为我产生的......

如您所见，我们尝试每10秒重新连接一次。
