Question

以下是我的用于pop3连接的spring配置bean，

    @Bean
    public IntegrationFlow mailListener() {
        return IntegrationFlows.from(Mail.pop3InboundAdapter("pop3://sample.test:Sample2test_1@xxx.xx.x.xx/INBOX")
                 .shouldDeleteMessages(true).get(), 
                 e -> e.poller(Pollers.fixedRate(5000).maxMessagesPerPoll(1)))
            .<Message>handle((payload, header) -> logMail(payload))
            .get();
    }

还仔细检查了看起来不错的凭据。得到以下异常，

2018-06-22 19：27：54.351错误2092 --- [询问调度程序2] o.s.integration.handler.LoggingHandler： org.springframework.messaging.MessagingException：发生故障在轮询邮件时；嵌套异常为 javax.mail.AuthenticationFailedException：授权在处失败 org.springframework.integration.mail.MailReceivingMessageSource.receive（MailReceivingMessageSource.java:131）在 org.springframework.integration.endpoint.SourcePollingChannelAdapter.receiveMessage（SourcePollingChannelAdapter.java:224）在 org.springframework.integration.endpoint.AbstractPollingEndpoint.doPoll（AbstractPollingEndpoint.java:245）在 org.springframework.integration.endpoint.AbstractPollingEndpoint.access $ 000（AbstractPollingEndpoint.java:58）在 org.springframework.integration.endpoint.AbstractPollingEndpoint $ 1.call（AbstractPollingEndpoint.java:190）在 org.springframework.integration.endpoint.AbstractPollingEndpoint $ 1.call（AbstractPollingEndpoint.java:186）在 org.springframework.integration.endpoint.AbstractPollingEndpoint $ Poller $ 1.run（AbstractPollingEndpoint.java:353）在 org.springframework.integration.util.ErrorHandlingTaskExecutor $ 1.run（ErrorHandlingTaskExecutor.java:55）在 org.springframework.core.task.SyncTaskExecutor.execute（SyncTaskExecutor.java:50）在 org.springframework.integration.util.ErrorHandlingTaskExecutor.execute（ErrorHandlingTaskExecutor.java:51）在 org.springframework.integration.endpoint.AbstractPollingEndpoint $ Poller.run（AbstractPollingEndpoint.java:344）在 org.springframework.scheduling.support.DelegatingErrorHandlingRunnable.run（DelegatingErrorHandlingRunnable.java:54）在 org.springframework.scheduling.concurrent.ReschedulingRunnable.run（ReschedulingRunnable.java:81）在java.util.concurrent.Executors $ RunnableAdapter.call（未知源）位于java.util.concurrent.FutureTask.run（未知源）位于 java.util.concurrent.ScheduledThreadPoolExecutor $ ScheduledFutureTask.access $ 201（未知来源） java.util.concurrent.ScheduledThreadPoolExecutor $ ScheduledFutureTask.run（未知源）在java.util.concurrent.ThreadPoolExecutor.runWorker（未知源），位于java.util.concurrent.ThreadPoolExecutor $ Worker.run（未知源：java.lang.Thread.run（未知源），由以下原因引起： javax.mail.AuthenticationFailedException：授权在处失败 com.sun.mail.pop3.POP3Store.protocolConnect（POP3Store.java:208）位于 javax.mail.Service.connect（Service.java:295）在 javax.mail.Service.connect（Service.java:176）在 javax.mail.Service.connect（Service.java:125）在 org.springframework.integration.mail.AbstractMailReceiver.connectStoreIfNecessary（AbstractMailReceiver.java:286）在 org.springframework.integration.mail.AbstractMailReceiver.openFolder（AbstractMailReceiver.java:293）在 org.springframework.integration.mail.AbstractMailReceiver.receive（AbstractMailReceiver.java:319）在 org.springframework.integration.mail.MailReceivingMessageSource.receive（MailReceivingMessageSource.java:112） ...还有19个

Answer 1

有这样一个选项：

/**
 * The Java Mail properties.
 * @param javaMailProperties the javaMailProperties.
 * @return the spec.
 * @see AbstractMailReceiver#setJavaMailProperties(Properties)
 */
public S javaMailProperties(Properties javaMailProperties) {

您可以在此处mail.debug = true进行指定，以跟踪交互过程中邮件协议的状况。

更新

我们在您的日志中有此记录

DEBUG POP3: connecting to host "172.16.1.45", port 995, isSSL false
19:54:46.746 [task-scheduler-1] DEBUG org.springframework.beans.factory.support.DefaultListableBeanFactory - Returning cached instance of singleton bean 'errorChannel'
19:54:46.753 [task-scheduler-1] DEBUG org.springframework.integration.channel.PublishSubscribeChannel - preSend on channel 'errorChannel', message: ErrorMessage [payload=org.springframework.messaging.MessagingException: failure occurred while polling for mail; nested exception is javax.mail.MessagingException: Connect failed;
  nested exception is:

因此，它不能仅连接到172.16.1.45:995。还没有身份验证握手。
