Question

我有一个奇怪的例外，这个例外发生在生产环境中的一周之后，偶尔发生。到目前为止，一切都很好。

在我使用imap连接到MS Exchange服务器以读取电子邮件的代码中。这部分代码仍然正常工作。

一旦阅读了电子邮件，它就会存档在子文件夹中。这部分有时会发送异常。

例外是“无法创建新的商店连接”。

在此消息之后，我在跟踪中总是有以下异常：

我觉得奇怪的是，只有当我连接到商店时才会发生这种情况。我仍然可以毫无问题地阅读电子邮件。

这段代码抛出异常：

public void saveMessage(MimeMessage message, String folderName) {
    try {
        Folder folder = message.getFolder();
        folder.open(Folder.READ_WRITE);
        // Mark the message as Delete in its folder
        String messageId = message.getMessageID();
        Message[] messages = folder.getMessages();

似乎是getFolder发送消息。

我无法理解的是，当我尝试访问商店时，为什么会出现SSL异常，而使用相同的uri则没有任何问题来阅读电子邮件。

我有以下配置：

<int:channel id="receiveChannel" datatype="javax.mail.internet.MimeMessage"/>

<int-mail:inbound-channel-adapter id="incomingEmailsAdapter"
    store-uri="${inboundMail.storeUri}"
    channel="receiveChannel"
    should-delete-messages="false"
    should-mark-messages-as-read="true"
    auto-startup="${inboundMail.startup}"
    java-mail-properties="javaMailInboundProperties">
    <int:poller max-messages-per-poll="${inboundMail.nb.poll}" fixed-rate="${inboundMail.nb.rate}"/>
</int-mail:inbound-channel-adapter>

<util:properties id="javaMailInboundProperties">
    <prop key="mail.imap.socketFactory.class">javax.net.ssl.SSLSocketFactory</prop>
    <prop key="mail.imaps.ssl.trust">*</prop>
    <prop key="mail.imap.socketFactory.fallback">false</prop>
    <prop key="mail.store.protocol">imaps</prop>
    <prop key="mail.debug">${inboundMail.debug}</prop>
</util:properties>

<int:service-activator id="serviceActivator" input-channel="receiveChannel" ref="mailService" method="handleMail"/>

使用：

inboundMail.storeUri = imaps：//未知：REDACTED@company.com：993 / inbox

为什么我可以用这个uri阅读电子邮件，我不能用同一个商店打开商店吗？

这个问题每天发生几次，因为一周。

知道它可能来自哪里？
