我正在尝试启动 ActiveMQ 5.11,我看到了如下的 WARNING:

WARN | Transport Connection to: tcp://127.0.0.1:40890 failed: java.io.EOFException

我的activemq.xml如下:

<transportConnectors>
<transportConnector name="openwire" uri="tcp://0.0.0.0:${JMS_PORT}" />
<transportConnector name="stomp" uri="stomp://0.0.0.0:${JMS_STOMP_PORT}"/>
<transportConnector name="ssl" uri="ssl://0.0.0.0:${JMS_SSL_PORT}"/>
</transportConnectors>

<sslContext>
<sslContext
keyStore="file:${JMS_KEY_STORE}"
keyStorePassword="${JMS_KEY_STORE_PASSWORD}"
trustStore="file:${JMS_TRUST_STORE}"
trustStorePassword="${JMS_TRUST_STORE_PASSWORD}"
/>
</sslContext>

<networkConnectors>
<networkConnector

uri="static://(${JMS_X_SITE_CSV_URL})?wireFormat=ssl&amp;wireFormat.maxInactivityDuration=30000"
dynamicOnly="true"
suppressDuplicateQueueSubscriptions = "true"
networkTTL="1"
/>
</networkConnectors>

这是完整的控制台日志:

有人能告诉我为什么会抛出这些异常吗?如果有人需要更深入地了解,我可以提供整个日志文件。

最佳答案

这个警告是因为networkConnector的方式工作和配置。我已将此发布在 ActiveMQ users mailing list 上.

当使用 networkConnector 时,ActiveMQ 会尝试连接到已配置的代理。在我的例子中,我试图 self 连接到代理,这就是它拒绝连接的原因。 Tim 在社区中也指出了同样的问题。

I've never tried configuring a broker with a static networkConnector connected to itself (why would I, it's a useless configuration), but it wouldn't surprise me if the broker rejected that self-connection, which could result in the EOFException you saw. It's also possible that there's something wrong with your SSL configuration as you suggested; there's no good way in a mailing list discussion to check whether your truststore trusts your keystore and the certs are being presented properly since that's all about the binary content and you shouldn't be sharing that publicly, but you could test the SSL configuration by setting up two brokers (in a test environment) that each have their JMS_X_SITE_CSV_URL pointed at each other. If that configuration gives you EOFExceptions, then switch to using the tcp transport and see what happens. If you get errors with the ssl transport but not the tcp one, there's a good chance it's something wrong with your keys.

As far as the current configuration (where you have a broker whose only networkConnection is a static:ssl: one to itself), it's not a useful configuration (having a networkConnector to yourself serves no purpose), and you proved early on in this discussion that removing it removes the WARN log line that you're concerned about. So I disagree with your statement that "I feel the configuration still seems fine." Either switch to something that serves the purpose you said you're trying to achieve (like the discovery: transport instead of the static: transport, or like listing your cross-site servers if you're going to continue using the static: transport) or take it out and eliminate the WARN line.

因此,如果 networkConnector 是单个代理系统,则它基本上没有用。它在多代理部署中更有意义,然后配置所有代理,除了每个代理上的 self 。

为了仍然使 networkConnector 配置在单一代理部署中工作,我必须设置的值是 - url="static://(ssl://divinedragonbox:7031) ...”(主机名而不是 IP 地址或 localhost)。这消除了出现的 WARNING
