当 ActiveMQ 启动时警告为 java.io.EOFException
WARNING as java.io.EOFException when ActiveMQ starts
我正在尝试启动 ActiveMQ 5.11，我看到 WARNING 如下：
WARN | Transport Connection to: tcp://127.0.0.1:40890 failed: java.io.EOFException
我的activemq.xml如下：

Can somebody tell me why are these exceptions thrown?
如果有人需要更深入的了解，我可以提供整个日志文件。
这些 EOFExceptions 表示客户端连接到代理，然后在没有完全关闭连接的情况下断开连接。典型的罪魁祸首包括 tcp/ip 监控代理和错误编码的客户端。
所以，我终于找到了这个问题的根本原因。这个 WARNING 来是因为 networkConnector works and configured. I had posted this on the activemq community here - http://activemq.2283324.n4.nabble.com/java-io-EOFException-when-ActiveMQ-starts-td4717598.html
当使用 networkConnector 时，activemq 尝试连接到配置的代理。就我而言，我试图自行连接到代理，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.
所以，networkConnector如果是单一经纪商系统，本质上是没有用的。在多代理部署中更有意义，然后配置所有代理，除了每个代理上的自我。
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）。这摆脱了 WARNING 来了。
我正在尝试启动 ActiveMQ 5.11，我看到 WARNING 如下：
WARN | Transport Connection to: tcp://127.0.0.1:40890 failed: java.io.EOFException
我的activemq.xml如下：
<transportConnectors>

<transportConnector name="stomp" uri="stomp://0.0.0.0:${JMS_STOMP_PORT}"/>

Can somebody tell me why are these exceptions thrown?
如果有人需要更深入的了解，我可以提供整个日志文件。
这些 EOFExceptions 表示客户端连接到代理，然后在没有完全关闭连接的情况下断开连接。典型的罪魁祸首包括 tcp/ip 监控代理和错误编码的客户端。
所以，我终于找到了这个问题的根本原因。这个 WARNING 来是因为 networkConnector works and configured. I had posted this on the activemq community here - http://activemq.2283324.n4.nabble.com/java-io-EOFException-when-ActiveMQ-starts-td4717598.html
当使用 networkConnector 时，activemq 尝试连接到配置的代理。就我而言，我试图自行连接到代理，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.
所以，networkConnector如果是单一经纪商系统，本质上是没有用的。在多代理部署中更有意义，然后配置所有代理，除了每个代理上的自我。
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）。这摆脱了 WARNING 来了。
