【中文标题】ActiveMQ 启动时警告为 java.io.EOFException【英文标题】：WARNING as java.io.EOFException when ActiveMQ starts 【发布时间】：2017-02-16 08:51:20 【问题描述】：

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="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 
        name="host1 and host2" 
        uri="static://($JMS_X_SITE_CSV_URL)?wireFormat=ssl&amp;wireFormat.maxInactivityDuration=30000"
        dynamicOnly="true"
        suppressDuplicateQueueSubscriptions = "true"
        networkTTL="1"
    />
</networkConnectors>

这是整个控制台日志。

谁能告诉我为什么会抛出这些异常？

如果有人需要更深入的了解，我可以提供整个日志文件。

【问题讨论】：

【参考方案1】：

所以，我终于找到了这个问题的根本原因。这个WARNING 的出现是因为networkConnector 的工作方式和配置方式。我在这里的 activemq 社区上发布了这个 - http://activemq.2283324.n4.nabble.com/java-io-EOFException-when-ActiveMQ-starts-td4717598.html

当使用networkConnector 时，activemq 会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 在社区中也指出了这一点。

我从未尝试使用静态 networkConnector 配置代理连接到自身（为什么我会，这是一个无用的配置），但是如果经纪人拒绝了这种自我连接，我不会感到惊讶，这可能会导致您看到的 EOFException。也是可以的您的 SSL 配置有问题建议；在邮件列表讨论中没有很好的方法来检查您的信任库是否信任您的密钥库并且证书正在正确呈现，因为这都是关于二进制内容的，你不应该公开分享，但你可以测试 SSL 通过设置两个代理（在测试环境中）进行配置每个都有自己的 JMS_X_SITE_CSV_URL 指向对方。如果说配置给你EOFExceptions，然后切换到使用tcp 运输，看看会发生什么。如果您遇到 ssl 错误运输，但不是 tcp 的，很有可能是某种东西你的钥匙有问题。

就当前配置而言（您有一个代理，其只有 networkConnection 是一个静态的：ssl：一个到它自己），它不是一个有用的配置（给自己一个 networkConnector 没有用目的），并且您在本次讨论的早期证明将其删除删除您关心的 WARN 日志行。所以我不同意用你的说法“我觉得配置看起来还不错”。要么切换到符合您所说的目的的东西试图实现（如发现：传输而不是静态：传输，或者喜欢列出你的跨站点服务器，如果你是将继续使用静态：运输）或将其取出并删除 WARN 行。

因此，networkConnector 如果是单一代理系统，则基本上没有用处。在多代理部署中更有意义，然后配置所有代理，每个代理上的自我除外。

要使networkConnector 配置仍能在单代理部署中工作，我必须设置的值是-url="static://(ssl://divinedragonbox:7031)..."（主机名而不是IP 地址或localhost）。这样就摆脱了WARNING。

【讨论】：

【参考方案2】：

那些 EOFExceptions 表示客户端连接到代理，然后断开连接而没有完全关闭连接。典型的罪魁祸首包括 tcp/ip 监控代理和错误编码的客户端。

【讨论】：

但是，我没有运行任何客户端。我一启动 ActiveMQ 就会收到此警告消息。它内部是否有代理本身的客户？
