我正在尝试在我的应用程序中使用 activemq，但是当我尝试连接到 localhost 时总是出现错误:

log4j:WARN Please initialize the log4j system properly.

有一个应该运行的文件来启动它( Activity mq)，这是 Windows 机器上的 .bat 文件。当您运行它时，它就会启动，您可以让它在命令提示符下继续运行。

在家里，我有一台 mac，使用 ma​​c 等价物，终端只打印:

Last login: Mon Oct 29 19:57:15 on ttys000
(null):~ rickilambert$ /Users/rickilambert/Downloads/apache-activemq-5.7.0/bin/macosx/activemq ; exit;
Usage: /Users/rickilambert/Downloads/apache-activemq-5.7.0/bin/macosx/activemq { console | start | stop | restart | status | dump }
logout

[Process completed]

谁能帮我启动并运行这个东西？

您的应用程序无法连接到 activemq。检查您的 activemq 是否正在运行并在本地主机 61616 上监听。

您可以尝试使用:netstat -a 来检查activemq 进程是否已经启动。或者尝试检查您是否可以使用管理页面访问您的 actvemq:localhost:8161/admin/queues.jsp

在 mac 上，您将使用以下命令启动 activemq:

$ACTMQ_HOME/bin/activemq start 

或者如果您的配置文件 (activemq.xml) 位于另一个位置，您可以使用:

$ACTMQ_HOME/bin/activemq start xbean:file:${location_of_your_config_file}

在您的情况下，可执行文件位于:bin/macosx/activemq 因此您需要使用:$ACTMQ_HOME/bin/macosx/activemq start
