ActiveMQ连接被拒绝

Question

我试图在我的应用程序中使用activemq ，但在尝试连接到localhost时仍然出现错误：

log4j:WARN No appenders could be found for logger (org.springframework.core.env.StandardEnvironment).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

应该运行一个文件来启动它（活动mq），这是Windows机器上的.bat文件。 当你运行它然后它启动并让你在命令提示符下运行它。

在家里我有一个mac并使用mac等效终端打印：

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]

任何人都可以帮助我让这个东西运行起来吗？

Answer 1

您的应用程序无法连接到activemq。 检查您的activemq是否正在运行并正在侦听localhost 61616。

您可以尝试使用： netstat -a来检查activemq进程是否已启动。 或者尝试使用管理页面检查您是否可以访问actvemq：localhost：8161 / admin / queues.jsp

在Mac上，您将使用以下命令启动您的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

当我使用下面的连接工厂ConnectionFactory factory = new时，我遇到了类似的问题
ActiveMQConnectionFactory("admin","admin","tcp://:61616");

当我将其更改为下面时，它已解决

ConnectionFactory factory = new ActiveMQConnectionFactory("tcp://:61616");

下面显示我的Q大小正在增加.. http://:8161/admin/queues.jsp

我也有类似的问题。 在我的情况下，brokerUrl配置不正确。 所以这是我收到以下错误的方式：

Cause: Error While attempting to add new Connection to the pool: nested exception is javax.jms.JMSException: Could not connect to broker URL : tcp://localhost:61616. Reason: java.net.ConnectException: Connection refused

我按照以下方式解决了问题。

   ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory();

  connectionFactory.setBrokerURL("tcp://hostname:61616");
  connectionFactory.setUserName("admin");
  connectionFactory.setPassword("admin");
