我无法在 .xmpp 队列中发送消息activemq。我得到以下示例。根据文档，我下载了 wstx jar 并放在activemq/lib/optional文件夹中。

我得到以下异常：

你需要给你的maven pom.xml添加activemq-xmpp依赖

  <dependency>
<groupId>org.apache.activemq</groupId>
<artifactId>activemq-xmpp</artifactId>
<version>5.8.0</version>
 </dependency>

如果您不使用 maven ，请将activemq-xmpp.jar与所有其他 jars 添加到您的 /lib
