Camel/Spring在声明ActiveMQ代理时给出错误：“未绑定元素‘broker:broker’的前缀broker”

我正在尝试使用嵌入的camel-activemq代理。当我在Spring文件中包含以下xml时，我会在底部获得更完整的堆栈跟踪错误：

Line 13 in XML document ... is invalid; ... The prefix "broker" for element "broker:broker" is not bound

引用的xml：

<broker:broker useJmx="false" persistent="false" brokerName="localhost">
   <broker:transportConnectors>
      <broker:transportConnector uri="tcp://localhost:61616"/>
   </broker:transportConnectors>
</broker:broker>

我想出来了。最上面的标记缺少一行：xmlns:broker=http://activemq.apache.org/schema/core

您需要指定代理XML命名空间/xsd

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:broker="http://activemq.apache.org/schema/core"
       xsi:schemaLocation="
