java - 如何在 Java、Spring 和 Apache Camel 中定义 url

Question

在 Apache Camel 中，我想将 XML 文件内容发送到 jms 队列。我的 Camel 代码中有:

 .to("jms:accounting");

所以我需要在我的camel-context.xml中定义jms。

我有

 xmlns:broker="http://activemq.apache.org/schema/core"

然后

<!-- ActiveMQ Broker -->
<broker:broker useJmx="false" persistent="false" brokerName="localhost">
    <broker:transportConnectors>
        <broker:transportConnector name="tcp" uri="tcp://localhost:61616"/>
    </broker:transportConnectors>
</broker:broker>

<!-- JMS que -->
<bean id="jms" class="org.apache.camel.component.jms.JmsComponent">
    <property name="connectionFactory">
        <bean class="org.apache.activemq.ActiveMQConnectionFactory">
            <property name="brokerURL" value="tcp://localhost:61616"/>
        </bean>
    </property>
</bean>

当我运行该项目时，我收到此错误:

[ERROR] Failed to execute goal org.apache.camel:camel-maven-plugin:2.20.0:run (default-cli) on project 08-xml-to-jms: null: MojoExecutionException: InvocationTargetException: Line 22 in XML document from file [/IdeaProjects/training/target/classes/META-INF/spring/camel-contxt.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 22; columnNumber: 77; cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'broker:broker'. -> [Help 1]

更改部分

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

至

 <broker xmlns="http://activemq.apache.org/schema/core" useJmx="false" persistent="false" brokerName="localhost>
    <transportConnectors>
      <transportConnector name="tcp" uri="tcp://localhost:61616"/>
    </transportConnectors>
  </broker>
