使用Jackson JSON库与骆驼的例外

我在使用带有骆驼的Jackson JSON库时遇到了麻烦.
例外是：

FailedToCreateRouteException: Failed to create route... because of Data format 'json-jackson' could not be created. Ensure the data format is valid and the associated Camel component is present on the classpath

这是类路径通知的开始,杰克逊的libs在那里：

<<< camel-maven-plugin:2.9.0:run (default-cli) @ portlistener <<<

--- camel-maven-plugin:2.9.0:run (default-cli) @ portlistener ---
Classpath = [file:/C:/Users/andrew.b-ext/Workspace/portlistener/target/classes/,file:/C:/Users/andrew.b-ext/.m2/repository/org/codehaus/jackson/jackson-asl/1.9.13/jackson-core-asl-1.9.13.jar,file:/C:/Users/andrew.b-ext/.m2/repository/org/codehaus/jackson/jackson-mapper-asl/1.9.13/jackson-mapper-asl-1.9.13.jar,file:/C:/Users/andrew.b-ext/.m2/repository/org/codehaus/jackson/jackson-jaxrs/1.9.13/jackson-jaxrs-1.9.13.jar,...snip...

我的pom有杰克逊：

<properties>
    <camel.version>2.12.2</camel.version>
    <cxf.version>2.7.8</cxf.version>
    <activemq.version>5.6.0</activemq.version>
</properties>

<dependencies>
  <dependency>
     <groupId>org.codehaus.jackson</groupId>
     <artifactId>jackson-core-asl</artifactId>
     <version>1.9.13</version>
  </dependency>
  <dependency>

  <dependency>
     <groupId>org.codehaus.jackson</groupId>
     <artifactId>jackson-jaxrs</artifactId>
     <version>1.9.13</version>
  </dependency>

这是我对Dataformat对象的定义：

<bean id="jsonDataformat" class="org.apache.camel.model.dataformat.JsonDataFormat">
    <property name="unmarshalType" value="java.util.Map" />
    <property name="library" value="Jackson"></property>
</bean>

我尝试将jsonDataformat声明更改为：

<camel:dataFormats>
            <camel:json id="jsonDataformat" library="Jackson"/>
</camel:dataFormats>

当我这样做时,我得到一个不同的错误：

Configuration problem: Cannot locate BeanDefinitionParser for element [dataFormats]

谁能看到我做错了什么？

谢谢,

安德鲁

解决方法

你错过了camel-jackson依赖：

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-jackson</artifactId>
    <version>${camel-version}</version>
</dependency>

这会引入jackson-core-asl和jackson-mapper-asl,但不幸的是杰克森 – 贾克斯.对于后者,您仍然需要在兼容版本中显式依赖.
