我在使用带有骆驼的Jackson
JSON库时遇到了麻烦.
例外是：
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>

<cxf.version>2.7.8</cxf.version>
<activemq.version>5.6.0</activemq.version>

<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.
