本文介绍了杰克逊使用JSON库骆驼异常的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我使用的是杰克逊JSON库般地遇到了麻烦。
唯一的例外是：
FailedToCreateRouteException：无法创建航线......因为数据格式JSON-杰克逊的无法创建。确保数据格式是有效的和相关的骆驼组成部分是在类路径present
下面是类路径的通知之初即杰克逊库是否有：
＆LT;＆LT;＆LT;骆驼Maven的插件：2.9.0：运行（默认CLI）@ portlistener＆LT;＆LT;＆LT;---骆驼Maven的插件：2.9.0：运行（默认CLI）@ portlistener ---

＆LT;属性名=库VALUE =禅师＆GT;＆LT; /性＆gt;
＆LT; /豆＆GT;
我试图改变jsonDataformat声明：
＆LT;骆驼：dataFormats＆GT;
＆LT;骆驼：JSON ID =jsonDataformat库=禅师/＆GT;
＆LT; /骆驼：dataFormats＆GT;
当我这样做，我得到一个不同的错误：
配置问题：找不到BeanDefinitionParser的元素[dataFormats]
有人能看到我在做什么错？
谢谢，

解决方案
您缺少骆驼 - 杰克逊依赖性：
＆LT;＆依赖性GT;
＆LT;＆的groupId GT; org.apache.camel＆LT; /的groupId＆GT;
＆LT;＆的artifactId GT;骆驼杰克逊＆LT; / artifactId的＆GT;
＆LT;＆版GT; $ {骆驼版本}＆LT; /版本＆GT;
＆LT; /依赖性＆GT;
这拉杰克逊核心-ASL和杰克逊映射器-ASL，但不幸的是没有杰克逊JAXRS。对于后者，你仍然需要一个兼容版本的显式依赖性。
I am having trouble using the Jackson JSON library with camel.The exception is:
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
Here is the beginning of classpath notice that the Jackson libs are there:
<<< 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...
My pom has Jackson:

Here is my definition of the Dataformat object:
<bean id="jsonDataformat" class="org.apache.camel.model.dataformat.JsonDataFormat">
<property name="unmarshalType" value="java.util.Map" />
<property name="library" value="Jackson"></property>
</bean>
I tried changing the jsonDataformat declaration to:
<camel:dataFormats>
<camel:json id="jsonDataformat" library="Jackson"/>
</camel:dataFormats>
When I do that I get a different error:
Configuration problem: Cannot locate BeanDefinitionParser for element [dataFormats]
Can anyone see what I'm doing wrong?

解决方案
You are missing the camel-jackson dependency:
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-jackson</artifactId>
<version>${camel-version}</version>
</dependency>
This pulls in jackson-core-asl and jackson-mapper-asl, but unfortunately not jackson-jaxrs. For the latter you still need an explicit dependency in a compatible version.
