我使用 JBoss Fuse（jboss-fuse-6.1.0.redhat-379），它预装了与Redhat的Camel功能一起安装的软件包。
根据建议，我们选择使用Blueprint DSL进行配置。我的配置如下：
<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:camel="http://camel.apache.org/schema/blueprint"
xmlns:cxf="http://camel.apache.org/schema/blueprint/cxf" xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.1.0"
xsi:schemaLocation="

</cm:default-properties>
</cm:property-placeholder>
<cxf:rsServer id="rsServer" address="http://localhost:8183/copi"
serviceClass="com.karthik.services.InboxRestService"
loggingFeatureEnabled="true" />
<cxf:rsServer id="rsServerDup" address="http://localhost:8183/copi2"
serviceClass="com.karthik.services.InboxRestService"
loggingFeatureEnabled="true" />
<camelContext id="inboxServiceRouterContext"
xmlns="http://camel.apache.org/schema/blueprint">
<route id="inboxRoute">
<from uri="cxfrs:bean:rsServer?bindingStyle=SimpleConsumer" />
<to uri="direct:inboxService" />
</route>
<route id="inboxRouteDup">
<from uri="cxfrs:bean:rsServerDup" />
<to uri="direct:inboxService" />
</route>
<route id="inboxServiceRoute">
<from uri="direct:inboxService" />
<to uri="bean:inboxService?method=updateCompletedTask" />
<marshal ref="jsonDataformat" />
</route>
</camelContext>
<bean id="inboxService" class="com.karthik.services.InboxService" />
<bean id="jsonDataformat" class="org.apache.camel.model.dataformat.JsonDataFormat">
<property name="unmarshalType" value="com.karthik.bo.Task" />
<property name="library" value="Jackson"></property>
</bean>
</blueprint>
请注意我添加了Jackson库。 在安装我的功能时，我会遇到以下异常。
Failed to create route inboxServiceRoute at: >>> Marshal[ref:jsonDataformat] <<< in route: Route(inboxServiceRoute)[[From[direct:inboxService]] -> [To[... because of Data format 'json-jackson' could not be created. Ensure that the data format is valid and the associated Camel component is present on the classpath
我在pom.xml中定义了以下依赖项

我该如何解决这个问题？具有讽刺意味的是，这种情况已经存在了一段时间，并开始突然抱怨......
答案 0 :(得分：0)
我必须同意 @Claus Ibsen 对驼峰杰克逊 的功能安装的评论。虽然我已经安装了，但jBoss Fuse有些不对劲。我不得不删除'data'文件夹，不得不进行安装。到目前为止我还没有遇到任何问题。所以，我想这应该是它。
谢谢@Claus Ibsen。
