Camel DataFormat Jackson使用蓝图XML DSL抛出上下文异常

Question

无论我将数据格式放在XML DSL蓝图中，我都会在不同的地方出现此错误。如果我删除它，它可以工作但当然我不能将JSON转换为POJO。 ???任何帮助或告诉我我做错了什么，我错过了什么。谢谢！

错误

Unable to start blueprint container for bundle passthrumt1.core/1.0.1.SNAPSHOT
Caused by: org.xml.sax.SAXParseException: cvc-complex-type.2.4.a: Invalid content was found starting with element 'endpoint'. One of '{"http://camel.apache.org/schema/blueprint":redeliveryPolicyProfile, "http://camel.apache.org/schema/blueprint":onException, "http://camel.apache.org/schema/blueprint":onCompletion, "http://camel.apache.org/schema/blueprint":intercept, "http://camel.apache.org/schema/blueprint":interceptFrom, "http://camel.apache.org/schema/blueprint":interceptSendToEndpoint, "http://camel.apache.org/schema/blueprint":restConfiguration, "http://camel.apache.org/schema/blueprint":rest, "http://camel.apache.org/schema/blueprint":route}' is expected.

XML DSL

   <camelContext     
      id="com.passthru.coreCamelContext"
      trace="true"
      xmlns="http://camel.apache.org/schema/blueprint"
      allowUseOriginalMessage="false"
      streamCache="true"
      errorHandlerRef="deadLetterErrorHandler" >

    <properties>
        <property key="http.proxyHost" value="PITC-Zscaler-Americas.proxy.corporate.com"/>
        <property key="http.proxyPort" value="80"/>
    </properties>

    <streamCaching  id="CacheConfig" 
                    spoolUsedHeapMemoryThreshold="70" 
                    anySpoolRules="true"/>
<!--  -->
    <dataFormats>

            </json>
    </dataFormats>

    <endpoint id="predixConsumer" uri="direct:preConsumer" />
    <endpoint id="predixProducer" uri="direct:preProducer" />
    <endpoint id="getToken" uri="direct:getToken" />

      <onException>
        <exception>com.passthru.dataservice.PDXDataServiceInvalidDataException</exception>
        <redeliveryPolicy maximumRedeliveries="3" />
        <handled>
          <constant>true</constant>
        </handled>
        <log
          message="Invalid Data From Data Service"
          loggingLevel="ERROR" />
        <setBody>
          <simple>${body.toString}</simple>
        </setBody>
        <to uri="file:{{errorArchive}}" />
      </onException>

如果我将数据格式放在属性之上，它会抱怨，我必须删除属性和streamcache语句才能使它工作。但我需要代理属性。有什么建议？？？再次感谢

如果

<camelContext     
  id="com.ge.digital.passthru.coreCamelContext"
  trace="true"
  xmlns="http://camel.apache.org/schema/blueprint"
  allowUseOriginalMessage="false"
  streamCache="true"
  errorHandlerRef="deadLetterErrorHandler" >
<dataFormats>
    <json id="Json2Pojo" library="Jackson" unmarshalTypeName="com.passthru.core.entities.TokenEntities"/>
</dataFormats>
<properties>
    <property key="http.proxyHost" value="PITC-Zscaler-Americas-Cincinnati3PR.proxy.corporate.com"/>
    <property key="http.proxyPort" value="80"/>
</properties>

我明白了

Caused by: org.xml.sax.SAXParseException: cvc-complex-type.2.4.a: Invalid content was found starting with element 'properties'. One of '{"http://camel.apache.org/schema/blueprint":redeliveryPolicyProfile, "http://camel.apache.org/schema/blueprint":onException, "http://camel.apache.org/schema/blueprint":onCompletion, "http://camel.apache.org/schema/blueprint":intercept, "http://camel.apache.org/schema/blueprint":interceptFrom, "http://camel.apache.org/schema/blueprint":interceptSendToEndpoint, "http://camel.apache.org/schema/blueprint":restConfiguration, "http://camel.apache.org/schema/blueprint":rest, "http://camel.apache.org/schema/blueprint":route}' is expected.

我错过了什么？

Answer 1

Camel蓝图XML针对camel-blueprint.xsd进行了验证。 您感兴趣的是名为camelContextFactoryBean的复杂类型，其中包含具有固定顺序的可用元素序列。

此序列中定义的camelContext元素的正确顺序为：

• 属性
• globalOptions
• propertyPlaceholder
• 包
• packageScan
• contextScan
• jmxAgent
• streamCaching
• 出口
• defaultServiceCallConfiguration
• serviceCallConfiguration
• defaultHystrixConfiguration
• hystrixConfiguration
• routeBuilder
• routeContextRef
• restContextRef
• threadPoolProfile
• 的线程池
• 端点
• dataFormats
• 变压器
• 验证
• redeliveryPolicyProfile
• onException的
• onCompletion
• 截距
• interceptFrom
• interceptSendToEndpoint
• restConfiguration
• 其余
• 路线

要解决您的问题，请移动endpoint上方的所有dataFormats声明。
