Camel DataFormat Jackson 使用蓝图 XML DSL 引发上下文异常

Question

无论我将数据格式放在 XML DSL 蓝图中的哪个位置，我都会在不同的位置开始出现此错误。如果我删除它，它可以工作，但我当然不能将 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"

            </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，我必须删除属性和流缓存语句才能使其工作。但我需要代理属性。有什么建议么？？？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 已针对 camel-blueprint.xsd 进行验证。 您对名称为 camelContextFactoryBean 的复杂类型感兴趣，其中包含具有固定顺序的可用元素序列。

在此序列中定义的 camelContext 元素的正确顺序是：

• 属性
• 全局选项
• propertyPlaceholder
• 包
• 包扫描
• 上下文扫描
• jmxAgent
• 流缓存
• 导出
• defaultServiceCallConfiguration
• serviceCallConfiguration
• defaultHystrixConfiguration
• hystrix 配置
• 路由构建器
• routeContextRef
• restContextRef
• 线程池配置文件
• 线程池
• 端点
• 数据格式
• 变压器
• 验证器
• redeliveryPolicyProfile
• onException
• 完成时
• 拦截
• 拦截来源
• 拦截SendToEndpoint
• 休息配置
• 休息
• 路线

为了解决您的问题，将所有 endpoint 声明移到 dataFormats 上方。
