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

Question

无论我将数据格式放在 XML DSL 蓝图中的哪个位置，我都会在不同的地方开始出现此错误。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'.

XML DSL

      trace="true"

        <property key="http.proxyPort" value="80"/>
    </properties>

    <streamCaching  id="CacheConfig"

            </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 已根据 camel-blueprint.xsd 进行验证。您对名称为 camelContextFactoryBean 的复杂类型感兴趣，它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
属性占位符
套餐
packageScan
上下文扫描
jmxAgent
流缓存
导出
默认服务调用配置
服务调用配置
默认Hystrix配置
hystrix配置
路由生成器
routeContextRef
restContextRef
线程池配置文件
线程池
端点
数据格式
变形金刚
验证者
redeliveryPolicyProfile
onException
完成
拦截
截取自
拦截发送端点
restConfiguration
休息
路线

要解决您的问题，请将所有 endpoint 声明移至 dataFormats 上方。
