Karafにバンドル（camelを使用）を配置すると、以下の例外が表示されます。以下の例外は、バンドルが開始された場合にのみ発生します。その後、すべて正常に動作します。例外は私たちの機能に影響を与えていないようです。この問題は、camel 2.16.1（servicemix 6.1.0にデプロイされている）とcamel 2.16.3（デプロイされているservicemix 7.0.0M2）の両方に発生しています。循環依存のためにラクダの開始時にエラーが発生しました
私のblueprintは3つのファイルに分割されています。それらの単純化されたバージョンを以下に示す： -
バンドル開始時にこの例外がなぜ発生するのか教えてください。下のスタックトレースからは、循環依存性のために表示されます。どうすればこの問題を回避できますか？

EDIT - 以下に示すようjsonRPCProcessorがmyTemplateを使用しているため誤差があると思われる： -
<bean id="jsonRPCProcessor" class="com.j1.orchestratorservice.basecomponent.processor.JSONRPCProcessor">
<argument ref="myTemplate" />
<argument>
<map>
<!-- Product End Points -->
<entry key="Product.createProducts" value-ref="createProductsWFInfo" />
</map>
</argument>
<argument ref="exceptionHandler" />
</bean>
myTemplateは、以下に示すように順番にjsonRPCProcessorを使用しているcamelContextで定義されているのに対し： -
<camelContext xmlns="http://camel.apache.org/schema/blueprint"
useMDCLogging="true">
<template id="myTemplate" />
<route id="orchestrator-service-route">
<from uri="jetty:http://0.0.0.0:8888/orchestratorservice" />
<process ref="jsonRPCProcessor" />
</route>
<route id="file-upload-service-route">
<from
uri="jetty:http://0.0.0.0:8889/fileuploadservice?enableMultipartFilter=true" />
<process ref="fileUploadProcessor" />
</route>
...
</camelContext>
私は私のカスタムプロセッサでこのlinkに記載されている通りproducer。誰かが私のカスタムjsonRPCProcessorにproducerを設定する別の方法を提案して、それが循環依存にならないようにすることはできますか？
3つのファイルに分割した理由はありますか？どうして？ –
ええ、それは巨大になっていた。ここで理解しやすくなるように、私は非常に小さな部分を追加しました。 – tuk
私が言っていることは、苦情は循環依存であるため、設定ファイルの内容が互いに参照しているということです。つまり、それは私が意味することです、おそらくすべてを1つに入れて、3つに分割して動作させるようにします。 –
