マルチパートパラメータを使用するrestサービスを実行中に、Beanプロパティ 'componentName'に書き込みができないか、無効なセッターメソッドエラーが発生しました

Question

私は自分のプロジェクトでSpring Integrationを使用しています。私はmultipart/formdata入力パラメータを取る休憩サービスを実行しようとしています。私はint-http:outbound-gatewayを使用して休憩サービスを実行しています。以下はコードです

<int:channel id="PQcreateAttachment-Rest-Channel" /> 
    <int:chain input-channel="PQcreateAttachment-Rest-Channel" output-channel="PQcreateAttachment-StoredProcedure-Router" > 

     <int:header-filter header-names="accept-encoding"/>  

     <int:service-activator ref="httpOutboundGatewayHandler" method="buildMultipartHttpOutboundGatewayRequest" /> 

     <int-http:outbound-gateway url-expression="headers.restResourceUrl" 
            http-method-expression="headers.httpMethod" 
            extract-request-payload="true" 
            > 
     </int-http:outbound-gateway> 
     <bean id="headerMapper" class="org.springframework.integration.http.support.DefaultHttpHeaderMapper"> 
     <property name="outboundHeaderNames" value="Content-Type"/> 
    </bean> 

     <int:service-activator ref="msgHandler" method="buildMessageFromExtSysResponse" /> 

    </int:chain> 

上記のコードを実行すると、次のエラーが発生します。

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'headerMapper' defined in file [D:\SIGAWDCS-524\customer-service\csServer\target\test-classes\CustomerService\spring-integration\Jobs\PQCreateAttachment.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'componentName' of bean class [org.springframework.integration.http.support.DefaultHttpHeaderMapper]: Bean property 'componentName' is not writable or has an invalid setter method.

ここで何が間違っているかに関するアイデアはありますか？追加情報が必要な場合はお知らせください。

Answer 1

あなたは<chain>定義の外で

<bean id="headerMapper" class="org.springframework.integration.http.support.DefaultHttpHeaderMapper"> 

を移動する必要があります。

<chain>はanyをサポートしますが、MessageHandlerを生成するものだけです。

一方で私はあなたの応答のために何とかDefaultHttpHeaderMapper ...
