Spring Batchの.XML設定ファイルにservice-activatorを追加しようとしています。これは、変圧器メソッド：FileMessageToJobRequestTransformerでrequires-reply = falseを設定しています。ここでSpringバッチ：service-activatorの設定
はXMLです：
<int:transformer id="fileMessageToJobRequestTransformer"
input-channel="inboundFileChannel"
output-channel="outboundJobRequestChannel"
method="transform" >
<bean class="com.distributedfinance.mbi.bai.transformer.FileMessageToJobRequestTransformer">
<property name="job" ref="baiParseJob"/>
<property name="fileParameterName" value="input.file.url"/>
</bean>
<int:poller fixed-rate="1000"/>
</int:transformer>
<int:service-activator requires-reply="false" input-channel="inboundFileChannel" output-channel="outboundJobRequestChannel" ref="fileMessageToJobRequestTransformer"> </int:service-activator>
ここでスタックトレースです：

を使用し、私は私の変圧器に「ロジックをスキップ」を追加 - ファイルが既に処理されている場合はnullを返しますfileMessageToJobRequestTransformerを。変圧器からnullを返すときに例外が発生したので、サービスアクチベータにrequires-reply = "false"を追加しようとしました。トランスフォーマーがnullを返すように、これをどのように構成しますか？ありがとう！ – dbl001
次に、トランスフォーマーではなく、サービスアクティベータとしてBeanを呼び出すだけです。私の編集を参照してください。 –
それは助けた！注釈（現在の "@Transformer"）も変更する必要があります（上記のUPDATEを参照）。別の質問（元の質問の接線） - 私はJobInstanceAlreadyCompleteExceptionを正しくキャッチしていますか（動作していないようです）。 – dbl001
