我说这个设计有点奇怪。 ExpressionEvaluatingRequestHandlerAdvice是<request-handler-advice-chain>作为<service-activator>的子元素：

<file:outbound-channel-adapter channel="appendToFileChannel"
                               filename-generator-expression="headers.file_name"
                               mode="APPEND"
                               directory="/foo">
    <file:request-handler-advice-chain>
        <bean class="org.springframework.integration.handler.advice.ExpressionEvaluatingRequestHandlerAdvice">
            <property name="onSuccessExpression" value="payload.delete()"/>
        </bean>
    </file:request-handler-advice-chain>
</file:outbound-channel-adapter>

请咨询Reference Manual以获取更多信息。
