錯誤處理零記錄與拆分批處理：mule esb

Question

我得到了錯誤，而0記錄與拆分..With一個記錄或多個記錄它工作正常 但如果沒有記錄與拆分然後它給出錯誤 我得到這個錯誤

org.mule.api.MessagingException: Object "java.lang.String" not of correct type. It must be of type "{interface java.lang.Iterable,interface java.util.Iterator,interface org.mule.routing.MessageSequence,interface java.util.Collection}" (java.lang.IllegalArgumentException) (com.mulesoft.module.batch.exception.BatchException). Message payload is of type: String at org.mule.execution.ExceptionToMessagingExceptionExecutionInterceptor.execute(ExceptionToMessagingExceptionExecutionInterceptor.java:32) at org.mule.execution.MessageProcessorNotificationExecutionInterceptor.execute(MessageProcessorNotificationExecutionInterceptor.java:107) at org.mule.execution.MessageProcessorExecutionTemplate.execute(MessageProcessorExecutionTemplate.java:44) at org.mule.processor.BlockingProcessorExecutor.executeNext(BlockingProcessorExecutor.java:88) at org.mule.processor.BlockingProcessorExecutor.execute(BlockingProcessorExecutor.java:59) at org.mule.processor.chain.DefaultMessageProcessorChain.doProcess(DefaultMessageProcessorChain.java:80) 

我的流程是遵循

<batch:job name="testBatch"> 
     <batch:input> 
      <component class="org.test.d1.Find" doc:name="Java"/> 
      <file:outbound-endpoint path="test" outputPattern="test.xml" responseTimeout="10000" doc:name="File"/> 

      <logger message="COUNT -&gt; #[xpath('fn:count(//po:Account)')]" level="INFO" doc:name="Logger"/> 
      <expression-filter expression="#[xpath('fn:count(//po:Account)')!=0.0]" doc:name="Expression"/> 
      <splitter evaluator="xpath" expression="//po:Account" doc:name="Splitter"/> 
      <collection-aggregator failOnTimeout="true" doc:name="Collection Aggregator"/> 
     </batch:input> 
     <batch:process-records> 
      <batch:step name="Batch_Step"> 
      </batch:step> 
     </batch:process-records> 
     <batch:on-complete> 
      <logger level="INFO" doc:name="Logger"/> 
      <set-payload value="Total Record : #[payload.totalRecords] fail Records : #[payload.failedRecords] successfull records :#[payload.successfulRecords +'\n'] " doc:name="Set Payload"/> 

     </batch:on-complete> 
    </batch:job> 

請幫我解決這個錯誤。謝謝

它自我說你得到一個字符串作爲輸入到分解器組件導致的問題的異常。

確保你給一個分離器組件一個迭代對象。
