Spring batch generating reports -

i generate summary report @ end of batch execution.

for ex: have itemprocessor receives accountid.

for every accountid: marketplaceid's every marketplaceid: call real time availability

at end of batch execution need provide nice summary in file shows,

• number of accounts processed
• number of marketplaceids each accoutid
• number of marketplaceids failed real time availability
• time took processing 1 accountid

question

1. where persist intermediate results ie. different count on each iteration
2. how counts next step summary file writer

would great if provide directions.

thanks.

write tasklet prepare nice summery , put tasklet last step in job

     <step id="summeryfile" >         <tasklet ref="summaryfilepreparationtasklet"/>     </step> 

and bean configuration is

<bean id="summaryfilepreparationtasklet" class="com.baji.batch.summarypreparationfile"> 

and class file is

 package com.baji.batch;      import org.springframework.batch.core.stepcontribution;     import org.springframework.batch.core.scope.context.chunkcontext;     import org.springframework.batch.core.step.tasklet.tasklet;     import org.springframework.batch.repeat.repeatstatus;      /**      * @author      * bhaji shaik      * may 30, 2015      */     public class summarypreparationfile implements tasklet {          @autowired private holder holder;         @override         public repeatstatus execute(stepcontribution arg0, chunkcontext chunkcontext) throws exception {                     holder.getresults1();                    //write own code prepare neat summary preparation file             return null;         }      }

 import org.springframework.stereotype.component;      @component     public class holder {         private list<integer> results1;         private list<integer> results2;           //setter , getter methods     }
