Spring batch -Run JobLauncher -


i integrated spring batch in project , have problem in running joblauncher.

in class joblauncher have :

  public class xxxjoblauncher { @autowired @qualifier("testjob") job testjob;  @autowired joblauncher joblauncher;  @serviceactivator public void run(filemetadata filemetadata) {     ///      jobparametersbuilder jobparametersbuilder = new jobparametersbuilder();     jobparametersbuilder.addstring("uuiid", filemetadata.getuuid());     jobparametersbuilder.addlong("id", dataimport.getid());      try {         joblauncher.run(testjob, jobparametersbuilder.tojobparameters());     } catch (jobexecutionalreadyrunningexception | jobrestartexception | jobparametersinvalidexception | jobinstancealreadycompleteexception e) {         e.printstacktrace();     } }

for configuration use xml config :

configbatch.xml:

     <import resource="classpath:job-config.xml"/>  <bean id="jobrepositoryfactory" class="org.springframework.batch.core.explore.support.jobexplorerfactorybean">     <property name="datasource" ref="datasource"/>     <property name="tableprefix" value="batch_"/> </bean>  <bean id="jobrepository" class="org.springframework.batch.core.repository.support.simplejobrepository"       factory-bean="jobrepositoryfactory"/>  <bean id="batchtaskexecutor" class="org.springframework.scheduling.concurrent.threadpooltaskexecutor"       destroy-method="shutdown">     <property name="corepoolsize" value="6"/>     <property name="allowcorethreadtimeout" value="true"/>     <property name="waitfortaskstocompleteonshutdown" value="true"/> </bean>  <bean id="joblauncher" class="org.springframework.batch.core.launch.support.simplejoblauncher">     <property name="jobrepository" ref="jobrepository"/>     <property name="taskexecutor" ref="batchtaskexecutor"/> </bean>

in job-config.xml have :

   <batch:job id="testjob"            incrementer="incrementer"            job-repository="jobrepository">     <batch:step id="step1">         <batch:tasklet throttle-limit="4"                        transaction-manager="transactionmanager"                        task-executor="batchtaskexecutor">             <batch:chunk reader="xxxreader"                          processor="passthroughitemprocessor"                          writer="xxxwriter"                          skip-limit="100"                          commit-interval="10">                 <batch:skippable-exception-classes>                     <batch:include class="org.springframework.batch.item.file.flatfileparseexception"/>                 </batch:skippable-exception-classes>                 <batch:listeners>                     <batch:listener ref="xxxlistener"/>                 </batch:listeners>             </batch:chunk>         </batch:tasklet>     </batch:step> </batch:job>  <bean id="xxxreader"       class="com.reader.xxxreader"       scope="step">     <constructor-arg value="#{jobparameters[uuiid]}" name="uuiid"/> </bean>  <bean id="xxxwriter"       class="com.writer.xxxwriter"       scope="step">     <constructor-arg value="#{jobparameters[ id]}" name="id"/> </bean>  <bean id="xxxlistener"       class="com.listener.xxxlistener"> </bean>  <bean id="passthroughitemprocessor" class="org.springframework.batch.item.support.passthroughitemprocessor"/>  <bean id="incrementer" class="org.springframework.batch.core.launch.support.runidincrementer"/>

when debug in class joblauncher stop in jobluancher.run , have no exception it's seems spring batch doesn't recognizes reader , whriter !!is there suggestion?

i resolved problem in batchconfig.xml : 

<batch:job-repository id="jobrepository"                       data-source="datasource"                       transaction-manager="batchtransactionmanager"/>  <bean class="org.springframework.batch.core.configuration.support.jobregistrybeanpostprocessor">     <property name="jobregistry" ref="jobregistry"/> </bean>  <bean id="jobregistry" class="org.springframework.batch.core.configuration.support.mapjobregistry"/>  <bean id="joblauncher"       class="org.springframework.batch.core.launch.support.simplejoblauncher">     <property name="jobrepository" ref="jobrepository"/> </bean>  <bean id="batchtransactionmanager"       class="org.springframework.batch.support.transaction.resourcelesstransactionmanager"/>  <bean id="batchtaskexecutor"       class="org.springframework.scheduling.concurrent.threadpooltaskexecutor"       destroy-method="shutdown">     <property name="corepoolsize" value="4"/>     <property name="allowcorethreadtimeout" value="true"/>     <property name="waitfortaskstocompleteonshutdown" value="true"/> </bean>  <bean id="jobexplorer"       class="org.springframework.batch.core.explore.support.jobexplorerfactorybean">     <property name="datasource" ref="datasource"/> </bean>

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
