Spring Batch Not reading from DB nor writing to file -

i want use multiple datasources, 1 spring batch metadata , other business data. batch job runs , not try connect secondarydatasource. can point out wrong configuration?

@configuration @enablebatchprocessing public class batchconfiguration extends defaultbatchconfigurer {      @override     @autowired     public void setdatasource(             @qualifier("batchdatasource") datasource batchdatasource) {         super.setdatasource(batchdatasource);     } }  public class springbatchconfig {      @autowired     private jobbuilderfactory jobs;      @autowired     private stepbuilderfactory steps;      private static final string query_find_students = "select * ...";      @bean     itemreader<dotdetailsdto> reader(             @qualifier("secondarydatasource") datasource datasource)             throws sqlexception {         jdbccursoritemreader<dotdetailsdto> databasereader = new jdbccursoritemreader<>();          databasereader.setdatasource(datasource);         databasereader.setsql(query_find_students);         databasereader.setrowmapper(new dotrowmapper());          return databasereader;     }      @bean     public itemprocessor<dotdetailsdto, dotdetailsdto> itemprocessor() {         return new customitemprocessor();     }      @bean     public itemwriter<dotdetailsdto> writer() throws exception {         flatfileitemwriter<dotdetailsdto> writer = new flatfileitemwriter<dotdetailsdto>();         writer.setresource(new classpathresource("file:test.csv"));         delimitedlineaggregator<dotdetailsdto> dellineagg = new delimitedlineaggregator<dotdetailsdto>();         dellineagg.setdelimiter(",");         beanwrapperfieldextractor<dotdetailsdto> fieldextractor = new beanwrapperfieldextractor<dotdetailsdto>();         fieldextractor.setnames(new string[] { "airwaybillnumber",                 "outbounddate", "orig", "dest", "lotnumber",                 "lotflightnumber", "lotorig", "lotdest", "lotpcs", "lotwt",                 "lotflightdepartdate", "iatacode" });         dellineagg.setfieldextractor(fieldextractor);         writer.setlineaggregator(dellineagg);         writer.afterpropertiesset();         return writer;     }      @bean     protected step step1(itemreader<dotdetailsdto> reader,             itemprocessor<dotdetailsdto, dotdetailsdto> processor,             itemwriter<dotdetailsdto> writer) throws sqlexception {         return steps.get("step1").<dotdetailsdto, dotdetailsdto> chunk(10)                 .reader(reader).processor(processor).writer(writer).build();     }      @bean(name = "firstbatchjob")     public job job(@qualifier("step1") step step1) {         return jobs.get("firstbatchjob").start(step1).build();     }  }  public class datasourceconfiguration {      @bean(name="batchdatasource")     public datasource datasource() throws sqlexception {         basicdatasource datasource = new basicdatasource();         ...         return datasource;     }      @bean     public jdbctemplate jdbctemplate(             @qualifier("batchdatasource") final datasource datasource) {         return new jdbctemplate(datasource);     }      @primary     @bean(name="secondarydatasource")     public datasource secondarydatasource() throws sqlexception {         oracledatasource secondarydatasource = new oracledatasource();         ...         return secondarydatasource;     }      @bean     public jdbctemplate secondaryjdbctemplate(             @qualifier("secondarydatasource") final datasource secondarydatasource) {         return new jdbctemplate(secondarydatasource);     } }  public static void main(string[] args) {     // spring java config     annotationconfigapplicationcontext context = new annotationconfigapplicationcontext();     context.register(datasourceconfiguration.class);     context.register(batchconfiguration.class);     context.register(springbatchconfig.class);     context.refresh();      joblauncher joblauncher = (joblauncher) context.getbean("joblauncher");     job job = (job) context.getbean("firstbatchjob");     system.out.println("starting batch job");     try {         jobexecution execution = joblauncher.run(job, new jobparameters());         system.out.println("job status : " + execution.getstatus());         system.out.println("job completed");     } catch (exception e) {         e.printstacktrace();         system.out.println("job failed");     }  } 

wow after 2 days figured out issue was. not providing new jobparameters because of running same old broken job on , over.

below fix in main method.

public static void main(string[] args) {      annotationconfigapplicationcontext context = new annotationconfigapplicationcontext();     context.register(datasourceconfiguration.class);     context.register(batchconfiguration.class);     context.register(springbatchconfig.class);     context.refresh();      joblauncher joblauncher = (joblauncher) context.getbean("joblauncher");     job job = (job) context.getbean("firstbatchjob");     system.out.println("starting batch job");     try {         dateformat dateformat = new simpledateformat("yyyy/mm/dd hh:mm:ss");         date date = new date();         jobparameters jobparam =             new jobparametersbuilder().addstring("jobdate",dateformat.format(date)).tojobparameters();         jobexecution execution = joblauncher.run(job, jobparam);         system.out.println("job status : " + execution.getstatus());         system.out.println("job completed : " + execution.getjobid());     } catch (exception e) {         e.printstacktrace();         system.out.println("job failed");     }  }
