JSR 352的Java批次：當一個分裂的內部

裏面下面的例子只是一個分區計劃行不通 - >塊 - >分區

問題是，如果我把流程放在一個分區中，分區計劃中設置的參數將無法正常工作。如果刪除拆分並將流程放入作業中，它將正常工作。下面的例子西港島線只是打印：空空

，但如果我刪除拆分，將打印 valueTest1 valueTest2

謝謝！馬蒂亞斯

READER

package testbatch; 

import javax.batch.api.BatchProperty; 
import javax.batch.api.chunk.AbstractItemReader; 
import javax.inject.Named; 

@Named 
public class MyItemReader extends AbstractItemReader { 

    @BatchProperty 
    String prop1; 

    @Override 
    public Object readItem() throws Exception { 
     System.out.println(prop1); 
     return null; 
    } 
}

主要

package testbatch; 

import javax.batch.operations.JobOperator; 
import javax.batch.runtime.BatchRuntime; 

public class TestBatch { 

    public static void main(String[] args) { 
     JobOperator jobOperator = BatchRuntime.getJobOperator(); 
     jobOperator.start("myJob", null); 
    } 
}
