JobParameter＆ItemReader

Question

私はitemReaderのJobParametersにアクセスしようとしていますが、私は春のユーザーガイドの "JobとStep AttributesのLate Binding"に従っていますが、動作させることはできません。 春バッチ2.1.8 春コア3.0.5

<bean id="ipcFileReader" scope="step" class="org.springframework.batch.item.file.FlatFileItemReader"> 
    <property name="resource" value="#{jobParameters['filename']}"/> 
    <property name="lineMapper" ref="lineMapper"/> 
    <property name="comments" value="#"/> 
</bean> 

私のテストクラス：ここ

は私の構成です

@TestExecutionListeners({DependencyInjectionTestExecutionListener.class,StepScopeTestExecutionListener.class}) 
@ContextConfiguration 
public class IpcFileReaderTest { 

@Autowired 
private ItemReader<Client> ipcFileReader; 

public StepExecution getStepExecution(){ 
    StepExecution execution = MetaDataInstanceFactory.createStepExecution(); 
    execution.getExecutionContext().putString("filename",System.getProperty("user.dir") + "/src/test/resources/OMC_File/OMC_Test_1.csv"); 
    return execution; 

@Test 
public void testReader() throws UnexpectedInputException, ParseException, NonTransientResourceException, Exception{ 
    Assert.assertNotNull(ipcFileReader.read()); 
} 
} 

しかし、私は常に、このエラーを得た：

Error creating bean with name 'lazyBindingProxy.lazyBindingProxy.ipcFileReader#execution#1234' defined in class path resource [applicationContext-Ipc.xml]: Initialization of bean failed; nested exception is java.lang.IllegalStateException: Cannot bind to placeholder: jobParameters['filename'] 

Thxを

Answer 1

は実は、これは非常にマイナーなタイプミスが原因です。

#{jobParameters['filename']} 

は次のようになります。

#{jobParameters[filename]} 

単一引用符は必要ありません。私はJobParametersを渡すために、このunittestのを使用してい
