我在使用項目處理器中的作業參數時遇到問題。目前,代碼基本上設置爲:How to get Job parameteres in to item processor using spring Batch annotation,但我在運行時收到錯誤消息。另外,請注意我的示例代碼確實使用了一些彈簧集成進行處理。如何在ItemProcessor中使用註釋找不到jobParameters?

使用How to get Job parameteres in to item processor using spring Batch annotation的示例,我有以下代碼。人們會認爲這將是一個簡單的剪切和粘貼,然後在我的路上。我在其他地方使用jobParameters就好了,但它在ItemProcessor中肯定失敗。

ClaimBatchConfiguration:

... 
@Configuration 
@EnableBatchProcessing 
public class ClaimBatchConfiguration { 

... 

    @Bean 
    public ClaimLineItemProcessor claimLineItemProcessor() { 
      return new ClaimLineItemProcessor(); 
    } 

    @Bean 
    public Job importClaimJob() {  
     return claimJobBuilderFactory.get("importClaimJob").incrementer(new RunIdIncrementer()) 
       .listener(claimListener()).flow(importClaimStep1()).end().build(); 
    } 

    @Bean 
    public Step importClaimStep1() {  
     return claimStepBuilderFactory.get("importClaimStep1").<ClaimLine, ClaimLine> chunk(1) 
       .reader(claimFileReader(OVERRIDDEN_BY_EXPRESSION)).processor(claimLineItemProcessor()) 
       .writer(claimLineWriter()).faultTolerant().retryLimit(retryLimit) 
       .retry(DeadlockLoserDataAccessException.class).skipLimit(1) // default is 0 
       .skip(Exception.class).build(); 
    } 

ClaimFileMessagetoJobRequest.java:

... 
@Component 
public class ClaimFileMessageToJobRequest implements ApplicationContextAware { 
... 

    @Transformer(inputChannel = "claimInputChannel", outputChannel = "commonJobGateway") 
    public JobLaunchRequest messageToRequest(Message<File> message) { 
     logger.info("Load Claim Started at " + DateFormat.getCurrentDateTime()); 

     String[] fileNameParts = message.getPayload().getName().split("[_]"); 

     // handle error 
     JobParametersBuilder jobParametersBuilder = new JobParametersBuilder(); 

     jobParametersBuilder.addString("clientName", fileNameParts[1]); 

     logger.debug("Job Paramaters: " + jobParametersBuilder.toJobParameters()); 

     JobLaunchRequest request = new JobLaunchRequest(job, jobParametersBuilder.toJobParameters()); 

     return request; 
    } 

... 
} 

ClaimLineItemProcessor.java:

@Scope("step") 
public class ClaimLineItemProcessor implements ItemProcessor<ClaimLine, ClaimLine> { 

    @Value("#{jobParameters['clientName']}") 
    private String clientName; 

    // client name getter and setter here 

    @Override 
    public ClaimLine process(ClaimLine claimline) throws Exception { 
    logger.debug("Current Client Name" + clientName); 

    // bunch or work to really do 
     return claimline; 
    } 
}

@Scope("step")應該在bean定義(在ClaimBatchConfiguration),不在課堂上。此外,作爲FYI,您可以使用@StepScope作爲捷徑(同樣在bean定義上)。

有趣的是,我剛剛嘗試過,當你的答案進來,我仍然有錯誤。從測試:@StepScope的作品。 @Scope(「步驟」)失敗。 @Scope(value =「step」)失敗。 –

+0

爲了迴應我自己的評論,差異似乎是@StepScope設置的代理。我使用@Scope(value =「step」,proxyMode = ScopedProxyMode.TARGET_CLASS)進行了測試,並確定它的工作。 –
