我在项目处理器中使用作业参数时遇到问题.此时,代码基本上设置为：How to get Job parameteres in to item processor using spring Batch annotation但我在运行时收到错误.另请注意,我的示例代码确实使用了一些spring集成进行处理.

使用How to get Job parameteres in to item processor using spring Batch annotation的示例,我有以下代码.人们会认为这将是一个简单的剪切和粘贴然后在我的路上.我在其他地方使用jobParame就好了,但它肯定在ItemProcessor中失败了.
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;
}
}
解决方法: @Scope(“step”)应该在bean定义上(在ClaimBatchConfiguration中),而不是在类本身上.此外,作为一个FYI,您可以使用@StepScope作为快捷方式(也在bean定义上). 来源：https://www./content-4-260051.html
