Spring 批处理 -> 在读取器和处理器之间传递数据

Question

我想将我的唯一数据（storeId）从我的阅读器保存到我的处理器，但我无法得到它。

这是我的问题所涉及的读者部分：

@Component
public class MyOfferApi implements InitializingBean {

    @Value("${api.xApiMyOfferKey}")
    private String xApiKeyMyOffer;

    @Value("${api.myOffer.uri}")
    private String apiMyOfferUri;

    @Override
    public void afterPropertiesSet() {
        Assert.isTrue(apiMyOfferUri.endsWith("/"), "The myOffer URI must contain a '/' at the end");
    }

    private final OAuth2RestTemplate oAuth2RestTemplate;

    private static final Logger LOGGER = LoggerFactory.getLogger(MyOfferApi.class);

    public MyOfferApi(OAuth2RestTemplate oAuth2RestTemplate) { this.oAuth2RestTemplate = oAuth2RestTemplate; }

    List<MyOffer> callMyOfferAPI(String storeId) {
        LOGGER.info("Call api MyOffer for store {}", storeId);
        MyOffer[] myOfferTab = null;
        try {
            ResponseEntity<MyOffer[]> response = oAuth2RestTemplate.exchange(Objects.requireNonNull(makeUriMyOffer(storeId)), HttpMethod.GET, ApiUtils.getHttpEntity(xApiKeyMyOffer), MyOffer[].class);
            myOfferTab = response.getBody();
        } catch (HttpServerErrorException httpServerErrorException) {
            LOGGER.error(httpServerErrorException.getMessage(), httpServerErrorException);
        }
        System.out.print("show me my offerTab" + Arrays.toString(myOfferTab));
        return myOfferTab == null ? new ArrayList<>() : Arrays.asList(myOfferTab);
    }

    String makeUriMyOffer(String storeId) {
        return apiMyOfferUri + storeId + "/sports_teams";
    }
}

参数中的 StoreID 未在我的下一步（处理器）中定义，但我必须对这个 storeID 进行大量更改。 这是我的处理器：

public class EnrichFileProcessor implements ItemProcessor<MyOffer, ConsolidationLine> {

    @Override
    public ConsolidationLine process(@NotNull MyOffer myOffer) throws Exception {

        ConsolidationLine consolidationLine = new ConsolidationLine();

        // Common
        consolidationLine.setHorsect(myOffer.getStoreId());
        consolidationLine.setLibelle(myOffer.getLabel());
        consolidationLine.setInactive(COLUMN_INACTIF);
        consolidationLine.setSsinummag(myOffer.getStoreId());
        consolidationLine.setSsinummag("TEST");
        consolidationLine.setDocId(myOffer.getDocId());

        // EU
        consolidationLine.setLibcourt(myOffer.getLabel());

        // FR
        consolidationLine.setLevel(COLUMN_LEVEL);
        consolidationLine.setSsisectpar("TEST");
        return consolidationLine;
    }

如果需要，JobConfig 中有我有趣的方法

 @Bean
    public Job processJob() {
        return jobs.get("processJob")
                .incrementer(new RunIdIncrementer())
                .flow(enrichFileStep())
                .next(pushBucketFileStep())
                .end().build();
    }

    @Bean
    public ApiDataReader apiDataReader() {
        ApiDataReader apiDataReader = new ApiDataReader();
        apiDataReader.setMasterDataApi(masterDataApi);
        apiDataReader.setMyOfferApi(myOfferApi);
        return apiDataReader;
    }

    @Bean
    public Step enrichFileStep() {
        return steps.get("enrichFileStep").<MyOffer, ConsolidationLine>chunk(5)
                .reader(apiDataReader())
                .processor(enrichFileProcessor())
                .writer(enrichFileWriter(null))
                .build();
    }

    @Bean
    public EnrichFileProcessor enrichFileProcessor() {
        return new EnrichFileProcessor();
    }

有什么帮助吗？ 泰
