对于第二页以后，JdbcPagingItemReader不会自动为sortkey占位符设置值

Question

我正在使用JdbcPagingItemReader，如下所示

Setup.hs

截至目前，我按照以下方式开展工作（因为我对Spring批次很新）

@Bean
    public ItemReader<RemittanceVO> reader() {

        JdbcPagingItemReader<RemittanceVO> reader = new   JdbcPagingItemReader<RemittanceVO>();
        reader.setDataSource(dataSource);
        reader.setRowMapper(new RemittanceRowMapper());
        reader.setQueryProvider(queryProvider);
        reader.setPageSize(100);
        return reader;
    }


@Bean
    public PagingQueryProvider queryProvider() throws Exception{
        SqlPagingQueryProviderFactoryBean queryProviderBean= new SqlPagingQueryProviderFactoryBean();
        queryProviderBean.setDataSource(dataSource);
        queryProviderBean.setSelectClause(Constants.REMITTANCES_SELECT_CLAUSE);
        queryProviderBean.setFromClause(Constants.REMITTANCES_FROM_CLAUSE);
        queryProviderBean.setWhereClause(Constants.REMITTANCES_WHERE_CLAUSE);
        queryProviderBean.setSortKey(Constants.REMITTANCES_SORT_KEY);
        PagingQueryProvider queryProvider = queryProviderBean.getObject();
        return queryProvider;
    }

我正在以SpringBoot应用程序运行此应用程序。它成功获取前100个记录并移交给处理器，然后下一个查询失败。查询失败，因为尚未在其中放置排序键值。这是查询中的JobLauncher jobLauncher = (JobLauncher) ctx.getBean("jobLauncher"); Job job = (Job) ctx.getBean("runRCMatcher"); try { JobExecution execution = jobLauncher.run(job, new JobParameters()); }catch (Exception e) { e.printStackTrace(); }

我哪里错了？

我的数据库是DB2所以我想应该使用 - AND ((REMIT_ID > ?)) ORDER BY REMIT_ID ASC FETCH FIRST 100 ROWS ONLY;

步骤＆amp;作业定义为，

Db2PagingQueryProvider

指定的排序键是表列名称 - @Bean public Step step1(StepBuilderFactory stepBuilderFactory, ItemReader<RemittanceVO> reader, ItemWriter<RemittanceClaimVO> writer, ItemProcessor<RemittanceVO, RemittanceClaimVO> processor) { return stepBuilderFactory.get("step1") .<RemittanceVO, RemittanceClaimVO> chunk(100).reader(reader) .processor(processor).writer(writer).build(); } @Bean public Job runRCMatcher(JobBuilderFactory jobs, Step s1) { return jobs.get("RCMatcher") .incrementer(new RunIdIncrementer()) .flow(s1) .end() .build(); } ，它是表的主键，类型为Constants.REMITTANCES_SORT_KEY
