问题 I'm trying to read a CSV file with dates with Spring Batch, but I am having trouble parsing a date into a LocalDateTime Object: Field error in object 'target' on field 'date': rejected value [2017-07-20 04:15:25.0]; codes [typeMismatch.target.date,typeMismatch.date,typeMismatch.java.time.LocalDateTime,typeMismatch]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [target.date,date]; arguments []; default message [date]]; default message [Failed to convert

问题 I cannot understand the difference between multi-threading and partitioning in Spring batch. The implementation is of course different: In partitioning you need to prepare the partitions then process it. I want to know what is the difference and which one is more efficient way to process when the bottleneck is the item-processor. 回答1: TL;DR; Neither approach is intended to help when the bottleneck is in the processor. You will see some gains by having multiple items going through a processor

问题 I am working on Spring Boot and Batch Project and using spring Batch decider. Error The method next(Step) is undefined for the type FlowJobBuilder return jobBuilderFactory.get("sampleJob") .incrementer(new RunIdIncrementer()) .start(abcStep(stepBuilderFactory, abcReader)) .next(sampleDecider()) .from(sampleDecider()) .on(MDSConst.SUCCESS).to(xyxStep(stepBuilderFactory, xyzReader)) .from(sampleDecider()) .on(MDSConst.FAILED).end().build() .next(mnoStep(stepBuilderFactory, mnoReder)) .build();
