Spring Batch 4.1.0.M2 发布，简化远程分区

Spring Batch 4.1.0.M2 已发布，可从 Maven Central、Github 和 Pivotal 下载仓库获取。

更新亮点包括：

简化远程分区

通过两个新的构建器来简化远程分区： RemotePartitioningMasterStepBuilder 和 RemotePartitioningWorkerStepBuilder ， 这些新构建器负责配置基础架构 bean 的繁重工作。

@Configuration@EnableBatchProcessing@EnableBatchIntegrationpublic class RemotePartitioningAppConfig {

   @Autowired
   private RemotePartitioningMasterStepBuilderFactory masterStepBuilderFactory;   @Autowired
   private RemotePartitioningWorkerStepBuilderFactory workerStepBuilderFactory;   @Bean
   public Step masterStep() {            return this.masterStepBuilderFactory
               .get("masterStep")
               .partitioner("workerStep", partitioner())
               .gridSize(10)
               .outputChannel(outgoingRequestsToWorkers())
               .inputChannel(incomingRepliesFromWorkers())
               .build();
   }   @Bean
   public Step workerStep() {            return this.workerStepBuilderFactory
               .get("workerStep")
               .inputChannel(incomingRequestsFromMaster())
               .outputChannel(outgoingRepliesToMaster())
               .chunk(100)
               .reader(itemReader())
               .writer(itemWriter())
               .build();
   }   // Middleware beans setup omitted}
