Chunk based processing(基于块的处理) Declarative I/O(声明式的输入输出) Start/Stop/Restart(启动/停止/再启动) Retry/Skip(重试/跳过) 框架一共有4个主要角色: JobLauncher是任务启动器,通过它来启动任务,可以看做是程序的入口。 Job代表一个具体的任务。
首先使用@Configuration和@EnableBatchProcessing注解将类标记为Spring Batch的配置类。然后,使用JobBuilderFactory和StepBuilderFactory创建作业和步骤的构建器。在step1方法中,定义了一个简单的任务块,打印"Hello, Spring Batch!"并返回RepeatStatus.FINISHED。最后,在job方法中,使用jobBuilderFactory创建一个作业,并将step1...

55.1.2 Parallel Processing Batch jobs often process large amounts of data or perform computationally expensive operations. Batch applications can benefit from parallel processing in two scenarios. Steps that do not depend on each other can run on different threads. Chunk-oriented steps where the proc...
