Spring Batch provides reusable functions that are essential in processing large volumes of records, including logging/tracing, transaction management, job processing statistics, job restart, skip, and resource management. It also provides more advanced technical services and features that will enable extremely high-volume and high performance batch jobs through optimization and partitioning techniques. Simple as well as complex, high-volume batch jobs can leverage the framework in a highly scalable manner to process significant volumes of information.

特性

• Transaction management
• Chunk based processing
• Declarative I/O
• Start/Stop/Restart
• Retry/Skip
• Web based administration interface (Spring Cloud Data Flow)

快速开始

The quickest way to get started with Spring Batch is to use Spring Boot.

1. Once your build process is setup (using either Maven or Gradle) using Spring Boot, add the batch starter dependency

    <!-- Maven -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-batch</artifactId>
    </dependency>
   

    // Gradle
    compile("org.springframework.boot:spring-boot-starter-batch")
   

2. Create a configuration class to configure your job

    @Configuration
    public class BatchConfiguration {
   
      @Autowired
      private JobBuilderFactory jobBuilderFactory;
   
      @Autowired
      private StepBuilderFactory stepBuilderFactory;
   
      @Bean
      public Step step1() {
        return stepBuilderFactory.get("step1")
            .tasklet(new Tasklet() {
              public RepeatStatus execute(StepContribution contribution, ChunkContext chunkContext) {
                return null;
              }
            })
            .build();
      }
   
      @Bean
      public Job job(Step step1) throws Exception {
        return jobBuilderFactory.get("job1")
            .incrementer(new RunIdIncrementer())
            .start(step1)
            .build();
      }
    }
   

3. Create a main class to run your batch job from

    @EnableBatchProcessing
    @SpringBootApplication
    public class Main {
      public static void main(String [] args) {
        System.exit(SpringApplication.exit(SpringApplication.run(
            BatchConfiguration.class, args)));
      }
    }
   

4. You can now build your project and run it via java -jar <JAR_NAME> where <JAR_NAME> is the name of the jar your build system generates.
