# 线程池核心线程数
spring.task.execution.pool.core-size=10
# 线程池最大线程数
spring.task.execution.pool.max-size=20
# 线程池队列容量
spring.task.execution.pool.queue-capacity=100

@Configuration
@EnableBatchProcessing
public class BatchConfig {

    @Autowired
    private JobBuilderFactory jobBuilderFactory;

    @Autowired
    private StepBuilderFactory stepBuilderFactory;

    @Autowired
    private JobLauncher jobLauncher;

    @Autowired
    private TaskExecutor taskExecutor;

    @Bean
    public Job myJob() {
        return jobBuilderFactory.get("myJob")
                .start(myStep())
                .build();
    }

    @Bean
    public Step myStep() {
        return stepBuilderFactory.get("myStep")
                .<Input, Output>chunk(10)
                .reader(reader())
                .processor(processor())
                .writer(writer())
                .taskExecutor(taskExecutor)
                .build();
    }

    // 其他配置方法...

}

@Autowired
private JobLauncher jobLauncher;

@Autowired
private Job myJob;

public void runJob() throws Exception {
    JobParameters jobParameters = new JobParametersBuilder()
            .addString("jobParam", "value")
            .toJobParameters();
    jobLauncher.run(myJob, jobParameters);
}
