在spring boot batch中使用JobExecutionDecider

public class MyDecider implements JobExecutionDecider {
    
    @Override
    public FlowExecutionStatus decide(JobExecution jobExecution, StepExecution stepExecution) {
        // 根据特定条件进行判断
        if (someCondition) {
            return new FlowExecutionStatus("CONTINUE");
        } else {
            return new FlowExecutionStatus("SKIP");
        }
    }
}

@Configuration
@EnableBatchProcessing
public class BatchConfig {

    @Autowired
    private JobBuilderFactory jobBuilderFactory;

    @Autowired
    private StepBuilderFactory stepBuilderFactory;

    @Autowired
    private MyDecider myDecider;

    @Bean
    public Step myStep() {
        return stepBuilderFactory.get("myStep")
                .tasklet((contribution, chunkContext) -> {
                    // 步骤执行逻辑
                    return RepeatStatus.FINISHED;
                })
                .build();
    }

    @Bean
    public Job myJob() {
        return jobBuilderFactory.get("myJob")
                .start(myStep())
                .next(myDecider) // 使用决策器
                .from(myDecider).on("CONTINUE").to(anotherStep()) // 决策结果为"CONTINUE"时执行anotherStep
                .from(myDecider).on("SKIP").end() // 决策结果为"SKIP"时结束作业
                .end()
                .build();
    }
}
