在ItemReader Spring Batch中为JobParameter添加时间戳

@Bean
@StepScope
public ItemReader<MyObject> itemReader(@Value("#{jobParameters['timestamp']}") Date timestamp) {
    // 使用timestamp参数进行处理
    // ...
}

@Autowired
private JobLauncher jobLauncher;

@Autowired
private Job myJob;

public void runJob() {
    try {
        JobParameters jobParameters = new JobParametersBuilder()
                .addDate("timestamp", new Date())
                .toJobParameters();
        
        jobLauncher.run(myJob, jobParameters);
    } catch (Exception e) {
        // 异常处理
    }
}
