获取命令行参数作为 @Scheduled spring boot 的 spring 批处理作业参数 [英] Get command line parameter as spring batch job parameters for @Scheduled spring boot

问题描述

下面是我的 spring boot 主类，我有 @Scheduled beans

Below is my spring boot main class , where I have @Scheduled beans

@EnableScheduling
@EnableBatchProcessing
@SpringBootApplication(scanBasePackages = { "com.mypackage" })
public class MyMain {

    @Autowired
    private JobLauncher jobLauncher;

    @Autowired
    private Job job;


    public static void main(String[] args) throws Exception {

        SpringApplication.run(MyMain.class, args);
    }


    @Scheduled(cron = "0 00 05 * * ?")
    private void perform() throws Exception {
        jobLauncher.run(job, new JobParameters());
    }
}

我将从命令行接收参数，我需要将其作为作业参数.我怎样才能实现与 @Scheduled 注释的方法一样不接受任何参数.

I will be receiving parameters from command line which I need to put as job parameters . How can I achieve the same as @Scheduled annotated methods does not take in any parameter.

推荐答案

您可以注入 ApplicationArguments 类型的 bean 并使用它来获取应用程序参数:

You can inject a bean of type ApplicationArguments and use it to get application arguments:

@EnableScheduling
@EnableBatchProcessing
@SpringBootApplication
public class MyMain {

    @Autowired
    private JobLauncher jobLauncher;

    @Autowired
    private Job job;

    @Autowired
    private ApplicationArguments applicationArguments;


    public static void main(String[] args) throws Exception {
        SpringApplication.run(MyMain.class, args);
    }

    @Scheduled(cron = "0 00 05 * * ?")
    private void perform() throws Exception {
        String[] sourceArgs = applicationArguments.getSourceArgs();
        JobParameters jobParameters; // create job parameters from sourceArgs
        jobLauncher.run(job, jobParameters);
    }
}

您可以在 访问应用程序参数 部分.

You can find more details about the ApplicationArguments type in the Accessing Application Arguments section.
