@Component
public class ApplicationRunnerImpl implements ApplicationRunner {
    @Override
    public void run(ApplicationArguments args) throws Exception {
        System.out.println("通过实现ApplicationRunner接口，在spring boot项目启动后打印参数");
        String[] sourceArgs = args.getSourceArgs();
        for (String arg : sourceArgs) {
            System.out.print(arg + " ");
        }
