使用demo

结果

@Component
    public class TestImplApplicationRunner implements ApplicationRunner {
        @Override
        public void run(ApplicationArguments args) throws Exception {
            System.out.println(args);
            System.out.println("这个是测试ApplicationRunner接口");
        }
    }

例2：

@Component
    public class Test implements CommandLineRunner {
        @Override
        public void run(String... args) throws Exception {
            System.out.println("测试CommandLineRunner");
        }
    }
