springboot项目启动成功后执行一段代码的两种方式

package com.lnjecit.lifecycle;

import org.springframework.boot.ApplicationArguments;
import org.springframework.boot.ApplicationRunner;
import org.springframework.core.annotation.Order;
import org.springframework.stereotype.Component;

@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 + " ");
        }
        System.out.println();
    }
}
