springboot在启动完成之后执行提示的方法

有两种方式

1.实现 ApplicationRunnerImpl

eg:

package com.example.demo.configure;

import org.springframework.boot.ApplicationArguments;
import org.springframework.boot.ApplicationRunner;
import org.springframework.stereotype.Component;

@Component
public class ApplicationRunnerImpl implements ApplicationRunner {
    @Override
    public void run(ApplicationArguments args) throws Exception {
        System.out.println("application start...");
    }
}

2.实现 CommandLineRunnerImpl

eg:

package com.example.demo.configure;

import org.springframework.boot.CommandLineRunner;
import org.springframework.stereotype.Component;

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

若是有多个实现类,则需要加上@Order注解,按照其中的value值从小到大执行。
