springboot项目启动成功后执行一段代码的两种方式

实现ApplicationRunner接口

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.ApplicationArguments;
import org.springframework.boot.ApplicationRunner;
import org.springframework.stereotype.Component;

@Component
public class DemoApplicationRunner implements ApplicationRunner {

Logger log = LoggerFactory.getLogger(DemoApplicationRunner.class);

@Override
public void run(ApplicationArguments applicationArguments) throws Exception {
log.info("项目启动完成！！！！！！！");
System.out.println("ApplicationRunner");
}
}

实现CommandLineRunner接口

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.CommandLineRunner;
import org.springframework.stereotype.Component;

@Component
public class DemoApplicationRunner implements CommandLineRunner {

Logger log = LoggerFactory.getLogger(DemoApplicationRunner.class);

@Override
public void run(String... strings) throws Exception {
    log.info("项目启动完成！！！！！！！");
   System.out.println("ApplicationRunner");
}

}
