1、引入如下依赖:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>
2、SpringBoot的主配置类实现 CommandLineRunner 接口
@SpringBootApplication
public class DemoApplication implements CommandLineRunner {
public static void main(String[] args) {
new SpringApplicationBuilder()
.sources(DemoApplication.class) // SpringBoot主配置类
.bannerMode(Banner.Mode.CONSOLE) // 在启动之前作相关配置
.run(args);// 启动
}
@Override
public void run(String... args) throws Exception {
System.out.println("Hello");
}
}
3、覆写 CommandLineRunner 接口的 run() 方法,在 run 方法中编写具体的处理逻辑
