若是你想在Spring Boot启动的时候运行一些特定的代码,你能够实现接口ApplicationRunner
或者CommandLineRunner
,这两个接口实现方式同样,它们都只提供了一个run方法。spring
CommandLineRunner:启动获取命令行参数。微信
public interface CommandLineRunner { /** * Callback used to run the bean. * @param args incoming main method arguments * @throws Exception on error */ void run(String... args) throws Exception; }
ApplicationRunner:启动获取应用启动的时候参数。app
public interface ApplicationRunner { /** * Callback used to run the bean. * @param args incoming application arguments * @throws Exception on error */ void run(ApplicationArguments args) throws Exception; }
import org.springframework.boot.* import org.springframework.stereotype.* @Component public class MyBean implements CommandLineRunner { public void run(String... args) { // Do something... } }
或者这样命令行
@Bean public CommandLineRunner init() { return (String... strings) -> { }; }
