springboot自定义启动类

springboot中设置启动类，其实就是实现了一个接口ApplicationRunner,源码如下：

package org.springframework.boot;

@FunctionalInterface
public interface ApplicationRunner {
    void run(ApplicationArguments var1) throws Exception;
}

自己的实现类如下：

@Component
public class InitConfig implements ApplicationRunner {
	@Override
	public void run(ApplicationArguments applicationArguments) throws Exception {
		/**
		 * 这里可以添加一些其他逻辑，这里只是做一个演示，具体是实现了ApplicationRunner
		 */
		System.out.println("我启动了");

	}
}

启动项目：

2018-11-30 20:09:25.407  INFO 426428 --- [           main] o.s.b.w.servlet.FilterRegistrationBean   : Mapping filter: 'requestContextFilter' to: [/*]
2018-11-30 20:09:25.740  INFO 426428 --- [           main] o.s.s.concurrent.ThreadPoolTaskExecutor  : Initializing ExecutorService 'applicationTaskExecutor'

2018-11-30 20:09:25.988  INFO 426428 --- [           main] c.e.demo.SpringbootdemoApplication       : Started SpringbootdemoApplication in 4.335 seconds (JVM running for 5.323)
我启动了

这里只是做了简单的输出，可根据自己的需求进行相应的逻辑添加
