Spring Boot 注解启动的两种方式

<strong>package com.example.myproject;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

@Configuration
@EnableAutoConfiguration
@ComponentScan
public class Application {

public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}

}</strong>

<strong>package com.my.data.cache;

import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* 项目启动器
* @author wangbowen

*/
@SpringBootApplication//必须标注该注解才能扫描程序里面的注解组件
public class SimpleApplication  implements CommandLineRunner{

@Override
public void run(String... args) throws Exception {
System.out.println("hello!Spring Boot");
}

public static void main(String[] args) {
SpringApplication.run(SimpleApplication.class, args);
}
}
