### 18. 使用@SpringBootApplication注解
很多Spring Boot开发者总是使用`@Configuration``@EnableAutoConfiguration`和`@ComponentScan`注解他们的main类。由于这些注解被如此频繁地一块使用特别是你遵循以上[最佳实践](14. Structuring your code.md)时Spring Boot提供一个方便的`@SpringBootApplication`选择。
该`@SpringBootApplication`注解等价于以默认属性使用`@Configuration``@EnableAutoConfiguration`和`@ComponentScan`。
```java
package com.example.myproject;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication // same as @Configuration @EnableAutoConfiguration @ComponentScan
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
```
