### 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](http://docs.spring.io/spring-boot/docs/current-SNAPSHOT/reference/htmlsingle/#using-boot-structuring-your-code)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);
|
||
}
|
||
|
||
}
|
||
```
