###22. SpringApplication
|
||
SpringApplication类提供了一种从main()方法启动Spring应用的便捷方式。在很多情况下，你只需委托给SpringApplication.run这个静态方法：
|
||
```java
|
||
public static void main(String[] args){
|
||
SpringApplication.run(MySpringConfiguration.class, args);
|
||
}
|
||
```
|
||
当应用启动时，你应该会看到类似下面的东西（这是何方神兽？？）：
|
||
```other

默认情况下会显示INFO级别的日志信息，包括一些相关的启动详情，比如启动应用的用户等。
