springMVC 学习笔记

spring mvc中核心Servlet的继承结构：

XXXAware在spring里表示对XXX感知，实现XXXAware，就可以通过实现对应的set-XXX,然后就可以使用XXX了。

例子：public interface ApplicationContextAware extends Aware 

void setApplicationContext(ApplicationContext applicationContext) throws BeansException;

实现ApplicationContextAware #setApplicationContext，spring就会自动调用setApplicationContext把ApplicationContext 传进来。

public interface EnvironmentCapable {

/**
* Return the Environment for this object
*/
Environment getEnvironment();

}
