/**
 	* spring的工具类，这个类很重要，要在普通类里调用spring注入的bean对象必须通过这个类
 	* 通过注解是没用的，因为普通类不符合spring 或者 mvc机制
 	*/

public class SpringUtil implements ApplicationContextAware {	
private static ApplicationContext applicationContext;  

@Override  
public void setApplicationContext(ApplicationContext context)  
    throws BeansException {  
    SpringUtil.applicationContext = context;

}

以上就是springmvc的实例。
