1.注入bean
@Bean
@Qualifier(DispatcherServletAutoConfiguration.DEFAULT_DISPATCHER_SERVLET_BEAN_NAME)
public DispatcherServlet dispatcherServlet() {return new com.admin.core.conf.MyDispatcherServlet();
}2.重写doDispatch方法，
/*** 重写doDispatch方法，该方法是所有请求得总入口，把request转到自定义的类里面**/
public class MyDispatcherServlet extends DispatcherServlet
{private static final long serialVersionUID = 1L;@Overrideprotected void doDispatch(HttpServletRequest request, HttpServletResponse response)throws Exception{super.doDispatch(new MyRequest(request), response);}}
1.这里可以根据需求对request进行操作，request默认是不能操作的
