Spring mvc 中快速获取request、reponse、session

一：创建一个基本控制器类：

public class BaseController extends HandlerInterceptorAdapter{

public static HttpServletRequest request;

public static HttpServletResponse reponse;

public static HttpSession session;

@Override

public boolean preHandle(HttpServletRequest request,

HttpServletResponse response, Object handler) throws Exception {

BaseController.request = request;

BaseController.reponse = response;

BaseController.session = request.getSession();

return super.preHandle(request, response, handler);

}

@InitBinder

protected void initBinder(WebDataBinder binder) {

binder.registerCustomEditor(Date.class, new CustomDateEditor(

new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"), true));

}

}

二：注册这个实现拦截器的主控制器：(在子mvc配置文件.xml 中实现)
1  拦截所有请求

<!-- 注册拦截器   -->

<mvc:interceptors>

<bean class="com.base.BaseController"></bean>

</mvc:interceptors>

2  拦截指定请求

<!-- 注册拦截器 -->

<mvc:interceptors>

<mvc:interceptor>

<mvc:mapping path="/*" />

<bean class="com.base.BaseController"></bean>

</mvc:interceptor>

</mvc:interceptors>

三 所有的控制器可以实现这个基类，从而访问request、respons、session
个人理解：由于实现拦截器功能的bean 并发单态、或者控制器并非单态，所以每次请求的static request  并不是同一个对象
