Struts 数据处理

方式一：直接获取servletAPI

核心类：ServletActionContext中的静态方法

HttpServletRequest request = ServletActionContext.getRequest();HttpServletResponse response = ServletActionContext.getResponse();

方式二：通过ActionContext类获取不同的Map

ActionContext ac = ActionContext.getContext();Map<String, Object> session = ac.getSession();Map<String, Object> application = ac.getApplication();Map<String, Object> request = ac.getContextMap();

方式三：通过实现接口的方法
