struts2 Action中获取request, response对象的 几种 方法
struts2 Action中获取request, response对象的方法

第一种方法：

ActionContext ctx = ActionContext.getContext();                 HttpServletRequest request = (HttpServletRequest)ctx.get(ServletActionContext.HTTP_REQUEST);                 HttpServletResponse response = (HttpServletResponse)ctx.get(ServletActionContext.HTTP_RESPONSE);                   //ServletActionContext.APPLICATION;          //ServletActionContext.SESSION;          //ServletActionContext.PAGE_CONTEXT;        

第二种方法：
实现 ServletRequestAware

public class TestAction implements ServletRequestAware{      /**---*/      public void setServletRequest(HttpServletRequest request) {// 要复写这个方法request.setAttribute("key","value"); }}

第三种：更简单的一种。。

HttpServletRequest request = ServletActionContext.getRequest();
