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();
