标签:1.通过ActionContext类(拿到的不是真正的servlet api,而是一个map)   ActionContext context = ActionContext.getContext();   context.getSession();   context.getApplication(); 2.通过ServletActionContext类(拿到的是真正的servlet api)   ServletActionContext.getRequest();   ServletActionContext.getResponse();   ServletActionContext.getPageContext(); 3.通过注入方式获取(拿到的是真正的servlet api)   * ServletContextAware、ServletRequestAware、ServletResponseAware接口   (1) 实现对应的接口:implements ServletRequestAware   (2) 声明私有属性例如 private HttpServletRequest request;   (3) 复写接口方法setsetServletRequest   public void setServletRequest(HttpServletRequest request) {     this.request = request;   }  struts2中在Action中如何获取servlet的api?标签:原文地址:http://www.cnblogs.com/zyh1994/p/5399495.html
