1.通过ActionContext的类访问

ActionContext context = ActionContext.getContext();
       context.put("requestName","requestNameMike");
       context.getSession().put("sessionName", "sessionName");
       context.getApplication().put("applictionName", "applictionName");

JSP中接收

request接收:${requestScope.requestName}<br>
session接收:${sessionScope.sessionName}<br/>
application接收：${applicationScope.applictionName}<br/>

2.通过特定xxxAware接口访问

实现接口 ServletRequestAware

public class TestParater extends ActionSupport implements ServletRequestAware

private HttpServletRequest request;

public void setServletRequest(HttpServletRequest request) {
       // TODO Auto-generated method stub
       this.request = request;
   }

request.setAttribute("ServletRequestAware", "ServletRequestAware");

jsp页面获取

String servletRequestAware = (String)request.getAttribute("ServletRequestAware");

3.通过servleActionContext

HttpServletRequest request = ServletActionContext.getRequest();
request.setAttribute("servletActionContext", "ServletActionContext");

jsp页面获取

String servletRequestAware = (String)request.getAttribute("servletActionContext");
