Struts2中获取和设置request对象属性

１.通过ActionContext方式

import javax.servlet.http.HttpServletRequest;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;

ActionContext cxt = ActionContext.getContext();

HttpServletRequest request = (HttpServletRequest)cxt.get(ServletActionContext.HTTP_REQUEST);

String vAttr = request.getAttribute("attrName");

cxt.put("attrName2","attrName2Value"); request.setAttribute("attrName2","attrName2Value");

2.通过ServletActionContext方式

import org.apache.struts2.ServletActionContext;
import javax.servlet.http.HttpServletRequest;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;

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

String userName = (String)request.getAttribute("attrName1");

request.setAttribute("attrName2","attrName2Value");
