struts2中訪問request和session

第一種方法：

 

Request:

通過com.opensymphony.xwork2

.ActionContext類以及org.apache.struts

2

.ServletActionContext類

HttpServletRequest

request

= ServletActionContext.getRequest

();

ActionContext context= ActionContext.getContext()

HttpServletRequest

request

=(HttpServletRequest

)ct.get(ServletActionContext.HTTP_REQUEST

);

 

Session：

Map session=ActionContext.getSession();

Map session=(Map)ActionContext.getContext().get(ActionContext.SESSION);

 

註：sturt2中session都被封裝成了Map類型，我們稱之為SessionMap如果我們想得到原始的HttpSession可以首先得到HttpServletRequest

對象,然後通過request

.getSession()來取得原始的HttpSession對象。一般情況下SessionMap已經可以完成所有的工作，我們不必再去碰底層的session了。

 

第二種方法：

 

 

public class TestAction implements ServletRequestAware, ServletResponseAware {<br /> protected HttpServletRequest request;<br /> protected HttpServletResponse response;<br /> protected HttpSession session;<br /> @Override<br /> public void setServletRequest(HttpServletRequest httpServletRequest) {<br /> this.request = httpServletRequest;<br /> this.session = httpServletRequest.getSession();<br /> }<br /> @Override<br /> public void setServletResponse(HttpServletResponse httpServletResponse) {<br /> this.response = httpServletResponse;<br /> }<br />}<br />
