SHH整合Cookie取值问题~！大侠求助。。。。。。。。。

intiParam初始化方法，但是把取不到request.getCookies();public class CookieTools {
         private HttpServletRequest request;
private HttpServletResponse response;
public void initParam(HttpServletRequest request,HttpServletResponse response)
{
this.request =request;
this.response =response;
} public List getCookieVlaueFromCookieName(String cookieName)
{
initParam(request,response);
ArrayList returnCookieList =new ArrayList();
Cookie[] cookieArray =request.getCookies();
if(cookieArray != null)
{
for(int i=0;i<cookieArray.length;i++)
{
if(cookieArray[i].getName().equals(cookieName))
{
System.out.println(cookieArray[i].getValue());
returnCookieList.add(URLEncoder.encode(cookieArray[i].getValue()));
}
}
}
return returnCookieList;
}
}登录之后取得名字，Cooike里已经知道名字了  “loginUsername” 就这个~！public class text {
private CookieTools cookieTools = new CookieTools();
private List getUsernameList; public List getGetUsernameList() {
return getUsernameList;
} public void setGetUsernameList(List getUsernameList) {
this.getUsernameList = getUsernameList;
}
public String execute()
{
getUsernameList=cookieTools.getCookieVlaueFromCookieName("loginUsername");
System.out.println("username"
+ getGetUsernameList().get(0).toString());
return null;
}
