struts2改造项目 - ＆gt;编译错误

Question

我有下面的代码，但它有编译错误。它从struts1迁移到struts2。我试图在网上搜索但没有用，例如＆＃34; resetToken struts2＆＃34;或＆＃34; getLocalAddr请求＆＃34; ... 请帮忙!!!

HttpServletRequest request = ServletActionContext.getRequest();

String serverNumber = request.getLocalAddr().substring(request.getLocalAddr().length()-1);
// *it said The method getLocalAddr() is undefined for the type HttpServletRequest* ...

resetToken(request);
//*The method resetToken(HttpServletRequest) is undefined for the type CardAction*
