java Spring MVC HandlerInterceptorAdapter
我在SpringWeb模型视图控制器（MVC）框架中有这个类。SpringWeb模型视图控制器（MVC）框架的版本是3.2.8
这是我的servlet。xml
<bean id="sessionInterceptor" class="com.tdk.devices.support.context.SessionInterceptor" />

public class SessionInterceptor extends HandlerInterceptorAdapter {

}
private boolean sessionNeeded (HttpServletRequest request, Object handler) {

System.out.println ("***************************");
HttpSession session = request.getSession(false);
return (session == null || session.getAttribute(Const.SESSION_USER) == null) &&
!(handler instanceof LogoutController) &&
!(handler instanceof Error404Controller) &&
!(handler instanceof WelcomeController) &&
!(handler instanceof CBHomeController) &&
!(handler instanceof Error500Controller);
}
}
这是1号控制器
@Controller
public class CBHomeController extends CBController {
public static final Logger LOGGER = Logger.getLogger (CBHomeController.class);
/**
*
*/
@RequestMapping(value = { "/newdesign/manage/home",
"/newdesign/manage/home/"}, method = {RequestMethod.GET})
public String cbHome (HttpServletRequest request, Model model ) throws ExecutionException {
System.out.println ("*** CBHomeController ***");
return "cbHomeView";
}
}
当我把这个放在URL里的时候
http://127.0.0.1:7001/devices/newdesign/manage/home
JSP中的一切都正常，因为我看到了主页，但这是我在控制台中看到的：
*** CBHomeController ***

你确定不仅仅是浏览器请求fav吗。伊科
端口7001表示weblogic，system out表示不能只设置断点并检查请求URL。也许我的假设是错误的；如果我没有，那么设置一个可以设置断点的环境应该是你的首要任务，从长远来看，它将为你节省数小时——并为你节省你忘记删除的所有系统的文件空间：-）
另外，我对你的拦截器处理程序很感兴趣，我从来没有需要过这样的处理程序，通常会话会在需要时自动创建，比如Spring security。你能详细介绍一下这个拦截器吗？我觉得它很奇怪
