配置代码，启动的时候走到了
@加贝
public void onHandlerConfig(JfinalHandlers handlers) {
handlers.add(new UrlHandler("*", false));
//对应 JFinalConfig 的 configHandler
}

处理代码，一直没有被调用
public void handle(String target, HttpServletRequest request, HttpServletResponse response, boolean[] isHandled) {
System.out.println("GET MATCHED REQUEST: \n"+ request.getRequestURI() + "\n WITHDATA: \n" + request.getParameterMap());
if (urlPattern.matcher(target).matches()) {
process(target, request, response, isHandled);
next.handle(target, request, response, isHandled);
} else {
next.handle(target, request, response, isHandled);
}
}
