+  visit `localhost://localhost:8081`, frontend support hot reload.             
+   
+ * CORS problem
+    in this development mode, frontend will request `localhost:8080` to fetch data, this will cause a CORS problem, so we add a configuration in `I18nConfig.java` to support CORS, this configuration will only be active under **develop** mode, please select the right maven profile to support this.
