问题 I am starting to learn Spring Boot. I am struggling to find an example with multiple RestControllers, which indicates to me that I may be doing something wrong. I am trying a very simple example: The goal is to make calls like the following: localhost:8080/ localhost:8080/employees/bob localhost:8080/departments I can only get localhost:8080/ to display.

问题 I'm at the point now where i really want to organize my code in a way that makes it more scalable and manageable. i want to get a better understanding of the MVC architectural in javascript without using a framework. So this is what i understand thus far (please please please correct me if i'm wrong): Model : an organized structure of the sites/web apps content(pics, copy, downloadable content, etc...) that also has logic needed in the manipulation of the content. so in javascript the model

The view means presentation of the model in a particular format. The controller responds to the user input and performs interactions on the data model objects. The controller receives the input, optionally validates it and then passes the input to the model. I understand that the View should not be able to

问题 I am writing program with GUI using MVC design pattern. I have a question concerning using ActionListeners. According to the MVC pattern, all of the ActionListeners should be included into Controller. Normally, as I believe they will be implemented into inner classes like. However in case of many buttons etc. is it a good idea to move those inner classes to separate files in the same package? I know that they will not be inner classes any more, so is it a good design?

The search bar does not seem to be connected to my list of objects. :( Let me show you what I've done. App.RecordCategoriesController = Ember.ArrayController.extend({ searchResult: function(){ var searchTerm = this.get('searchTerm'); var regExp = new RegExp(searchTerm,'i'); this.get('model').set('content',this.store.filter('recordCategory',function(item){ return

问题 I have few comboboxes with very dig data sets within ~ 100K rows and more. I tried it with QStandardItemModel - works fast enough if model is preloaded, also model loading takes few seconds if performed in separate thread. Tried comboboxes with QSqlQueryModel without threading to improve performance but experienced it works much slower than QStandardItemModel (in our project QSqlQueryModel works very fast with such amount of data with QTreeView for example). What could be the problem here? Is
