问题 In Struts2, a controller dispatches a Request to an Action and the Action passes it to back-end logic, which could be regarded as a very big "model", to process the request and JSP represents Views. How to define the Action in Struts2 ? Definitely it's not View... is it the Controller or Model? 回答1: Struts actions are controllers in the sense of the MVC pattern. I think the discussion of the value stack and ActionContext , as well as getter methods in action classes confuses the issue. In

问题 How to use lazy loading in Spring MVC? I'm using eager at this moment, but this makes my app works slowler. This is part of my domain: @ManyToMany(fetch = FetchType.EAGER) @JoinTable(name = "NEWS_TAG", joinColumns = @JoinColumn(name = "NEWS_ID"), inverseJoinColumns = @JoinColumn(name = "TAG_ID")) private List<Tags> tags = new ArrayList<Tags>(); public List<Tags> getTags() { return this.tags; } And dao: public List<News> getSomeNews(long b, long hm) { List<News> news = (List<News>)

问题 I'm new to the OOP paradigm (and AJAX/jQuery), but would like to create a basic site employing MVC architecture, in PHP, with AJAX functionality. I drew up a brief diagram of how I currently 'understand' the architecture. Presumably when AJAX is used, that acts as the controller to interact with the model directly to retrieve whatever functionality is needed? The filenames I added are just to give you an idea of what I 'think' should be included. e.g. index.php would be a html/css template

问题 Is there a difference in the working between the Membership Provider of Webforms and Membership Provider of MVC 3? 回答1: No. The membership provider is part of the System.Web.Security namespace Webforms is the System.Web.UI namespace MVC is the System.Web.Mvc namespace Therefore, there are no dependencies. In other words, you'll be making the same membership calls with the same membership objects in an MVC application as you would in a WebForms application. 回答2: No, MVC is just a design

问题 I am new to MVC and I notice that the view pages can look pretty nasty with all the intermixed script tags. Does it make sense to generate the HTML in a method in the view code-behind and then just insert the string result of the method as a single bit of script? For example: <div><%= GenerateTonsOfHTMLFromSomeIEnumerable() %></div> Is this contrary to the MVC philosophy? Dumb for some other reason, like performance? Does it have any merit? 回答1: It's a matter of practice. Here's an

问题 I've never done any web development on Linux, and I'm about to start a project that requires it. I love ASP.Net MVC, so what are my availble options on Linux that kind of follow the same principles? The project is a very simple "ecommerce" site (two or three products). There may be other sites to come though that are more complicated. Ruby on Rails comes to mind. Is there something else? Ideas? Thoughts? Pros? Cons? EDIT: Just personal preference, no PHP, Java, or Mono for this project. 回答1:

问题 Is there any way to get a list of currently visible items in QAbstractItemView ? And, if it possible, to receive any notifications about changing of this list. Upd: I'm asking exactly about QAbstractItemView or QTreeView with non-plain structure, not QTableView . Upd2: I'm implementing tree view model with checkboxes. I want next behavior (same for checking/uncheking): If one of checkbox is checked - then all childs must be checked If all child checkboxes are checked - then parent check box

问题 I've got an MVC project, and I want to add Identity to it, but I can't seem to find any good articles on how to do so. Is there an easy way to add Identity to an existing project? I already have a database with stuff in it 回答1: Well, in one respect, you simply have to add the Nuget package and start writing code with it, but I think you're probably talking about all the extras: the pre-written code and samples for doing things like password resets, two-factor auth, etc. For that, no, there's
