问题 I have a very simple test case that is using Mockito and Spring Test framework. When I do when(pcUserService.read("1")).thenReturn(pcUser); I get this exception. org.mockito.exceptions.misusing.MissingMethodInvocationException: when() requires an argument which has to be 'a method call on a mock'.

问题 I want to return a simple html page from controller, but I get only the name of the file not its content. Why?

问题 Consider the need to return a plain-text file from a controller method back to the caller. The idea is to have the file downloaded, rather than viewed as plaintext in the browser. I have the following method, and it works as expected. The file is presented to the browser for download, and the file is populated with the string.

问题 I know how to do generic exception handling in Grails using UrlMappings and an ErrorController for generic exception handling, so that if an exception escapes a controller the user will be sent to a generic error page and the exception will be logged. I also know how to use try/catch blocks to handle specific exceptions and attempt to recover from them. But in most controllers, I just want to give the user a slightly more specific error message if an exception occurs. So in the create action,

问题 Look at this Fiddle, what do I have to change, that the expressions in the template get evaluated using the arguments I defined in the HTML? The SAVE-button should call the blabla() -function of the controller, since I pass it? var myApp = angular.module('MyApp',[]) myApp.directive('editkeyvalue', function() { return { restrict: 'E', replace: true, scope: { accept: "expression" }, template : '<div><label class="control-label">{{key}}</label>' + '<label class="control-label">{{key}}</label>' +

问题 I have this route: Route::controller('/', 'PearsController'); Is it possible in Laravel to get the PearsController to load a method from another controller so the URL doesn't change? For example: // route: Route::controller('/', 'PearsController'); // controllers class PearsController extends BaseController { public function getAbc() { // How do I load ApplesController@getSomething so I can split up // my methods without changing the url? (retains domain.com/abc) } } class ApplesController

问题 I want to make an API first application in Laravel. I don't know what is the best approach to do this, I will explain what I am trying to do, but please feel free to give answers how to do this in a different way. I don't want all my frontend to be written in javascript and parse the JSON output of the API with angular.js or something similar. I want my Laravel application to produce the HTML views.

问题 I have a series of Controllers with Request Mappings that match certain URL's. I also want a Controller that will match any other URL not matched by the other Controllers. Is there a way to do this in Spring MVC? For example, could i have a controller with @RequestMapping(value="**") and change the order in which Spring Controllers are processed so this Controller is processed last to catch all unmatched requests? Or is there another way to achieve this behaviour? 回答1: If your base url is

问题 I got a bit of a newbie question. I'm trying to pass a variable from my view to my controller. Is there anyway my method in my controller can receive variables from my view? Post view: show.html.erb: .... <%=link_to "Add relationship", :method => :add_relationship(@rela) %> Controller: post.controller.rb: def add_relationship(rela) @post = Post.find(params[:id]) if current_user.id == @post.user_id @post.rel_current_id = rela.id @post.save redirect_to relationships_url else redirect_to posts

问题 I have a simple Video model in my rails app that has_many comments. I am displaying these comments on the video's show page. When I submit the form everything works fine; however, if there are validation errors on the Comment model, then my system blows up.

Thanks a lot! class CommentsController
