      Description copied from class: `UrlBasedViewResolver`
      Creates a new View instance of the specified view class and configures it. Does not perform any lookup for pre-defined View instances.

      Spring lifecycle methods as defined by the bean container do not have to be called here; those will be applied by the `loadView` method after this method returns.

      Subclasses will typically call `super.buildView(viewName)` first, before setting further properties themselves. `loadView` will then apply Spring lifecycle methods at the end of this process.

      Overrides:
        `buildView` in class `UrlBasedViewResolver`
      Parameters:
        `viewName` - the name of the view to build
      Returns:
        the View instance
      Throws:
        `Exception` - if the view couldn't be resolved
      See Also:
        `UrlBasedViewResolver.loadView(String, java.util.Locale)`
