The aspect is a singleton object and is created outside the Spring container. A solution with XML configuration is to use Spring’s factory method to retrieve the aspect. <bean id=”syncLoggingAspect” class=”uk.co.demo.SyncLoggingAspect” factory-method=”aspectOf” /> With this configuration the aspect will be treated as any other Spring bean and the autowiring will work as normal. You have … Read more
A few pointers: Debunking myths: proxies impact performance (have a look at the comments too) Java theory and practice: Decorating with dynamic proxies Benchmarking the cost of dynamic proxies
I understand your confusion and it took me some time to understand how these concepts were related together. So here is my (somehow personal) explanation of all this: 1. Inversion of Control Inversion of control is a design principle rather generic that refers to the decoupling of the specification of a behavior from when it … Read more
That’s what middleware is for: app.use(function(req, res, next) { if (!req.headers.authorization) { return res.status(403).json({ error: ‘No credentials sent!’ }); } next(); }); …all your protected routes… Make sure that the middleware is declared before the routes to which the middleware should apply.
I don’t think there is built in attribute for ajax, but you can create your own AjaxOnly filter like this: public class AjaxOnlyAttribute : ActionMethodSelectorAttribute { public override bool IsValidForRequest(ControllerContext controllerContext, System.Reflection.MethodInfo methodInfo) { return controllerContext.RequestContext.HttpContext.Request.IsAjaxRequest(); } } And decorate your action methods like this: [AjaxOnly] public ActionResult AjaxMethod() { } See Also: ASP.NET MVC … Read more
It looks like RealProxy won’t come to .NET Core/Standard. In the issue, a Microsoft developer suggests DispatchProxy as an alternative. Also, some existing AOP frameworks may support .NET Core already or in the future (as seen in the comments on the question). An alternative is the DispatchProxy, which has a wonderful example here: http://www.c-sharpcorner.com/article/aspect-oriented-programming-in-c-sharp-using-dispatchproxy/. If … Read more
As long as you have control of your AOP I think it’s efficient. We did have performance problems anyway, so by own reasoning we were not fully in control 😉 This was mostly because it’s important that anyone that writes aspects has full understanding of all the other aspects in the system and how they … Read more
Just to get your head around it: It is the ability to hook events such as: creation of objects, setting of properties, etc, and attach general functions to them, that will be populated with relevant context. Because C# doesn’t have an inbuilt facility for this, you need a framework, like PostSharp, to do ‘bytecode weaving’ … Read more
You can test a Spring Aspect by creating a proxy programatically: MyInterface target = new MyClass(); AspectJProxyFactory factory = new AspectJProxyFactory(target); MyAspect aspect = new MyAspect(arg); factory.addAspect(aspect); MyInterface proxy = factory.getProxy(); … then you can call methods on proxy, and make assertions about aspect, proxy and target.
