Spring and reflection

[10Ways]

Is Spring or in partifular Spring.Core, basically just reflection plus some .confgi file?

Plese correct me if is actually more than that.

So spring.core is basically doing in C/C++, stuff like function pointer or callback function, or in Win32 things like LoadLibary, right?

You can find answer to a similar question in a following thread:

http://forum.springframework.net/viewtopic.php?t=87

I believe it should answer your question as well.

that was a very comprehensive post, but I am still a bit confuse as to how u can do service location without using IApplicationContext and stuff in the code snippet of the post u showed. I mean, if i can really do that, that would b neat.

Hi,

In the case of the Spring's web support - a custom handler is registered with asp.net and it is responsible for retrieving the objects from the application context for you based on the http request. That is how the example Aleks showed in the previous post works (in brief) w/o using the service locator approach. If you are writing a .NET remoting application then your SAO objects would be described in the standard Spring.NET config file and are created as a result of creating the application context in your startup code. The SAO objects themselves would have their properties set and references to collaborating objects set via Spring without having to use a service locator. I've found when writing a winform application - where you are more exposed to the use of raw 'new' (as compared to the standard infrastructure of asp.net) you tend to use a service locator more frequently in response to creating objects to user actions. This could be hidden via the use of a Spring winform base class but then your object is coupled to spring. As we delve deeper into DI usage in winforms we will have a better idea what the best design practices are in that area. Hope this helps.

Cheers,
Mark

is there a asp.net web app sample out there that does this?

Hiya

There will be one in place for the forthcoming 1.0 release... but there is not one in place right now.

So what are your views on petshops?

However, some quick n short same that highlight Spring's main features, or points tat stands out. would be necessary also, so, u know, people like me can pick up quickly.

for my current project, i decided to stick with just Reflection and some config files. As Spring.NET is not tat well documented yet. While Reflection, i can copy from tons on examples. As for the master page feature. I suppose I can get buy with the Basepage/LoadControls way to do things while waiting for VS 2005.

Anyway, hope there are more docs when 1.0 comes out

Hiya

An example application that demonstrates all of the IOC Dependency Injection features of Spring.NET will be available in the 1.0 release, which is scheduled for release on the 31st of July (ten days).

Yeah, the documentation is quite light on examples, this is being worked on.

Ciao
