Spring 3 Annotations

Question

I can't get spring annotations to work at all, I'm just trying to get the simplest thing to work...

.../mycontext/something -> invokes method:

@RequestMapping(value = "/something")
@ResponseBody
public String helloWorld() {
    System.out.println("hello world");
    return "Hello World";
}

My main problem is no matter how hard I try, I can't find a complete SIMPLE example of the configuration files needed, every spring tutorial is filled with junk, I just one one controller to handle a request with a mapping and can't get it to work

does anyone know of a simple and complete spring example. pet-clinic is no good, it's way too complicated, I have a tiny basic use case and it's proving to be a real pain to get working (this always happens with Spring)

Answer 1

You should try Spring Roo. It will generate a simple Spring application for you using simple commands and then you can incrementally extend it. It is a great tool for learning Spring as well as for rapid application development.

You can also find several examples of Spring 3.0 MVC framework at https://src.springframework.org/svn/spring-samples/

I'd recommend you checkout some of projects from here :

http://www.springbyexample.org/maven/site/spring-by-example-util/1.2/source-repository.html

and try going trough book spring in action(manning) they give very good example on how to use aspects

or refer to this post :

Hello, the absolute simplest alternative if you're familiar with Eclipse is to use SpringSource Tool Suite (Eclipse plugins)

This product has a tcServer bundled inside.

By default, STS will start with "dashboard" page in the editor window. From here, you can click on creating a controller as demonstrated by this screenshot:

This is a quite simple controller and all you have to do to get it deployed on the bundled tcServer (Tomcat with some extra management features) is to click "next" a few times in the wizard.

That's a very good starting point for doing your own testing!
