In Spring 3.0 you should use simple classes annotated by Controller . Such controller can handle more than one request. Each request is handles by its own method.
This methods are annotated by RequestMapping .

Bear in mind that wile the deprecated stuff still works in Spring 3, the Spring guys are much more aggressive in removing deprecated APIs than the JavaSE people, i. E they actually will remove them. – skaffman Jan 19 '11 at 11:01.
In Spring 3.0 you should use simple classes annotated by @Controller. Such controller can handle more than one request. Each request is handles by its own method.
This methods are annotated by @RequestMapping. On think you need to rethink is the fact, that a old school SimpleFormController handle a lot of different requests (min: one to get the form and a second to submit the form). You have to handle this now by hand.
But belive me it is eayser. For example this Controller in REST Style, will handle two requests: /book - POST: to create a book /book/form - GET: to get the form for creation Java Code: @RequestMapping("/book/**") @Controller public class EtfController { @RequestMapping(value = "/book", method = RequestMethod. POST) public String create( @ModelAttribute("bookCommand") final BookCommand bookCommand) { if (bookCommand == null) { throw new IllegalArgumentException("A bookDt is required"); } Book book = createBookFromBookCommand(bookCommand); return "redirect:/book/" + book.getId(); } @RequestMapping(value = "/book/form", method = RequestMethod.
GET) public String createForm(final ModelMap modelMap) { modelMap. AddAttribute("all", "what you need"); return "book/create"; //book/create. Jsp } }.
Cheers. Annotaing mapping is all new to me as I was following this book I got amazon.co. Uk/Spring-Action-Craig-Walls/dp/1933988134/… – jonney Jan 19 '11 at 14:39 quick question.
Does that mean I no longer have to map my controllers into beans via xml files? – jonney Jan 19 '11 at 15:17 @jonney: Yes, there are new Annotations: @Controller, @Service, @Repository, as well as @Autowire and @Inject. But you have to enable something that is called component scan in your xml.
- Have a look at the SpringSource blog (around end of 2009) and the new features section of the Spring reference. -- You are also free to ask a new question. – Ralph Jan 19 '11 at 15:30 awsome.
This way is definitely easier! I'l have a look at the other annotations in spring. – jonney Jan 19 '11 at 15:59.
Annotated POJOs can act as controllers; see @Controller.
Grr, you were first :-) – Sean Patrick Floyd Jan 19 '11 at 10:43.
In Spring 3.0, your Controllers should no longer inherit from a base class. The standard way is to use annotated controllers.
– jonney Jan 19 '11 at 15:29 @jonney exactly. The XML way to do it is not even documented anymore in the Spring 3 Reference. – Sean Patrick Floyd Jan 19 '11 at 15:33 what about for DI and aspects?
All can be defined using annotations now? Is there any need to write any spring bean anymore lol? – jonney Jan 20 '11 at 9:40 @jonney there are ApplicationContext implementations that don't need XML at all, e.g. AnnotationConfigApplicationContext.
But usually, some XML is required (and with Springsource Tool Suite, managing the XML is actually fun) – Sean Patrick Floyd Jan 20 '11 at 9:48.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
