Sebastien Deleuze b0e1e66b7f Add CORS support ...

This commit introduces support for CORS in Spring Framework.

Cross-origin resource sharing (CORS) is a mechanism that allows
many resources (e.g. fonts, JavaScript, etc.) on a web page to
be requested from another domain outside the domain from which
the resource originated. It is defined by the CORS W3C
recommandation (http://www.w3.org/TR/cors/).

A new annotation @CrossOrigin allows to enable CORS support
on Controller type or method level. By default all origins
("*") are allowed.

@RestController
public class SampleController {

	@CrossOrigin
	@RequestMapping("/foo")
	public String foo() {
		// ...
	}
}

Various @CrossOrigin attributes allow to customize the CORS configuration.

@RestController
public class SampleController {

	@CrossOrigin(origin = { "http://site1.com", "http://site2.com" },
				 allowedHeaders = { "header1", "header2" },
				 exposedHeaders = { "header1", "header2" },
				 method = RequestMethod.DELETE,
				 maxAge = 123, allowCredentials = "true")
	@RequestMapping(value = "/foo", method = { RequestMethod.GET, RequestMethod.POST} )
	public String foo() {
		// ...
	}
}

A CorsConfigurationSource interface can be implemented by HTTP request
handlers that want to support CORS by providing a CorsConfiguration
that will be detected at AbstractHandlerMapping level. See for
example ResourceHttpRequestHandler that implements this interface.

Global CORS configuration should be supported through ControllerAdvice
(with type level @CrossOrigin annotated class or class implementing
CorsConfigurationSource), or with XML namespace and JavaConfig
configuration, but this is not implemented yet.
