Update documentation with example of single ApplicationContext per webapp [SPR-11703]

[spring-projects-issues]

Oleksandr Gavenko opened SPR-11703 and commented

If read docs there are no info about where allowed to put mvc:annotation-driven annotation (in application context config vs servlet context).

There are some question on StackOverflow and Spring Forum about this.

http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd

http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd

have text: Configures the annotation-driven Spring MVC Controller programming model. Note that, with Spring 3.0, this tag works in Servlet MVC only!

And for String 3.2.5 - @RequestHandler is not mapped if mvc:annotation-driven put to servlet context config . But I look to latest petclinic:

https://github.com/spring-projects/spring-petclinic/blob/master/src/main/resources/spring/mvc-core-config.xml

https://github.com/spring-projects/spring-petclinic/blob/master/src/main/webapp/WEB-INF/web.xml

and seems that mvc:annotation-driven now allowed in servlet context!

So as minimum comment in http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd should be fixed.

And as maximum this behavior should be documented in http://docs.spring.io/spring/docs/4.0.3.RELEASE/spring-framework-reference/htmlsingle/#mvc-config-enable

<mvc:annotation-driven /> xsd documentation has been updated, as well as reference documentation to provide more guidance about where this element should be located.
