Add mvc namespace for simplifying setup of Spring MVC [SPR-6306] #10972
Description
Keith Donald opened SPR-6306 and commented
Spring MVC setup could be simplified considerably by adding a custom XML namespace. A simple tag to configure mvc:annotated-controllers/ with reasonable default settings would be a great start.
Example benefits:
AFTER MVC NAMESPACE
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
<mvc:annotation-driven/>
</beans>
BEFORE MVC NAMESPACE
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
<!-- HANDLER MAPPING RULES -->

<!-- REGISTERED HANDLER TYPES -->

</property>
</bean>
<!-- FIELD TYPE CONVERSION AND VALIDATION -->

<!-- Configures JSR-303 Declarative Validation with default provider on classpath (Hibernate Validator) -->
