<mvc:annotation-driven/> issues

[viveksrinivasan]

We need to use <mvc:annotation-driven/> in our project to support JSR 303 validations. At the same time we need to extend org.springframework.web.servlet.mvc.annotation.Ann otationMethodHandlerAdapter and override protected HttpInputMessage createHttpInputMessage.

public class AnnotationMethodHandlerAdapter extends org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter 
{
    
	public AnnotationMethodHandlerAdapter() {
		System.out.println("In mY custom handler");
	}
	
	@Override
	protected HttpInputMessage createHttpInputMessage(HttpServletRequest servletRequest) throws Exception {
		return new ServletServerHttpRequest(servletRequest);
	}

   
}

Using <mvc:annotation-driven/> prevents from from doing so. I looked the source code for <mvc:annotation-driven/> (AnnotationDrivenBeanDefinitionParser.java) at it looks like they always create an instance of AnnotationMethodHandlerAdapter which prevents the spring container from using my custom AnnotationMethodHandlerAdapter

Has anyone faced similar issues

Just define the beans yourself and don't use <mvc:annotation-driven/>.

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
    <property name="webBindingInitializer">
        <bean class="org.springframework.web.bind.support.ConfigurableWebBindingInitializer">
            <property name="conversionService" ref="conversionService" />
            <property name="validator" ref="validator" />
        </bean>
    </property>
</bean>

<!-- Configures JSR-303 Declarative Validation with default provider on classpath (Hibernate Validator) -->
<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean"/>

In your config xml file define your custom AnnotationXXXX bean definition before you use <mvc:annotation-driven/> tag. That way it will register your adaptor.
