Spring AnnotationHandlerMapping not working - spring

Question

I'm new to spring controllers using annotated controllers.
Here is my configuration
Bean definition
<bean
class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />
Controller
package learn.web.controller.annotation;
import javax.servlet.http.HttpServletRequest;
import learn.web.controller.BaseController;
import org.springframework.context.support.ReloadableResourceBundleMessageSource;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
#Controller
public class FirstController extends BaseController {
#RequestMapping("/annotation/first.ftl")
public ModelAndView first(HttpServletRequest request) {
if(messageSource instanceof ReloadableResourceBundleMessageSource){
ReloadableResourceBundleMessageSource m = (ReloadableResourceBundleMessageSource) messageSource;
m.clearCache();
}
messageSource.getMessage("learn.message.first", new Object[] {},
localResolver.resolveLocale(request));
return new ModelAndView("/annotation/first");
}
}
When tried to access the given URL Spring is throwing a warning org.springframework.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/Learn/annotation/first.ftl] in DispatcherServlet with name 'springapp'

Answer 1

I think what you are missing is the component scan
<context:component-scan base-package="learn.web.controller" />
Add this to your configuration and try.
This will load all annotated components from the specified package
Your configuration may look like this
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-2.5.xsd">
<context:component-scan base-package="learn.web.controller" />
<bean
class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />
</beans>
