Question

I created a maven project using rest controller and gave a basic request but it is not hitting the method and gives 404.i am new to the rest controller. So it would be great if someone try to narrow down the issue.
the url : http://localhost:8080/Spring4MVCHelloWorldRestServiceDemo/testrest
HelloController
package com.fis.controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
#RestController
public class HelloController {
#RequestMapping(value="/testrest", method = RequestMethod.GET)
public String welcome() {//Welcome page, non-rest
System.out.println("Test++++++++++++++");
return "Welcome to RestTemplate Example.";
}
/* #RequestMapping("/hello/{player}")
public Message message(#PathVariable String player) {//REST Endpoint.
Message msg = new Message(player, "Hello " + player);
return msg;
}*/
}
HelloInitialization
package com.fis.configuration;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;
public class HelloInitialization extends AbstractAnnotationConfigDispatcherServletInitializer {
#Override
protected Class<?>[] getRootConfigClasses() {
return new Class[] { HelloConfiguration.class };
}
#Override
protected Class<?>[] getServletConfigClasses() {
return null;
}
#Override
protected String[] getServletMappings() {
return new String[] { "/" };
}
}
HelloConfiguration
package com.fis.configuration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
