Question

I want to integrate Spring Boot in one of the existing application. So I decided to start with a POC first. I downloaded a sample working code from http://www.journaldev.com/3531/spring-mvc-hibernate-mysql-integration-crud-example-tutorial and tried to integrate Spring Boot. I changed pom.xml and added a new Java class Application. Below are both of them.

pom.xml

Application.java

package com.journaldev.spring;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;


@EnableAutoConfiguration
@ImportResource("file:/home/gd_java/program_files/projects/SpringMVCHibernate/src/main/webapp/WEB-INF/spring/appServlet/servlet-context.xml")
public class Application {

public static void main(String[] args) {
    ApplicationContext ctx = SpringApplication.run(Application.class, args);
}

}

When I run application it gets deployed without any error. But When I am trying to access it I am getting below error on web browser.

Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
