Spring MVC - unable to deploy war in AWS

I have built a sample spring app following the tutorial. Everything works as expected when i run the application locally in tomcat but when i deploy the application on AWS ...it fails

here is AppConfig.java class

package com.akash.lab2;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;


/**
 * Created by akash on 08/11/16.
 */

@Configuration
@EnableAutoConfiguration
@ComponentScan
public class AppConfig extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application){
        return application.sources(applicationClass);
    }

    public static void main(String args[]){
        SpringApplication.run(applicationClass,args);
    }

    private static Class<AppConfig> applicationClass = AppConfig.class;
}

Dataconfig.java 

package com.akash.lab2.config;

import org.apache.tomcat.dbcp.dbcp2.BasicDataSource;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.core.env.Environment;
import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.Resource;
import org.springframework.orm.hibernate5.LocalSessionFactoryBean;

import javax.sql.DataSource;

/**
 * Created by akash on 11/12/16.
 */
@Configuration
@PropertySource("classpath:app.properties")
public class DataConfig {

    @Autowired
    private Environment env;

    @Bean
    public LocalSessionFactoryBean sessionFactory(){
        Resource config = new ClassPathResource("hibernate.cfg.xml");
        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
        sessionFactory.setConfigLocation(config);
        sessionFactory.setPackagesToScan(env.getProperty("lab2.entity.package"));
        sessionFactory.setDataSource(dataSource());
        return sessionFactory;
    }

    @Bean
    public DataSource dataSource() {

        BasicDataSource ds = new BasicDataSource();

        //Driver class name
        ds.setDriverClassName(env.getProperty("lab2.db.driver"));

        //Set the Url
        ds.setUrl(env.getProperty("lab2.db.url"));

        //set username
        ds.setUsername(env.getProperty("lab2.db.username"));

        //set password
        ds.setPassword(env.getProperty("lab2.db.password"));

        return ds;
    }
}

gradle build file

group 'com.akash'
version '1.0-SNAPSHOT'

buildscript{
    repositories{
        mavenCentral()
    }
    dependencies{
        classpath 'org.springframework.boot:spring-boot-gradle-plugin:1.4.1.RELEASE'
    }
