Issue in running springboot MVC project

Question

when trying to run my first HelloWorld app with springBoot and Tomcat Embeded I get the following exception :

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read candidate component class nested exception is java.lang.IllegalStateException: Could not evaluate condition on org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration$EmbeddedDatabaseConfiguration due to org/springframework/dao/DataAccessException not found. Make sure your own configuration does not rely on that class. This can also happen if you are @ComponentScanning a springframework package (e.g.
if you put a @ComponentScan in the default package by mistake)

Here is my entry point Example class config:

@SpringBootApplication
public class Example extends SpringBootServletInitializer
{
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) 
    {
        return application.sources(Example.class);
    }

    public static void main(String[] args) throws Exception 
    {
        SpringApplication.run(Example.class, args);
    }
}

Here is my WelcomeController class:

package controler;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import java.util.Map;

@Controller
public class WelcomeController 
{
    // inject via application.properties
    @Value("${welcome.message:test}")
    private String message = "Hello World";

    @RequestMapping("/")
    public String welcome(Map<String, Object> model) 
    {
        model.put("message", this.message);
        return "welcome";
    }
}

Here is my pom.xml

Do you have the data source defined in the application properties file? — Rahul Kargwal, Feb 13 '18 at 13:10
@RahulKargwal there is no data source in my properties file i have just : spring.mvc.view.prefix: /WEB-INF/jsp/ spring.mvc.view.suffix: .jsp welcome.message: Hello World — A.Java, Feb 13 '18 at 13:14
There seem to be other files that are not posted here, is that the case? Probably you have defined data source or another bean in any other file? — Rahul Kargwal, Feb 13 '18 at 13:28
@RahulKargwal absolutly not i just want to make this tutorial : https://www.mkyong.com/spring-boot/spring-boot-hello-world-example-jsp/ — A.Java, Feb 13 '18 at 13:40
