Spring Boot exclude Tomcat server and hibernate validator?

Question

Question seems repeated but I facing some issue, when I am following below configuration from this spring boot war without tomcat embedded to Exclude embedded tomcat server
I am using Spring-Web in JOB to call Rest Service using Rest Template.

            <!-- Spring Dependencies -->
    <dependency>

    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-commons</artifactId>
    </dependency>
</dependencies>

And here is my main method configuration

@SpringBootApplication
@ComponentScan("com.mypackage")
@PropertySource("classpath:config.properties")
@PropertySource("classpath:app_Config.properties")
@EnableAutoConfiguration(exclude = { DataSourceAutoConfiguration.class })
public class FileUploadToWCM { ...}

Below error occurring me, when I am trying to exclude tomcat dependancy

Please let me know, if you need more information.

Well, you have everything that is required to start a web application except that you removed the embedded server. If you write a client application, don't use spring-boot-starter-web at all. I'd include spring-web instead and be done with it.

Right now, your project is actually embedding the full Spring MVC stack (the full server if you will). That's probably not what you want.

Spring Boot exclude Tomcat server and hibernate validator?
