Method a: through the configuration and type annotation @Configuration

import org.springframework.beans.factory.annotation.Value;  
import org.springframework.boot.context.embedded.EmbeddedServletContainerFactory;  
import org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContainerFactory;  
import org.springframework.context.annotation.Bean;  
import org.springframework.context.annotation.Configuration;  

@Configuration  
public class MyConfiguration {  

    @Value("${tomcatport:8090}")  
    private int port;  

    @Bean  
    public EmbeddedServletContainerFactory servletContainer(){  
        return new TomcatEmbeddedServletContainerFactory(this.port);  
    }  
}

Use @Value comment for tomcatport given port 8090.
