This document discusses Spring Boot and Spring Cloud. It provides an overview of how Pivotal enables digital transformation through agile development practices and cloud native platforms. It describes capabilities of Spring Boot like quick project generation and auto configuration. It also discusses how Spring Cloud provides services for microservices like configuration, service registration and discovery, and fault tolerance with circuit breakers. The document includes code samples and demos the creation of a simple Spring Boot application and adding Spring MVC functionality with annotations. It promotes attending hands-on labs to learn how to use Spring Boot and Spring Cloud.

Enhanced Application with Spring Boot
package hello;
import java.util.Arrays;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ApplicationContext;
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(HelloSpringBootApplication.class, args);
}
}
MAGIC!!
• Tags the class as a
source for Spring
Beans
• Asks Boot to
automatically add
beans based on
classpath
• Tell Spring to look for
other components,
configs etc. in the
same package](https://image.slidesharecdn.com/pivotal-springboot-cloudworkshop-160831134100/85/Pivotal-spring-boot-cloud-workshop-12-320.jpg)
