I create this projet for creating the classic J2EE 'PetStore' using Spring Cloud Spring Cloud is a collection of frameworks that are based on the ease of development of Spring Boot, which simplifies the development of distributed system infrastructure, builds service governance (discovery registration), configuration centers, message buses, load balancing, circuit breakers, Data monitoring, distributed session and cluster state management provide us with the perfect solution for a complete enterprise-class distributed cloud application.

The core of Spring Cloud is service governance. Service governance mainly implements this function by integrating Netflix related products, namely Spring Cloud Netflix, including Eureka for service registration and discovery, circuit breaker with Hystrix, load balancing with Ribbon, Rest client, Feign, Smart Service Routing with Zuul, Spectator, Servo, Atlas for monitoring data collection and display, Archaius for configuration reading, and RxJava for Controller layer Reactive package. In addition, Feign and RxJava are not Netiflix products, but are also integrated into Spring Cloud Netflix.

PetStoreParent ---> General dependencies defined for this project

PetStoreEurekaServer ---> Eureka registration and discovery center

PetStoreDAOCenter ---> Jpa layer which contains all our entities and DAO services

PetStore ---> Eureka service provider which provide one part our our restful web service which will be consumed by PetStoreWeb

PetStoreWeb ---> Frond-end interface and backend which consume PetStore

• Eureka Service registration and discovery
• Eureka Service provider and consumer
• load balancing with Ribbon
• Hystrix for circuit breaker
• Feign for simplifying the http request
• Zuul for its smart Routing Service
