Implement Config Server


Add dependency

<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-config-server</artifactId></dependency>


Create Config Server

@SpringBootApplication@EnableConfigServerpublic class ConfigServerApplication { public static void main(String[] args) { SpringApplication.run(ConfigServerApplication.class, args); }}

👈


Configure Config Server

spring.cloud.config.server.git.uri=https://github.com/making/metflix-config.git

Configure Config Client


Add dependency

<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-config</artifactId></dependency>


Configure Config Client

spring.cloud.config.uri=http://localhost:8888spring.application.name=membership


Implement Service Registry


Add dependency

<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-eureka-server</artifactId></dependency>


Create Eureka Server@SpringBootApplication@EnableEurekaServerpublic class EurekaServerApplication { public static void main(String[] args) { SpringApplication.run(EurekaServerApplication.class, args); }}

👈


Configure Discovery Clients


Add dependency

<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-eureka</artifactId></dependency>


Create Eureka Client

@SpringBootApplication@EnableDiscoveryClientpublic class RecommendationsApplication { public static void main(String[] args) { SpringApplication.run(RecommendationsApplication.class, args); }}

👈


Introduce Circuit Breaker


Add dependency

<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-hystrix</artifactId></dependency>


Use Hystrix@SpringBootApplication@EnableDiscoveryClient@EnableCircuitBreakerpublic class RecommendationsApplication { public static void main(String[] args) { SpringApplication.run(RecommendationsApplication.class, args); }}

👈


Configure Hystrix Command@Componentpublic class RecommendationsService { @HystrixCommand(fallbackMethod = "recommendationFallback") List<Movie> findRecommendationsForUser(String user) { // some recommendation logic } List<Movie> recommendationFallback(String user) { return top5Movies; }}

👈


Configure Hystrix Command@Componentpublic class RecommendationsService { @HystrixCommand(fallbackMethod = "recommendationFallback") List<Movie> findRecommendationsForUser(String user) { // some recommendation logic } List<Movie> recommendationFallback(String user) { return top5Movies; }}
