Add the @EnableCircuitBreaker annotation to the main configuration application to enable the circuit-breaker in your project. Let's see the following code:
package com.dineshonjava.customerservice; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.client.circuitbreaker.EnableCircuitBreaker; import org.springframework.cloud.client.loadbalancer.LoadBalanced; import org.springframework.cloud.netflix.eureka.EnableEurekaClient; import org.springframework.context.annotation.Bean; import org.springframework.web.client.RestTemplate; @SpringBootApplication @EnableEurekaClient @EnableCircuitBreaker public class CustomerServiceApplication { public static void main(String[] args) { SpringApplication.run(CustomerServiceApplication.class, args); } ... ... }
I have used the @EnableCircuitBreaker annotation to enable the circuit-breaker pattern in the application. Let's see how to add Hystrix functionalities in the service layer of the application.
