hystrix configuration spring boot

Hystrix is a library provided by Netflix that helps in adding fault tolerance to your Spring Boot applications. To configure Hystrix in a Spring Boot project, follow these steps:

1. Add the Hystrix dependency to your project's pom.xml file:

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

1. Enable Hystrix in your Spring Boot application by adding the @EnableCircuitBreaker annotation to your application's main class:

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

1. Create a method in one of your service classes that you want to make resilient using Hystrix. Annotate this method with the @HystrixCommand annotation. This annotation tells Hystrix to wrap the method with circuit breaker logic:

@Service
public class YourService {
    @HystrixCommand(fallbackMethod = "fallbackMethod")
    public String yourMethod() {
        // Method implementation
    }

    public String fallbackMethod() {
        // Fallback method implementation
    }
}

1. Configure Hystrix properties in your application.properties or application.yml file. These properties control the behavior of Hystrix, such as timeout values and thread pool settings:

hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=1000
hystrix.threadpool.default.coreSize=10

That's it! You have successfully configured Hystrix in your Spring Boot application. Hystrix will now provide fault tolerance by adding circuit breaker logic to the annotated methods, allowing you to handle failures gracefully.
