February 9, 2020 admin Web Development 0. Currently, the @HystrixCommand annotation will not work with the Reactive Web Service applications, we have to use the HystrixCommands class to solve our problems. Worse than failures, these applications can also result in increased latencies between services, which backs up queues, threads, and other system resources causing even more cascading failures across the system. So, Eureka handles the configuration of the servers that are calling, and Ribbon handles the load balancing and Feign handles the actual code. Also using Hystrix, we can define what we want to do when the primary service call is not available. Traffic going through the underlying service use role-based access control to invite users into certain (! . Please see the below example: Before the application is running, what you would see in your codebase are the interfaces annotated with the @FeignClient.
