What is Hystrix?In a distributed environment, some unavoidable services fail, and hystrix can control the interaction between distributed services by delaying tolerance and error tolerance logic. Hystrix can isolate service access ingress, suppress

Introduction to Spring Cloud ribbonribbonFor load balancing, and for soft load balancing, the core has three points:
Service discovery, discovering a list of dependent services
Service selection rules, how to select a valid service in multiple services
Service monitoring, detection of failed services, efficient elimination of failure services

. Even if there is a deviation, the reason is well understood. For example, the cost of a standard iPad with Wi-Fi is USD 499/599/699, and the storage capacity is 16/32/64 GB. If you want an iPad with a built-in 3G function, you need to add $130 to the standard iPad price and provide two simple traffic packages: $15 per month, M data traffic is allowed; or 25 USD per month, 2 GB Data traffic is allowed. Easy to select, easy to cancel, no hidden fees, only a few prompts will appear before your da
@ RibbonClients. if you use @ ComponentScan (or @ SpringBootApplication) you need to take steps to avoid it being stored ded (for instance put it in a separate, non-overlapping package, or specify the packages to scan explicitly in the @ ComponentScan ).
WarningFooConfiguration must have @ Configuration, but note that it is not in the @ ComponentScan of the main application context. Otherwise, it will be shared by all @ RibbonClients (that is, the default value of all clients is overwritten ).

Spring Cloud is comprised of a number of sub-projects, such as Spring Cloud Config, Spring Cloud Netflix, Spring Cloud Consul, and more, providing tools commonly used to build distributed systems and microservices, such as configuration management, service discovery, Circuit breakers, intelligent routing, micro-proxies, control buses, one-time tokens, global locks, select Masters, distributed sessions, and cluster status meet all the solutions needed
HTTP and WebSocket, and non-web-friendly protocols that are used internally.The API Gateway can also provide a custom API for each client. Typically, it exposes a coarse-grained API to mobile clients. For example, consider a scenario where product details are considered. The API gateway can provide an endpoint (/PRODUCTDETAILS?PRODUCTID=XXX) that allows the mobile client to obtain all the product details through a single request. API gateways Process requests by invoking individual services (pr

Hystrix is a tool used in microservices for fusing and downgrading.
Purpose: prevent multiple requests from being blocked due to a service call failure or call delay and call failure of multiple requests.

services by invoking multiple microservices. It can be transformed between a Web protocol and a non-web-friendly protocol used internally, such as the HTTP protocol and the WebSocket protocol.
API Gateway can provide a custom API to the client. It exposes a coarse-grained API to mobile clients. Take the product final page of this usage scenario as an example. API Gateway provides a service delivery point (/PRODUCTDETAILS?PRODUCTID=XXX) that enables mobile clients to retrieve all the data from
