In the micro-service architecture, several basic service governance components are needed, including service registration and discovery, service consumption, load balancing, circuit breakers, intelligent routing, configuration management, etc., which are co-organized by these basic components to form a simple microservices system. A brief micro-service system such as:Note: A service and b services can be called each other, when the drawing is forgotten. And the configuration service is also regi

the purpose of development.For these shortcomings, Spring Cloud provides Zuul components to be perfected.The main function of Zuul is routing forwarding and filtering. The routing feature is part of the microservices, such as/api/user forwarding to the User Service, and/api/shop forwarding to the shop service.

In this function, we can implement the custom filtering logic to determine whether to intercept the current request, not to follow the route, or to do some processing after the request route returns the result. Zuul defines four different filter types by default, overwriting an external H

pressure is too high and one instance stops responding, the route transfers traffic to another instance, which is likely to cause all instances of the end to be overwhelmed. In the final analysis, one of the functions of a circuit breaker is to prevent failure or pressure spread. With retry, a circuit breaker can only work if all instances of the service are not operational. At such times, the form of a circuit-breaker is more like providing a friendly error message, or pretending that the serv
