About Zuul
Zuul includes the two most important functions of request routing and filtering:
The routing function is responsible for forwarding external requests to specific microservice instances, which is the basis for achieving a unified access to external access, and the filter function is responsible for intervening in the processing of requests, and is the basis for implementing request verification, service aggregation and other functions .
Zuul and Eureka are integrated to register Zuul itself as an application under Eureka service governance, and at the same time obtain information about other microservices from Eureka, that is, after accessing microservices, they are obtained after Zuul jumps.
Note: The Zuul service will eventually be registered in Eureka
Zuul provides three functions: proxy + routing + filtering
Routing access mapping rules
Basic rules
No routing
http://localhost:8001/dept/get/2
Enable routing
http://myzuul.com:9527/microservicecloud-dept/dept/get/2
Equivalent to routing ip: routing port / specific microservice name / request path of the microservice
It turned out to be a specific microservice ip: specific microservice port / request path of the microservice
Set agent name
Replace the specific name of the microservice in the address to prevent others from discovering the name
before
http://myzuul.com:9527/microservicecloud-dept/dept/get/2
zuul:
routes:
mydept.serviceId: microservicecloud-dept
mydept.path: /mydept/**
after
http://myzuul.com:9527/mydept/dept/get/1
Ignore the real service name

Both http://myzuul.com:9527/microservicecloud-dept/dept/get/2 and http://myzuul.com:9527/mydept/dept/get/1
