request-service-mapping

A ribbon plug-in that supports mapping requests to the target server by configuration.
Only support used with spring-cloud-gateway(version≥2.1.0.RELEASE) and spring-cloud-feign(version≥2.1.0.RELEASE).

client ---request---> service_cluster[service_instance1, service_instance2, service_instance3]
In the above scenario, in spring-cloud, the service instance that ultimately responds to the client request is random by default:
client ---random---> service_instance
After the request-service-mapping is introduced, the specified service instance can be configured to respond to requests from the specified client:
client ---mapped---> service_instance
Configuration template (Match by regular expression):
{"client_ip" : "service_instance_ip"}

Dependency

maven:

<dependency>
  <groupId>io.github.kerwin612</groupId>
  <artifactId>request-service-mapping</artifactId>
  <version>1.1</version>
</dependency>

gradle:

implementation 'io.github.kerwin612:request-service-mapping:1.1'

Configuration

• request.service.mapping
  type: map
  default: {".*": ".*"}
  client and server mapping. In the map, the key is the client ip, the value is the server ip, matched by the regular expression.
• request.service.mapping.short
  type: boolean
  default: false
  whether it matches quickly. If set to true, matching to the first one will not continue matching.
• request.service.mapping.disable
  type: boolean
  default: false
  whether to disable.
• request.service.mapping.client-ip-header
  type: string
  default: __CLIENT_IP__
  the request header key for storing the client IP. After the component obtains the client IP, the client IP is stored in the request header with the request header key.
• request.service.mapping.get-client-ip-headers
  type: array
  default: X-Forwarded-For,Proxy-Client-IP,WL-Proxy-Client-IP,HTTP_CLIENT_IP,HTTP_X_FORWARDED_FOR
  the request header key of get the client IP. This component will preferentially obtain the client IP through this request header key.

By default, just configure request.service.mapping.
