NOTES: Spring Cloud feign Ribbon configuration

because Spring Cloud Feign client-side load balancing is through Spring Cloud Ribbon implemented, so we can directly configure the Ribbon client to customize the parameters of each service client invocation.

Global configuration

the method of global configuration is very simple, we can use it directly Ribbon.<key>=<value> to set the ribbon 's default parameters, for example, Modify the default client call timeout example below, using the yml format configuration:

Ribbon

ConnectionTimeout:

ReadTimeout:

Specify the configuration of the service

Most of the cases, Our time-out for service calls may be adjusted based on the characteristics of the actual service, so it is not possible to rely solely on the default configuration, using the spring cloud feign When personalized for each service client and using the spring cloud ribbon < client> for use @feignclient annotated name property or the service name specified by the value attribute, which needs to be case-sensitive, as shown in the following example:

ORG. Lixue. HELLOWORLD:

Ribbon

ConnectionTimeout:

ReadTimeout:
