public static Feign.Builder builder()

configKey

public static String configKey(Class targetType,
                               Method method)

Configuration keys are formatted as unresolved see tags. This method exposes that format, in case you need to create the same value as MethodMetadata.configKey() for correlation purposes.

Here are some sample encodings:

 

   
 Route53: would match a class  route53.Route53
   
 Route53#list(): would match a method  route53.Route53#list()
   
 Route53#listAt(Marker): would match a method 
 route53.Route53#listAt(Marker)
   
 Route53#listByNameAndType(String, String): would match a method 
 route53.Route53#listAt(String, String)
 
 

Note that there is no whitespace expected in a key!

Parameters:

targetType - type of the Feign interface.

method - invoked method, present on type or its super.
