Feign source code analysis

GitHub github = Feign.builder()
                         .decoder(new GsonDecoder())
                         .target(GitHub.class, "https://api.github.com");

public interface GitHub {
    

  @RequestLine("GET /repos/{owner}/{repo}/contributors")
  List<Contributor> contributors(@Param("owner") String owner, @Param("repo") String repository);

  class Contributor {
    
    String login;
    int contributions;
  }
}

It will generate Github Implementation class of interface , Let's find out

1）Feign.builder() Meeting new Out Feign An inner class feign.Feign.Builder;
2） adopt target Method , Package parameters as Target class , And then there was build Method


Top handle Contract Class into ParseHandlersByName in , Last new a
Feign Implementation class of interface
