• what’s JsonSerializer?
• what’s Module?
• how to work by ObjectMapper?

//参考springfox源码
public class Swagger2JacksonModule extends SimpleModule implements JacksonModuleRegistrar {
  public Swagger2JacksonModule() {
  }

  public void maybeRegisterModule(ObjectMapper objectMapper) {
    if (objectMapper.findMixInClassFor(Swagger.class) == null) {
      objectMapper.registerModule(this);
      objectMapper.configure(SerializationFeature.FAIL_ON_EMPTY_BEANS, false);
    }
  }

}

//自定义序列化
