springfox(swagger2) does not work with GsonHttpMessageConverterConfig

Question

What I am trying to build is a spring-boot (v1.2.3) application and expose my Rest API with SpringFox(swagger2) v2.0.0

my Swagger Spring config

Answer 1

solved the issue by myself:

the issue was with serializing this class:

package springfox.documentation.spring.web.json;

import com.fasterxml.jackson.annotation.JsonRawValue;
import com.fasterxml.jackson.annotation.JsonValue;

public class Json {
  private final String value;

  public Json(String value) {
    this.value = value;
  }

  @JsonValue
  @JsonRawValue
  public String value() {
    return value;
  }
}

to serialize it correct I implemented a SpringfoxJsonToGsonAdapter and added it to my gson config:

adapter:

public class SpringfoxJsonToGsonAdapter implements JsonSerializer {

    @Override
    public JsonElement serialize(Json json, Type type, JsonSerializationContext context) {
        final JsonParser parser = new JsonParser();
        return parser.parse(json.value());
    }
} 

gson config:

@Configuration
public class GsonHttpMessageConverterConfig {

    @Bean
    public GsonHttpMessageConverter gsonHttpMessageConverter() {
        GsonHttpMessageConverter converter = new GsonHttpMessageConverter();
        converter.setGson(gson());
        return converter;
    }

    private Gson gson() {
        final GsonBuilder builder = new GsonBuilder();
        builder.registerTypeAdapter(Json.class, new SpringfoxJsonToGsonAdapter());
        return builder.create();
    }
}
