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

A couple of things I found missing with the above instructions is the package and imports. When I first tried this, I used my own packages but swagger-ui.html still said there were no packages found. It appears the package is specific.

The classes below are exactly the same as above, but I included the entire class with package names and imports. Registering the adapter is the same as documented above.

First the JSON class

package springfox.documentation.spring.web.json;

import com.fasterxml.jackson.annotation.*;

public class Json {
    private final String value;

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

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

and the adapter class:

package springfox.documentation.spring.web.json;

import java.lang.reflect.Type;

import com.google.gson.*;

public class SpringfoxJsonToGsonAdapter implements com.google.gson.JsonSerializer {

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

}
