Array types are ignored inside generics in javaType

[kkuo]

I have a json schema that looks like this:

    "properties": {
        "media": {
            "javaType" : "java.util.Map<String,String[]>",
            "type":"object"
        }
}

In 0.4.7 this was generated:

    @JsonProperty("media")
    public Map<String, String[]> getMedia() {
        return media;
    }

In 0.4.8 this was generated:

    @JsonProperty("media")
    public Map<String, String> getMedia() {
        return media;
    }

Ah, GitHub has removed the content between < and > in your schema. (I've updated your formatting).

Yes, I think this is a bug. 0.4.8 now supports nested generics but clearly there is something wrong with array types.

Any idea if we don't want to rely on JavaType to define a map of String to String[], how to do it in plain ole json schema?

The way to achieve this in your schema would be like this:

"properties" : {
  "media" : {
    "type" : "object",
    "additionalProperties" : {
      "type" : "array",
      "items" : {
        "type" : "string"
      }
    }
  }
}

This would imply that the value of media is an object that can have properties with any name but that all their values must be string arrays. This would of course mean that you would have an additional map in your Java:

public class Example {
  private Media media;
  ...
}


public class Media {
  private Map<String, List<String>> additionalProperties = new HashMap<String, List<String>>();
  public Map<String, List<String>> getAdditionalProperties() ...
  public void setAdditionalProperty(String name, List<String> value) ...
}
