The projection for converting a string field to JSONObject using default method as below works fine:
public interface ResponseProjection {
@JsonIgnore
@Value("#{target.extraData}")
String getExtras();
default JSONObject getExtraData() {
return new Gson().fromJson(getExtras(), JSONObject.class);
}
}
whereas, while using open projection like below?
public interface ResponseProjection {
@Value("#{java(new GsonBuilder().disableHtmlEscaping().create().fromJson(target.extraData, JSONObject.class))}")
JSONObject getExtraData();
}
throws error:
w.s.m.s.DefaultHandlerExceptionResolver : Resolved [org.springframework.http.converter.HttpMessageNotWritableException: Could not write JSON: EL1003E: A problem occurred whilst attempting to construct an object of type 'GsonBuilder' using arguments '()'; nested exception is com.fasterxml.jackson.databind.JsonMappingException: EL1003E: A problem occurred whilst attempting to construct an object of type 'GsonBuilder' using arguments '()' (through reference chain: com.sun.proxy.$Proxy162["extraDataDto"]->com.sun.proxy.$Proxy166["extraData"])]
Is there a way to parse jsonString to json using Gson using open projection?
