Title Body

Problem I have a Spring MVC application that requires me to translate the id's and names of a list of a certain entity to an array of JSON objects with specific formatting, and output that on a certain request. That is, I need an array of JSON objects like this: { label: Subject.getId() value: Subject.getName() } For easy use with the jQuery Autocomplete plugin. So in my controller, I wrote the following: @RequestMapping(value = "/autocomplete.json", method = RequestMethod.GET) @JsonSerialize(contentUsing=SubjectAutocompleteSerializer.class) public @ResponseBody List<Subject> autocompleteJson() { return Subject.findAllSubjects(); } // Internal class public class SubjectAutocompleteSerializer extends JsonSerializer<Subject> { @Override public void serialize(Subject value, JsonGenerator jgen, SerializerProvider provider) throws IOException, JsonProcessingException { jgen.writeStartObject(); jgen.writeStringField("label", value.getId().toString()); jgen.writeStringField("value", value.getName()); jgen.writeEndObject(); } } The JSON I get back however, is the default serialization inferred by Jackson. My custom serializer seems to be completely ignored. Obviously the problem is incorrect usage of @JsonSerialize or JsonSerializer, but I could not find proper usage of these within context anywhere. Question What is the proper way to use Jackson to achieve the serialization I want? Please note that it's important that the entities are only serialized this way in this context, and open to other serialization elsewhere
