Jackson serializer for primitive types

Question

I am writing a custom serializer to convert double values into strings in JSON objects. My code so far:

public String toJson(Object obj) throws IOException {         


        

Answer 1

You can do it with custom serializer, but there is a simpler way to. Enable JsonGenerator.Feature.WRITE_NUMBERS_AS_STRINGS:

mapper.getFactory().enable(JsonGenerator.Feature.WRITE_NUMBERS_AS_STRINGS);
