I have a json file which looks like this:

{
    \"ANIMALS\": {
    \"TYPE\": \"MAMMAL\",
    \"COLOR\": \"BLACK\",
    \"HEIGHT\": \"45\",

    }
}

You should implement new naming strategy for your case:

class LowerCaseNamingStrategy extends LowerCaseWithUnderscoresStrategy {

    private static final long serialVersionUID = 1L;

    @Override
    public String translate(String arg0) {
        return arg0.toUpperCase();
    }
}

After that, configure ObjectMapper

ObjectMapper objectMapper = new ObjectMapper();
objectMapper.setPropertyNamingStrategy(new LowerCaseNamingStrategy());
