Change naming of attributes in json without @JsonProperty

Question

I have to convert my json from camelCase to kebab-case.

Example:

My Json:
{
    "disclaimerConfirmed" : true
}

And I need:

{
    "disclaimer-confirmed" : true
}

I cannot use @JsonProperty because it rename this atributes permanently. I am looking for something which will consume Json (can be as String) and returns modified json(as String).

you can also have a look on that (it shows you how to write custom JSON serializers, something that could work for your case), https://stackoverflow.com/questions/12134231/jackson-dynamic-property-names — dZ., Oct 31 '19 at 16:15

You can have different serializers for different cases or you can create pojo with @JsonProperty and use those where-ever required.

For example,

class A {
 private String disclaimerConfirmed;

}

class AkebabCase {
   @JsonProperty("disclaimer-confirmed")
   private String disclaimerConfirmed;
}

So, if you want to serialize to kebab-case you can use converters to convert A to AkebabCase and then serialize.

Jackson supports naming strategies so you could read the input String to map (with camelCase strategy) and then write the map back to a String (with kebab-case which is natively supported );

Specific method you need to switch these conventions in ObjectMapper without annotations is:

mapper.setPropertyNamingStrategy(PropertyNamingStrategy.*);
