Jersey request body needs to be well formed

Question

I have a requirement, where my consumer needs the request to have a well-formed request body.

I am using jersy cleint and below is the code snippet.

SomeRequestObject vSomeRequestObject = getObjectMapper().enable(SerializationFeature.INDENT_OUTPUT).readValue(messageBody,
                            SomeRequestObject.class);

return restClient.target(urlMap.get("uri")).path(urlMap.get("path")).request(MediaType.APPLICATION_JSON)
                .headers(vRequestHeaders).post(Entity.entity(vSomeRequestObject, MediaType.APPLICATION_JSON));
            
            

But somehow the request is still like {"someKey1":"SomeValue1","someKey2":"SomeValue2"}

it should be like below

{
    "someKey1": "SomeValue1",
    "someKey2": "SomeValue2"
}

Please suggest if there is any jackson annotation to do so.

You have to prettify your output. Jackson is able to do it with the writerWithDefaultPrettyPrinter() method. This example below could help :

ObjectMapper objectMapper = new ObjectMapper();
SomeRequestObject object = SomeRequestObject.create();
String json = objectMapper.writerWithDefaultPrettyPrinter().writeValueAsString(object);
System.out.println(json);
