We are writing some simple jersey services written in groovy that return basic lists of objects and are getting different results between json and xml.
Here is our Person model
@XmlAccessorType( XmlAccessType.FIELD )
@XmlRootElement
class Person {
String name
}
Here is our Service
@GET
@Produces(["application/json", "application/xml"])
public List<Person> getPersons() {
return Manager.getPersons()
}
For XML this returns what we want:
<persons>
<person>
<name>James</name>
</person>
</persons>
But for JSON the named array is singular which is not what we want:
{"person": ["name": "James"]}
So to get around the JSON response not having a plural named array we introduced the Persons model object:
@XmlAccessorType( XmlAccessType.FIELD )
@XmlRootElement
class Persons {
List<Person> persons
}
We update our Service to:
public Persons getPersons()
The result is now JSON has the correct plural named array, but the XML response now has duplicate persons elements, which is not what we want.
<persons>
<persons>
<name>James</name>
</persons>
</persons>
So it appears that we can't get consistent results for XML and JSON. Ideally I'd love not to have to create a Persons object. In fact I think the easiest thing would be to support an annotation on the Service that lets us define the root element. Something like this:
@GET
@Produces(["application/json", "application/xml"])
@XmlRootElement(name="persons")
public List<Person> getPersons() {
return Manager.getPersons()
}
