/**
* Provides support for enabling and configuring JSON.
*
* Besides enabling JSON, the API also allows customization of the JSON format
* produced and consumed with JAXB beans.
* Such customization requires that an implementation of
* {@link javax.ws.rs.ext.ContextResolver} returns a configured
* {@link com.sun.jersey.api.json.JSONJAXBContext} instance.
*
*
For example, if the following two JAXB beans are defined:
*
* @XmlRootElement
* public class BeanOne {
* public String name;
* public int number;
* }
*
* @XmlRootElement
* public class BeanTwo {
* public List<String> titles;
* }
*
*
* And the following resource class uses the above JAXB beans:
*
*
* @Path("beans")
* public class MyResource {
*
* @GET @Path("one") @Produces(MediaType.APPLICATION_JSON)
* public BeanOne getOne() {
* BeanOne one = new BeanOne();
* one.name = "Howard";
* one.number = 3;
* return one;
* }
*
* @GET @Path("two") @Produces(MediaType.APPLICATION_JSON)
* public BeanTwo getTwo() {
* BeanTwo two = new BeanTwo();
* two.titles = new ArrayList<String>(1){{add("Title1");}};
* return two;
* }
*
*
*
* Then, for the URI path beans/one
, the following JSON will be
* produced:
*
* {"name":"Howard","number":"3"}
*
* However, it might be required that the JSON object named number
have
* a non-String value 3
.
*
* And, for the URI path beans/two
, the following JSON will be
* produced:
*
* {"titles":"Title1"}
*
* However, it might be required that the JSON object named titles
* have a JSON array value ["Title1"]
,
* since the titles
field on the JAXB bean BeanTwo
* represents an array, thus enabling consuming of such JSON values the same way on
* the client side no matter how many elements the array contains.
*
* The {@link com.sun.jersey.api.json.JSONJAXBContext} may be configured to enable
* such required production of JSON as described above in the following manner:
*
* @Provider
* public final class JAXBContextResolver implements ContextResolver<JAXBContext> {
*
* private final JAXBContext context;
*
* private final Set<Class> types;
*
* private final Class[] cTypes = {BeanOne.class, BeanTwo.class};
*
* public JAXBContextResolver() throws JAXBException {
* this.context = new JSONJAXBContext(JSONConfiguration.natural().build(), cTypes);
* this.types = new HashSet(Arrays.asList(cTypes));
* }
*
* public JAXBContext getContext(Class<?> objectType) {
* return (types.contains(objectType)) ? context : null;
* }
* }
*
*
* Then, the produced JSON would become: {"name":"Howard","number":3}
* and {"titles":["Title1"]}
respectively for the URI paths
* beans/one
and beans/two
. Please note, that you do not need
* to configure this in much detail. Using {@link com.sun.jersey.api.json.JSONConfiguration.Notation#NATURAL} notation
* means that Jersey JSON processor will autamatically take care about numbers, booleans and arrays. This notation
* will probably become the default one for Jersey in one of the future releases.
*
* For a complete set of supported properties, see
* {@link com.sun.jersey.api.json.JSONConfiguration.Builder}.
