Una volta ho avuto questa Domanda Ultime Jersey esempio non funziona risposto, mi imbatto in un altro problema curioso:MediaType.APPLICATION_XML e MediaType.APPLICATION_JSON in un'applicazione demo Jersey
Il server, GET metodi funzionano bene. Ho testato e aggiunto un codice di prova per l'esempio helloworld-pure-jax-rs e in particolare aggiunto una richiesta POST per JSON:
package org.glassfish.jersey.examples.helloworld.jaxrs;
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
@Path("helloworld")
public class HelloWorldResource
{
public static final String CLICHED_MESSAGE = "Hello World!";
@GET
@Produces(MediaType.TEXT_PLAIN)
public String getHello()
{
return CLICHED_MESSAGE;
}
@GET
@Produces(MediaType.APPLICATION_JSON)
public String getHelloJson()
{
return "{ \"message\":" + CLICHED_MESSAGE + "}";
}
@GET
@Produces(MediaType.TEXT_HTML)
public String getHelloHtml()
{
return "<html> " + "<title>" + "Hello Jersey" + "</title>" + "<body><h1>" + CLICHED_MESSAGE
+ "</body></h1>" + "</html> ";
}
@GET
@Produces(MediaType.TEXT_PLAIN)
@Path("/v2")
public String getHello2()
{
return CLICHED_MESSAGE + " v2";
}
@GET
@Produces(MediaType.TEXT_PLAIN)
@Path("/{id}")
public String getHelloId(@PathParam("id") String id)
{
return CLICHED_MESSAGE + " Parameter: " + id;
}
@GET
@Produces(MediaType.TEXT_PLAIN)
@Path("/id/{id : [a-zA-Z][a-zA-Z_0-9]}")
public String getHelloIdId(@PathParam("id") String id)
{
return CLICHED_MESSAGE + " Parameter: " + id;
}
@POST
@Consumes(MediaType.TEXT_PLAIN)
@Produces(MediaType.TEXT_PLAIN)
public Response test(String test)
{
if (test.equals("test"))
return Response.status(400).entity("Error: " + test).build();
return Response.status(200).entity(test).build();
}
@POST
@Path("/test")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public Response testJSON(Test test)
{
String result = "Test JSON created : " + test.getName() + "" + test.getAge();
// return result;
return Response.status(200).entity(result).build();
}
@POST
@Path("/test")
@Consumes(MediaType.APPLICATION_XML)
@Produces(MediaType.APPLICATION_XML)
public Response testXML(Test test)
{
String result = "Test XML created : " + test.getName() + "" + test.getAge();
// return result;
return Response.status(200).entity(result).build();
}
}

Questo funziona bene per il messaggio di pianura posta di testo, ma fpr il JSON (MediaType.APPLICATION_JSON) e XML parte (MediaType.APPLICATION_XML) non riesce a dichiarare non un tipo di supporto supportato. Qualche idea di cosa potrebbe essere sbagliato?
Grazie per la risposta rapida e molto eccellente. Funziona ora. – user2737950
