WEB Service in Java

Question

I’m creating a Web Service, but I’m having a lot of doubts about how to receive JSON as a parameter.

@Path("WebService/{json}")
@POST
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public String  POST (@PathParam("json") String json) 
{
    return json ;
}

In this code I’m getting the JSON in the URL this way:

http://localhost:8080/IC/webresources/WebService/[   {     "name": "SAM",     "id": 1   },   {     "name": "DEAN",     "id": 2   } ]

That is, there is a JSON in the URL.

That’s the only way I’ve found so far. Someone can give me a light?

Answer 1

Use @FormParam in place of @PathParam.

With this, you can put JSON in the body of the request, since this is a POST.

Answer 2

you do not need to pass the parameters through the URL, since it is a POST.

See the example in this link https://www.mkyong.com/webservices/jax-rs/restfull-java-client-with-java-net-url/ in the POST part.

See that your

@Path("Webservice/{json}")

will be different without json.

I hope I’ve helped.
