Jersey RESTfull service with JSON

Question

I want to parse the values from the JSON-Post into Java-Variables. But they are always empty!

JSON-Post:

{\"algID\":0,\"vertices\":[1,2,3]}


        

Answer 1

You need to create a POJO that Jersey can serialize the JSON to:

import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement
public class MyPojo {
    public int algID;
    public int[] verticies;

    public MyPojo() {} // constructor is required

}

Then ...

@POST
@Consumes(MediaType.APPLICATION_JSON)
@Path("getCloseness_vertices")
public String getCloseness_vertices(MyPojo p) 
{
    int i = p.algID;
}

Also you need to include the jersey-json jar file.
