接收InputStream并从Jersey中的json字符串获取值

Question

How can I received JSON string from the InputStream in Jersey, which was sent from HttpURlConenction in android, and how can I get the values of it to store them into database table?

{
 "latitude":93.86898451,
  "longitude":30.66561387,
  "time":"24.04.2015 11:11:05",
  "route":4
}

Jersey receiver class:

@Path("data")
public class Receiver {



    @POST
    @Consumes({MediaType.APPLICATION_JSON, "text/json"})
    public void storeDate() {
        BufferedReader in
           = new BufferedReader(new InputStreamReader(process.getInputStream()));


    }

}

With Jersey you should be able to just declare class Data (with Jackson annotations to support deserialization from JSON):

public class Data {
    private double latitude;
    private double longitude;
    private String time;
    private int route;

    @JsonCreator
    public Data(@JsonProperty("latitude") double latitude, 
                @JsonProperty("longitude") double longitude, 
                @JsonProperty("time") String time, 
                @JsonProperty("route") int route) {
        this.latitude = latitude;
        this.longitude = longitude;
        this.time = time;
        this.route = route;
    }

    public double getLatitude() {
        return latitude;
    }

    public double getLongitude() {
        return longitude;
    }

    public String getTime() {
        return time;
    }

    public int getRoute() {
        return route;
    }
}

and then define your endpoint as:

@Path("/data")
public class Receiver {

    @POST
    @Consumes(MediaType.APPLICATION_JSON)
    public Response storeData(Data data) {
        // do something with data

        return Response.status(201).build();
    }    
}

and it should just work.

1) If you can modify the client code add this line in your HttpURLConnection connection

    connection.setRequestProperty("Content-Type", "application/json");

This will convert the input to a POJO

2)If you cannot edit the client HttpUrlConnection the bring in the stream as

    @Consumes("{*/*}")
    public Something (String request){
        ObjectMapper mapper = new ObjectMapper();
        Data data = mapper.readValue(request, Data.class);

        return = getSomething(data);
    }
