sending POJO to save on server using RESTful webservices - web-services

Question

I am developing a Restful web service which allow user to set all parameters in POJO and send it to server side web service, then web service will store this data and return generated Id back to client. But my POJO has parent-child relationship that contain set of POJO, So how can I do this using RESTful web service. I also written a code to fetch data from server using web service and its working fine. But for this issue please help me.
Thanks.

I am not sure if I understood your question correctly. I guess some sample code will help. If you are using RestTemplate then serializing and deserializing will be done for you automatically. RestTemplate uses Jackson to parse JSON so you don't need to worry about parent/child relationship in your POJO.
So here is an example. There are 1000's of examples out there on internet. Thats how I learnt.
RestTemplate restclient = new RestTemplate();
Product product = restclient.getForObject(url,Product.class);
System.out.println(product.getCoupons().getName());
Where as product is (I completely made this up myself),
public class Product {
#JsonProperty("id")
private String id;
#JsonProperty("coupons")
private Coupons coupons;
#JsonProperty("id")
public String getId() {
return id;
}
#JsonProperty("id")
public void setId(String id) {
this.id = id;
}
#JsonProperty("coupons")
public Coupons getCoupons() {
return coupons;
}
#JsonProperty("coupons")
public void setCoupons(Coupons coupons) {
this.coupons = coupons;
}
}
public class Coupons {
#JsonProperty("name")
private String name;
#JsonProperty("name")
public String getName() {
return name;
}
#JsonProperty("name")
public void setName(String name) {
this.name = name;
}
}
Let me know if I misunderstood your question, I can update my answer accordingly.
