Question

Here is my JSON:

{
  "i": 53691,
  "s": "Something" }

Here is my model:

    public class Test() { 
private int i;
private String s;

    public setInt(int i){ this.i = i; }

    public setString(String s){ this.s = s; }

    // getters here

    }

Here is my class for server’s response:

  public class ServerResponse(){
  private Test;
 public void setTest(Test test){ this.test = test;}
 public Test getTest(){ return Test; } }

When I do:

ObjectMapper mapper = new ObjectMapper();
mapper.readValue(json, serverResponse);

I’m getting an exception like:

JsonProcessingException: Unrecognized field “i” (Class MyClass), not
marked as ignorable

Please advice.

Answer 1

you should make your class members public, or provide getters/setters for them.

in your case it should be:

public void setI() { ... }
public void setS() { ... }

not setInt() and setString()

personally i prefer to make them public — shorter to write and easier to debug.
