[FIXED] Entity.json(...): how to generate JSON with special characters (like ":") in the JSON key

Issue

I have an entity like

@Getter
@Setter
public class MyObject {
  private String name;
  private String extension;
}

I need to generate (for a web service) following JSON:

{
  "name" : "Hein Blöd"
  "extension:anybill" : "blah blah"
}

To generate the JSON I use javax.ws.rs.client.Entity.json(myObject). The problem is the ":" in the second attribute (because ":" is an invalid character for variable names). Is there any annotation to specify the name of attribute key? Or can I rename the generated JSON attribute in any other way?

Solution

I don’t recommend mixing JAX-RS and Jackson. Since you are using javax.ws.rs.client.Entity, you should use @JsonbProperty, which is part of Java EE’s JSON-P and which is intended to work with JAX-RS, on your entity class:

@JsonbProperty("extension:anybill")
private String extension;
