Entity.json(...): how to generate JSON with special characters (like ":") in the JSON key-CodePudding

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?

CodePudding user response：

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;

import com.fasterxml.jackson.annotation.JsonProperty;
import com.fasterxml.jackson.databind.ObjectMapper;

public static void main(String... args) throws IOException {
    MyObject obj = new MyObject();
    obj.name = "Hein Blöd";
    obj.extension = "blah blah";

    String json = new ObjectMapper().writeValueAsString(obj);
    MyObject res = new ObjectMapper().readValue(json, MyObject.class);
}

public static class MyObject {

    @JsonProperty("name")
    private String name;
    @JsonProperty("extension:anybill")
    private String extension;

}
