Using namespace in JsonProperty annotation

[birolozturkk]

Hi guys I am trying to deserialise my yaml file. I am using @JsonProperty to specify namespace in the fields in my POJO class but this does not work.
I don't want to create a wrapper class for each namespace, do you have a suggestion?

language: tr #supported tr, en
database:
  driver: "SQLITE" #MYSQL, SQLITE
  host: "localhost"
  database: "database"
  username: ""
  password: ""
  port: 3306
  useSSL: false

@Data
public class Config {

    private String language;

    @JsonProperty("database.driver")
    private String driver;
    @JsonProperty("database.host")
    private String host;
    @JsonProperty("database.database")
    private String database;
    @JsonProperty("database.username")
    private String username;
    @JsonProperty("database.password")
    private String password;
    @JsonProperty("database.port")
    private int port;

    @JsonProperty("database")
    private boolean useSSL;
}

First of all, since this is YAML-specific, will move to YAML repo.

I am not quite sure what you mean by "namespace" here: in XML it has specific meaning, but I am not aware of "namespace" as a concept in YAML (excluding use of expressing, f.ex, Kubernetes Namespaces in YAML content which is application specific).

Do you just mean a name prefix to use? This is not something something @JsonProperty.namespace will do; it will be ignored for YAML.

In general, to troubleshoot issues like this you should probably try serializing a POJO with content to see what output looks like, and whether structure matches. This helps figure out why deserialization won't work.

In this particular case, you should probably consider creating separate Database class to get proper nesting.

yes creating another class is a solution but if I had such a possibility I would like to use it

Understood. Unfortunately the way you were hoping to use @JsonProperty does not (and will not) work. So trying to suggest alternatives.
