FearX :
I have the QueueContent class that it has is a superclass of two others.
I get a String in JSON format that contains the information I need to extract. The super class is:
@Data
@JsonIgnoreProperties(ignoreUnknown = true)
public class QueueContent {
private String empresa;
private String empresa_cor;
private String empresa_contato;
private String empresa_url;
private String empresa_telefone;
private String empresa_idioma;
public QueueContent(String empresa, String empresa_cor, String empresa_contato, String empresa_url, String empresa_telefone, String empresa_idioma) {
this.empresa = empresa;
this.empresa_cor = empresa_cor;
this.empresa_contato = empresa_contato;
this.empresa_url = empresa_url;
this.empresa_telefone = empresa_telefone;
this.empresa_idioma = empresa_idioma;
}
public QueueContent() {
}
}
I'm using Lombok to generate Getters / Setters)
This is the child class:
@Data
public class EmailCameraOffline extends QueueContent {
private Timestamp camera_last_online;
private String camera_nome;
private String empresa_url_plataforma;
public EmailCameraOffline(String empresa, String empresa_cor, String empresa_contato, String empresa_url, String empresa_telefone, String empresa_idioma, Timestamp camera_last_online, String camera_nome, String empresa_url_plataforma) {
super(empresa, empresa_cor, empresa_contato, empresa_url, empresa_telefone, empresa_idioma);
this.camera_last_online = camera_last_online;
this.camera_nome = camera_nome;
this.empresa_url_plataforma = empresa_url_plataforma;
}
public EmailCameraOffline() {
}
}
So I've done:
EmailCameraOffline infosEmail = new ObjectMapper().readValue(content, EmailCameraOffline.class); System.out.println(infosEmail);
And the output is:
EmailCameraOffline (camera_last_online = 2020-03-12 03: 01: 45.0, camera_nome = Pier Cam 1, empresa_url_platform = null)
How do I get my EmailCameraOffline object to have the superclass attributes initialized?
hradecek :
Everything should be loaded and initialized just fine, so calling:
System.out.println(infosEmail.getEmpresa());
should give expected value.
Problem
The problem is in the default implementation of toString() method (done via @Data) at EmailCameraOffline class, which does not include inherited fields.
Solution
To fix this you can "override" @Data's toString() implementation to include inherited fields as well using Lombok as:
@Data
@ToString(callSuper = true)
public class EmailCameraOffline extends QueueContent {
...
}
