Ignoring properties

In some cases, you may need to ignore some Java object properties from being displayed in the resulting JSON string; they may be non-primary properties holding temporary values, or some internal attributes that will not be interesting to the JSON consumer party. Hence, the @JsonbTransient annotation is used to hide some Java attributes from being shown in the resulting JSON, as shown in the following examples:

public class Movie { 
 
    private long id; 
    private String title; 
    @JsonbTransient 
    private int productionYear; 
 
    // setters and getters here 
} 
 
JsonbConfig config = new JsonbConfig().withFormatting(true); 
Jsonb jsonb = JsonbBuilder.create(config); 
 
Movie movie = new Movie(); 
movie.setId(15); 
movie.setTitle("Beauty and The Beast"); 
movie.setProductionYear(2017); 
 
String json = jsonb.toJson(movie); 
System.out.println(json); 

By running the previous example, the output will be as follows:

{ 
    "id": 15, 
    "title": "Beauty and The Beast...
