Specifying a View when using jackson2 #649
Description
Hey,
I just came across this generator, and it seems to be mostly what I was needing.
But in my Java project I'm making use of com.fasterxml.jackson.annotation.View for Jackson2, that means I can generate different JSON data from the same object – depending on the context I am in.
I have looked into the docs but so far did not find if I could possibly specify a View that should be used. Any idea?
Example
My views:
public class Views {
public static class BaseConfig {
}
public static class REST {
}
public static class Exclude {
}
}
Sample of a persistent class that is also used in JSON communication:
package foo.bar;
import com.fasterxml.jackson.annotation.JsonView;
@Data
@Entity
public class SomeClass
{
@Id
@JsonView({Views.BaseConfig.class, Views.REST.class})
private Integer id;
@JsonView({Views.BaseConfig.class, Views.REST.class})
private Integer parentID;
@JoinColumn(name = "parentID", insertable = false, updatable = false)
@ManyToOne(targetEntity = SomeClass.class, fetch = FetchType.LAZY)
@JsonView(Views.Exclude.class) // @JsonIgnore would be an alternative for this
private SomeClass parent;
@Column(length = 32, nullable = false)
@JsonView({Views.REST.class})
private String someProperty;
@Column(length = 32, nullable = false)
@JsonView({Views.BaseConfig.class})
private Long anotherProperty;
}
I then configure an ObjectMapper as follows for the JSON mapping on my REST API.
ObjectMapper mapper = new ObjectMapper();
mapper.setConfig(mapper.getSerializationConfig().withView(Views.REST.class));
