Is there a class level annotation for jackson
's @JsonProperty
? Without knowing what field names are in the class, I can be able to annotate the class with a annotation and it will map it for me automatically?
Currently I have to annotate each field with a JsonProperty, is there something I can do at the class level that servers the same purpose?
public class myEntity() {
@JsonProperty("banner")
private String banner;
@JsonProperty("menu")
private String menu;
}
The @JsonProperty annotation is used to map property names with JSON keys during serialization and deserialization. By default, if you try to serialize a POJO, the generated JSON will have keys mapped to the fields of the POJO.
@JsonIgnore is used to ignore the logical property used in serialization and deserialization. @JsonIgnore can be used at setters, getters or fields. If you add @JsonIgnore to a field or its getter method, the field is not going to be serialized.
Java Prime Pack @JsonProperty is used to mark non-standard getter/setter method to be used with respect to json property.
The Jackson annotation @JsonCreator is used to tell Jackson that the Java object has a constructor (a "creator") which can match the fields of a JSON object to the fields of the Java object.
@JsonProperty is not class level annotation, and you don't need to mark your class with any annotation. If you provide your class name as an argument to parser it will know how to map it according to your getter methods. It is as if every getter method has been marked with @JsonProperty without any argument
Class level annotation
@JsonRootName("Response")
public class SuperResponse {
...
}
Result:
<Response>
...
</Response>
