Annotation Interface JsonPropertyOrder
@Target({ANNOTATION_TYPE,TYPE,METHOD,FIELD})
@Retention(RUNTIME)
public @interface JsonPropertyOrder
Annotation that can be used to define ordering (possibly partial) to use
when serializing object properties. Properties included in annotation
declaration will be serialized first (in defined order), followed by
any properties not included in the definition.
Annotation definition will override any implicit orderings (such as
guarantee that Creator-properties are serialized before non-creator
properties)
Examples:
// ensure that "id" and "name" are output before other properties @JsonPropertyOrder({ "id", "name" }) // order any properties that don't have explicit setting using alphabetic order @JsonPropertyOrder(alphabetic=true)
This annotation may or may not have effect on deserialization: for basic JSON handling there is no effect, but for other supported data types (or structural conventions) there may be.
NOTE: annotation is allowed for properties mostly to support
alphabetic ordering of Map
entries.
