@Jacksonized

@Jacksonized was introduced as experimental feature for @Builder and @SuperBuilder in lombok v1.18.14.

Support for @Accessors was added in lombok v1.18.40.

Overview

The @Jacksonized annotation is an add-on annotation for @Builder, @SuperBuilder, and @Accessors.

For @Accessors(fluent = true) on a type, it automatically configures Jackson to use the generated setters and getters for (de-)serialization by inserting @JsonProperty annotations. (Note that @Jacksonized @Accessors on fields are not supported.)

@Jacksonized @Accessors(fluent = true)
@Getter @Setter
public class AccessorsExample {
	private int age = 10;
}
		

For @Builder and @SuperBuilder, it automatically configures the generated builder class to be used by Jackson's deserialization. It only has an effect if present at a context where there is also a @Builder or a @SuperBuilder; a warning is emitted otherwise.

Without @Jacksonized, you would have to customize your builder class(es). With @Jacksonized, you can simply write something like this to let Jackson use the generated builder:

@Jacksonized @Builder
@JsonIgnoreProperties(ignoreUnknown = true)
public class JacksonExample {
	private List<Foo> foos;
}

This annotation does not change the behavior of the generated builder. A @Jacksonized @SuperBuilder remains fully compatible to regular @SuperBuilders.
