Overview

This module extends the functionality of jackson-jr by adding support for (a subset of) Java 8 Date/Time types (value types in JDK java.time package).

Status

Added in Jackson 2.17.

Usage

To be able to use supported annotations, you need to register extension like so:

    private static final JSON JACKSON = JSON.builder()
        .register(new JacksonJrJavaTimeExtension())
        .build();

after which you can use normal read and write operations as usual:

import java.time.LocalDateTime;

public class Application {
    public static void main(String[] args) {
        final LocalDateTime now = LocalDateTime.now();
        MyClass myObject = new MyClass(now, 'Some Other Values....');
        String myObjectJsonString = JACKSON.asString(myObject);
        MyClass myObjectFromJson = JACKSON.beanFrom(MyClass, myObjectJsonString);
        assert myObjectFromJson.getTime().equals(now);
    }
}

// ...

public class MyClass {
    private LocalDateTime time;
    private String otherItems;

    public MyClass(LocalDateTime datetime, String others) {
        //...
    }

    public LocalDateTime getTime() {
        return time;
    }
    // other getters & setters
}

Date Classes currently supported by JacksonJrJavaTimeExtension

• java.time.LocalDateTime

Plans for Future

• Add support for other Java 8 Date/Time types
