### Integration with Jackson ObjectMapper (jackson-databind)

msgpack-java supports serialization and deserialization of Java objects through [jackson-databind](https://github.com/FasterXML/jackson-databind).
For details, see [msgpack-jackson/README.md](https://github.com/msgpack/msgpack-java/blob/develop/msgpack-jackson/README.md). The template-based serialization mechanism used in v06 is deprecated.

Two artifacts are published depending on which Jackson major version your project uses:

| Jackson version | Artifact | Requirements |
| --- | --- | --- |
| Jackson 2.x | [`jackson-dataformat-msgpack`](https://github.com/msgpack/msgpack-java/blob/develop/msgpack-jackson/README.md) | Java 8+ |
| Jackson 3.x | [`jackson-dataformat-msgpack-jackson3`](https://github.com/msgpack/msgpack-java/blob/develop/msgpack-jackson3/README.md) | Java 17+ |

Use `jackson-dataformat-msgpack` if your project still depends on Jackson 2.x, or `jackson-dataformat-msgpack-jackson3` if you've upgraded to Jackson 3.x. See each module's README for install instructions and usage details.
