This library adds support for BSON to the Jackson JSON processor.
BSON is a binary representation of JSON. It has gained prominence by its usage as the main exchange and persistence format of the document-oriented database management system MongoDB.
The bson4jackson library integrates completely into Jackson. Please have a look at the Jackson wiki for a complete description. For more information you may also have a look at the bson4jackson tutorial.
The BSON specification defines some additional types not available in the original JSON specification. These types are mapped to simple wrapper objects.
bson4jackson binaries are available from the GitHub Releases page.
You may also use Maven to download bson4jackson:
<dependencies>
<dependency>
<groupId>de.undercouch</groupId>
<artifactId>bson4jackson</artifactId>
<version>2.9.2</version>
</dependency>
</dependencies>If you're using Gradle, you may add the
following snippet to your build.gradle:
dependencies {
compile 'de.undercouch:bson4jackson:2.9.2'
}bson4jackson 2.x is compatible to Jackson 2.x and higher. Due to some compatibility issues, both libraries' major and minor version numbers should match. That means you should use at least bson4jackson 2.1 if you use Jackson 2.1, bson4jackson 2.2 if you use Jackson 2.2, etc. I will try to keep bson4jackson up to date. If there is a compatibility issue I will update it, usually within a couple of days after the new Jackson version has been released.
Here's the compatibility matrix for the current library versions:
| Library | Jackson 2.9.x | Jackson 2.8.x | Jackson 2.7.x | Jackson 2.6.x | Jackson 2.5.x |
|---|---|---|---|---|---|
| bson4jackson 2.9.x | Yes | Yes | Yes | Yes | Yes |
| bson4jackson 2.8.x | Yes | Yes | Yes | Yes | Yes |
| bson4jackson 2.7.x | Yes | Yes | Yes | Yes | Yes |
| bson4jackson 2.6.x | No | No | No | Yes | Yes |
If you're looking for a version compatible to Jackson 1.x, please use bson4jackson 1.3.0. It's the last version for the 1.x branch. bson4jackson 1.3.0 is compatible to Jackson 1.7 up to 1.9.
Execute the following command to compile the library and to run the unit tests:
./gradlew test
The script automatically downloads the correct Gradle version, so you won't have to do anything else. If everything runs successfully, you may create a .jar library:
./gradlew jar
The library will be located under the build/libs directory.
Gradle includes a task that creates all files required to develop bson4jackson in Eclipse. Run the following command:
./gradlew eclipse
Then import the project into your workspace.
Gradle includes a task that creates all files required to develop bson4jackson in IntelliJ. Run the following command:
./gradlew idea
Then import the project into your workspace or open the root bson4jackson.ipr
project file.
