protobuf-jackson

Overview

This library provides support for JSON serialization for protobuf objects.

Unfortunately standard library provided by google requires both gson and guava libraries and this may be an overkill for certain projects that already depend on jackson.

So, if your project already has a dependency on new jackson library and you need JSON support for protobuf, this library is for you!

How to use

Add to dependencies in your pom.xml

<dependency>
  <groupId>com.truward.protobuf</groupId>
  <artifactId>protobuf-jackson</artifactId>
  <version>1.0.0</version>
</dependency>

Then in java code:

// serialization
try (JsonGenerator jg = jsonGenerator($yourOutputStream)) {
  ProtobufJacksonUtil.writeJson($yourProtobufInstance, jg);
}

// deserialization
try (JsonParser jp = jsonParser($yourInputStream)) {
  ProtobufJacksonUtil.readJson($YourProtobufModel.class, jp);
}
