How to Use Protobuf and JSON Serialization in the Context of the Triple Protocol

1 Introduction

Protobuf (Protocol Buffers) is a lightweight and efficient data interchange format developed by Google, used for the serialization, deserialization, and transmission of structured data. Compared to text formats like XML and JSON, Protobuf has smaller data sizes, faster parsing speeds, and better scalability.

2 Usage

When using Protobuf (IDL) to develop triple communication services, the Dubbo server will automatically enable support for protobuf and protobuf-json serialization modes.

2.1 Add Dependencies

To use the triple + protobuf mode, the following dependencies must be added:

1 Introduction

The triple protocol implemented by Dubbo offers better usability (not binding Protobuf), allowing developers to directly define services using Java interfaces. For users expecting a smooth upgrade, with no multilingual services, or unfamiliar with Protobuf, the Java interface approach is the simplest way to use triple.

The following details the underlying serialization specifics in this protocol model: the framework will wrap the request and response using a built-in protobuf object, which means the object will be serialized twice. The first serialization is done using the method specified by serialization=hessian, and the second is to wrap the byte[] serialized in the first step with the protobuf wrapper before transmission.
