Serialization protocol

Edit
Update time: 2024-04-10

When using the Bolt communication protocol, SOFARPC can choose different serialization protocols, which can be hessian2 or protobuf currently.

By default, SOFARPC uses hessian2 as the serialization protocol. If you need to set the serialization protocol to protobuf, you need to configure the following settings when publishing the service:

<sofa:service ref="sampleService" interface="com.alipay.sofarpc.demo.SampleService">
    <sofa:binding.bolt>
        <sofa:global-attrs serialize-type="protobuf"/>
    </sofa:binding.bolt>
</sofa:service>

That is to add the <sofa:global-attrs> tag to the <sofa:binding.bolt> tag and set the serialize-type attribute to protobuf.

Correspondingly, when referencing the service, you also need to change the serialization protocol to protobuf. The setting method is similar to publishing the service:

<sofa:reference interface="com.alipay.sofarpc.demo.SampleService" id="sampleServiceRef" jvm-first="false">
    <sofa:binding.bolt>
        <sofa:global-attrs serialize-type="protobuf"/>
    </sofa:binding.bolt>
</sofa:reference>

Currently, when you use Annotation for service reference, it is not yet supported to set serialization protocol. But this will be supported in future versions. For details, see ISSUE: https://github.com/sofastack/sofa-boot/issues/278
