Triple 可以与 Hessian 一起用吗

duansheli commented 2 years ago

文档里只有 Triple + protobuf 的教程

没看到 Triple 协议 Hessian 序列化方式的例子

可以的，设置对应的序列化类型即可

用的配置

dubbo.protocol.name=tri
dubbo.protocol.serialization=hessian2
dubbo.provider.serialization=hessian2
dubbo.provider.protocol=tri

启动 provider 失败，报错

Extension instance (name: tri, class: interface org.apache.dubbo.rpc.Protocol) couldn't be instantiated: null

protocol 设置成 dubbo 就能正常启动

@duansheli 加一下 protobuf 的依赖

        <dependency>
            <groupId>com.google.protobuf</groupId>
            <artifactId>protobuf-java</artifactId>
            <version>3.14.0</version>
        </dependency>
