序列化扩展

扩展说明

将对象转换为字节流进行网络传输，并将字节流转换为对象以将字节流数据恢复为对象。

扩展点

  • org.apache.dubbo.common.serialize.Serialization
  • org.apache.dubbo.common.serialize.ObjectInput
  • org.apache.dubbo.common.serialize.ObjectOutput

扩展配置

<!-- Protocol serialization method -->
<dubbo:protocol serialization="xxx" />
<!-- Default value setting, when <dubbo:protocol> does not configure serialization, use this configuration -->
<dubbo:provider serialization="xxx" />

已知扩展

  • org.apache.dubbo.common.serialize.dubbo.DubboSerialization
  • org.apache.dubbo.common.serialize.hessian.Hessian2Serialization
  • org.apache.dubbo.common.serialize.java.JavaSerialization
  • org.apache.dubbo.common.serialize.java.CompactedJavaSerialization
