擴展說明

將對象轉成字節(jié)流，用于網絡傳輸，以及將字節(jié)流轉為對象，用于在收到字節(jié)流數據后還原成對象。

擴展接口

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

擴展配置

<!-- 協(xié)議的序列化方式 -->
<dubbo:protocol serialization="xxx" />
<!-- 缺省值設置，當<dubbo:protocol>沒有配置serialization時，使用此配置 -->
<dubbo:provider serialization="xxx" />
