Dubbo3 序列化擴(kuò)展

擴(kuò)展說明

將對(duì)象轉(zhuǎn)成字節(jié)流，用于網(wǎng)絡(luò)傳輸，以及將字節(jié)流轉(zhuǎn)為對(duì)象，用于在收到字節(jié)流數(shù)據(jù)后還原成對(duì)象。

擴(kuò)展接口

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

擴(kuò)展配置

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