网络传输扩展
扩展说明
远程通讯的服务器及客户端传输实现。
扩展接口
org.apache.dubbo.remoting.Transporter
org.apache.dubbo.remoting.Server
org.apache.dubbo.remoting.Client
扩展配置
<!-- 服务器和客户端使用相同的传输实现 -->
<dubbo:protocol transporter="xxx" />
<!-- 服务器和客户端使用不同的传输实现 -->
<dubbo:protocol server="xxx" client="xxx" />
<!-- 缺省值设置,当<dubbo:protocol>没有配置transporter/server/client属性时,使用此配置 -->
<dubbo:provider transporter="xxx" server="xxx" client="xxx" />
