【DUBBO】dubbo的registry配置

【一】：配置項

注冊中心地址：zookeeper://ip:端口

<dubbo:registry address="注冊中心的地址" check="啟動時檢查注冊中心是否存在" register="在該注冊中心上服務是否暴露"/>

【二】：配置解析器
-->具體解析器為com.alibaba.dubbo.config.spring.schema.DubboNamespaceHandler配置的com.alibaba.dubbo.config.spring.schema.DubboBeanDefinitionParser、

【三】：配置目標
-->這個配置會想IOC容器中注冊一個bean，該class為com.alibaba.dubbo.config.RegistryConfig
-->這個bean描述當前項目的注冊中心的地址，用戶名,密碼等信息
-->描述的屬性：id,address(注冊中心地址)，username(注冊中心登陸用戶名)，password(注冊中心登陸密碼)，port(注冊中心端口號)，protocol(注冊中心協議)，transporter(注冊中心客戶端實現)，timeout（注冊中心請求超時時間（毫秒）），session（注冊中心會話超時時間（毫秒）），file（動態注冊中心列表存儲文件）
，wait(停止時等候完成通知時間)，check(啟動時檢查注冊中心是否存在)，dynamic(在該注冊中心上注冊是動態的還是靜態的服務)，register（在該注冊中心上服務是否暴露），subscribe(在該注冊中心上服務是否引用),parameters（自定義參數）,isDefault(是否為缺省),server（服務端），client(客戶端)，cluster（集群），group（分組），version（版本）
