核心代码为org.apache.dubbo.registry.zookeeper.ZookeeperRegistry,那以这个为起点进行分析dubbo-registry 类图 来,上源码 属性和构造方法 privatefinalstaticLogger logger = LoggerFactory.getLogger(ZookeeperRegistry.class);/*** 默认zookeeper的跟节点 dubbo*/privatefinalstaticString DEFAULT_ROOT = "dubbo";/*** ...
1 首先模拟了一个简单的demo例子，在这篇经验里有详细。2 然后网上下载zookeeper3410版本，并解压。3 在外部创建如下两个文件夹。4 然后在zookeeper-->conf下看见zoo_sample.cfg，复制该文件粘贴，并重命名为zoo.cfg。5 添加刚才创建的两个文件夹的路径。6 在ProviderHello和ConsumerHello的pom.xml下都加上zkClien...

当设置<dubbo:registry check="false" />时,记录失败注册和订阅请求,后台定时重试。 可通过<dubbo:registry username="admin" password="1234" />设置zookeeper登录信息。 可通过<dubbo:registry group="dubbo" />设置zookeeper的根节点,缺省为dubbo。
三.ZookeeperRegistryFactory 实现了createRegistry方法。这个类有一个成员变量zookeeperTransporter,它是zookeeper客户端的封装,我记得与zookeeper连接有两种方式,一种是用zookeeper提供的包,另一种就是apache.curator.framework这个包,dubbo选用的是后者。 /*** ZookeeperRegistryFactory.* 注册工厂**/publicclassZookeeperRegis...
2 ConcurrentMap<NotifyListener, ChildListener> listeners = zkListeners.get(url);为一个registryDirectory的dubbo监听器和zookeeper上的子节点监听器ChildListener的一对一关系。分别在zookeeper上的routers、configurators、providers节点注册子节点监听器childListener,然后,如果这三个路径中,有节点的子节点发生变化,就会执...
As titled, I tested dubbo-go Nacos and Zookeeper implementation working as registry, metadata, and configcenter in dubbo admin. The changes in this pull request are bugfixes made to different parts that finally make admin work. Sorry, something went wrong. FoghostCn and others added 15 commi...
Dubbo服务启动报错 Zookeeper注册的同时,也会缓存一份Consumer文件列表、写入/pub/.dubbo/dubbo-registry-224.5.6.7.cache 这个文件中,当在同一台机器上启动多台provider的时候,同时启动会出现并发问题、同时创建或者写入该文件,就会出现该问题。 由于是因为文件锁导致的、所以Dubbo配置中做了设置、各自的服务提供者模块...
