Dubbo+Zookeeper報錯KeeperException$UnimplementedException: KeeperErrorCode = Unimplemented
阿新 • • 發佈：2018-12-02
今天在執行spring-boot + dubbo的時候，zookeeper中註冊的時候丟擲一個異常，檢視到我使用的curator-recipes版本是4.0+版本，依賴的zookeeper是3.5加版本，而我自己的zookeeper是3.4.x版本。
異常資訊

說是由於Zookeeper版本問題，果然我的Zookeeper版本是3.4.x的
檢視到我的pom依賴的zookeeper是3.5.x所以導致這個錯誤
更新版本
<dependency> <groupId>org.apache.curator</groupId> <artifactId>curator-recipes</artifactId> <version>4.0.1</version> 先排除zookeeper <exclusions> <exclusion> <groupId>org.apache.zookeeper</groupId> <artifactId>zookeeper</artifactId> </exclusion> </exclusions> </dependency> 新增zookeeper3.4.x版本 <dependency> <groupId>org.apache.zookeeper</groupId> <artifactId>zookeeper</artifactId> <version>3.4.7</version> </dependency>
修改依賴之後重新執行成功。
