4 years ago public ProviderModel lookupExportedService(String serviceKey) { return providers.get(serviceKey); } serviceKey = com.am.dubbo.api.UserInfoApi:1.0.0 而providers里面的key是 com.am.dubbo.api.UserInfoApi 少了版本号，导致获取不到数据，报空指针

4 years ago 2.2.2.RELEASE 要加上 dubbo: config-center: timeout: 50000 registry: timeout: 40000 才能连接上 另外 dubbo.provider.version也失效，需要@Service(version="${dubbo.provider.version}")才行

4 years ago 我也遇到了同样的错误，zookeeper肯定是运行正常的，就是连不上，降到2.7.3就一切正常了。org.apache.dubbo的dubbo-spring-boot-starter比com.alibaba.boot的dubbo-spring-boot-starter连接外部zookeeper要慢不少。
