**3. 异常原因：连接远程zookeeper（标记一下，后续再查找详情）**

**3. 解决方法：将远程zookeeper服务替换为本地zookeeper服务，启动运行正常**

**2. 异常背景：启动dobbo服务提供者时，控制台显示异常**

**3. 异常原因：配置redis作为dubbo元数据中心，没有引入相应的jar包**

![20190911154737979.png][]

**4. 解决方法：引入redis相关依赖**

**2. 异常背景：springboot整合dubbo，启动服务提供者报错**

**3. 异常原因：zookeeper中日志包与springboot中日志包冲突**

**4. 解决方法：移除zookeeper中日志相关依赖**
