niejian opened a new issue #8709:
URL: https://github.com/apache/dubbo/issues/8709


   - [x] I have searched the [issues](https://github.com/apache/dubbo/issues) 
of this repository and believe that this is not a duplicate.
   - [x] I have checked the 
[FAQ](https://github.com/apache/dubbo/blob/master/FAQ.md) of this repository 
and believe that this is not a duplicate.
   
   ### Environment
   
   * Dubbo version: 3.0.2.1
   * Operating System version: macos
   * Java version: 1.8
   * springboot version: 2.1.7
   * zk-server version: 3.4.14
   * `curator` version: 4.2.0/4.0.2
   * `zk-client` version: 3.4.14
   
   ### Steps to reproduce this issue
   本地环境,debug模式启动没问题,非debug模式启动就提示`zookeeper not connected`
   参照:https://github.com/apache/dubbo/issues/5378 
,不管是在配置文件中添加超时时间还是在连接地址上添加timeout参数都无效。
   配置信息:
   ```properties
   spring.application.name=demo-3.0
   server.port=9988
   dubbo.application.name=${spring.application.name}
   dubbo.protocol.port=20881
   dubbo.scan.base-packages=cn.com.dubbo.demo.provider.service
   dubbo.registry.protocol=dubbo
   dubbo.registry.timeout=60000
   
#dubbo.registry.address=zookeeper://192.168.240.15:2181|nacos://192.168.240.53:8848
   
dubbo.registry.address=zookeeper://192.168.240.58:2182?timeout=60000|zookeeper://192.168.240.15:2181?timeout=60000
   #dubbo.registry.address=zookeeper://localhost:2181
   dubbo.application.logger=log4j2
   #dubbo.config-center.address=zookeeper://127.0.0.1:2181
   #dubbo.metadata-report.address=zookeeper://127.0.0.1:2181
   dubbo.config-center.timeout=60000
   dubbo.config-center.address=zookeeper://192.168.240.58:2182?timeout=60000
   dubbo.metadata-report.address=zookeeper://192.168.240.58:2182?timeout=60000
   dubbo.metadata-report.timeout=60000
   # 可选值 interface、instance、all,默认是 all,即接口级地址、应用级地址都注册
   dubbo.application.register-mode=all
   #dubbo.application.service-discovery.migration=FORCE_APPLICATION
   # FORCE_INTERFACE,只消费接口级地址,如无地址则报错,单订阅 2.x 地址
   # APPLICATION_FIRST,智能决策接口级/应用级地址,双订阅
   # FORCE_APPLICATION,只消费应用级地址,如无地址则报错,单订阅 3.x 地址
   dubbo.application.service-discovery.migration=APPLICATION_FIRST
   ```
