chaoyoung opened a new issue, #11767:
URL: https://github.com/apache/dubbo/issues/11767
### Environment
* Dubbo version: 3.1.6
* Operating System version: MacOS 13.2.1
* Java version: 1.8.0_362
### Steps to reproduce this issue
1. provider和consumer在同一个应用中
2. application配置`dubbo.registry.address =
nacos://${spring.cloud.nacos.server-addr}?username=${spring.cloud.nacos.username}&password=${spring.cloud.nacos.password}&&namespace=${spring.cloud.nacos.discovery.namespace}`
3. 实际参数spring.cloud.nacos.server-addr=10.20.0.100:8848,
spring.cloud.nacos.username='', spring.cloud.nacos.password='',
spring.cloud.nacos.discovery.namespace=''
4. 运行时`dubbo.registry.address`解析为
`nacos://10.20.0.100:8848?username=&password-&namespace=`
5. dubbo会将此url参数解析为username=username, passowrd=password, namespace=namespace
### Expected Behavior
Dubbo service register successful
### Actual Behavior
Dubbo service register failed, then application exit.
