<!-- If you need to report a security issue please visit https://github.com/apache/dubbo/security/policy --> - [ ] I have searched the [issues](https://github.com/apache/dubbo/issues) of this repository and believe that this is not a duplicate. ### Environment * Dubbo version: 3.0.6 * Operating System version: macos 12.3 * Java version: 17 ### Steps to reproduce this issue 1. use config like this: ```yaml dubbo: metadata-report: address: ${spring.redis.host:127.0.0.1} protocol: redis port: ${spring.redis.port:6379} ``` the config of meta-report like this: ```xml <dubbo:metadata-report address="127.0.0.1" protocol="redis" port="6379" /> ``` 3. The behavior of starting application will be failed. 4. by the way,when we use config like this: ```yaml dubbo: metadata-report: address: redis:${spring.redis.host:127.0.0.1}:${spring.redis.port:6379} ``` We can start application successfully. the config of meta-report like this: ```xml <dubbo:metadata-report address="redis:127.0.0.1:6379" port="6379" /> ``` ### Expected Behavior <!-- What do you expect from the above steps？--> parse protocol from ```dubbo.metadata-report.protocol``` property when we cannot parse form url parameters ### Actual Behavior dubbo metacenter support cannot parse protocol from url parameters,so it use default value```org.apache.dubbo.common.constants.CommonConstants#DEFAULT_DIRECTORY``` <!-- What actually happens? --> ```dubbo.metadata-report.protocol```cannot be applied,application start failed If there is an exception, please attach the exception trace: ``` java.lang.IllegalStateException: No such extension org.apache.dubbo.metadata.report.MetadataReportFactory by name dubbo, no related exception was found, please check whether related SPI module is missing. at org.apache.dubbo.common.extension.ExtensionLoader.findException(ExtensionLoader.java:747) ~[dubbo-3.0.6.jar:3.0.6] at org.apache.dubbo.common.extension.ExtensionLoader.createExtension(ExtensionLoader.java:754) ~[dubbo-3.0.6.jar:3.0.6] at org.apache.dubbo.common.extension.ExtensionLoader.getExtension(ExtensionLoader.java:548) ~[dubbo-3.0.6.jar:3.0.6] at org.apache.dubbo.common.extension.ExtensionLoader.getExtension(ExtensionLoader.java:523) ~[dubbo-3.0.6.jar:3.0.6] at org.apache.dubbo.metadata.report.MetadataReportFactory$Adaptive.getMetadataReport(MetadataReportFactory$Adaptive.java) ~[dubbo-3.0.6.jar:3.0.6] at org.apache.dubbo.metadata.report.MetadataReportInstance.init(MetadataReportInstance.java:96) ~[dubbo-3.0.6.jar:3.0.6] at org.apache.dubbo.metadata.report.MetadataReportInstance.init(MetadataReportInstance.java:78) ~[dubbo-3.0.6.jar:3.0.6] at org.apache.dubbo.config.deploy.DefaultApplicationDeployer.startMetadataCenter(DefaultApplicationDeployer.java:290) ~[dubbo-3.0.6.jar:3.0.6] at org.apache.dubbo.config.deploy.DefaultApplicationDeployer.initialize(DefaultApplicationDeployer.java:189) ~[dubbo-3.0.6.jar:3.0.6] at org.apache.dubbo.config.deploy.DefaultModuleDeployer.prepare(DefaultModuleDeployer.java:467) ~[dubbo-3.0.6.jar:3.0.6] at org.apache.dubbo.config.spring.context.DubboConfigApplicationListener.initDubboConfigBeans(DubboConfigApplicationListener.java:71) ~[dubbo-3.0.6.jar:3.0.6] at org.apache.dubbo.config.spring.context.DubboConfigApplicationListener.onApplicationEvent(DubboConfigApplicationListener.java:57) ~[dubbo-3.0.6.jar:3.0.6] at org.apache.dubbo.config.spring.context.DubboConfigApplicationListener.onApplicationEvent(DubboConfigApplicationListener.java:35) ~[dubbo-3.0.6.jar:3.0.6] at org.springframework.context.event.SimpleApplicationEventMulticaster.doInvokeListener(SimpleApplicationEventMulticaster.java:176) ~[spring-context-5.3.16.jar:5.3.16] at org.springframework.context.event.SimpleApplicationEventMulticaster.invokeListener(SimpleApplicationEventMulticaster.java:169) ~[spring-context-5.3.16.jar:5.3.16] at org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent(SimpleApplicationEventMulticaster.java:143) ~[spring-context-5.3.16.jar:5.3.16] at org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent(SimpleApplicationEventMulticaster.java:131) ~[spring-context-5.3.16.jar:5.3.16] at org.springframework.context.support.AbstractApplicationContext.registerListeners(AbstractApplicationContext.java:881) ~[spring-context-5.3.16.jar:5.3.16] at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:580) ~[spring-context-5.3.16.jar:5.3.16] at org.springframework.boot.web.servlet.context.ServletWebServerApplicationContext.refresh(ServletWebServerApplicationContext.java:145) ~[spring-boot-2.6.4.jar:2.6.4] at org.springframework.boot.SpringApplication.refresh(SpringApplication.java:740) ~[spring-boot-2.6.4.jar:2.6.4] at org.springframework.boot.SpringApplication.refreshContext(SpringApplication.java:415) ~[spring-boot-2.6.4.jar:2.6.4] at org.springframework.boot.SpringApplication.run(SpringApplication.java:303) ~[spring-boot-2.6.4.jar:2.6.4] at org.springframework.boot.SpringApplication.run(SpringApplication.java:1312) ~[spring-boot-2.6.4.jar:2.6.4] at org.springframework.boot.SpringApplication.run(SpringApplication.java:1301) ~[spring-boot-2.6.4.jar:2.6.4] ``` -- This is an automated message from the Apache Git Service.
