duyang416 opened a new issue, #13737: URL: https://github.com/apache/dubbo/issues/13737
环境： ``` dubbo 3.2.10 jdk 1.8 spring-cloud-alibaba 2021.0.5.0 spring-cloud 2021.0.5 nacos 2.2.3 ``` 项目需要使用dubbo协议+protobuf序列化的组合，根据官网文档[here](https://cn.dubbo.apache.org/zh-cn/overview/mannual/java-sdk/reference-manual/serialization/protobuf/)，在配置文件中加入了如下配置： ```yaml dubbo: protocol: name: dubbo port: -1 serialization: protobuf ``` 但是在项目启动时提示如下错误： ```java java.lang.IllegalStateException: No such extension protobuf for serialization/org.apache.dubbo.common.serialize.Serialization at org.apache.dubbo.config.utils.ConfigValidationUtils.checkMultiExtension(ConfigValidationUtils.java:712) at org.apache.dubbo.config.utils.ConfigValidationUtils.checkMultiExtension(ConfigValidationUtils.java:689) at org.apache.dubbo.config.utils.ConfigValidationUtils.validateProtocolConfig(ConfigValidationUtils.java:603) at org.apache.dubbo.config.utils.DefaultConfigValidator.validate(DefaultConfigValidator.java:38) at org.apache.dubbo.config.context.AbstractConfigManager.checkDefaultAndValidateConfigs(AbstractConfigManager.java:620) at org.apache.dubbo.config.context.ConfigManager.checkConfigs(ConfigManager.java:302) at org.apache.dubbo.config.context.ConfigManager.loadConfigs(ConfigManager.java:282) at org.apache.dubbo.config.deploy.DefaultApplicationDeployer.loadApplicationConfigs(DefaultApplicationDeployer.java:255) at org.apache.dubbo.config.deploy.DefaultApplicationDeployer.initialize(DefaultApplicationDeployer.java:222) at org.apache.dubbo.config.deploy.DefaultModuleDeployer.prepare(DefaultModuleDeployer.java:635) at org.apache.dubbo.config.spring.context.DubboConfigApplicationListener.initDubboConfigBeans(DubboConfigApplicationListener.java:85) at org.apache.dubbo.config.spring.context.DubboConfigApplicationListener.init(DubboConfigApplicationListener.java:68) at org.apache.dubbo.config.spring.context.DubboConfigApplicationListener.onApplicationEvent(DubboConfigApplicationListener.java:59) at org.apache.dubbo.config.spring.context.DubboConfigApplicationListener.onApplicationEvent(DubboConfigApplicationListener.java:38) at org.springframework.context.event.SimpleApplicationEventMulticaster.doInvokeListener(SimpleApplicationEventMulticaster.java:178) at org.springframework.context.event.SimpleApplicationEventMulticaster.invokeListener(SimpleApplicationEventMulticaster.java:171) at org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent(SimpleApplicationEventMulticaster.java:145) at org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent(SimpleApplicationEventMulticaster.java:133) at org.springframework.context.support.AbstractApplicationContext.registerListeners(AbstractApplicationContext.java:892) at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:588) at org.springframework.boot.web.servlet.context.ServletWebServerApplicationContext.refresh(ServletWebServerApplicationContext.java:147) at org.springframework.boot.SpringApplication.refresh(SpringApplication.java:732) at org.springframework.boot.SpringApplication.refreshContext(SpringApplication.java:409) at org.springframework.boot.SpringApplication.run(SpringApplication.java:308) at org.springframework.boot.SpringApplication.run(SpringApplication.java:1300) at org.springframework.boot.SpringApplication.run(SpringApplication.java:1289) at org.xxx.XXXApplication.main(XXXApplication.java:26) ``` 刚开始接触dubbo，希望能提供一下具体的使用文档或者demo，感谢！ -- This is an automated message from the Apache Git Service.
