                pom
                import
            
        
    
    
        
            
                org.springframework.boot
                spring-boot-maven-plugin
            
        
    

1、Error creating bean with name ‘configurationPropertiesBeans‘ defined in class path resource
可能的原因是springboot和alibabacloud的版本不匹配，我遇到的是springboot版本过高，适当降低版本后解决
2、java.lang.IllegalArgumentException: Param ‘serviceName’ is illegal, serviceName is blank
配置文件没有设置服务名
#spring.application.name=服务名
3、服务要被nacos发现，这个依赖也是必须的

      
            org.springframework.boot
            spring-boot-starter-web
        

服务注册成功
