                org.springframework.cloud
                spring-cloud-dependencies
                2020.0.1
                pom
                import
            
            
                com.alibaba.cloud
                spring-cloud-alibaba-dependencies
                2021.1
                pom

        org.springframework.boot
        spring-boot-starter-parent

异常如下

2022-01-01 16:33:46.172 ERROR 19676 --- [           main] c.a.cloud.nacos.discovery.NacosWatch     : namingService subscribe failed, properties:NacosDiscoveryProperties{serverAddr='localhost:8848', endpoint='', namespace='', watchDelay=30000, logName='', service='', weight=1.0, clusterName='DEFAULT', group='DEFAULT_GROUP', namingLoadCacheAtStart='false', metadata={preserved.register.source=SPRING_CLOUD}, registerEnabled=true, ip='10.188.80.6', networkInterface='', port=-1, secure=false, accessKey='', secretKey='', heartBeatInterval=null, heartBeatTimeout=null, ipDeleteTimeout=null}

java.lang.IllegalArgumentException: Param 'serviceName' is illegal, serviceName is blank

配置文件 bootstrap 已经设置了 application.name,还是读取不到

解决方式

        
        
            org.springframework.cloud
            spring-cloud-starter-bootstrap
