Which Component Nacos Discovery 1.4.1 dubbo Spring Cloud Alibaba 2.2.2 & 2.2.4 & 2.2.5

Describe the bug I follow the official demo, only different with more maven modules. Nacos cannot find serviceName and start failing, with setting spring.application.name. After setting spring.cloud.nacos.discovery.service, it run well.

debug info: In the NacosDiscoveryProperties.java code, the service field is incorrectly set(null). image I guess the high probability of the bug is caused by the startup sequence of Nacos.

ERROR:namingService subscribe failed java.lang.IllegalArgumentException: Param 'serviceName' is illegal, serviceName is blank

Expected behavior Nacos will automatically configure spring.cloud.nacos.discovery.service from spring.application.name

Screenshots

Additional context MacOS 、Java8 image

在spring cloud 下边 需要注意配置文件的加载顺序

bootstrap.properties > application.properties > application-dev(prod).properties

你可以把application.properties改名为bootstrap.properties再尝试一下

我的配置放在 bootstrap.properties 里会报类似的异常

我的环境是： spring-boot-starter-parent：2.4.2 spring-cloud-dependencies：2020.0.0 spring-cloud-alibaba-dependencies：2021.1

@mj19910923 你当前环境的版本,延用老版本加载方式(bootstrap.properties) 需要增加以下依赖

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-bootstrap</artifactId>
</dependency>

加上此依赖问题还是存在，复现demo链接
