使用的 `cloud-alibaba 2021.0.1.0+ springboot2.6.8`版本

### 问题描述 ###

使用Nacos作为配置中心，然后启动报错了，而且还是报的两种错误，如下：

使用配置中心就一定要用bootstrap，我的配置如下：

server:
      port: 3377
    
    spring:
      profiles:
        active: dev
        
    spring:
      application:
        name: nacos-config-client
      cloud:
        nacos:
          discovery:
            server-addr: localhost:8848 #Nacos服务注册中心地址
          config:
            server-addr: localhost:8848 #Nacos作为配置中心地址
            file-extension: yaml #指定yaml格式的配置

配置中心也是存在这个配置文件的：

### 解决过程 ###

启动项目后我发现我的端口竟然是8080，说明bootstrap.yml配置文件压根没生效。

添加如下依赖成功解决！

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

造成这个错误的原因也有可能是`spring.application.name`没有设置。我看网上还有的人说是`discovery.service`没有设置，按理说这个不用设置，点进去会发现他默认就是取的`${spring.application.name}`

spring:
      application:
        name: nacos-config-client
      cloud:
        nacos:
          discovery:
            server-addr: localhost:8848 #Nacos服务注册中心地址
    #        service: ${spring.application.name}
