nacos配置中心

1、使用nacos配置中心，需要将配置文件名称改为bootstrap.yml，否则会报：

Could not resolve placeholder 'info.name' in value "${info.name}"

2、2021后的spring cloud版本需要添加spring-cloud-starter-bootstrap依赖，否则会报：

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.

Reason: Failed to determine a suitable driver class

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

3、nacos配置

spring:  
    cloud:
        nacos:
          discovery:
            server-addr: http://127.0.0.1:8848 # nacos注册地址
            group: xge
            namespace: 3ecaa9c7-8eff-4a39-995f-cc7fafe649 # 对应nacos的命名空间id
          config:
            server-addr: http://127.0.0.1:8848 # nacos注册地址
            group: xge
            namespace: 3ecaa9c7-8eff-4a39-995f-cc7fafe649 # 对应nacos的命名空间id
            prefix: project-config
            file-extension: yaml
