在将Spring Boot应用接入Nacos时遇到Error creating bean with name 'configurationPropertiesBeans'异常。问题根源是springboot和spring cloud版本冲突，降级至2.2.5.RELEASE解决。此外，由于httpcore依赖被标记为test scope，导致打包时缺失jar包，移除test scope后问题解决。本地IDE未报错的原因待探究。

0、增加相关依赖

注意，此处使用spring-cloud方式进行导入，需要注意两个的兼容性：

https://spring.io/projects/spring-cloud

同时需要注意spring-cloud 2020.xxx 版本后不支持bootstap文件

<!--服务发现依赖-->
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
            <version>2.2.5.RELEASE</version>
        </dependency>
<!--远程配置问题-->
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
            <version>2.2.5.RELEASE</version>
        </dependency>

1、增加一个配置文件bootstrap.yml

spring:
  profiles:
    # 默认的类型
    active: dev
  application:
    name: xxxxxxxxx-${
   spring.profiles.active}
  cloud:
    nacos:
      discovery:
        # 指定nacos的命名空间
        namespace: ${
   spring.cloud.nacos.config.namespace}
      config:
        file-extension: yaml
        # nacos地址
        server-addr: ${
   spring.cloud.nacos.server-addr}
        namespace:  ${
   spring.cloud.nacos.discovery.namespace}
        extension-configs:
          # metrics config
          - dataId: global-config.yml
            group: GLOBAL_GROUP
            refresh: true
            # email config
          - dataId: mail-config.yml
            group: GLOBAL_GROUP
            refresh: true
# ${}这种方式优先取jvm参数，其次取文件内部定义的；以spring.profiles.active为例；
# 注意name一定要和nacos上配置名一致；用这个匹配的

2、增加配置参数

-Dspring.cloud.nacos.server-addr=http://xxxxxxxxxxxxxxxx
-DlogsDir=./xxxxxxxxxxxxxxxxxxxxx
-Dspring.cloud.nacos.config.namespace=xxxxx
-Dspring.profiles.active=xxxxx

3、启动程序：

发生报错
