springcloud alibaba nacos config无法加载配置文件

直接说结论：从springboot 2.4以后，就默认不加载bootstrap配置文件了

直接就导致，无论你怎么按网上的教程去在bootstrap.properties或bootstrap.yml里面配置springcloud nacos的信息，就是无法获取配置文件

springcloud cloud alibaba使用的版本：2021.0.1.0

springboot版本：2.6.3

解决方案

方案一：直接在启动环境里面配置下

spring.cloud.bootstrap.enabled=true

方案二：添加依赖

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

• 以上方案都行
• 贴上spring官方解释

• 表现：
• 类似如下写法，在启动时，报错
