nacos server 源码运行在本地自己创建的项目中。
正常启动的话，SpringBoot框架会自动加载resource目录下的bootstrap.yml文件中的配置，日志记录会打印相关日志：

但是我把这块的nocos代码原封不动的copy到的自己的一个项目中，修改了bootstrap.yml文件中的数据库连接。
然后启动日志打印却显示使用的是embedded storage。
日志如下：

看日志应该发现是服务没有读取到bootstrap.yml文件中的配置。应该就是定位到是bootstrap.yml没有被加载。
只要全局引入bootstrap 启动器和配置文件处理器就可以解决这个问题
<!--bootstrap 启动器-->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-bootstrap</artifactId>
</dependency>
<!--配置文件处理器-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-configuration-processor</artifactId>
<optional>true</optional>
</dependency>
<!--配置文件加解密-->
<dependency>
<groupId>com.github.ulisesbocchio</groupId>
<artifactId>jasypt-spring-boot-starter</artifactId>
<version>${jasypt.version}</version>
</dependency>也有可能是自己pom文件排除掉了相关结尾的文件，删掉过滤器就行。
<build>
<resources>
<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>
</resource>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>
</resource>
</resources>
</build>以上为个人经验，希望能给大家一个参考，也希望大家多多支持。
