Description:

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


Action:

Consider the following:
    If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
    If you have database settings to be loaded from a particular profile you may need to activate it (the profiles dev are currently active).

bootstrap.yml

```c
spring:
  cloud:
    nacos:
      config:
        server-addr: 8.141.53.148:8848
        file-extension: yaml
        prefix: user
        group: zyj
  profiles:
    active: dev

nacos配置

pom.xml配置

```c
    <!--nacos-config-->

Failed to configure a DataSource: 'url' attribute is not specified and no embedded 的三种解决办法_人生几度秋凉-CSDN博客 在初次完成项目的构建后，启动项目时出错，提示信息“Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured. ” ，这个异常很好理解，直接翻译成中文，一看便知了 “配置数据源失败:没有指定'url'属性，也不能配置嵌入式数据源... https://blog.csdn.net/weixin_42189604/article/details/88314720

集成nacos项目本地要用bootstrap.yml ，nacos上配置的yml名称默认是你服务的名称加环境xxx-xxx-dev.yml。具体还可以指定加载环境等等。

bootstrap.yml配置写错了，profiles:active: dev，你nacos中都没有这个dev这个命名空间
