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

根据引用的内容，"Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured." 是一个错误提示信息，意味着在配置数据源时没有指定'url'属性，并且没有配置嵌入式数据源。这个错误通常出现在Spring Boot项目中，在启动项目时，如果没有正确配置数据源的URL属性或者没有配置嵌入式数据源，就会抛出这个异常。具体来说，当在Spring Boot的配置文件中没有配置spring.datasource.url属性时，或者在pom.xml文件中使用了spring-boot-starter-data-jpa依赖但没有配置数据库的URL时，就会出现这个异常。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
