If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).
翻译：
Description: Failed to auto-configure a DataSource: 'spring.datasource.url'描述：未能自动配置数据源：“春天。DataSource。URL”Consider the following:考虑以下：If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.如果你想要一个嵌入式数据库（H2，HSQL或Derby），请把它放在类路径。If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).如果要从特定的配置文件中加载数据库设置，可能需要激活它（目前没有配置文件）。
解决方法：
第一种、配置数据库的数据源，
第二种、在启动类中配置
@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)或者 @EnableAutoConfiguration(exclude = DataSourceAutoConfiguration.class)
