If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.

Description:
 
Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.
//無法配置數據庫，沒有指定url屬性，並且無法配置embedded datasource
Reason: Failed to determine a suitable driver class
//原因：無法明確指定正確的驅動類（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 (no profiles are currently active).
 
//建議：
//如果如果需要加載嵌入式的數據庫，請將他放入路徑中
//如果有數據庫設置需要從指定配置文件中加載，需要調用該配置文件（目前沒有活動的配置文件）

按照上述的解決辦法:)

程序入口處:
 
@SpringBootApplication
public class DemoApplication {
 
修改為:
@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
public class DemoApplication {
}
