Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
2020-06-23 18:01:12.564 ERROR 22524 --- [           main] o.s.b.d.LoggingFailureAnalysisReporter   : 

***************************
APPLICATION FAILED TO START
***************************

Description:

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

Reason: Failed to determine suitable jdbc URL


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).

    the new problem can be solved as this@SpringBootApplication(exclude={DataSourceAutoConfiguration.class}),just find the xxxApplication.java and my is DemoApplication.java,add(exclude={DataSourceAutoConfiguration.class})behind@SpringBootApplication enter image description here

    Remove the spring.datasource.driver-class-name property, or rename the spring.datasource.url property to spring.datasource.jdbc-url.

    I see you are using the HikariCP library, maybe you should check the documentation for more information:

    Try this:

    spring.datasource.url=jdbc:mysql://localhost:3306/db
spring.datasource.username=
spring.datasource.password=   
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.database-platform = org.hibernate.dialect.MySQL5Dialect
spring.jpa.generate-ddl=true
spring.jpa.hibernate.ddl-auto = update

    you have another post here with the same problem, check it:
