Cannot determine embedded database driver class for database type NONE

SpringBoot may report the following errors during startup:

     Cannot determine embedded database driver class for database type NONE

 

Solution:

           This is because spring boot will be loaded by default

       

org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration this class

 

The DataSourceAutoConfiguration class uses the @Configuration annotation to inject the dataSource bean into spring. Because there is no configuration information related to dataSource in the project, when spring creates a dataSource bean, an error will be reported due to the lack of relevant information.

The solution is to:

Add on Application class

 

@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
