Reason:

This is because spring boot will load the Org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration class by default,

The Datasourceautoconfiguration class uses the @configuration annotation to inject datasource beans into spring. Because there is no configuration information related to datasource in the project, the spring creation DataSource Bean will be error-free due to lack of relevant information. Solutions

@EnableAutoConfiguration (Exclude={datasourceautoconfiguration.class})
