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).
Solution:
1 @SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
If a plurality of: modified @SpringBootApplication (exclude = {MongoAutoConfiguration.class, DataSourceAutoConfiguration.class})
2 Appeals modification does not take effect: possible reason is that idea does not specify resource directories, did not lead to the configuration file when you start reading
Methods: Right-click the resource folder -> MarkDirectory as -> Sources Root
Both methods have been tried, the second method successfully solve the problem
