abnormal = = = "

Quick fix = = "Add annotations on Springboot's startup class:@EnableAutoConfiguration (Exclude={datasourceautoconfiguration.class})

Principle: Springboot is a convention greater than the configuration, it will load datasource by default, if you do not add JDBC information in the configuration file, then will be an error. More details you can see other blogs, I did not read the source.

Summary: As a novice, although the solution and principle is very simple, but the harvest is to understand that Springboot is a contract greater than the configuration, after joining the starter dependency is the default load corresponding configuration. Although the Springboot project does not have so many configurations, but these configuration information is really real, you should pay attention to!
