Application. yml adds database connections, and the restart log is stuck,

Spring boot introduces JPA, and application. ymlapplication. yml adds database link parameters. The startup is stuck and logs are not dynamic, as shown in figure

After a long time, I found that the database name error occurred during the package process using Maven, as shown in figure

 

At this time, start again and find that the console Log also shows that the database name has an error.

In the Final Experiment, logs can be output normally after the compile operations that originally contain Maven, but the logs are not stuck.
