Chinese garbled characters appear when the spring boot project in IDEA reads the properties file
Solution
IDEA has advanced advantages, and there is the option of Transparent native-to-ascii conversion, which
is to convert utf-8 file encoding to ASCII encoding
If after following the above settings, restart the service, restart IDEA, the access is still garbled
, delete the previously created properties file and recreate it
Another solution is to change the application.properties configuration file to application.yaml file
