Sun Aug 27 15:43:26 CST 2023 WARN: Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.
Desde que instalé MySQL 8.0, uno de los cambios en 8.0 y 5.x es el cambio en el método de autenticación de cifrado:
- caching_sha2_password es 8.0
- mysql_native_password是5.x
solución
Cambiar la versión jdbc de mysql
Simplemente modifique el número de versión directamente en xx.pom.
Enlace de MySQL jdbc maven: http://mvnrepository.com/artifact/mysql/mysql-connector-java
Por ejemplo:
<mysql-connector.version>8.0.33</mysql-connector.version>
