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.
Since I installed mysql 8.0, one of the changes in 8.0 and 5.x is the change in encryption authentication method:
- caching_sha2_password is 8.0
- mysql_native_password是5.x
solution
Change the jdbc version of mysql
Just modify the version number directly in xx.pom.
Mysql jdbc maven link: http://mvnrepository.com/artifact/mysql/mysql-connector-java
For example:
<mysql-connector.version>8.0.33</mysql-connector.version>
