解決IDEA連接MySQL數據庫 提示的SSL警告

MySQL在連接時警告

# 完整報錯信息
Fri Jan 15 14:48:07 CST 2021 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.

解決方法

Put the useSSL=false at the end of the name database

DriverManager.getConnection("JDBC:mysql:///db4?useSSL=false", "root", "root");
