在dolphinscheduler/ui页面，新建数据源时，填写好mysql数据库连接信息，测试连接时，提示错误弹窗：com.mysql.cj.jdbc.Driver，日志：ERROR] 2026-01-23 07:28:57.470 +0000 org.apache.dolphinscheduler.api.service.impl.DataSourceServiceImpl:[379] - datasource test connection error, dbType:MYSQL, connectionParam:MySQLConnectionParam{user='', password='', address='jdbc:mysql://:3306', database='spt_test', jdbcUrl='jdbc:mysql://:3306/spt_test', driverLocation='null', driverClassName='com.mysql.cj.jdbc.Driver', validationQuery='select 1', other='allowPublicKeyRetrieval=true&serverTimezone=Asia/Shanghai&characterEncoding=utf8&useSSL=false&'}, message:com.mysql.cj.jdbc.Driver.
