后台一直在刷这一句话！


Wed Jan 30 16:40:40 CST 2019 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.

连接数据库的连接加个参数&useSSL=false，或者降低数据库版本

能说详细点嘛? 我把图片发上来了.

URL: 'mysql://localhost:3306/iconomy?useSSL=false'

然后输入 /money 后开始报错了...
