編譯通過取不出數據是什么原因

取不出數據：

數據庫：

代碼：

我覺得是useSSL這里的問題，但是這里不論寫不寫都取不出數據，不寫的話會有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.
