起動エラー

Wed Sep 19 14:30:49 CST 2018 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.

urlとdriverclass(Mysql公式サイト構成接続)の変更

jdbc:mysql://localhost:3306/ajia_store?characterEncoding=UTF8&serverTimezone=Asia/Shanghaiあ、真ん中の「&」に注意して、xmlではこれが読めないので、正しい書き方では「&」を「&」に変換します.
