以下是錯誤代碼：
Tue May 31 11:04:27 CST 2016 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.

解決了~！上網找了好久！如果是按老師說的URL不行，如果有出現上面的情況的。把URL改一下就行了
URL="jdbc:mysql://localhost:3306/db?useUnicode=true&characterEncoding=utf-8&useSSL=false";
有這樣的問題的這樣改就連得上了；
