applicationContext.xml種database配置戳錯

applicationContext.xml配置database時出現錯誤

1. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established

2. com.mchange.v2.resourcepool.BasicResourcePool$ScatteredAcquireTask@6ff9129c -- Acquisition Attempt Failed!!!

解決方法：

1. mysqlURL在高版本須要指明是否進行SSL鏈接，在MySQL鏈接字符串url中加入ssl=true或者false便可

2. URL後添加添加&serverTimezone=UTC

解決後以下所示

jdbc.url=jdbc:mysql://localhost:3306/course?characterEncoding=utf8&useSSL=true&serverTimezone=UTC
