已知信息;
mysql可以远程访问
jar包等其他版本适合

修正信息：补充完整的jdbc.url

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://xxxxxxxxxxx:3306/collection?useUnicode=true&characterEncoding=utf8&useSSL=false&serverTimezone=UTC&rewriteBatchedStatements=true
jdbc.username=root
jdbc.password=jsj2018_HW03

先前url：

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://119.3.88.12:3306/collection?useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=jsj2018_HW03
