JDBC连接MySQL5.7.14

１、官网下载jdbc connector 5.1.37

http://dev.mysql.com/downloads/connector/j/

２、从下载的的zip文件中取出mysql-connector-java-5.1.31-bin.jar，放到工程lib中并引用

３、参考文档例子创建连接并进行查询操作

创建连接：http://dev.mysql.com/doc/connectors/en/connector-j-usagenotes-connect-drivermanager.html#connector-j-examples-connection-drivermanager

进行查询操作：http://dev.mysql.com/doc/connectors/en/connector-j-usagenotes-statements.html#connector-j-examples-execute-select
