JDBC連接MySQL5.7.14

１、官網下載jdbc connector 5.1.37

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

２、從下載的的zip文件中取出mysql-connector-java-5.1.31-bin.jar，放到工程lib中並引用

３、參考文檔例子創建連接並進行查詢操作

創建連接：http://dev.mysql.com/doc/connectors/en/connector-j-usagenotes-connect-drivermanager.html#connector-j-examples-connection-drivermanager

進行查詢操作：http://dev.mysql.com/doc/connectors/en/connector-j-usagenotes-statements.html#connector-j-examples-execute-select
