实现对数据库的增删改查

java 9.0.4 + mysql 8.0.19 + Navicat 8 lite + eclipse 2019-12 + mysql-connector-java-8.0.19.jar

环境搭建：

[wxcaptcha]链接：https://pan.baidu.com/s/1HBIwaRJZuOc2d7ut8KpStQ
提取码：1wxk[/wxcaptcha]

安装jdk mysql Navicat

打开eclipse / window / Preferences / Server / Runtime Environments / Add

选择Apache版本9 → next 路径，jre 选择。

最后应用 Apply and Close

新建项目之后，连接数据库

直接将 mysql-connector-java-8.0.19.jar 粘贴进 WebContent 下 WEB-INF lib 下

项目开始：
