Java MySQL存放图片环境IDEAJDK 118.0.11 MySQL Community Servermysql-connector-java-8.0.21.jar导入JAR包MySQL官网下载页面实现代码MySQL类连接MySQL数据库，其中<host name>为MySQL数据库公网IP，本地则为127.0.0.1，<port>为端口号，MySQL数据库默认为3306，<user name>为用户名，<password>为密码

Java连接MySQL数据库环境IDEAJDK 11JAR包前往MySQL官网下载对应的压缩包，选择Linux或Windows版，Linux为.tar.gz格式，Windows为.zip格式下载好后，解压文件，到解压出的目录中找到*.jar文件，如mysql-connector-java-8.0.21.jar在项目主目录下创建目录lib，复制JAR包到lib/目录，导入JAR包到项目当前项目实现代码其中<host name>为MySQL数据库公网IP，本地则为127.0.

IDEA导入jar包环境IDEAJDK 11导入包选中项目目录，右键点击Open Module Setttings，或者点击快捷键F4选择Modules→\rightarrow→项目名称（如MySQL）→\rightarrow→选择jar包的路径勾选导入的包，点击Apply→\rightarrow→OK最后由于博主水平有限，不免有疏漏之处，欢迎读者随时批评指正，以免造成不必要的误解！...
