Jsp + tomcat + mysql & amp; sevlet & amp; javabean configuration process

Many problems may occur when configuring the jsp development environment. Thanks to the experiences of many predecessors on the internet, the author cl41's JSP connection to the Mysql database strategy and the author's Saulzy's MySQL study notes and other articles are just for me to send carbon in the snow. In order to help beginners like me, I have summarized many of my experiences here, I am very grateful for their selfless dedication and hope that more people will carry forward this spirit!
