(Struts 2 and Spring 4 combine the development of small class information projects, which include databases, deployment environments such as Oracle11g, MyEclipse, or eclipse, use reflection mechanisms to implement and encapsulate basic BasoDao classes, use interface oriented programming thinking, and use dbpool connection pools to query independently. The goal is to combine Struts with Spring. After the deployment is successful and Tomcat is started, open the browser and enter: localH/OST: 8080/SpringTest/ClassInfo/clsManage! QueryAllClsInfo, OK, I hope it can help beginners!)
