第一步:导入三大框架的jar包（struts2.3.16.1+hibernate3.2+spring3.2.4）
第二步:编写web.xml 和struts.xml和applicationContext.xml和applicationContext-service.xml和application-actionContext.xml和applicationContext-dao.xml
web.xml
<?xml version="1.0" encoding="UTF-8"?>

添加一个用户
访问localhost:8080/Struts2HibernateSpring/StudentAction!add向数据库中的表添加一个用户
StudenAction省去setget方法
public class StudentAction {
private StudentService studentService;
public String add(){
System.out.println("StudentAction.add(8888888888888)");
Student student =new Student();
student.setName("shangxiaoyan");
student.setSex("女");
studentService.addStudent(student);
return null;
}
