Struts2如何获取JSP页面数据，action 这样写问题出在哪里，请大家指教,能否把代码修改一下，谢谢
增加学生信息
public String addStudent()throws Exception{
System.out.println("增加学生开始*******************"+studentService);
try{
Student stu = new Student();
stu.setName(name);
stu.setSex(sex);
stu.setAge(age);
stu.setBirthday(birthday);
stu.setEmail(email);
stu.setHomeAddress(homeAddress);
studentService.addStudent(stu);
//HttpServletRequest request = ServletActionContext.getRequest();
//name = request.getParameter("name");
//sex = request.getParameter("sex");
//age = Integer.parseInt(request.getParameter("age"));
//DateFormat format1 = new SimpleDateFormat("yyyy-MM-dd");
//birthday = format1.parse(request.getParameter("birthday"));
//email = request.getParameter("email");
//homeAddress = request.getParameter("homeAddress");
//Student s = new Student();
//s.setName("wangerxiao");
//s.setSex("W");
//s.setEmail("wangerxiao@163.com");
//student.setAge(20);
//student.setBirthday(new Date());
//s.setHomeAddress("响水县滨海路商业街");
//studentService.addStudent(s);
}catch(Exception ex){
ex.printStackTrace();
}
return SUCCESS;
