写一个jsp页面

<%@ page contentType="text/html;charset=UTF-8" language="java" %>            <%--name = oyb & sex = male = {
    "name":"oyb","sex":"male"}--%>
     
          用户名:
      
      
    性别:
      
      
    
      
     

写一个StudentController

package oyb.Controller;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestBody;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;import oyb.model.Student;@Controller@RequestMapping("/stu")public class StudentController {    @RequestMapping("/toReg")    public  String toReg(  Student stu){        System.out.println(stu);        return "stu/register";    }    @RequestMapping("/save")    /**     * @RequestBody:把json数据转成模型对象     *@ResponseBody 返回json数据，把对象转成json字符串返回客户端     */    public  @ResponseBody    Student save(@RequestBody Student stu){        System.out.println(stu);        return stu;    }}
