今天完成的事情

1.完成DELETE功能的实现

把DELETE变成GET

@Controller
public class StudentSController {
    @Autowired
    StudentSService studentSService;

    @RequestMapping(value="/studentS",method= RequestMethod.GET)
    public ModelAndView listStudentS(){
        System.out.println("1111111111111111");
        ModelAndView mav = new ModelAndView();
        List<StudentS> cs=studentSService.list();


        // 放入转发参数
        mav.addObject("cs", cs);
        // 放入jsp路径
        mav.setViewName("listStudentS");
        return mav;
    }


    @RequestMapping(value="/studentS",method=RequestMethod.PUT)
    public ModelAndView addStudentS(StudentS studentS){
        studentSService.add(studentS);
        ModelAndView mav=new ModelAndView("redirect:/studentS");
        return mav;
    }
    @RequestMapping(value="/StudentS/{id}",method=RequestMethod.GET)
    public ModelAndView deleteStudentS(StudentS studentS){
        studentSService.delete(studentS);
        ModelAndView mav = new ModelAndView("redirect:/studentS");
        return mav;
    }

  @RequestMapping(value="/studentS/{id}",method=RequestMethod.POST)
   public ModelAndView updateStudentS(StudentS studentS){
       studentSService.update(studentS);
       ModelAndView mav = new ModelAndView("redirect:/studentS");
       return mav;
   }
    @RequestMapping(value="/studentS/{id}",method = RequestMethod.GET)
    public ModelAndView editStudentS(StudentS studentS) {

        StudentS c = studentSService.get(studentS.getId());

        if (null == c) {
            ModelAndView mav = new ModelAndView("good");
            mav.addObject("message", "用户不存在");
            return mav;
        }



        ModelAndView mav = new ModelAndView("editStudentS");
          mav.addObject("c",c);
        return mav;


    }

这里也改成对应的GET

<tr>
    <td>id</td>
    <td>name</td>
    <td>age</td>
    <td>编辑</td>
    <td>删除</td>
</tr>
<c:forEach items="${cs}" var="c" varStatus="st">
    <tr>
        <td>${c.id}</td>
        <td>${c.name}</td>
        <td>${c.age}</td>
        <td><a href="studentS/${c.id}">编辑</a></td>
        <td><a class="GET" href="StudentS/${c.id}">删除</a></td>
        </tr>

运行

点击删除7

成功

2，学习了一下JSP的知识，就不往上复制了

明天计划的事情

学习josn

遇到的问题

无
