今天完成的事情：（一定要写非常细致的内容，比如说学会了盒子模型，了解了Margin）

完成了delete操作

之前出了点问题

我在listUser.jsp写如下代码

<td>
    <form action="/delete/${user.id}"  method="post"> //post 
        <input type="hidden" value="delete" name="_method"> //改行为改post为delete
        <%--<input type="submit" value="删除">--%>

        <button onClick="return fun()" >删除</button>
                <script>
                function fun(){
                    alert("删除成功")
            }
        </script>

    </form>

该为设置一个键跳转到

/delete/${user.id} // ${user.id}为取同行的id值

在controller层写以下代码

//删除
@RequestMapping(value = "/delete/{id}", method = RequestMethod.DELETE)
public ModelAndView delete(@PathVariable("id") Integer id) throws Exception{
    userService.delete(id);
    ModelAndView mav = new ModelAndView("redirect:/listUser");
    return mav;

}

@PathVariable("id")为取上面{id}的值赋予 id

ModelAndView mav = new ModelAndView("redirect:/listUser");

为跳转到/listUser

删除成功直接跳转到listUser

然后完成了add操作

<div style="text-align:center">
    <a href="http://localhost:8080/addUser">添加用户</a>
</div>

首先在listUser.jsp添加以上代码

设置一个超链接到/addUser

@RequestMapping("/addUser")
public ModelAndView add(User user) throws Exception {
    ModelAndView mav = new ModelAndView("addUser");
    return mav;
}

在controller层添加以上代码用来跳转到addUser.jsp

建立addUser.jsp

            <button type="submit" class="btn btn-default">提交</button>
        </div>
    </div>

</form>
</body>

找了一个模版来美化输入框

<form  action="/addUser/user" class="form-horizontal" role="form" method="post">

<button type="submit" class="btn btn-default">提交</button>

主要的form 又submit 进入/addUser/user 方法为post

在controller层添加

@RequestMapping(value = "/addUser/user",method = RequestMethod.POST)
public ModelAndView addd(User user) throws Exception {
    userService.add(user);
    ModelAndView mav =new ModelAndView("redirect:/listUser");
    //mav.setViewName("listUser");
    return mav;
}
