MVC删除

1、在login.jsp中键入关键代码

<c:forEach items="${list}" var="user" varStatus="status">

<table><tr>

<td><a href="delete?userId=${user.userId}">${user.userId}</td>

<td>${user.userName}</td></tr>

</table>

</c:forEach>

<c:forEach>这是个循环标签

<a href="delete?userId=${user.userId}">利用超链接实现删除

2、在HelloWordController中键入关键代码

@RequestMapping(value = "/delete", method = RequestMethod.GET)

    public String delete(UserBean userBean, Model model) {

        int result = helloWorldService.deleteUser(userBean);

    return "login";}

3、在HelloWorldService键入关键代码

public int deleteUser(UserBean frm) {

int result = updateDao.execute("User.deleteUser", frm);

                return result;}

4、在UserSqlMap中键入关键代码

<delete id="deleteUser" parameterClass="cn.training.bean.UserBean">

delete from user  WHERE userid=#userId#  

</delete>

删除语句：（delete from user  WHERE userid=#userId#  ）
