MVClist显示

1、list导入的包是 java.util.list;

页面输出引用一个标签<C:foreach></c:foreach>

1、在UserSqlMap中键入关键代码：

<select id="selectUser"

parameterClass="cn.training.bean.UserBean"

resultClass="cn.training.bean.UserBean">

SELECT

userid as userId,

username as userNam

            FROM

            user      “用列表显示所有的bean语句不用条件 ”

</select>

2、在HelloWorldService中键入关键代码

public List<UserBean> searchUser(UserBean frm) {

List<UserBean> result = queryDao.executeForObjectList("User.selectUser", frm);

return result;

3、在HelloWorldController中键入关键代码：

@RequestMapping(value = "/init", method = RequestMethod.POST)

    public String initLogin(UserBean userBean, Model model) {

    List<UserBean> result = helloWorldService.searchUser(userBean);

    model.addAttribute("list", result);

        return "login";

4、在login.jsp中

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

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

${user.userId}

${user.userName}

</c:forEach>
