单条记录
在login.html界面
<div th:each="userInfo,status:${userBean}">单条记录传递 ${list}列表记录传递
<table>
<tr><td>用户列表</td></tr>
<tr>
<td><a th:href="@{delete?(userId=${userInfo.userId})}"><span th:text="${userInfo.userId}"></span></a></td>
<td><span th:text="${userInfo.userName}"></span></td>
</tr>
</table>
</div>
2、在helloword.html界面
<form action="init" th:object="${UserBean}" method="post">
<table><tr><td>登录界面</td></tr>
<tr>
<td>用户名：<input name="UserId" type="text"/></td>
</tr>
<tr>
<td>密码:<input name="passWord" type="password"/></td>
</tr>
</table>
<button type="submit" name="dl">登 陆</button>
<button type="submit" name="zc">注 册</button>
</form>
3、init的调用方法在hellowordcontroller中写
@RequestMapping(value = "/init", method = RequestMethod.POST,params="dl")
public String initLogin(UserBean userBean, Model model) {
UserBean result = helloWorldService.searchUser(userBean);
单条记录利用userbean，列表利用list
model.addAttribute("userBean", result);
return "login"; }
@RequestMapping(value = "/init", method = RequestMethod.POST,params="zc")
public String initregister(UserBean userBean, Model model) {
UserBean result1 = helloWorldService.searchUser(userBean);
model.addAttribute("userBean", result1);
return "register";
4、在Helloworldservice中键入关键代码
public UserBean searchUser(UserBean result) {
result = queryDao.executeForObject("User.selectUser", result,UserBean.class);
return result;
}
5、在sqlmap中
<sqlMap namespace="User">
<select id="selectUser"
parameterClass="cn.training.bean.UserBean"
resultClass="cn.training.bean.UserBean">
SELECT
userid as userId,
username as userName,
password as passWord
FROM
user
where userid=#userId# and password=#passWord#
</select>
