SpringMVC虽然没有struts2那样强大的标签库，但是form标签也同样实用
1.javabean片段
public class User implements Serializable{
private static final long serialVersionUID = -1684752473484153239L;
private String id;
private String dept;
private String account;
private String name;
private String password;
private String headImg;
private Boolean gender;
private String state;
private String mobile;
private String email;
private Date birthday;
private String memo;
//用户状态:0-无效,1-有效
public static String USER_STATE_VALID = "1";
public static String USER_STATE_INVALID = "0";
}
2.回显方法
//跳转到编辑页面
@RequestMapping(value="/editUI")
public String editUI(String id, Model model){
boolean headImgExist = false;
if (id != null) {
User user = userService.findObjectById(id);
//回显数据
model.addAttribute("user", user);
if (user.getHeadImg().length() > 32){
headImgExist = true;
//回显头像
model.addAttribute("headImg", request.getContextPath() //
+"/"+dirs+"/"+user.getHeadImg());
}
model.addAttribute("headImgExist",headImgExist);
}
return "editUI";
}
3.回显页面
<%@ page contentType="text/html;charset=UTF-8" language="java" %> <%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <%@ taglib uri="http://www.springframework.org/tags/form" prefix="sf" %> <html> <head> <title>用户管理</title> <c:set var="basePath" value="${pageContext.request.contextPath}" /> <link rel="stylesheet" type="text/css" href="${basePath}/js/easyui/themes/default/easyui.css"> <link rel="stylesheet" type="text/css" href="${basePath}/js/easyui/themes/icon.css"> <script type="text/javascript" src="${basePath}/js/easyui/jquery.min.js"></script> <script type="text/javascript" src="${basePath}/js/easyui/jquery.easyui.min.js"></script> <script type="text/javascript" src="${basePath}/js/easyui/easyui-lang-zh_CN.js"> </script> <link href="${basePath}/css/skin1.css" rel="stylesheet" type="text/css" /> </head> <body class="rightBody"> <sf:form id="form" name="form" action="${basePath}/user/edit.action" method="post" modelAttribute="user" enctype="multipart/form-data"> <div class="p_d_1"> <div class="p_d_1_1"> <div class="content_info"> <div class="c_crumbs"> <div><b></b><strong>用户管理</strong> - 编辑用户</div> </div> <div class="tableH2">编辑用户</div> <table id="baseInfo" width="100%" align="center" class="list" border="0" cellpadding="0" cellspacing="0"> <tr> <td class="tdBg" width="200px">所属部门：</td> <td> <sf:select path="dept"> <sf:option value="部门A" label="部门A"/> <sf:option value="部门B" label="部门B"/> </sf:select> </td> </tr> <tr> <td class="tdBg" width="200px">头像：</td> <td> <%--判断头像是否存在，存在则显示，不存在则隐藏--%> <c:choose> <c:when test="${headImgExist}"> <img src="${headImg}" width="100" height="100"/> </c:when> <c:otherwise/> </c:choose> <input type="file" name="headImage"/> </td> </tr> <tr> <td class="tdBg" width="200px">用户名：</td> <td><sf:input path="name"/></td> </tr> <tr> <td class="tdBg" width="200px">帐号：</td> <td><sf:input path="account"/></td> </tr> <tr> <td class="tdBg" width="200px">密码：</td> <td><sf:input path="password"/></td> </tr> <tr> <td class="tdBg" width="200px">性别：</td> <td> <sf:radiobutton path="gender" value="true" label="男"/> <sf:radiobutton path="gender" value="false" label="女"/> </td> </tr> <tr> <td class="tdBg" width="200px">角色：</td> <td></td> </tr> <tr> <td class="tdBg" width="200px">电子邮箱：</td> <td><sf:input path="email"/></td> </tr> <tr> <td class="tdBg" width="200px">手机号：</td> <td><sf:input path="mobile"/></td> </tr> <tr> <td class="tdBg" width="200px">生日：</td> <td> <sf:input class="easyui-datebox" editable="false" path="birthday"/> </td> </tr> <tr> <td class="tdBg" width="200px">状态：</td> <td> <sf:radiobutton path="state" value="1" label="有效"/> <sf:radiobutton path="state" value="0" label="无效"/> </td> </tr> <tr> <td class="tdBg" width="200px">备注：</td> <td><sf:textarea path="memo"/></td> </tr> </table> <sf:hidden path="id"/> <div class="tc mt20"> <input type="submit" class="btnB2" value="保存"/> <input type="button" onclick="javascript:history.go(-1)" class="btnB2" value="返回"/> </div> </div> </div> </div> </sf:form> </body> </html>
