SpringMVC雖然沒有struts2那樣強大的標簽庫，但是form標簽也同樣實用
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;
//用戶狀態:0-無效,1-有效
public static String USER_STATE_VALID = "1";
public static String USER_STATE_INVALID = "0";
}
2.回顯方法
//跳轉到編輯頁面
@RequestMapping(value="/editUI")
public String editUI(String id, Model model){
boolean headImgExist = false;
if (id != null) {
User user = userService.findObjectById(id);
//回顯數據
model.addAttribute("user", user);
if (user.getHeadImg().length() > 32){
headImgExist = true;
//回顯頭像
model.addAttribute("headImg", request.getContextPath() //
+"/"+dirs+"/"+user.getHeadImg());
}
model.addAttribute("headImgExist",headImgExist);
}
return "editUI";
}
3.回顯頁面
<%@ 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>用戶管理</title>
