Form标签表单回显与提交
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
