我在表单中有一个字段，它绑定到一个用户类，在表单中它的这个字段

<tr>
    <td>AcceptTerms:</td>
    <td><form:checkbox path="acceptTerms"/><td>
</tr>

但是在提交表单的那一刻出现错误

客户端发送的请求在语法上不正确。

我用萤火虫检查了它并得到了这个

Parameters   application/x-www-form-urlencoded
_acceptTerms    on
email   ZX
password    ZXZX
rol 2
username    ZxZ
Fuente
username=ZxZ&password=ZXZX&email=ZX&rol=2&_acceptTerms=on

_acceptTerms 它是复选框的隐藏值，我假设它是 spring 标记的默认值<form:checkbox>。

这给我带来了 3 个问题：这个字段 (_acceptTerms) 是否与我的表单提交混淆？为什么_acceptTerms 总是设置为开启？如果这个字段确实弄乱了我的表单，我该如何摆脱它或者我应该如何处理它？添加到用户模型？

提前致谢

  1. 如果您删除 form:checbox，您是否检查过您的表单提交是否有效，以确保该复选框确实导致了问题
  2. 你能分享服务器的调试日志吗
  3. 还分享您处理此表单提交的控制器方法，包括@requestMapping 值

您可以添加自定义活页夹以将 rol 转换为类别创建自定义属性编辑器

public class CategoryEditor extends PropertyEditorSupport {

@Override

public void setAsText(String text) {

Category cat = new Category ();

//set rol vlaue in cat

setValue(cat);

}

现在在您的控制器中使用以下方法

 @InitBinder

    public void initBinderAll(WebDataBinder binder) {

    binder.registerCustomEditor(Category .class,  new CategoryEditor ()); }
