Spring boot 找不到Spring Web流验证程序

我试图在SpringWebFlow中进行表单验证。为此，我使用了一个验证器类，它以模型命名。正如文档中所述。 验证器被实例化为bean，但在验证过程中从未被调用。在这个问题上有什么建议吗

流量配置

这是在视图状态下调用的操作

CreateTopKeyAction

@组件
公共类CreateTopKeyAction实现操作
{
字符串uid=“随机”；
@凌驾
公共事件执行（RequestContext上下文）引发异常
{
尝试
{
//创建TOTP键并将其放入视图范围
TOTPKey TOTPKey=client.createTotpKeyForUid（uid，null）；
context.getViewScope（）.put（“key”，totpKey）；
返回新事件（本“成功”）；
}
捕获（例外e）
{
log.error（“为用户创建TOTP密钥时出错：“+uid+”\n“+e.getMessage（））；
//将响应消息放在闪存范围内，以显示一次
context.getFlashScope（）.put（“fetchingError”，true）；
返回新事件（此“错误”）；
}
}
}

这就是我正在尝试使用的验证器编辑重命名以匹配文档

密钥验证程序

@组件
公共类密钥验证器
{
[...]
public void validateCreateTopKeyView（TOTPKey，ValidationContext上下文）
{
System.out.println（“验证视图状态”）；
}
公共void验证（TOTPKey，ValidationContext）
{
System.out.println（“默认验证”）；
}
}

我还尝试了不同的命名方案，如

TOTPKeyValidator

或

TOTPKeyValidator

。他们都没有工作

唯一有效的方法是在

TOTPKey

类中创建一个验证方法，但我不想使用这种方法

此外，这是在尝试验证期间生成的日志文件

它说

验证模型

，但什么也没发生…

这归结为我的验证器类中的一个错误的导入语句

---

使用

org.relaxng.datatype.ValidationContext

而不是

org.springframework.binding.validation.ValidationContext

将不起作用。

原因是我的验证器类中的导入语句错误

---

使用

org.relaxng.datatype.ValidationContext

而不是

org.springframework.binding.validation.ValidationContext

将不起作用。

我建议阅读。验证器的名称应与以下模式匹配

${model}验证器

。您的模型名为

key

。您的验证器应命名为

KeyValidator

。我试过了，它不起作用。请确保它确实被检测到（它必须在Spring Boot覆盖的包中，否则它不会被构造，也永远不会起作用）。它被检测为bean并被构造。我还在调试器中验证了这一点。在启动过程中调用构造函数，然后配置其他东西，bean就不可见了。但是你还没有发布这些信息。我建议你读一下。验证器的名称应与以下模式匹配
