未找到Spring Web Flow验证程序

问题描述：

我试图在Spring Web Flow中进行表单验证。为此，我使用一个验证器类，它以该模型命名。就像它在文档中所述。验证程序被实例化为一个bean，但在验证过程中从未被调用。在这个问题上的任何指针？未找到Spring Web Flow验证程序

流配置

<?xml version="1.0" encoding="UTF-8"?> 
<flow xmlns="http://www.springframework.org/schema/webflow" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation="http://www.springframework.org/schema/webflow http://www.springframework.org/schema/webflow/spring-webflow-2.4.xsd"> 

    <view-state id="createTotpKeyView" view="/templates/totp/create/create" model="key"> 
     <on-entry> 
      <evaluate expression="createTotpKeyAction"/> 
     </on-entry> 
     <transition on="submit" to="successfullyCreated" bind="true" validate="true"/> 
    </view-state> 

    <end-state id="successfullyCreated" view="/templates/totp/create/success"/> 
</flow>

这是被称为在视图状态的动作。

createTotpKeyAction

@Component 
public class CreateTotpKeyAction implements Action 
{ 
    String uid = "random"; 

    @Override 
    public Event execute(RequestContext context) throws Exception 
    { 
     try 
     { 
      // Create a TOTP key and put it in the view scope 
      TOTPKey totpKey = client.createTotpKeyForUid(uid, null); 
      context.getViewScope().put("key", totpKey); 

      return new Event(this, "success"); 
     } 
     catch (Exception e) 
     { 
      log.error("Error while creating TOTP key for user: " + uid + ".\n" + e.getMessage()); 
      // Put response message in flash scope to show it once 
      context.getFlashScope().put("fetchingError", true); 
      return new Event(this, "error"); 
     } 
    } 
}

这是我试图使用验证。编辑改名为匹配文档。

KeyValidator

@Component 
public class KeyValidator 
    { 
     [...] 

    public void validateCreateTotpKeyView(TOTPKey key, ValidationContext context) 
    { 
     System.out.println("VALIDATE VIEW STATE"); 
    } 

    public void validate(TOTPKey key, ValidationContext context) 
    { 
     System.out.println("DEFAULT VALIDATE"); 
    } 
}

我还尝试了不同的命名方案如TOTPKeyValidator或TotpKeyValidator。他们都没有工作。

唯一可行的是在TOTPKey类中创建验证方法，但我不想使用该方法。

此外，这是试图验证过程中产生的

它说Validating Model但没有任何反应的日志文件...

我建议阅读[documentation]（http://docs.spring.io/autorepo/docs/webflow/2.4.2.RELEASE/reference/html/views.html#view-validation-programmatic-validator ）。验证器的名称应该匹配以下模式'$ {model} Validator'。你的模型被命名为'key'。您的验证器应该命名为'KeyValidator'。 –

我试过了，它不起作用。 – lamemate

确保它实际上被检测到（它必须位于Spring Boot所涵盖的包中，否则它不会构造并且永远不会工作）。 –

它来到了一个错误的进口在我的验证器类中的声明。使用org.relaxng.datatype.ValidationContext代替org.springframework.binding.validation.ValidationContext将不起作用。

我之前做过这种事情，没有注意到在IDE自动完成中选择了错误的类:-) – dbreaux
