我有一个 SpringBoot 版本“2.3.9.RELEASE”应用程序。

Jboss 版本：jboss-eap-7.1

成功地将应用程序部署到 jboss。当我尝试通过我的 Web 应用程序登录时，出现错误。

No validator could be found for constraint 'javax.validation.constraints.NotEmpty' validating type 'java.lang.String'. Check configuration for 'emailaddress'

验证类如下

@Getter @Setter public class Login  {
@NotEmpty(message = "Please enter email address.",groups = ValidationOrder.Step1.class)
private String emailaddress;
    
@NotEmpty(message = "Please enter password.",groups = ValidationOrder.Step1.class)
private String password; }

我已将“jboss-deployment-structure”添加到“WEB-INF”目录。

<jboss-deployment-structure>
   <deployment>
      <exclusions>
         <module name="javax.validation.api" />
      </exclusions>
   </deployment>
</jboss-deployment-structure>

错误仍然存​​在。有想法吗？

它在 Netbeans 8.2 + Apache Tomcat
