No validator could be found for constraint 'javax.validation.constraints.NotEmpty' error in JBOSS

Question

i have a SpringBoot version '2.3.9.RELEASE' application.

Jboss version: jboss-eap-7.1

successfully deployed the application to jboss. when i try to login through my web application, an error occured.

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

validation class is as below

@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; }

I have added "jboss-deployment-structure" to 'WEB-INF' directory.

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

pom.xml

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <exclusions>
        <exclusion>

</dependency>
<dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>
    <version>2.0.1.Final</version>
</dependency>

Error still remains. An idea?

Its working fine in Netbeans 8.2 + Apache Tomcat

You should use spring-boot-starter-validation instead of adding the libraries.

So remove:

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>7.0.1.Final</version>
    <type>jar</type>
</dependency>
<dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>
    <version>2.0.1.Final</version>
</dependency>

Add:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-validation</artifactId>
</dependency>

Also remove the version of lombok. This is already defined by the spring boot parent
