I have a spring boot application and i am creating war file and deploying on Tomcat 8. The code works perfectly well when running in my Eclipse Oxygen and i am getting below exception when running application on Tomcat8.

Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'methodValidationPostProcessor' defined in class path resource [org/springframework/boot/autoconfigure/validation/ValidationAutoConfiguration.class]: Unsatisfied dependency expressed through method 'methodValidationPostProcessor' parameter 1; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'javax.validation.Validator' available: expected at least 1 bean which qualifies as autowire candidate.

public static void main(String[] args) throws Exception {

Below is my Config.java

@Configuration

    private LoggerUtil log = LoggerUtil.getInstance();

    private static final String CLASSNAME = "Config";

    @Bean(name = "validator")
    @Qualifier("validator")
    public Validator validator() {
        log.doLog(2, CLASSNAME, "validator", "inside validator = ");
        ValidatorFactory validatorFactory = Validation
                .buildDefaultValidatorFactory();
        Validator validator = validatorFactory.getValidator();
        return validator;
    }
}

Below is my AuthorizationServiceImpl.java

@Service
public class AuthorizationServiceImpl implements AuthorizationService {

    @Autowired
    @Qualifier("validator")
    private Validator validator;

    @Autowired
    @Qualifier("requestValidatorClass")
    private Map<String, String> requestValidatorClass;

    private LoggerUtil log = LoggerUtil.getInstance();

    private static final String CLASSNAME = "AuthorizationServiceImpl";

    @Override

        ResponseBean responseBean = new ResponseBean();
        final String methodName = "validate";
        String className = null;


        try {
            className = requestValidatorClass.get((type));
            log.doLog(2, CLASSNAME, methodName, "className = " + className);

            if(className != null){
                Class<?> cls = Class.forName(className);
                RequestValidator requestValidator = (RequestValidator) cls.newInstance();
                responseBean = requestValidator.validate(request, validator);
            }else{
                responseBean.setResponseCode(QRConstants.INVALID_FUNCTION);
                responseBean.setResponseMsg(Utils.getRespDesc(QRConstants.INVALID_FUNCTION));
            }
        } catch (Exception e) {
            log.doLog(3, CLASSNAME, methodName, LoggerUtil.getExStackTrace(e));
            responseBean.setResponseCode(QRConstants.TECHNICAL_ERROR_CODE);
            responseBean.setResponseMsg(Utils.getRespDesc(QRConstants.TECHNICAL_ERROR_CODE));
        }

        return responseBean;
    }

}

Can anyone let me know why i am getting this error while running my Tomcat.

Spring-boot-starter-web adds a dependency to hibernate-validator, therefor spring expects to configure a validator dependency.

Remove that dependency , add exclusion. I see you have commented the exclusion:

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

Or if you want to use this dependency, then upgrade to the latest version:

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>6.0.13.Final</version>
</dependency>
