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.

Below is my MyApp.java

    return application.sources(MyApp.class);

public static void main(String args) throws Exception {

}

Below is my Config.java

@Configuration

@EnableSwagger2

    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

        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>
