Does spring webflux supports javax bean validation?

Question

I have annotated my bean with some @NotNull and use the spring @Valid annotation in the @GetMapping . But this did not work.

The only difference I see from other applications is that I use @EnableWebMvc instead of @EnableWebFlux .

In the controller:

    @PostMapping(value = "/something")
    public Mono<ResponseEntity> save(
                                @Valid @RequestBody MyBean mybean) {
        return myService.save(myBean)
                .map(RestResponses::ok)
                .defaultIfEmpty(RestResponses.empty());
    }

In the Application.java:

    @SpringBootApplication
    @EnableWebFlux
    public class Application {

        public static void main(String[] args) {
            SpringApplication.run(Application.class, args);
        }
    }

My bean class:

    import org.springframework.data.annotation.Id;
    import org.springframework.data.redis.core.RedisHash;
    import org.springframework.data.redis.core.index.Indexed;

    import javax.validation.constraints.NotNull;
    import java.util.Objects;

    @RedisHash("mybean")
    public class MyBean {

        @Id
        private Long id;

        @NotNull
        @Indexed
        private String name;

        //getters, setters...

    }

and pom.xml:

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.0.M1</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

...

 <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-webflux</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>
        <dependency>
            <groupId>io.netty</groupId>
            <artifactId>netty-all</artifactId>
        </dependency>

</dependencies>

Am I doing something wrong?

Actually there is some dependencies problem. In the dependencies you can see those two libraries:

org.hibernate:hibernate-validator:5.4.1.Final
javax.validation:validation-api:1.1.0.Final

And according to documentation Hibernate Validator you should provide additional dependency for Unified Expression Language

compile group: 'org.glassfish', name: 'javax.el', version: '3.0.1-b08'

After @Valid annotation should work as expected.
