来自javax.validation.constraints的注释不起作用（忽略）

Question

I'm trying to use javax constraints to pre-validate a request content before running the logic.

I have tried any possible solution out there but still can't put javax annotations to work in a Spring boot.

import javax.validation.constraints.Min
import javax.validation.constraints.Pattern

data class LoginRequest (
        @Credential //Custom constraint that works just fine
        val credential: String,

        @Min(value= 5)
        val password: String,

        @Pattern(regexp = Constants.Regex.DEVICE_ID_REGEX, message = "Invalid device ID")
        val device: String
): Serializable

This is a part of pom.xml

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
.
.
<dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>
    <version>2.0.1.Final</version>
</dependency>
<dependency>
    <groupId>org.hibernate.validator</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>6.0.17.Final</version>
</dependency>
<dependency>
    <groupId>org.hibernate.validator</groupId>
    <artifactId>hibernate-validator-annotation-processor</artifactId>
    <version>6.0.17.Final</version>
</dependency>

And this is the controller

import javax.validation.Valid


@PostMapping("/login")
    fun userLoginEndpoint(@Valid @RequestBody loginRequest: LoginRequest): ResponseEntity<User> {
        return authService.loginUser(loginRequest)
                ?.let{ ResponseEntity(it, HttpStatus.ACCEPTED)}
                ?: ResponseEntity.status(HttpStatus.UNAUTHORIZED).build()
    }

Am I doing something wrong?

From @JBNizet comment

Replace @Min(value= 5) (and the other validation annotations too, of course) by @field:Min(value= 5) .
