You just need to add the dependency Validation API in the pom.xml:

<dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>
    <version>2.0.0.Final</version>
</dependency>

You just need to add spring-boot-starter-validation dependency in build.gradle file

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-validation'
}

Try this,

Step-by-step:

  1. Open "build.gradle" file. It's in your root folder project;

  2. Include the line below inside "dependencies{ }": implementation group: 'javax.validation', name: 'validation-api', version: '2.0.1.Final'

  3. Save and close build.gradle file;

  4. Next, you will see a short notification on the top of your screen to "Load Gradle Changes". Click on it.

If you don't see any notification, click on Gradle side bar, and then click on "Reload All Gradle Projects".

  1. That's all! Your annotation @Valid, @NotBlank ou @NotNull, will work.

If you get this error after attempting to import a Maven project, it may be that you need to check "Import Maven projects automatically" in the Import Project wizard. Without that the IntelliJ build may not be able to locate Maven dependencies, even if they are declared in pom.xml files.
