import javax.validation.constraints.NotEmpty; not found - Spring Boot

Question

Why can't I use the @NotEmpty annotation to perform validation?

This is my code:

package mx.com.gm.domain;

import java.io.Serializable;
import javax.persistence.*;
import javax.validation.constraints.Email;
import lombok.Data;

@Data
@Entity
@Table(name = "persona")
public class Persona implements Serializable{
    
    private static final long serialVersionUID = 1L;
    
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long idPersona;
    
    @NotEmpty
    private String nombre;
    
    @NotEmpty
    private String apellido;
    
    @NotEmpty
    @Email
    private String email;
    
    @NotEmpty
    private String telefono;
}

I'm trying to import javax.validation.constraints.NotEmpty, but it doesn't show up in Apache NetBeans.

I found the answer. It's because the dependency is not included in the web starter dependencies. You need to add it manually in your pom.xml file:

<dependency> 
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-validation</artifactId>
</dependency>
