@Entity
@Table(name = "users", uniqueConstraints = { @UniqueConstraint(columnNames = { "email" }) })
public class User {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private Long userId;
@Column(nullable = false, length = 30)

@NotEmpty(message = "Email cannot be empty")

I'm trying to use the spring Email core package in my spring boot project. I have added the dependency in my pom file but for some weird reason the import statement for import javax.validation.constraints.Email; is not getting resolved. Any idea why is this happening?? Here is the dependency , i have ...

javax.validation.constraints.Email annotation depends on Jakarta Bean Validation providers for validation.

You could try to add spring-boot-starter-validation dependency to your pom.xml. This dependency contains all the required dependencies (including jakarta and hibernate-validator which is a compliant validator for this)

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