spring boot Timestamp

This is my spring boot code. 

import java.security.Timestamp;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;

import org.hibernate.annotations.CreationTimestamp;
import org.hibernate.annotations.UpdateTimestamp;

import lombok.Getter;
import lombok.Setter;
import lombok.ToString;

@Getter
@Setter
@ToString
@Entity
@Table(name="tbl_board")
public class Board {
    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private Long bno;
    private String title;
    private String writer;
    private String content;

    @CreationTimestamp
    private Timestamp regdate;
    @UpdateTimestamp
    private Timestamp updatedate;
}

When I don't write Timestamp this code is free from error.

Do I need dependencies or properties in pom.xml?

But, if I use Timestamp, I can see error.

How can I solve this problem?

And this is error log.

If you are going to use UTC time, you can try LocalTime instead of Timestamp

import java.time.LocalTime;

localtime = LocalTime.now(ZoneId.of("GMT+08:00"));

Your import is wrong. As @raviiii1 suggested, instead of java.security.Timestamp use java.sql.Timestamp

@CreationTimestamp and @UpdateTimestamp can be used with the following attribute types only:

java.time.LocalDate (since Hibernate 5.2.3)
java.time.LocalDateTime (since Hibernate 5.2.3)
java.util.Date
java.util.Calendar
java.sql.Date
java.sql.Time
java.sql.Timestamp
