Not Found javax.persistence in My Spring-boot Project

Here in my case, I tried to import javax.persistence, but It shows, It doesn’t exist. So I found the following solution. I hope. It will help in your case as well. The main reason for this problem is the replacement of javax with jakarta. Therefore the solution is to add the following dependency to your pom.xml.

 <dependency>
            <groupId>jakarta.persistence</groupId>
            <artifactId>jakarta.persistence-api</artifactId>
 </dependency>

Then you can import javax.persistence without any issue.

import jakarta.persistence.*;

This is the pom.xml and my java class.
