can't import @Entity annotation from javax.persistence using Spring Data JPA

Question

So I'm trying to solve this problem for hours and it's really annoying. I used Spring Initializr to generate a spring boot project: java 19, spring 3.0.0, maven, with mariadb driver, spring web, spring data jpa dependencies. The problem is that after I create a model class, Student, I can't import @Entity annotation from javax.persistence. All the tutorials and videos I watched, they imported from javax.persistence but I got only jakarta.persistence. Why? I tried to add myself dependency for javax.persistency but after I create the model with all annotation (@Entity, @Table, @column) the table is not created.

Here Are my files:

Student.class

package com.example.demo;

import jakarta.persistence.Entity;
import jakarta.persistence.Id;


@Entity(name = "student") // CAN'T GET FROM JAVAX.PERSISTENCE, SAME FOR ANNOTATIONS BELOW
public class Student {
    @Id
    @Column(name="id")
    private int id;
    @Column(name="name")
    private String name;
}

application.properties locates in src/main/resources

spring.datasource.url=jdbc:mariadb://localhost:3307/db1
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=org.mariadb.jdbc.Driver
spring.jpa.hibernate.ddl-auto=create-drop

The entry point

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

}

What am I Doing wrong??

Answer 1

In the newest version of Spring Boot, javax library is replaced by jakarta (see more details here https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-3.0.0-M1-Release-Notes ) and here https://spring.io/blog/2022/01/20/spring-boot-3-0-0-m1-is-now-available , so it's ok that you can only find jakarta . You may go ahead and use it.
