Answer 1

You seem to be importing the wrong dependency. If you would like to use the @Entity annotation import the following dependency:

 <dependency>
    <groupId>javax.persistence</groupId>
    <artifactId>javax.persistence-api</artifactId>
    <version>2.2</version>
 </dependency>

You can instead import the Spring data JPA package:

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

Which will allow you to use the @Entity annotation.

Also make sure to update your project when the new dependencies are added.
