JPA API Application spring boot errors need a fix - api

Question

This is my console output.
I have been trying to find and fix my spring boot error for days and couldn't find a solution. This error is making my application not work as intended. I have included both my console output and pom.xml. Please let me know what I have to fix in order for my application to run properly.

Api Application should open instead of throwing an error.

Answer 1

I face the same issue, I don't know what exact reason for this but I think this issue happen because of the "spring-boot-starter-parent" dependency version in pom.xml.
So you can try this dependency version in pom.xml that works for me.
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.6.1</version>
<relativePath /> <!-- lookup parent from repository -->
</parent>

Answer 2

So I have the same issues using this build
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>3.0.1</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
This does not happen when version changed to
<version>2.6.1</version>
Another fix I found that worked for 3.0.1,
the imports need to be changed from
import javax.persitence.*
import jakarta.persistence.*
So I think in your model class you are using javax instead of jakarta.
Also your POM.xml is using javax
<dependency>
<groupId>javax.persistence</groupId>
<artifactId>javax.persistence-api</artifactId>
<version>2.2</version>
<scope>provided</scope>
</dependency>
