Spring boot with H2 - Not a managed type - spring-boot

Question

I am having a problem while starting my Spring Boot application:
Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'coffeeService': Unsatisfied dependency expressed through field 'coffeeRepository': Error creating bean with name 'coffeeRepository' defined in com.coffeetime.coffeeshop.repository.CoffeeRepository defined in #EnableJpaRepositories declared on CoffeeshopApplication: Not a managed type: class com.coffeetime.coffeeshop.domain.Coffee
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'coffeeRepository' defined in com.coffeetime.coffeeshop.repository.CoffeeRepository defined in #EnableJpaRepositories declared on CoffeeshopApplication: Not a managed type: class com.coffeetime.coffeeshop.domain.Coffee
Caused by: java.lang.IllegalArgumentException: Not a managed type: class com.coffeetime.coffeeshop.domain.Coffee
The version of Spring Bot is 3.0 and Java is 17 (Most updated ones from Initialzr).
I want to use H2 as in-memory database:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>javax.persistence</groupId>
<artifactId>javax.persistence-api</artifactId>
<version>2.2</version>
</dependency>
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<scope>runtime</scope>
</dependency>
The package hierarchy is convenient to scan entities. So, I think it is not necessary to add #EntityScan (I tried it as well)
File structure
Here is application.properties:
spring.datasource.url=jdbc:h2:mem:coffeeshopdb
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.username=sa
spring.datasource.password=pass1234
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
spring.jpa.show-sql=true
spring.h2.console.enabled=true
spring.jpa.defer-datasource-initialization=true
Repository
import org.springframework.data.jpa.repository.JpaRepository;
import com.coffeetime.coffeeshop.domain.Coffee;
public interface CoffeeRepository extends JpaRepository<Coffee, Long>{
}
And the entity:
#Entity
#Table(name = "coffee")
public class Coffee {
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
private Long id;
#Column(name = "name")
#NotEmpty(message = "Coffee name cannot be empty")
private String name;
#Column(name = "amount")
#NotNull(message = "Coffee price cannot be empty")
#Min(value = 0, message = "Coffee price must be greater than or equal to 0")
private BigDecimal amount;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public BigDecimal getAmount() {
return amount;
}
public void setAmount(BigDecimal amount) {
this.amount = amount;
}
}
I checked the similar problem in this thread, no any answer worked. I suspect about H2.
Thanks
I tried using #EntityScan and playing with application.properties. But still same error.

Answer 1

I found the problem. Spring Boot 3.0.0 version started using jakarta instead of javax.persistence. Reorganizing the imports solved the problem.
