Error during startup of Spring Boot JPA app with error that entity class is not a manged type-CodePudding

First I am quite new to Springboot, learning from examples, but I am struggling with a real simple one.

I have a very minimal Springboot App with 1 Main Class, 1 repository, 1 entity. The database is PosgreSQL.

When starting the application the output contains the error message

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'cityRepository' defined in com.d043114.minimalJPA.CityRepository defined in @EnableJpaRepositories declared on JpaRepositoriesRegistrar.EnableJpaRepositoriesConfiguration: Not a managed type: class com.d043114.minimalJPA.City

The repository looks like this

package com.d043114.minimalJPA;

import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;

@Repository
public interface CityRepository extends CrudRepository<City, Long> {

}

The entity is like this:

package com.d043114.minimalJPA;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name = "cities")
public class City {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO )
    private long ID;
    
    public long getID() {
        return ID;
    }

    public void setID(long iD) {
        ID = iD;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    private String name;

}

The main class is basic as well

package com.d043114.minimalJPA;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.context.annotation.ComponentScan;


@ComponentScan(basePackages = "com.d043114.minimalJPA")
@SpringBootApplication
@EntityScan("com.d043114.minimlaJPA")
public class MinimalJpaApplication {

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

}

I played around with the @EntityScan and @ComponentScan, but am suprised that it is not working, even though repository, main class and entity are under the same package.

CodePudding user response：

Try adding this annotation as well, over 'MinimalJpaApplication' class:

@EnableJpaRepositories("my.package.base.*")
