"IllegalArgumentException: Not a managed type" in Spring Boot application

I am using Spring Boot and JPA. It is here

I've got a domain that looks like this. Also it seems Entity annotation is deprecated so I am using @DynamicUpdate instead.

@Data
@AllArgsConstructor
@NoArgsConstructor
@DynamicUpdate
public class Person {
    private String id;
    private String name;
}

My @SpringBootApplication class looks like this

@SpringBootApplication
@ComponentScan("com.lapots.breed.platform.cloud.boot")
@EnableJpaRepositories("com.lapots.breed.platform.cloud.boot.repository")
@EntityScan("com.lapots.breed.platform.cloud.boot.domain")
public class JavaCloudSampleApplication {

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

    // executed after all beans instantiated
    @Bean
    public CommandLineRunner data(PersonRepository repository) {
        return (args) -> {
            repository.save(new Person(UUID.randomUUID().toString(), "Nike"));
        };
    }
}

The @Repository class looks like this

@Repository
public interface PersonRepository extends JpaRepository<Person, String> {
}

The @Service that uses this class looks like this

@Service
@Transactional
public class PersonService implements IPersonService {

    @Autowired
    private PersonRepository personRepository;

    @Override
    public Person findPerson(String id) {
        return personRepository.findOne(id);
    }

    @Override
    public Person generatePerson() {
        Person person = new Person();
        person.setId(UUID.randomUUID().toString());
        person.setName("Nike");
        return person;
    }
}

But when I start application I get this error:

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'personService': Unsatisfied dependency expressed through field 'personRepository'; nested exception is org.springframework.beans.factory.BeanCreationException: Error
 creating bean with name 'personRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Not a managed type: class com.lapots.breed.platform.cloud.boot.domain.Person

I'm a bit late to the game, but for anyone stumbling across this thread due to a Spring Boot v2 -> v3 migration, the real answer is to replace any javax usages with jakarta. More details here.

In Spring Boot, the base names of your repo packages must match the base names of your entity packages.

Example:
Given base name:

com.abc.mcm

Entity package name:

com.abc.mcm.entities

Repo package name:

com.abc.mcm.repositories

For those who are using Spring Data 3 and are desperately searching, I realized after a lot of research and attempts that most older advices are valid for previous versions of Spring Data but not for version 3.0.0. So all my attempts failed. I tried to:

  • add some annotations (@EnableJpaRepositories, @ComponentScan, @EntityScan) with or without the asterisk in the package name. I still got Not a managed type: class […] fatal error at the start of the program.
  • add an entityManagerFactory() bean. I got a circular reference error.

In the end, I found this official guide, which gives this sample project as example. This one uses annotations from Jakarta (ex: jakarta.persistence.Entity) instead of javax.persistence. And with Jakarta annotations my project started working.

In my case, I had a multi-maven-module project, where one of them was the model package, and others were microservices. In my case, when I ran a microservice that used a class defined in model package (domain called in my project), I had to add the @EntityScan(basePackages = {"com.example.domain"}) annotation to the @SpringBootApplication class:

@SpringBootApplication
@EnableEurekaClient
@EntityScan(basePackages = {"com.example.domain"}) // add this so the spring boot context knows where to look after entities
public class DoctorServiceApplication {

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

}

Writing up for people who will search in the future:

In your entity manager method from LocalContainerEntityManagerFactoryBean, set package which has DTO/POJO class to setPackagesToScan

Example:

@Bean
@Primary
public LocalContainerEntityManagerFactoryBean entityManagerFactory() throws Exception {
    LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
    em.setDataSource(dataSource());
    em.setPackagesToScan(new String[] {"com.abc.mainRepository.model"});
    HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
    em.setJpaVendorAdapter(vendorAdapter);
    HashMap<String, Object> properties = new HashMap<>();
    properties.put("hibernate.dialect", dialect);
    em.setJpaPropertyMap(properties);
    return em;
}

Worked for me!

(My POJO was inside the model package).

Although this question is more than 3 years old, I would like to tell the solution which has worked for me.

Put all the classes/interfaces/repositories/models etc. in the same package. This will work.

I got the same error on my Spring Boot project. I added a new package but I didn't edit componentScan.

It was like that and I got the error:

com.okan.entity

I just changed as I added:

com.okan.model.entity

You need to add @Entity in your model/POJO class as below,

@Entity
public class Person {
  //your model goes here
}

Do you have your entity mapped in your persistence.xml? Because I was with the same error and then I realized that I haven't had the entity mapped there

Maybe Person needs the Entity annotation since you are using JPA.

@Entity
@Data
@AllArgsConstructor
@NoArgsConstructor
@DynamicUpdate
public class Person {
    private String id;
    private String name;
}
