nested exception is java.lang.IllegalArgumentException: Not a managed type: class
Solution 1
Spring is not aware of your entity. You need to denote MySpringBootApplication
class with @EntityScan("your.entities.package")
Solution 2
In my case it was missing @Entity
& and @Id
annotation in Entity class.
Solution 3
You should put Entity class same module with Repository class, If not , you should add @EntityScan to your application class

I am trying to deploy a
Spring-Boot application
withService
accessing aJpaRepository
which is connecting toPostgreSQL DB
at runtime usingJPA
andHibernate
, refering to connection properties insrc/main/resources/application.properties
When I am deploying the built .WAR on Tomcat, the Application is failing to start with the error as given in below Error Log.
Can somebody please help out what is the meaning of this error?
Note I have noted the trouble points in
MyServiceImpl
andMyRequestBody
classes but I am not getting the exact reason for the error, as I am new to Spring framework.The definitions of the relevant classes in my Spring Boot Starter project are as follows:
Spring Boot Application
@SpringBootApplication @ComponentScan(<root package name under which all subpackages containing relevant classes >) public class MySpringBootApplication extends SpringBootServletInitializer {
My Spring-Boot RestController class (autowiring the MyService class instance )
@RestController public class MyController { @Autowired MyService myService;
My Service interface (I have not provided any @Service annotation)
public interface MyService { //all service method definitions }
Spring ServiceImpl class with the autowiring repository instance to operate on PostgreSQL DB
@Service("myService") public class MyServiceImpl implements MyService { @Autowired private MyRepository myRepository; <-- **ERROR -- Bean not found** //other default services e.g. find, add, delete, update, etc. }
My Repository class
@Repository public interface MyRepository extends JpaRepository<MyRequestBody, Long> { @Query("select h from MyRequestBody h where h.column1 = ?1") List<MyRequestBody> findByColumn1(String col1); }
My Entity class
@Entity @Table(name = "myTable", schema = "my_db") public class MyRequestBody { <-- **ERROR -- Not a managed class type** @Id @Column(name = "id") @GeneratedValue(strategy = GenerationType.SEQUENCE) private Long id; @Column(name = "column1") private String column1; //getter and setter AND toString methods

somnathchakrabarti over 6 yearsGetting a new error after entering @EntityScan to MySpringBootApplication class. Edited my question with the new Error Log
-
somnathchakrabarti over 6 yearsDo I need to add
@EnableJpaRepositories("package_for_repository")
toMySpringBootApplication
class? -
somnathchakrabarti over 6 yearsYes after adding
@EnableJpaRepositories
, it worked! -
old_soul_on_the_run about 5 yearsEntityScan is a new annotation I learned and it worked for me. I am just wondering why Spring did not mention about it. I was understand the impression that even the entity classes will be scanned by scanBasePackage. Anyways Thanks!

Woodsman about 3 yearsI have a similar error, however, I added an EnableJpaRepositories and an EntityScan annotation on the Application and specified the exact package. The entity has an Entity and Id annotation, despite all this it still does not care.
