Autowiring fails Not an managed Type

Question

I have a big problem in my diploma project and would be very glad if you guys could help me  I made a Maven Multi Module Project and have 3  Core-projects    NaviClean   Parent  NaviCleanDomain  contains the domain model with all my entities and an interface MeinRemoteDienst which is needed by NaviCleanServer and NaviCleanCleint for the Hessianprotocol NaviCleanClient  conatins the GUI and a Hessian connection to NaviCleanServer NaviCleanServer  Here are my repositories  my connection to the DB and the Implementation of the interface einRemoteDienst NaviCleanServer  amp  NaviCleanClient have NaviCleanDomain in Maven as Dependency    Now every time I try to start the Server on my Tomcat I get the following error    ERROR  org springframework web context ContextLoader - Context initialization failed org springframework beans factory BeanCreationException   Error creating bean with name  transaktionsRepository    Injection of persistence dependencies failed   nested exception

For me the error was quite simple based on what  alfred m said      tomcat had 2 jars conflicting having same set of Class names and configuration   What happened was               I copied my existing project to make a new project out of the existing project  but without making required changes  I started working on other project  Henec 2 projects had same classes and configuration files  resulting into conflict   Deleted the copied project and things started working

I got an very helpful advice from Oliver Gierke      The last exception you get actually indicates a problem with your JPA   setup   Not a managed bean  means not a type the JPA provider is aware   of  If you re setting up a Spring based JPA application I d recommend   to configure the  packagesToScan  property on the   LocalContainerEntityManagerFactory you have configured to the package   that contains your JPA entities  Alternatively you can list all your   entity classes in persistence xml  but that s usually more cumbersome       The former error you got  NoClassDefFound  indicates the class   mentioned is not available on the projects classpath  So you might   wanna check the inter module dependencies you have  As the two   relevant classes seem to be located in the same module it might also   just be an issue with an incomplete deployment to Tomcat  WTP is kind   of bitchy sometimes   I d definitely recommend to run a test for   verification  as you already did   As this seems to lead you to a   different exception  I guess it s really some Eclipse glitch   Thanks

When you extend indirectly JpaRepository   KassaRepository extends BaseRepository that extends JpaRepository  then you have to annotate BaseRepository with  NoRepositoryBean     NoRepositoryBean public interface BaseRepository lt T extends ModelBase gt  extends JpaRepository lt T  Long gt        T findById long id

Just in case some other poor sod ends up here because they are having the same issue I was  if you have multiple data sources and this is happening with the non-primary data source  then the problem might be with that config  The data source  entity manager factory  and transaction factory all need to be correctly configured  but also -- and this is what tripped me up -- MAKE SURE TO TIE THEM ALL TOGETHER   EnableJpaRepositories  configuration class annotation  must include entityManagerFactoryRef and transactionManagerRef to pick up all the configuration   The example in this blog finally helped me see what I was missing  which  for quick reference  were the refs here    EnableJpaRepositories      entityManagerFactoryRef    barEntityManagerFactory       transactionManagerRef    barTransactionManager       basePackages    com foobar bar     Hope this helps save someone else from the struggle I ve endured

After encountering this issue and tried different method of adding the entity packaname name to EntityScan  ComponentScan etc  none of it worked   Added the package to packageScan config in the EntityManagerFactory of the repository config  The below code gives the code based configuration as opposed to XML based ones answered above    Primary  Bean name    entityManagerFactory   public EntityManagerFactory entityManagerFactory         LocalContainerEntityManagerFactoryBean emf   new LocalContainerEntityManagerFactoryBean        emf setDataSource dataSource       emf setJpaVendorAdapter jpaVendorAdapter       emf setPackagesToScan  org package entity        emf setPersistenceUnitName  default         emf afterPropertiesSet        return emf getObject

You get the same exception when you pass the incorrect Entity object to the CrudRepository in the repository class   public interface XYZRepository extends CrudRepository lt IncorrectEntityClass  Long gt

In my case  when using IntelliJ  I had multiple modules in the project  The main module was dependent on another module which had the maven dependencies on Spring   The main module had Entitys and so did the second module  But when I ran the main module  only the Entitys from the second module got recognized as managed classes   I then added Spring dependencies on the main module as well  and guess what  It recognized all the Entitys

You should extend the scope of the component-scan e g   lt context component-scan base-package  at naviclean    gt  since you placed the entities in package at naviclean domain   This should help you to get rid the exeption   Not an managed type  class at naviclean domain Kassa   For further debugging you could try to dump the application context  see javadoc  to explore which classes have been detected by the component-scan if some are still no recognized check their annotation   Service   Component etc    EDIT   You also need to add the classes to your persistence xml    lt persistence-unit gt       lt class gt at naviclean domain Kassa lt  class gt            lt  persistence-unit gt

If anyone is strugling with the same problem I solved it by adding  EntityScan in my main class  Just add your model package to the basePackages property

Refering to Oliver Gierke s hint   When the manipulation of the persistance xml does the trick  then you created a normal java-class instead of a entity-class    When creating a new entity-class then the entry in the persistance xml should be set by Netbeans  in my case    But as mentioned by Oliver Gierke you can add the entry later to the persistance xml  if you created a normal java-class
