java - Spring Data JPA (CrudRepository) - BeanCreationException: Could not autowire field -
i trying use spring data jpa - crudrepository use without implementation (all default options).
with code having exception:
exception in thread "main" org.springframework.beans.factory.beancreationexception: error creating bean name 'springjpacontactservice': injection of autowired dependencies failed; nested exception org.springframework.beans.factory.beancreationexception: not autowire field: private com.sample.hibernate.contactrepository com.sample.hibernate.repositorycontactserviceimpl.contactrepository; nested exception org.springframework.beans.factory.beancreationexception: error creating bean name 'contactrepository': invocation of init method failed; nested exception java.lang.abstractmethoderror: org.springframework.data.repository.core.support.repositoryfactorysupport.gettargetrepository(lorg/springframework/data/repository/core/repositoryinformation;)ljava/lang/object; @ org.springframework.beans.factory.annotation.autowiredannotationbeanpostprocessor.postprocesspropertyvalues(autowiredannotationbeanpostprocessor.java:334) @ org.springframework.beans.factory.support.abstractautowirecapablebeanfactory.populatebean(abstractautowirecapablebeanfactory.java:1214) @ org.springframework.beans.factory.support.abstractautowirecapablebeanfactory.docreatebean(abstractautowirecapablebeanfactory.java:543) @ org.springframework.beans.factory.support.abstractautowirecapablebeanfactory.createbean(abstractautowirecapablebeanfactory.java:482) @ org.springframework.beans.factory.support.abstractbeanfactory$1.getobject(abstractbeanfactory.java:305) @ org.springframework.beans.factory.support.defaultsingletonbeanregistry.getsingleton(defaultsingletonbeanregistry.java:230) @ org.springframework.beans.factory.support.abstractbeanfactory.dogetbean(abstractbeanfactory.java:301) @ org.springframework.beans.factory.support.abstractbeanfactory.getbean(abstractbeanfactory.java:196) @ org.springframework.beans.factory.support.defaultlistablebeanfactory.preinstantiatesingletons(defaultlistablebeanfactory.java:772) @ org.springframework.context.support.abstractapplicationcontext.finishbeanfactoryinitialization(abstractapplicationcontext.java:834) @ org.springframework.context.support.abstractapplicationcontext.refresh(abstractapplicationcontext.java:537) @ com.sample.hibernate.hibernatejpaapplication.main(hibernatejpaapplication.java:15)

everything annotations fine - no need move @repository contactrepository. because contactrepository extends crudrepository tells spring can autowire reference in repositorycontactserviceimpl. problem in maven configuration (as thinking correctly , that). changed:
<parent> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-parent</artifactid> <version>1.3.0.m2</version> <relativepath /> <!-- lookup parent repository --> </parent> to
<parent> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-parent</artifactid> <version>1.0.2.release</version> <relativepath /> <!-- lookup parent repository --> </parent> and repository works expected.
