NoSuchBeanDefinitionException: No qualifying bean of type found for dependency using annotaition - spring

Question

I have such project structure:
persistence.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<persistence xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
version="2.0" xmlns="http://java.sun.com/xml/ns/persistence">
<persistence-unit name="todos" transaction-type="JTA">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>java:jboss/datasources/PostgreSQLDS</jta-data-source>
<class>server.entity.Holiday</class>
<properties>
<property name="hibernate.show_sql" value="true" />
<property name="hibernate.hbm2ddl.auto" value="update" />
</properties>
</persistence-unit>
</persistence>
Web.xml (As you can see, I'm using context Class where I will use JSON):
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
metadata-complete="false">

public InternalResourceViewResolver setupViewResolver() {
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setPrefix("/pages/");
resolver.setSuffix(".jsp");
resolver.setViewClass(JstlView.class);
return resolver;
}
}
HolidayController.class
#RestController
#RequestMapping("/holidays")
public class HolidayController {
#Autowired
private HolidayRepository holidayRepository;
#RequestMapping(value = "", method = RequestMethod.GET)
#ResponseBody
public List<Holiday> getAllHolidays() {
// List<User> list = userRepository.findAll();
return holidayRepository.findAll();
}
HolidayRepository.class:
#Repository
public interface HolidayRepository extends JpaRepository<Holiday, Long> {
}
I've got this error:
org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [server.repository.HolidayRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {#org.springframework.beans.factory.annotation.Autowired(required=true)}
Help me, please.

Answer 1

I seems you need #EnableJpaRepositories in your JavaConfig
See secton 3.2 -> http://docs.spring.io/spring-data/jpa/docs/1.9.4.RELEASE/reference/html/#repositories.definition
Create a new JavaConfig class:
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
#Configuration
#EnableJpaRepositories
class JpaSpringDataConfig {}
Or add this to your XML config:
<jpa:repositories base-package="server.repository"/>
Since your log says it expects a WebApplicationInitializer, remove your web.xml and include a class like:
public class RestWebApplicationInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
#Override
protected Class<?>[] getRootConfigClasses() {
return new Class<?>[] { JpaSpringDataConfig.class };
}
#Override
protected Class<?>[] getServletConfigClasses() {
return new Class<?>[] { WebAppConfig.class };
}
#Override
protected String[] getServletMappings() {
return new String[] { "/" };
}
}

Answer 2

Add the annotation #Repository to the implementation of HolidayRepository interface.
