Solución

Me encontré con un problema similar con mi proyecto Spring Hibernate en mis conjuntos de pruebas.

La única manera de resolver el problema era conectar automáticamente la clase usando su superclase como tipo (AbstractService en su caso) y luego use un @Qualifier para decirle a Spring a qué clase infantil me refiero.Se verá así en tu caso:

@Qualifier("ProductService")
@Autowired
private AbstractService productService;

Es doloroso porque luego, en la función de prueba, tienes que lanzar. productService oponerse a ProductService cada vez que utiliza un método que pertenece a la clase secundaria.Entonces, si ya resolvió esto usando otra solución, compártala con nosotros.

Otros consejos

de acuerdo con el stacktrace:

Could not autowire field: private com.example.persistence.dao.impl.ProductDao
com.example.persistence.service.impl.ProductService.dao; nested exception is 
org.springframework.beans.factory.NoSuchBeanDefinitionException:

Cuando encontré dicho problema, elimino lo siguiente:

El frijol no está anotado o no está cubierto por el análisis de componentes. Usted definió @Componentscan (BASEPACKAGES= {"com.example.persistence"})
Cubre su paquete com.example.persistence.dao.impl.productdao
Look está bien aquí.

Asegúrese de que las anotaciones sean correctas: el producto es anotado en @Repository
se ve bien.

asegúrese de que com.example.persistence.dao.impl.productdao está en la carrera. Está ejecutando el comando Prueba de gráficos limpios , lo que significa que su código se compilará antes de la ejecución de la prueba (a medida que la prueba dependa de la tarea de compilación). Si compila, supongo que el producto está en su Classpath

Asegúrese de que el JUnIT tenga la configuración requerida para el bootstrapping Contexto de la aplicación de primavera.
@ContextConfiguration
Clase apunta a su clase de configuraciones. El atributo del cargador no se definió, por lo que la primavera usará el delegante predeterminadoSmartContextExTerder (no @WebAppConfiguration en su configuración y versión> 3.2).
se ve bien conmigo.

Lamentablemente no puedo encontrar ningún problema y todo se ve bien (espero que esta lista de verificación ayude a alguien).
Así que supongo que el problema está en algún lugar en los detalles que faltan; Como si tuviera que clase de Productdao en diferentes paquetes y está utilizando el incorrecto en el servicio de productos o en la interfaz incorrecta, etc.

Espero que esto ayude
