No qualifying bean of type available (Spring Data)

Question

I'm getting this error when I try to autowire interface that extends CrudRepository. I have two hibernate xml configs for 2 databases. The full stack is

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'helloController': Unsatisfied dependency expressed through field 'stockService'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.publishing.test.stock.services.StockService' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject(AutowiredAnnotationBeanPostProcessor.java:588) org.springframework.beans.factory.annotation.InjectionMetadata.inject(InjectionMetadata.java:88)

<hibernate-configuration>

<session-factory>

    <!-- Database connection settings -->
    <property name="connection.driver_class">org.postgresql.Driver</property>
    <property name="connection.url"></property>
    <property name="connection.username"></property>
    <property name="connection.password"></property>

    <!-- JDBC connection pool (use the built-in) -->
     <property name="connection.pool_size">100</property>

    <!-- SQL dialect -->
    <property name="dialect">org.hibernate.dialect.PostgreSQL95Dialect</property>

    <!-- Disable the second-level cache -->
    <!--<property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>-->

    <!-- Enable Hibernate's automatic session context management -->
    <property name="current_session_context_class">thread</property>

    <!-- Echo all executed SQL to stdout -->
    <property name="show_sql">true</property>

    <!-- Drop the existing table and create new one -->
    <property name="hbm2ddl.auto">update</property>

    <property name="packagesToScan">com.publishing</property>

    <!-- Mention here all the model classes -->
    <mapping class="com.publishing.models.Stock"/>

</session-factory>

@Controller
public class HelloController {


@Autowired
private StockService stockService;

I have 3 lines also in Spring Config

<context:component-scan base-package="com.publishing" />
<context:annotation-config />
<jpa:repositories base-package="com.publishing" />

Service is

@Service("StockService")
public interface StockService extends CrudRepository<Stock, Long> {

Edit:

Ok, now we have edited hibernate.cfg.xml

    <!-- Drop the existing table and create new one -->
    <property name="hbm2ddl.auto">update</property>

    <!--<property name="packagesToScan">com.publishing</property>-->

    <!-- Mention here all the model classes -->
    <mapping class="com.publishing.models.Stock"/>

And service

@Service("stockService")
public interface StockService extends CrudRepository<Stock, Long> {

This is caused by the fact that your bean/service should be named exactly the same as the instance in the controller, it's case sensitive. — cнŝdk
Can you please show the scan package configuration in your project? — cнŝdk
Now it says "Couldn't autowire There is more than one bean of StockService type" Scan package?! You mean this?! <context:component-scan base-package="com.publishing" /> — Nesquik27
Yes, that's what I meant. And that's the package where are located your services, I hope? — cнŝdk

This is caused by the fact that you defined the bean as StockService and you are referring to it as stockService, this should be the same name, case sensitive in both the service and the controller.

So the bean definition should be updated from:

@Service("StockService")

To :

@Service("stockService")

Because you are referring to it with stockService, in the controller in:

@Autowired
private StockService stockService;

Note:

Also make sure that your bean is defined in the scanned packages of spring.
