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> {

Answer 1

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.
