无法@Autowire @Bean属性

Question

I have a DAO class which is annotated with @Configuration . In this DAO class I have a bean defined as

@Bean
public MyDao myDao(){
    return new MyDao(dataSource);
}

Now I want to use this DAO in my service class. So I annotated the service class with @Service and used

@Autowired private IMyDao myDao;

While running the tests I get the below error

org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [IMyDao] 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)}

Add this to your application context

 <context:component-scan base-package="your top level package">
    <context:include-filter type="regex"
    expression="com\.your package\..*Dao.*" />
    <context:include-filter type="regex"
    expression="com\.your package\..*Service.*" />
    <context:exclude-filter type="annotation"
    expression="org.springframework.stereotype.Controller" />
    </context:component-scan>
