Annotation Interface ImportResource

@Retention(RUNTIME)
@Target(TYPE)
@Documented
public @interface ImportResource

Indicates one or more resources containing bean definitions to import.

Like @Import, this annotation provides functionality similar to the <import/> element in Spring XML configuration. It is typically used when designing @Configuration classes to be bootstrapped by an AnnotationConfigApplicationContext, but where some XML functionality such as namespaces is still necessary.

By default, arguments to the locations or value attribute will be processed using a GroovyBeanDefinitionReader for resource locations ending in ".groovy"; otherwise, an XmlBeanDefinitionReader will be used to parse Spring <beans/> XML files. Optionally, the reader() attribute may be declared, allowing the user to choose a custom BeanDefinitionReader implementation.

reader

Class<? extends BeanDefinitionReader> reader

BeanDefinitionReader implementation to use when processing resources specified via the locations or value attribute.

The configured BeanDefinitionReader type must declare a constructor that accepts a single BeanDefinitionRegistry argument.

By default, the reader will be adapted to the resource path specified: ".groovy" files will be processed with a GroovyBeanDefinitionReader; whereas, all other resources will be processed with an XmlBeanDefinitionReader.
