Introducing Spring Framework

Chapter 4 ■ Using Beans Scopes
@Bean
public Type webType(){
return getTypeFromMap("web");
}
@Bean
@Scope("prototype")
public SearchEngine engine(){
ServiceSearchEngine engine = new ServiceSearchEngine();
engine.setDocumentDAO(documentDAO());
if(log.isDebugEnabled())
log.debug("SearchEngine created: " + engine);
}
return engine;
public MyDocumentsContext(){
}
//...Omitted calls
//... Omitted methods
}
Running the unit test, you should get the same results. You can find each of these tests in Chapter 4 of the book’s
companion source code.
Using Bean Scopes in the New GroovyBeanDefinitionReader
Context
Using the new Groovy integration will be as easy as setting the word scope in the mydocuments.groovy file
(see Listing 4-6).
Listing 4-6. mydocuments.groovy
import com.apress.isf.spring.service.ServiceSearchEngine
import com.apress.isf.spring.data.DocumentRepository
import com.apress.isf.java.model.Document
beans {
engine(SearchEngineService){ bean ->
bean.scope = "prototype"
documentDAO = ref("documentDAO")
}
