Class GenericAutowiredCandidateResolver

java.lang.Object

org.springframework.beans.factory.support.SimpleAutowireCandidateResolver

cz.datalite.service.GenericAutowiredCandidateResolver

All Implemented Interfaces:

org.springframework.beans.factory.Aware, org.springframework.beans.factory.config.BeanFactoryPostProcessor, org.springframework.beans.factory.support.AutowireCandidateResolver, org.springframework.context.ApplicationContextAware

public class GenericAutowiredCandidateResolver
extends org.springframework.beans.factory.support.SimpleAutowireCandidateResolver
implements org.springframework.context.ApplicationContextAware, org.springframework.beans.factory.config.BeanFactoryPostProcessor

Resolve @Autowired GenericDAO<Entity, Id> This will suggest single bean DAO matching required entity class. First all GenericDAO beans are found by type and persistenceClass property is compared to required entity class. If matched, this bean is returned. If no eligible entity is found, new bean instance is created using GenericDAOFactory.

Method Detail

getSuggestedValue

public Object getSuggestedValue(org.springframework.beans.factory.config.DependencyDescriptor descriptor)

Main method to resolve correct DAO bean. If the bean is not of type GenericDAO, default behaviour is assumed (current implementation returns null). AutowireCandidateResolver.isAutowireCandidate() should never be called for GenericDAO - all is resolved in this method and correct bean should always be returned.

Specified by:

getSuggestedValue in interface org.springframework.beans.factory.support.AutowireCandidateResolver

Overrides:

getSuggestedValue in class org.springframework.beans.factory.support.SimpleAutowireCandidateResolver

Parameters:

descriptor - descriptor of required type

Returns:

GenericDAO bean or default behaviour for other types.

createDAO

protected cz.datalite.dao.GenericDAO createDAO(org.springframework.beans.factory.config.DependencyDescriptor descriptor)

isGenericDAOOfType

protected boolean isGenericDAOOfType(cz.datalite.dao.GenericDAO dao,
                                     Type type)

setApplicationContext

public void setApplicationContext(org.springframework.context.ApplicationContext applicationContext)
                           throws org.springframework.beans.BeansException

Get application context. ListableBeanFactory is required as bean factory.

Specified by:

setApplicationContext in interface org.springframework.context.ApplicationContextAware

Parameters:

applicationContext - the context

Throws:

org.springframework.beans.BeansException

postProcessBeanFactory

public void postProcessBeanFactory(org.springframework.beans.factory.config.ConfigurableListableBeanFactory beanFactory)
                            throws org.springframework.beans.BeansException

Register this class as autowire candidate resolver.

Specified by:

postProcessBeanFactory in interface org.springframework.beans.factory.config.BeanFactoryPostProcessor

Parameters:

beanFactory - factory to use

Throws:

org.springframework.beans.BeansException
