Class CustomAutowireConfigurer

java.lang.Object
  org.springframework.beans.factory.annotation.CustomAutowireConfigurer

All Implemented Interfaces:

BeanClassLoaderAware, BeanFactoryPostProcessor, Ordered

public class CustomAutowireConfigurer
extends Object
implements BeanFactoryPostProcessor, BeanClassLoaderAware, Ordered

A BeanFactoryPostProcessor implementation that allows for convenient registration of custom autowire qualifier types.

 <bean id="customAutowireConfigurer" class="org.springframework.beans.factory.annotation.CustomAutowireConfigurer">
   <property name="customQualifierTypes">
     <set>
       <value>mypackage.MyQualifier</value>
     </set>
   </property>
 </bean>

Method Detail

setOrder

public void setOrder(int order)

getOrder

public int getOrder()

Description copied from interface: Ordered

Return the order value of this object, with a higher value meaning greater in terms of sorting.

Normally starting with 0 or 1, with Ordered.LOWEST_PRECEDENCE indicating greatest. Same order values will result in arbitrary positions for the affected objects.

Higher value can be interpreted as lower priority, consequently the first object has highest priority (somewhat analogous to Servlet "load-on-startup" values).

Note that order values below 0 are reserved for framework purposes. Application-specified values should always be 0 or greater, with only framework components (internal or third-party) supposed to use lower values.

Specified by:

getOrder in interface Ordered

Returns:

the order value

Ordered.LOWEST_PRECEDENCE

setBeanClassLoader

public void setBeanClassLoader(ClassLoader beanClassLoader)

Description copied from interface: BeanClassLoaderAware

Callback that supplies the bean class loader to a bean instance.

Invoked after the population of normal bean properties but before an initialization callback such as InitializingBean's InitializingBean.afterPropertiesSet() method or a custom init-method.

Specified by:

setBeanClassLoader in interface BeanClassLoaderAware

Parameters:

beanClassLoader - the owning class loader; may be null in which case a default ClassLoader must be used, for example the ClassLoader obtained via ClassUtils.getDefaultClassLoader()

setCustomQualifierTypes

public void setCustomQualifierTypes(Set customQualifierTypes)

Register custom qualifier annotation types to be considered when autowiring beans. Each element of the provided set may be either a Class instance or a String representation of the fully-qualified class name of the custom annotation.

Note that any annotation that is itself annotated with Spring's Qualifier does not require explicit registration.

Parameters:

customQualifierTypes - the custom types to register

postProcessBeanFactory

public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory)
                            throws BeansException

Description copied from interface: BeanFactoryPostProcessor

Modify the application context's internal bean factory after its standard initialization. All bean definitions will have been loaded, but no beans will have been instantiated yet. This allows for overriding or adding properties even to eager-initializing beans.

Specified by:

postProcessBeanFactory in interface BeanFactoryPostProcessor

Parameters:

beanFactory - the bean factory used by the application context

Throws:

BeansException - in case of errors
