Class CustomAutowireConfigurer

java.lang.Object
  extended by org.springframework.beans.factory.annotation.CustomAutowireConfigurer
All Implemented Interfaces:
Aware, BeanClassLoaderAware, BeanFactoryPostProcessor, Ordered

public class CustomAutowireConfigurer
extends java.lang.Object
implements BeanFactoryPostProcessor, BeanClassLoaderAware, Ordered

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

   <property name="customQualifierTypes">
     <set>
       <value>mypackage.MyQualifier</value>

Constructor Detail

CustomAutowireConfigurer

public CustomAutowireConfigurer()
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, with Integer.MAX_VALUE indicating the greatest value. Same order values will result in arbitrary positions for the affected objects.

Higher values can be interpreted as lower priority. As a consequence, the object with the lowest value has highest priority (somewhat analogous to Servlet "load-on-startup" values).

Specified by:
getOrder in interface Ordered
Returns:
the order value

setBeanClassLoader

public void setBeanClassLoader(java.lang.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(java.util.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
