public abstract class AbstractAutowireCapableBeanFactory extends AbstractBeanFactory implements AutowireCapableBeanFactory
RootBeanDefinition
class.
Implements the AutowireCapableBeanFactory
interface in addition to AbstractBeanFactory's createBean(java.lang.Class<T>)
method.
Provides bean creation (with constructor resolution), property population, wiring (including autowiring), and initialization. Handles runtime bean references, resolves managed collections, calls initialization methods, etc. Supports autowiring constructors, properties by name, and properties by type.
The main template method to be implemented by subclasses is
AutowireCapableBeanFactory.resolveDependency(DependencyDescriptor, String, Set, TypeConverter)
,
used for autowiring by type. In case of a factory which is capable of searching
its bean definitions, matching beans will typically be implemented through such
a search. For other factory styles, simplified matching algorithms can be implemented.
Note that this class does not assume or implement bean definition
registry capabilities. See DefaultListableBeanFactory
for an implementation
of the ListableBeanFactory
and
BeanDefinitionRegistry
interfaces, which represent the API and SPI
view of such a factory, respectively.

public void setAllowCircularReferences(boolean allowCircularReferences)
Note that circular reference resolution means that one of the involved beans will receive a reference to another bean that is not fully initialized yet. This can lead to subtle and not-so-subtle side effects on initialization; it does work fine for many scenarios, though.
Default is "true". Turn this off to throw an exception when encountering a circular reference, disallowing them completely.
NOTE: It is generally recommended to not rely on circular references between your beans. Refactor your application logic to have the two beans involved delegate to a third bean that encapsulates their common logic.
public void setAllowRawInjectionDespiteWrapping(boolean allowRawInjectionDespiteWrapping)
This will only be used as a last resort in case of a circular reference that cannot be resolved otherwise: essentially, preferring a raw instance getting injected over a failure of the entire bean wiring process.
Default is "false", as of Spring 2.0. Turn this on to allow for non-wrapped raw beans injected into some of your references, which was Spring 1.2's (arguably unclean) default behavior.
NOTE: It is generally recommended to not rely on circular references between your beans, in particular with auto-proxying involved.
setAllowCircularReferences(boolean)
public void ignoreDependencyType(Class<?> type)

- the PropertyValues to register wired objects withprotected void autowireByType(String beanName, AbstractBeanDefinition mbd, BeanWrapper bw, MutablePropertyValues pvs)
This is like PicoContainer default, in which there must be exactly one bean of the property type in the bean factory. This makes bean factories simple to configure for small namespaces, but doesn't work as well as standard Spring behavior for bigger applications.
