java.lang.Objectorg.springframework.beans.factory.support.AbstractBeanDefinitionReader
public abstract class AbstractBeanDefinitionReader
Abstract base class for bean definition readers which implement
the BeanDefinitionReader
interface.
Provides common properties like the bean factory to work on and the class loader to use for loading bean classes.

protected AbstractBeanDefinitionReader(BeanDefinitionRegistry registry)
If the passed-in bean factory does not only implement the BeanDefinitionRegistry
interface but also the ResourceLoader interface, it will be used as default
ResourceLoader as well. This will usually be the case for
ApplicationContext
implementations.
If given a plain BeanDefinitionRegistry, the default ResourceLoader will be a
PathMatchingResourcePatternResolver
.

public final BeanDefinitionRegistry getRegistry()
BeanDefinitionReader
The factory is exposed through the BeanDefinitionRegistry interface, encapsulating the methods that are relevant for bean definition handling.
getRegistry
in interface BeanDefinitionReader
public void setResourceLoader(ResourceLoader resourceLoader)
Default is PathMatchingResourcePatternResolver, also capable of resource pattern resolving through the ResourcePatternResolver interface.
Setting this to null
suggests that absolute resource loading
is not available for this bean definition reader.
ResourcePatternResolver

PathMatchingResourcePatternResolver
public ResourceLoader getResourceLoader()
BeanDefinitionReader
Null suggests that absolute resource loading is not available for this bean definition reader.
This is mainly meant to be used for importing further resources from within a bean definition resource, for example via the "import" tag in XML bean definitions. It is recommended, however, to apply such imports relative to the defining resource; only explicit full resource locations will trigger absolute resource loading.
There is also a loadBeanDefinitions(String)
method available,
for loading bean definitions from a resource location (or location pattern).
This is a convenience to avoid explicit ResourceLoader handling.
getResourceLoader
in interface BeanDefinitionReader
BeanDefinitionReader.loadBeanDefinitions(String)
,
ResourcePatternResolver
public void setBeanClassLoader(ClassLoader beanClassLoader)
Default is null
, which suggests to not load bean classes
eagerly but rather to just register bean definitions with class names,
with the corresponding Classes to be resolved later (or never).
