All Implemented Interfaces:

Closeable, AutoCloseable, Aware, BeanFactory, BeanNameAware, HierarchicalBeanFactory, InitializingBean, ListableBeanFactory, ApplicationContext, ApplicationEventPublisher, ConfigurableApplicationContext, Lifecycle, MessageSource, EnvironmentCapable, ResourceLoader, ResourcePatternResolver

Direct Known Subclasses:

ClassPathXmlApplicationContext, FileSystemXmlApplicationContext

public abstract class AbstractXmlApplicationContext
extends AbstractRefreshableConfigApplicationContext

Convenient base class for ApplicationContext implementations, drawing configuration from XML documents containing bean definitions understood by an XmlBeanDefinitionReader.

Subclasses just have to implement the getConfigResources() and/or the AbstractRefreshableConfigApplicationContext.getConfigLocations() method. Furthermore, they might override the DefaultResourceLoader.getResourceByPath(java.lang.String) hook to interpret relative paths in an environment-specific fashion, and/or AbstractApplicationContext.getResourcePatternResolver() for extended pattern resolution.

Constructor Details

AbstractXmlApplicationContext

public AbstractXmlApplicationContext()

Create a new AbstractXmlApplicationContext with no parent.

AbstractXmlApplicationContext

public AbstractXmlApplicationContext(@Nullable
 ApplicationContext parent)

Create a new AbstractXmlApplicationContext with the given parent context.

Parameters:

parent - the parent context

Method Details

setValidating

public void setValidating(boolean validating)

Set whether to use XML validation. Default is true.

loadBeanDefinitions

protected void loadBeanDefinitions(DefaultListableBeanFactory beanFactory)
                            throws BeansException,
IOException

Loads the bean definitions via an XmlBeanDefinitionReader.

Specified by:

loadBeanDefinitions in class AbstractRefreshableApplicationContext

Parameters:

beanFactory - the bean factory to load bean definitions into

Throws:

BeansException - if parsing of the bean definitions failed

IOException - if loading of bean definition files failed

See Also:

• XmlBeanDefinitionReader
• initBeanDefinitionReader(org.springframework.beans.factory.xml.XmlBeanDefinitionReader)
• loadBeanDefinitions(org.springframework.beans.factory.support.DefaultListableBeanFactory)

initBeanDefinitionReader

protected void initBeanDefinitionReader(XmlBeanDefinitionReader reader)

Initialize the bean definition reader used for loading the bean definitions of this context. The default implementation sets the validating flag.

Can be overridden in subclasses, e.g. for turning off XML validation or using a different BeanDefinitionDocumentReader implementation.

Parameters:

reader - the bean definition reader used by this context

See Also:

• XmlBeanDefinitionReader.setValidating(boolean)
• XmlBeanDefinitionReader.setDocumentReaderClass(java.lang.Class<? extends org.springframework.beans.factory.xml.BeanDefinitionDocumentReader>)

loadBeanDefinitions

protected void loadBeanDefinitions(XmlBeanDefinitionReader reader)
                            throws BeansException,
IOException

Load the bean definitions with the given XmlBeanDefinitionReader.

The lifecycle of the bean factory is handled by the AbstractRefreshableApplicationContext.refreshBeanFactory() method; hence this method is just supposed to load and/or register bean definitions.

Parameters:

reader - the XmlBeanDefinitionReader to use

Throws:

BeansException - in case of bean registration errors

IOException - if the required XML document isn't found

See Also:

• AbstractRefreshableApplicationContext.refreshBeanFactory()
• AbstractRefreshableConfigApplicationContext.getConfigLocations()
• AbstractApplicationContext.getResources(java.lang.String)
• AbstractApplicationContext.getResourcePatternResolver()

getConfigResources

@Nullable
protected Resource[] getConfigResources()

Return an array of Resource objects, referring to the XML bean definition files that this context should be built with.

The default implementation returns null. Subclasses can override this to provide pre-built Resource objects rather than location Strings.

Returns:

an array of Resource objects, or null if none
