org.springframework.test.context.cache.DefaultCacheAwareContextLoaderDelegate

All Implemented Interfaces:

CacheAwareContextLoaderDelegate

public class DefaultCacheAwareContextLoaderDelegate
extends java.lang.Object
implements CacheAwareContextLoaderDelegate

Default implementation of the CacheAwareContextLoaderDelegate interface.

To use a static DefaultContextCache, invoke the DefaultCacheAwareContextLoaderDelegate() constructor; otherwise, invoke the DefaultCacheAwareContextLoaderDelegate(ContextCache) and provide a custom ContextCache implementation.

Default static cache of Spring application contexts.

Constructor Detail

DefaultCacheAwareContextLoaderDelegate

public DefaultCacheAwareContextLoaderDelegate()

Construct a new DefaultCacheAwareContextLoaderDelegate using a static DefaultContextCache.

This default cache is static so that each context can be cached and reused for all subsequent tests that declare the same unique context configuration within the same JVM process.

DefaultCacheAwareContextLoaderDelegate(ContextCache)

DefaultCacheAwareContextLoaderDelegate

public DefaultCacheAwareContextLoaderDelegate(ContextCache contextCache)

Construct a new DefaultCacheAwareContextLoaderDelegate using the supplied ContextCache.

DefaultCacheAwareContextLoaderDelegate()

Method Detail

getContextCache

protected ContextCache getContextCache()

Get the ContextCache used by this context loader delegate.

loadContextInternal

protected ApplicationContext loadContextInternal(MergedContextConfiguration mergedContextConfiguration)
                                          throws java.lang.Exception

Load the ApplicationContext for the supplied merged context configuration.

Supports both the SmartContextLoader and ContextLoader SPIs.

Throws:

java.lang.Exception - if an error occurs while loading the application context

loadContext

public ApplicationContext loadContext(MergedContextConfiguration mergedContextConfiguration)

Description copied from interface: CacheAwareContextLoaderDelegate

Load the application context for the supplied MergedContextConfiguration by delegating to the ContextLoader configured in the given MergedContextConfiguration.

If the context is present in the ContextCache it will simply be returned; otherwise, it will be loaded, stored in the cache, and returned.

The cache statistics should be logged by invoking ContextCache.logStatistics().

Specified by:

loadContext in interface CacheAwareContextLoaderDelegate

Parameters:

mergedContextConfiguration - the merged context configuration to use to load the application context; never null

Returns:

the application context

closeContext

public void closeContext(MergedContextConfiguration mergedContextConfiguration,
                         DirtiesContext.HierarchyMode hierarchyMode)

Description copied from interface: CacheAwareContextLoaderDelegate

Remove the application context for the supplied MergedContextConfiguration from the ContextCache and close it if it is an instance of ConfigurableApplicationContext.

The semantics of the supplied HierarchyMode must be honored when removing the context from the cache. See the Javadoc for DirtiesContext.HierarchyMode for details.

Generally speaking, this method should only be called if the state of a singleton bean has been changed (potentially affecting future interaction with the context) or if the context needs to be prematurely removed from the cache.

Specified by:

closeContext in interface CacheAwareContextLoaderDelegate

Parameters:

mergedContextConfiguration - the merged context configuration for the application context to close; never null

hierarchyMode - the hierarchy mode; may be null if the context is not part of a hierarchy
