Class AnnotationCacheOperationSource

java.lang.Object
  org.springframework.cache.interceptor.AbstractFallbackCacheOperationSource
      org.springframework.cache.annotation.AnnotationCacheOperationSource

All Implemented Interfaces:

Serializable, CacheOperationSource

public class AnnotationCacheOperationSource
extends AbstractFallbackCacheOperationSource
implements Serializable

Implementation of the CacheOperationSource interface for working with caching metadata in JDK 1.5+ annotation format.

This class reads Spring's JDK 1.5+ Cacheable and CacheEvict annotations and exposes corresponding caching operation definition to Spring's cache infrastructure. This class may also serve as base class for a custom CacheOperationSource.

Constructor Summary

AnnotationCacheOperationSource()
Create a default AnnotationCacheOperationSource, supporting public methods that carry the Cacheable and CacheEvict annotations.

AnnotationCacheOperationSource(boolean publicMethodsOnly)
Create a custom AnnotationCacheOperationSource, supporting public methods that carry the Cacheable and CacheEvict annotations.

AnnotationCacheOperationSource(CacheAnnotationParser... annotationParsers)
Create a custom AnnotationCacheOperationSource.

Constructor Detail

AnnotationCacheOperationSource

public AnnotationCacheOperationSource()

Create a default AnnotationCacheOperationSource, supporting public methods that carry the Cacheable and CacheEvict annotations.

AnnotationCacheOperationSource

public AnnotationCacheOperationSource(boolean publicMethodsOnly)

Create a custom AnnotationCacheOperationSource, supporting public methods that carry the Cacheable and CacheEvict annotations.

Parameters:

publicMethodsOnly - whether to support only annotated public methods typically for use with proxy-based AOP), or protected/private methods as well (typically used with AspectJ class weaving)

AnnotationCacheOperationSource

public AnnotationCacheOperationSource(CacheAnnotationParser... annotationParsers)

Create a custom AnnotationCacheOperationSource.

Parameters:

annotationParsers - the CacheAnnotationParser to use

Method Detail

findCacheOperation

protected CacheOperation findCacheOperation(Class<?> clazz)

Description copied from class: AbstractFallbackCacheOperationSource

Subclasses need to implement this to return the caching attribute for the given class, if any.

Specified by:

findCacheOperation in class AbstractFallbackCacheOperationSource

Parameters:

clazz - the class to retrieve the attribute for

Returns:

all caching attribute associated with this class (or null if none)

findCacheOperation

protected CacheOperation findCacheOperation(Method method)

Description copied from class: AbstractFallbackCacheOperationSource

Subclasses need to implement this to return the caching attribute for the given method, if any.

Specified by:

findCacheOperation in class AbstractFallbackCacheOperationSource

Parameters:

method - the method to retrieve the attribute for

Returns:

all caching attribute associated with this method (or null if none)

determineCacheOperation

protected CacheOperation determineCacheOperation(AnnotatedElement ae)

Determine the cache operation definition for the given method or class.

This implementation delegates to configured CacheAnnotationParsers for parsing known annotations into Spring's metadata attribute class. Returns null if it's not cacheable.

Can be overridden to support custom annotations that carry caching metadata.

Parameters:

ae - the annotated method or class

Returns:

CacheOperation the configured caching operation, or null if none was found

allowPublicMethodsOnly

protected boolean allowPublicMethodsOnly()

By default, only public methods can be made cacheable.

Overrides:

allowPublicMethodsOnly in class AbstractFallbackCacheOperationSource
