Class CacheProxyFactoryBean

java.lang.Object

org.springframework.aop.framework.ProxyConfig

org.springframework.aop.framework.AbstractSingletonProxyFactoryBean

org.springframework.cache.interceptor.CacheProxyFactoryBean

All Implemented Interfaces:

Serializable, Aware, BeanClassLoaderAware, BeanFactoryAware, FactoryBean<Object>, InitializingBean, SmartInitializingSingleton

public class CacheProxyFactoryBean
extends AbstractSingletonProxyFactoryBean
implements BeanFactoryAware, SmartInitializingSingleton

Proxy factory bean for simplified declarative caching handling. This is a convenient alternative to a standard AOP ProxyFactoryBean with a separate CacheInterceptor definition.

This class is designed to facilitate declarative cache demarcation: namely, wrapping a singleton target object with a caching proxy, proxying all the interfaces that the target implements. Exists primarily for third-party framework integration. Users should favor the cache: XML namespace @Cacheable annotation. See the declarative annotation-based caching section of the Spring reference documentation for more information.

Method Details

setCacheOperationSources

public void setCacheOperationSources(CacheOperationSource... cacheOperationSources)

Set one or more sources to find cache operations.

See Also:

• CacheAspectSupport.setCacheOperationSources(CacheOperationSource...)

setKeyGenerator

public void setKeyGenerator(KeyGenerator keyGenerator)

Set the default KeyGenerator that this cache aspect should delegate to if no specific key generator has been set for the operation.

The default is a SimpleKeyGenerator.

Since:

5.0.3

See Also:

• CacheAspectSupport.setKeyGenerator(KeyGenerator)

setCacheResolver

public void setCacheResolver(CacheResolver cacheResolver)

Set the default CacheResolver that this cache aspect should delegate to if no specific cache resolver has been set for the operation.

The default resolver resolves the caches against their names and the default cache manager.

Since:

5.0.3

See Also:

• CacheAspectSupport.setCacheResolver(CacheResolver)

setCacheManager

public void setCacheManager(CacheManager cacheManager)

Set the CacheManager to use to create a default CacheResolver. Replace the current CacheResolver, if any.

Since:

5.0.3

See Also:

• CacheAspectSupport.setCacheManager(CacheManager)

setPointcut

public void setPointcut(Pointcut pointcut)

Set a pointcut, i.e. a bean that triggers conditional invocation of the CacheInterceptor depending on the method and attributes passed.

Note: Additional interceptors are always invoked.

• AbstractSingletonProxyFactoryBean.setPreInterceptors(Object[])
• AbstractSingletonProxyFactoryBean.setPostInterceptors(Object[])

setBeanFactory

public void setBeanFactory(BeanFactory beanFactory)

Description copied from interface: BeanFactoryAware

Callback that supplies the owning factory to a bean instance.

Invoked after the population of normal bean properties but before an initialization callback such as InitializingBean.afterPropertiesSet() or a custom init-method.

Specified by:

setBeanFactory in interface BeanFactoryAware

Parameters:

beanFactory - owning BeanFactory (never null). The bean can immediately call methods on the factory.

See Also:

• BeanInitializationException

afterSingletonsInstantiated

public void afterSingletonsInstantiated()

Description copied from interface: SmartInitializingSingleton

Invoked right at the end of the singleton pre-instantiation phase, with a guarantee that all regular singleton beans have been created already. ListableBeanFactory.getBeansOfType(Class) calls within this method won't trigger accidental side effects during bootstrap.

NOTE: This callback won't be triggered for singleton beans lazily initialized on demand after BeanFactory bootstrap, and not for any other bean scope either. Carefully use it for beans with the intended bootstrap semantics only.

Specified by:

afterSingletonsInstantiated in interface SmartInitializingSingleton

createMainInterceptor

protected Object createMainInterceptor()

Description copied from class: AbstractSingletonProxyFactoryBean

Create the "main" interceptor for this proxy factory bean. Typically an Advisor, but can also be any type of Advice.

Pre-interceptors will be applied before, post-interceptors will be applied after this interceptor.

Specified by:

createMainInterceptor in class AbstractSingletonProxyFactoryBean
