,InitializingBean
public class ConcurrentMapCacheFactoryBean extends Object implements FactoryBean<ConcurrentMapCache>, BeanNameAware, InitializingBean
FactoryBean
for easy configuration of aConcurrentMapCache
when used within a Spring container. Can be configured through bean properties; uses the assigned Spring bean name as the default cache name.Useful for testing or simple caching scenarios, typically in combination with
SimpleCacheManager
or dynamically throughConcurrentMapCacheManager

setName
public void setName(String name)
Specify the name of the cache.Default is "" (empty String).
setStore
public void setStore(ConcurrentMap<Object,Object> store)
Specify the ConcurrentMap to use as an internal store (possibly pre-populated).Default is a standard
ConcurrentHashMap
.
setAllowNullValues
public void setAllowNullValues(boolean allowNullValues)
Set whether to allownull
values (adapting them to an internal null holder value).Default is "true".
setBeanName
public void setBeanName(String beanName)
从接口复制的说明:BeanNameAware
Set the name of the bean in the bean factory that created this bean.Invoked after population of normal bean properties but before an init callback such as
InitializingBean.afterPropertiesSet()
or a custom init-method.- 指定者:
setBeanName
在接口中BeanNameAware
- 参数:
beanName
- the name of the bean in the factory. Note that this name is the actual bean name used in the factory, which may differ from the originally specified name: in particular for inner bean names, the actual bean name might have been made unique through appending "#..." suffixes. Use theBeanFactoryUtils.originalBeanName(String)
method to extract the original bean name (without suffix), if desired.
afterPropertiesSet
public void afterPropertiesSet()
从接口复制的说明:InitializingBean
Invoked by the containingBeanFactory
after it has set all bean properties and satisfiedBeanFactoryAware
,ApplicationContextAware
etc.This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.
- 指定者:
afterPropertiesSet
在接口中InitializingBean
getObject
public ConcurrentMapCache getObject()
从接口复制的说明:FactoryBean
Return an instance (possibly shared or independent) of the object managed by this factory.As with a
BeanFactory
, this allows support for both the Singleton and Prototype design pattern.If this FactoryBean is not fully initialized yet at the time of the call (for example because it is involved in a circular reference), throw a corresponding
FactoryBeanNotInitializedException
.As of Spring 2.0, FactoryBeans are allowed to return
null
objects. The factory will consider this as normal value to be used; it will not throw a FactoryBeanNotInitializedException in this case anymore. FactoryBean implementations are encouraged to throw FactoryBeanNotInitializedException themselves now, as appropriate.- 指定者:
getObject
在接口中FactoryBean<ConcurrentMapCache>
- 返回:
- an instance of the bean (can be
null
) - 另请参阅:
FactoryBeanNotInitializedException
getObjectType
public Class<?> getObjectType()
从接口复制的说明:FactoryBean
Return the type of object that this FactoryBean creates, ornull
if not known in advance.This allows one to check for specific types of beans without instantiating objects, for example on autowiring.
In the case of implementations that are creating a singleton object, this method should try to avoid singleton creation as far as possible; it should rather estimate the type in advance. For prototypes, returning a meaningful type here is advisable too.
This method can be called before this FactoryBean has been fully initialized. It must not rely on state created during initialization; of course, it can still use such state if available.
NOTE: Autowiring will simply ignore FactoryBeans that return
null
here. Therefore it is highly recommended to implement this method properly, using the current state of the FactoryBean.- 指定者:
getObjectType
在接口中FactoryBean<ConcurrentMapCache>
- 返回:
- the type of object that this FactoryBean creates, or
null
if not known at the time of the call - 另请参阅:
ListableBeanFactory.getBeansOfType(java.lang.Class<T>)
isSingleton
public boolean isSingleton()
从接口复制的说明:FactoryBean
Is the object managed by this factory a singleton? That is, willFactoryBean.getObject()
always return the same object (a reference that can be cached)?NOTE: If a FactoryBean indicates to hold a singleton object, the object returned from
getObject()
might get cached by the owning BeanFactory. Hence, do not returntrue
unless the FactoryBean always exposes the same reference.The singleton status of the FactoryBean itself will generally be provided by the owning BeanFactory; usually, it has to be defined as singleton there.
NOTE: This method returning
false
does not necessarily indicate that returned objects are independent instances. An implementation of the extendedSmartFactoryBean
interface may explicitly indicate independent instances through itsSmartFactoryBean.isPrototype()
method. PlainFactoryBean
implementations which do not implement this extended interface are simply assumed to always return independent instances if theisSingleton()
implementation returnsfalse
.- 指定者:
isSingleton
在接口中FactoryBean<ConcurrentMapCache>
- 返回:
- whether the exposed object is a singleton
