- org.springframework.cache.support.CompositeCacheManager

所有已实现的接口:
InitializingBean, CacheManager
```
public class CompositeCacheManager
extends Object
implements CacheManager, InitializingBean
```
Composite CacheManager implementation that iterates over a given collection of delegate CacheManager instances.
Allows NoOpCacheManager to be automatically added to the end of the list for handling cache declarations without a backing store. Otherwise, any custom CacheManager may play that role of the last delegate as well, lazily creating cache regions for any requested name.
Note: Regular CacheManagers that this composite manager delegates to need to return null from getCache(String) if they are unaware of the specified cache name, allowing for iteration to the next delegate in line. However, most CacheManager implementations fall back to lazy creation of named caches once requested; check out the specific configuration details for a 'static' mode with fixed cache names, if available.

`Collection<String>`	`getCacheNames()`	Get a collection of the cache names known by this manager.
`void`	`setCacheManagers(Collection<CacheManager> cacheManagers)`	Specify the CacheManagers to delegate to.
`void`	`setFallbackToNoOpCache(boolean fallbackToNoOpCache)`	Indicate whether a `NoOpCacheManager` should be added at the end of the delegate list.

  - CompositeCacheManager
```
public CompositeCacheManager()
```
    Construct an empty CompositeCacheManager, with delegate CacheManagers to be added via the "cacheManagers" property.
  - CompositeCacheManager
```
public CompositeCacheManager(CacheManager... cacheManagers)
```
    Construct a CompositeCacheManager from the given delegate CacheManagers.
    参数:
    cacheManagers - the CacheManagers to delegate to
- 方法详细资料
  - setCacheManagers
```
public void setCacheManagers(Collection<CacheManager> cacheManagers)
```
    Specify the CacheManagers to delegate to.
  - setFallbackToNoOpCache
```
public void setFallbackToNoOpCache(boolean fallbackToNoOpCache)
```
    Indicate whether a NoOpCacheManager should be added at the end of the delegate list. In this case, any getCache requests not handled by the configured CacheManagers will be automatically handled by the NoOpCacheManager (and hence never return null).
  - afterPropertiesSet
```
public void afterPropertiesSet()
```
    从接口复制的说明: InitializingBean
    Invoked by the containing BeanFactory after it has set all bean properties and satisfied BeanFactoryAware, 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
  - getCache
```
public Cache getCache(String name)
```
    从接口复制的说明: CacheManager
    Get the cache associated with the given name.
    Note that the cache may be lazily created at runtime if the native provider supports it.
    指定者:
    getCache 在接口中 CacheManager
    参数:
    name - the cache identifier (must not be null)
    返回:
    the associated cache, or null if such a cache does not exist or could be not created
  - getCacheNames
```
public Collection<String> getCacheNames()
```
    从接口复制的说明: CacheManager
    Get a collection of the cache names known by this manager.
    指定者:
    getCacheNames 在接口中 CacheManager
    返回:
    the names of all caches known by the cache manager
