- org.springframework.cache.guava.GuavaCacheManager

All Implemented Interfaces:
CacheManager
```
public class GuavaCacheManager
extends Object
implements CacheManager
```
CacheManager implementation that lazily builds GuavaCache instances for each getCache(java.lang.String) request. Also supports a 'static' mode where the set of cache names is pre-defined through setCacheNames(java.util.Collection<java.lang.String>), with no dynamic creation of further cache regions at runtime.
The configuration of the underlying cache can be fine-tuned through a Guava CacheBuilder or CacheBuilderSpec, passed into this CacheManager through setCacheBuilder(com.google.common.cache.CacheBuilder<java.lang.Object, java.lang.Object>)/setCacheBuilderSpec(com.google.common.cache.CacheBuilderSpec). A CacheBuilderSpec-compliant expression value can also be applied via the "cacheSpecification" bean property.
Requires Google Guava 12.0 or higher.
Since:
4.0

Constructor Summary

Constructors
Constructor	Description
`GuavaCacheManager()`	Construct a dynamic GuavaCacheManager, lazily creating cache instances as they are being requested.
`GuavaCacheManager(String... cacheNames)`	Construct a static GuavaCacheManager, managing caches for the specified cache names only.

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`protected Cache`	`createGuavaCache(String name)`	Create a new GuavaCache instance for the specified cache name.
`protected com.google.common.cache.Cache<Object,Object>`	`createNativeGuavaCache(String name)`	Create a native Guava Cache instance for the specified cache name.
`Cache`	`getCache(String name)`	Get the cache associated with the given name.
`Collection<String>`	`getCacheNames()`	Get a collection of the cache names known by this manager.
`boolean`	`isAllowNullValues()`	Return whether this cache manager accepts and converts `null` values for all of its caches.
`void`	`setAllowNullValues(boolean allowNullValues)`	Specify whether to accept and convert `null` values for all caches in this cache manager.

- Constructor Detail
  - GuavaCacheManager
```
public GuavaCacheManager()
```
    Construct a dynamic GuavaCacheManager, lazily creating cache instances as they are being requested.
  - GuavaCacheManager
```
public GuavaCacheManager(String... cacheNames)
```
    Construct a static GuavaCacheManager, managing caches for the specified cache names only.
- Method Detail
  - setCacheNames
```
public void setCacheNames(Collection<String> cacheNames)
```
    Specify the set of cache names for this CacheManager's 'static' mode.
    The number of caches and their names will be fixed after a call to this method, with no creation of further cache regions at runtime.
    Calling this with a null collection argument resets the mode to 'dynamic', allowing for further creation of caches again.
  - setCacheBuilder
```
public void setCacheBuilder(com.google.common.cache.CacheBuilder<Object,Object> cacheBuilder)
```
    Set the Guava CacheBuilder to use for building each individual GuavaCache instance.
    See Also:
    createNativeGuavaCache(java.lang.String), CacheBuilder.build()
  - setCacheBuilderSpec
```
public void setCacheBuilderSpec(com.google.common.cache.CacheBuilderSpec cacheBuilderSpec)
```
    Set the Guava CacheBuilderSpec to use for building each individual GuavaCache instance.
    See Also:
    createNativeGuavaCache(java.lang.String), CacheBuilder.from(CacheBuilderSpec)
  - setCacheSpecification
```
public void setCacheSpecification(String cacheSpecification)
```
    Set the Guava cache specification String to use for building each individual GuavaCache instance. The given value needs to comply with Guava's CacheBuilderSpec (see its javadoc).
    See Also:
    createNativeGuavaCache(java.lang.String), CacheBuilder.from(String)
  - setCacheLoader
```
public void setCacheLoader(com.google.common.cache.CacheLoader<Object,Object> cacheLoader)
```
    Set the Guava CacheLoader to use for building each individual GuavaCache instance, turning it into a LoadingCache.
    See Also:
    createNativeGuavaCache(java.lang.String), CacheBuilder.build(CacheLoader), LoadingCache
  - setAllowNullValues
```
public void setAllowNullValues(boolean allowNullValues)
```
    Specify whether to accept and convert null values for all caches in this cache manager.
    Default is "true", despite Guava itself not supporting null values. An internal holder object will be used to store user-level nulls.
  - isAllowNullValues
```
public boolean isAllowNullValues()
```
    Return whether this cache manager accepts and converts null values for all of its caches.
  - getCacheNames
```
public Collection<String> getCacheNames()
```
    Description copied from interface: CacheManager
    Get a collection of the cache names known by this manager.
    Specified by:
    getCacheNames in interface CacheManager
    Returns:
    the names of all caches known by the cache manager
  - getCache
```
public Cache getCache(String name)
```
    Description copied from interface: 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.
    Specified by:
    getCache in interface CacheManager
    Parameters:
    name - the cache identifier (must not be null)
    Returns:
    the associated cache, or null if such a cache does not exist or could be not created
  - createGuavaCache
```
protected Cache createGuavaCache(String name)
```
    Create a new GuavaCache instance for the specified cache name.
    Parameters:
    name - the name of the cache
    Returns:
    the Spring GuavaCache adapter (or a decorator thereof)
  - createNativeGuavaCache
```
protected com.google.common.cache.Cache<Object,Object> createNativeGuavaCache(String name)
```
    Create a native Guava Cache instance for the specified cache name.
    Parameters:
    name - the name of the cache
    Returns:
    the native Guava Cache instance
