All Implemented Interfaces:

InitializingBean, CacheManager

public class RedisCacheManager
extends AbstractTransactionSupportingCacheManager

CacheManager backed by a Redis cache.

This cache manager creates caches by default upon first write. Empty caches are not visible on Redis due to how Redis represents empty data structures.

Caches requiring a different RedisCacheConfiguration than the default configuration can be specified via RedisCacheManager.RedisCacheManagerBuilder.withInitialCacheConfigurations(Map).

Constructor Details

RedisCacheManager

public RedisCacheManager(RedisCacheWriter cacheWriter,
 RedisCacheConfiguration defaultCacheConfiguration)

Creates new RedisCacheManager using given RedisCacheWriter and default RedisCacheConfiguration.

Parameters:

cacheWriter - must not be null.

defaultCacheConfiguration - must not be null. Maybe just use RedisCacheConfiguration.defaultCacheConfig().

RedisCacheManager

public RedisCacheManager(RedisCacheWriter cacheWriter,
 RedisCacheConfiguration defaultCacheConfiguration,
 String... initialCacheNames)

Creates new RedisCacheManager using given RedisCacheWriter and default RedisCacheConfiguration.

Parameters:

cacheWriter - must not be null.

defaultCacheConfiguration - must not be null. Maybe just use RedisCacheConfiguration.defaultCacheConfig().

initialCacheNames - optional set of known cache names that will be created with given defaultCacheConfiguration.

RedisCacheManager

public RedisCacheManager(RedisCacheWriter cacheWriter,
 RedisCacheConfiguration defaultCacheConfiguration,
 boolean allowInFlightCacheCreation,
 String... initialCacheNames)

Creates new RedisCacheManager using given RedisCacheWriter and default RedisCacheConfiguration.

Parameters:

cacheWriter - must not be null.

defaultCacheConfiguration - must not be null. Maybe just use RedisCacheConfiguration.defaultCacheConfig().

allowInFlightCacheCreation - if set to true no new caches can be acquire at runtime but limited to the given list of initial cache names.

initialCacheNames - optional set of known cache names that will be created with given defaultCacheConfiguration.

Since:

2.0.4

RedisCacheManager

public RedisCacheManager(RedisCacheWriter cacheWriter,
 RedisCacheConfiguration defaultCacheConfiguration,
 Map<String,RedisCacheConfiguration> initialCacheConfigurations)

Creates new RedisCacheManager using given RedisCacheWriter and default RedisCacheConfiguration.

Parameters:

cacheWriter - must not be null.

defaultCacheConfiguration - must not be null. Maybe just use RedisCacheConfiguration.defaultCacheConfig().

initialCacheConfigurations - Map of known cache names along with the configuration to use for those caches. Must not be null.

RedisCacheManager

public RedisCacheManager(RedisCacheWriter cacheWriter,
 RedisCacheConfiguration defaultCacheConfiguration,
 Map<String,RedisCacheConfiguration> initialCacheConfigurations,
 boolean allowInFlightCacheCreation)

Creates new RedisCacheManager using given RedisCacheWriter and default RedisCacheConfiguration.

Parameters:

cacheWriter - must not be null.
