Element Detail

value

@AliasFor(value="cacheNames")
public abstract String[] value

Alias for cacheNames().

Default:

{}

cacheNames

@AliasFor(value="value")
public abstract String[] cacheNames

Names of the caches to use for the cache eviction operation.

Names may be used to determine the target cache (or caches), matching the qualifier value or bean name of a specific bean definition.

Since:

4.2

value(), CacheConfig.cacheNames()

Default:

{}

key

public abstract String key

Spring Expression Language (SpEL) expression for computing the key dynamically.

Default is "", meaning all method parameters are considered as a key, unless a custom keyGenerator() has been set.

Default:

""

keyGenerator

public abstract String keyGenerator

The bean name of the custom KeyGenerator to use.

Mutually exclusive with the key() attribute.

See Also:

CacheConfig.keyGenerator()

Default:

""

cacheManager

public abstract String cacheManager

The bean name of the custom CacheManager to use to create a default CacheResolver if none is set already.

Mutually exclusive with the cacheResolver() attribute.

See Also:

SimpleCacheResolver, CacheConfig.cacheManager()

Default:

""

cacheResolver

public abstract String cacheResolver

The bean name of the custom CacheResolver to use.

See Also:

CacheConfig.cacheResolver()

Default:

""

condition

public abstract String condition

Spring Expression Language (SpEL) expression used for making the cache eviction operation conditional.

Default is "", meaning the cache eviction is always performed.

Default:

""

allEntries

public abstract boolean allEntries

Whether all the entries inside the cache(s) are removed.

By default, only the value under the associated key is removed.

Note that setting this parameter to true and specifying a key() is not allowed.

Default:

false

beforeInvocation

public abstract boolean beforeInvocation

Whether the eviction should occur before the method is invoked.

Setting this attribute to true, causes the eviction to occur irrespective of the method outcome (i.e., whether it threw an exception or not).

Defaults to false, meaning that the cache eviction operation will occur after the advised method is invoked successfully (i.e., only if the invocation did not throw an exception).

Default:

false
