Element Detail

commandKey

public abstract java.lang.String commandKey

Command name is used to find appropriate Hystrix command that cache should be cleared.

Returns:

command name

cacheKeyMethod

public abstract java.lang.String cacheKeyMethod

Method name to be used to get a key for request caching. The command and cache key method should be placed in the same class and have same method signature except cache key method return type, that should be String.

cacheKeyMethod has higher priority than an arguments of a method, that means what actual arguments of a method that annotated with CacheResult will not be used to generate cache key, instead specified cacheKeyMethod fully assigns to itself responsibility for cache key generation. By default this returns empty string which means "do not use cache method".

Returns:

method name or empty string

Default:

""
