类 SimpleKeyGenerator

java.lang.Object

org.springframework.cache.interceptor.SimpleKeyGenerator

所有已实现的接口:

KeyGenerator

public class SimpleKeyGenerator
extends Object
implements KeyGenerator

Simple key generator. Returns the parameter itself if a single non-null value is given, otherwise returns a SimpleKey of the parameters.

No collisions will occur with the keys generated by this class. The returned SimpleKey object can be safely used with a ConcurrentMapCache, however, might not be suitable for all Cache implementations.

从以下版本开始:

4.0
