SimpleKeyGenerator (Spring Framework 4.3.30.RELEASE API)

java.lang.Object
- org.springframework.cache.interceptor.SimpleKeyGenerator

All Implemented Interfaces:
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.
Unlike DefaultKeyGenerator, 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.
Since:
4.0
