how can i get cacheKey when use spring cache? For example, the following code , How should this function( getCacheKey()) be implemented?
@Around("@annotation(org.springframework.cache.annotation.CachePut)")
public Object processCachePut(ProceedingJoinPoint point) throws Throwable {
Method realMethod = getRealMethod(point);
Object result = point.proceed();
String notice = null;
if (realMethod.isAnnotationPresent(CachePut.class)) {
CachePut cachePut = realMethod.getDeclaredAnnotation(CachePut.class);
String key = getCacheKey();
}
return result;
}

String key = cachePut.key() when you got a annotation from method , it's a instance contains annotation's property

thank you,but when code is written like this, it does not work. @CachePut(value = "TEST",key="'ba'+#key") public Date now(String key) { return new Date(); }

Nov 12 '18 at 12:07
@andy I know key is template string not a instance value ,right? maybe you can use springEL to parsing the key-string.
– winters
Nov 13 '18 at 2:08
thank you,key is not an instance variable.The prerequisite for building SpEL is difficult. EvaluationContext evaluationContext = createEvaluationContext(result); return evaluator.key(this.metadata.operation.getKey(),this.methodCacheKey, evaluationContext);

If you just code for specific method , you can just get method temp variables bypjp.getArgs()but that's hard code 。
