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();

          • @andy I know key is template string not a instance value ,right? maybe you can use springEL to parsing the key-string.

          • 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 by pjp.getArgs() but that's hard code 。
