मैं कैश से केवल वैध वस्तुओं को प्राप्त करने की कोशिश कर रहा हूं। अगर मैं List list = cache.getKeys(); करता हूं तो यह उन चाबियों को वापस कर देगा जो समाप्त हो चुके हैं। हालांकि मैं श्रोता जोड़ने और कुंजी को हटाने की कोशिश करता हूं, लेकिन मेरे श्रोता notifyElementExpired को कभी भी नहीं कहा जाता है।Ehcache तत्व समाप्त होने पर कुंजी को कैसे निकालें?
