oop - Hibernate SessionFactory -

क्यों हाइबरनेट के उदाहरणों को सत्रफ़ायर इंटरफ़ेस के बजाय SessionFactoryImpl वर्ग का उपयोग करें दिए गए कनेक्शन पर एक सत्र खोलें?

क्या कार्यान्वयन बदल सकता है? सामान्य तौर पर, यदि आप किसी ऑब्जेक्ट के साथ इंटरैक्ट करने के लिए इंटरफ़ेस का उपयोग कर सकते हैं, तो आपको चाहिए इंटरफेस कक्षाओं की तुलना में कम होने की संभावना है, इसलिए यदि कोई इंटरफ़ेस के अनुरूप हो, तो इंटरफ़ेस से हमेशा इसका संदर्भ दें। यह बहुत ही मानक ओओपी अभ्यास है।
