spring - सीतनिद्रा में होना- c3p0 हाइबरनेट मॉड्यूल क्लासलोडर द्वारा नहीं देखा जा रहा है




hibernate jboss (2)

Http://www.mkyong.com/hibernate/hibernate-could-not-find-c3p0connectionprovider/ से :

यह जगह पुरानी है, मैं पूर्व-एएस 7 कहूंगा, लेकिन साथ ही साथ लागू हो सकता है बेशक आपको एबर में शामिल हाइबरनेट के संस्करण के साथ मैच करना होगा।

सीतनिद्रा में होना v3.3 (गलत नहीं होने पर) के बाद से, "C3P0 कनेक्शन प्रदाता" एक अन्य जार फ़ाइल "हाइबरनेट-सी 3 पी 0.जर" में स्थानांतरित हो गया है। हाइबरनेट को c3p0 कनेक्शन पूल का समर्थन करने के लिए आपको इसे शामिल करना होगा।

आप "हाइबरनेट- c3p0.jar" JBoss सार्वजनिक रिपॉजिटरी से डाउनलोड कर सकते हैं।

मैं अपने वसंत / सीतनिद्रा में होना / सी 3 पी 0 / जेबीस ऐप के साथ वास्तव में एक अजीब मुद्दा रहा हूं जब यह शुरू होता है, तो लॉग से पता चलता है

मैं हाइबरनेट- c3p0-4.0.1.final.jar और c3p0-0.9.1.jar दोनों को परिनियोजन डायरेक्टरी में देख सकता हूं, वे निश्चित रूप से शामिल किए जा रहे हैं। मैंने भी हाइबरनेट खोल दिया- c3p0-4.0.1.फिनल.जर यह सुनिश्चित करने के लिए कि कक्षा वास्तव में वहां है, और यह ठीक है कि यह कहाँ होना चाहिए।

मैं डीबगर में इस के माध्यम से आगे बढ़ रहा हूं। पहली बार, क्लास को सफलतापूर्वक मॉड्यूल क्लास लोडर द्वारा तैनाती के लिए लोड किया जा रहा है। मुख्य-मुख्य-प्रूफ-अवधारणा। दूसरी बार, org.hibernate के लिए ModuleClassLoader: मुख्य कोशिश कर रहा है और उसे ढूंढने में असफल रहा है। मुझे विश्वास है कि यह कुछ प्रकार की कॉन्फ़िगरेशन समस्या है जहां हाइबरनेट मॉड्यूल क्लासलोडर यह नहीं देख सकता है कोई भी विचार मैं इसे सही दिशा में कैसे बता सकता हूं?


org.springframework.orm.hibernate4.LocalSessionFactoryBuilder.buildSessionFactory() इस संस्करण में एक बग है। यह ग़लत ढंग से मानता है कि हाइबरनेट वर्ग में पदावनत पद्धति से यह संभालता है, जो उस क्लासलोडर को लोड करता है जो उसे लोड करता है और टीसीसीएल, जो कार्यान्वयन विवरण है। इसके बजाय, यह विधि केवल उस क्लासलोडर का उपयोग करती है जो इसे लोड करती है, हायबरनेट मॉड्यूल क्लासलोडर इस क्लासलोडर के पास अपनी कक्षा के परिनियोजन वर्ग नहीं हैं, इसलिए यह ClassNotFoundException फेंक रहा है।

इस से, हम सुरक्षित रूप से कह सकते हैं कि वसंत के इस संस्करण में org.springframework.orm.hibernate4.LocalSessionFactoryBean सीतनिद्रा में होना 4 के इस संस्करण के साथ प्रयोग नहीं किया जा सकता है।
