लेनदेन के लिए हाइबरनेट सत्र नहीं खोल सका/कनेक्शन खोल नहीं सकता

Question

मेरे आवेदन में, मेरे पास एक मॉड्यूल है जो उपयोगकर्ताओं के लिए डेटाबेस खोजने और जेएसपी के अंदर एक तालिका में अपनी जानकारी प्रदर्शित करने के लिए डिज़ाइन किया गया है। मैं बस अपने आवेदन के अंदर वसंत सुरक्षा स्थापित करें। मैं लॉगिन पेज से डेटाबेस से कनेक्शन बनाने में सक्षम था, हालांकि किसी कारण से मेरे डीएओ के सीआरयूडी ऑपरेशंस में से कोई भी नहीं (इस मामले में, खोज) काम कर रहा है।

धन्यवाद, और अगर मैं और जानकारी प्रदान कर सकता हूं तो कृपया मुझे बताएं।

यहां मेरा अधिकांश स्टैक ट्रेस है।

Answer 1

java.sql.SQLException: invalid arguments in call समस्या का मतलब है, जबकि डेटाबेस से कनेक्ट यूआरएल/प्रमाणन मुद्दों के लिए कार्य करें: देख स्टैकट्रेस अपने UserCredentialsDataSourceAdapter के माध्यम से कनेक्शन (अपने id="datasource"), लेकिन DriverManagerDataSource (id="serverDatasource") का उपयोग नहीं मिल रहा है: कुछ शब्द में अपना उपयोगकर्ता का उपयोग किए बिना कनेक्ट करने के लिए कोशिश कर रहे हैं /पारण शब्द।

sessionFactory सेम बनाने तार में:
<property name="dataSource" ref="dataSource"/>
के बजाय:
<property name="dataSource" ref="serverDatasource"/>
