के लिए अनदेखा किया जा रहा मैं प्रकार MySql डेटाबेस से "सूत्री" के कॉलम को पढ़ने में सक्षम होना चाहता हूँ,AttributeConverter com.vividsolutions.jts.geom.Point
मैं उसके लिए एक AttributeConverter लिखना चाहते थे, तो मैं द्वारा शुरू किया डीबी से मूल्यों को प्रिंट करना, लेकिन मेरा एट्रिब्यूट कनवर्टर कभी नहीं कहा जाता है, इसलिए स्क्रीन पर कुछ भी मुद्रित नहीं होता है।

यह वह त्रुटि है जो मुझे मिल रही है, क्या विशेषता कनवर्टर इस त्रुटि को हल करने में मदद करनी चाहिए?

मुझे लगता है कि बिंदु GeometryUserType में परिवर्तित किया गया है। nullSafeGet विधि, लेकिन मेरे मॉडल में मान शून्य है ....
क्यों @TypeDef आंशिक रूप से काम कर रहा है और विशेषता कनवर्टर नहीं है। मुझे क्या याद आ रहा है
क्या कोई मेरी मदद कर सकता है !! धन्यवाद
क्या आप अपना pom.xml हाइबरनेट/जेपीए निर्भरताओं के साथ जोड़ सकते हैं? –
ने अभी अपना प्रश्न संपादित किया है, धन्यवाद –
कनवर्टर और कनवर्ट एनोटेशन .. पैकेज से वे हैं? –
