में झरना से अधिक ऑब्जेक्ट को हटाने के लिए, और मेरी समस्या यह है कि यह बहुत धीमी है जब मैं वस्तुओं के लिए क्वेरी और फिर हटा सकते हैं और मैं देख में दिलचस्पी है यदि कोई तेज़ तरीका है। मेरे कोड है, जो 15 Statement वस्तुओं को हटाने के लिए 15-30 के बारे में सेकंड लेता है इस तरह दिखता है:सबसे तेजी से रास्ता नहीं मैं हाइबरनेट उपयोग कर रहा हूँ एक वस्तु को दो झरना स्तर है कि नष्ट करने के लिए हाइबरनेट
public void deleteStatement(Long batchId) {
List<Statement> statements = session.createQuery("from Statement where batchId = ?").setParameter(0, batchId).list();
for(Statement statement : statements) {
session.delete(statement);
logger.debug("Deleted statement");
}
}
मैं जानता हूँ कि मैं सिर्फ कर सकता है:
session.createQuery("delete from Statement where batchId = ?").setParameter(0, batchId).executeUpdate();
लेकिन समस्या यह है कि हटाने cascades नहीं है इस विधि के साथ होता है। क्या मेरे ऑब्जेक्ट्स को मिटाने का कोई प्रभावी तरीका है और अभी भी कैस्केड होता है, या क्या मैं कुछ गलत कर रहा हूं?
सहायता के लिए धन्यवाद!
