根据javadoc，PreparedStatement继承自Statement，后者包含getResultSet（）方法。换句话说，请尝试以下操作：
String insertStatement = "INSERT INTO person(n" + " name, address, phone, customer_type, n" + " start_dtm)n" + " VALUES (?, ?, ?, ?, n" + " ?)n" + " RETURNING person_id;";PreparedStatement stmt = connection.prepareStatement(insertStatement);stmt.setObject(1, perToSave.getName(null));stmt.setObject(2, editToSave.getAddress());stmt.setObject(3, editToSave.getPhone());stmt.setObject(4, editToSave.getCustType());long epochTime = java.lang.System.currentTimeMillis();stmt.setObject(5, new java.sql.Date(epochTime));stmt.executeUpdate();ResultSet last_updated_person = stmt.getResultSet();last_updated_person.next();int last_updated_person_id = last_updated_person.getInt(1);
如果您还有其他问题，请发表评论。
