LLaVA-1.5：多模态视觉问答新突破 LLaVA-1.5在多模态视觉问答（VQA）任务中取得了显著进展，主要得益于视觉-语言连接器的优化和特定任务数据集的增加。通过将连接器升级为两层MLP，模型在处理视觉与语言关系时表现更佳。同时，引入如OKVQA、OCRVQA等数据集，增强了模型在复杂视觉推理任务中的能力。在11个基准测试中，LLaVA-1.5超越了现有方法，展示了其强大的多模态能力。此外，模型通过提升输入图像分辨率、扩展语言模型和改进多语言能力，进一步提升了性能。尽管在短格式回答任务中初期表现不佳，但通过调整提示格式和微调，其性能显著提升阅读详情

public void addOrder(Order order){

		try{

			String sql = "insert into orders(order_date,order_state,order_total,order_address,order_user_id,order_number,order_tel) values (?,?,?,?,?,?,?);";

			Timestamp timestamp = new Timestamp(order.getOrder_date().getTime());

			Object[] params = {timestamp,order.getOrder_state(),order.getOrder_total(),order.getOwner().getUser_address(),order.getOwner().getUser_id(),order.getOrder_number(),order.getOwner().getUser_tel()};

			qr.update(sql, params);

		}

		catch(SQLException e){

			throw new RuntimeException(e);

			

		}

	}

timestamp能获取到正确的值，但是会报如下异常，程序之前都能成功执行，突然报出这个异常
