怎么读取一个图片流放到

[coolzdp]

getpic.jsp 里读取服务器的某个图片

package com.tarring.pojo;

import java.io.IOException;
import java.io.InputStream;
import java.sql.Date;
import java.util.List;

import org.hibernate.Transaction;

import com.tarring.hibernate.HibernateUtil;

public class Test {
	public static void main(String[] args) {
		Test test = new Test();
		//消费者对象创建
		Customer customer = new Customer("U00010", "tarringint");
		ICustomerDAO dao = new CustomerDAO();

		customer.setBirthday(Date.valueOf("1988-08-08"));

		// 插入图片
		InputStream in = test.getClass().getResourceAsStream("image.jpg");

		try {
			byte[] buffer = new byte[in.available()];
			in.read(buffer);
			customer.setImage(buffer);
		} catch (IOException e) {
			e.printStackTrace();
		}

		/**
		 * 保存记录
		 */
		// dao.save(customer);// insert into t24.customer (UserName, Birthday,
		// Image, CustomerId) values (?, ?, ?, ?)
		/**
		 * 删除指定的记录(根据ID)
		 */
		// dao.delete(customer);//delete from t24.customer where CustomerId=?
		/**
		 * 查找指定的记录(根据ID值)
		 */
		// Customer cus = dao.findById("U00002");
		// System.out.println(cus.getUserName());
		
		Transaction ts = HibernateUtil.getSession().beginTransaction();
		Customer customer1 = new Customer();
		customer1.setUserName("updatedao");
		customer1.setCustomerId("U00001");
		dao.update(customer1);
		ts.commit();
		HibernateUtil.closeSession();
		
		
		/**
		 * 查找所有的记录
		 */
		// List<Customer> customerList = dao.findAll();
		// for (Customer customer2 : customerList) {
		// System.out.println(customer2.getCustomerId() + " ======== "
		// + customer2.getImage());
		// }
	}

}

这个是用Hibernate读取一个图片到数据库，数据库中的该字段类型为二进制型，给你做为参考！希望对你有帮助！
