JSP + MySQL+Servlet+JavaBean 实现图片上传

通过JSP录入本地图片，MySQL建库，图片以blob值上传数据库，JavaBean封装对象。我上传的是整个项目的代码，并附加使用教程，简单易用。

package lab8;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public class DBUtil {
    public static final String DRIVER_CLASS_NAME = “com.mysql.jdbc.Driver“;
    public static final String URL = “jdbc:mysql://localhost:3306/img?useUnicode=true&characterEncoding=UTF-8“;
    public static final String USERNAME = “root“;
    public static final String PASSWORD = “123456“;

    static {
        try {
            Class.forName（DRIVER_CLASS_NAME）;
		    System.out.println（“加载驱动成功！“）;
        }catch （ClassNotFoundException e）{
            System.out.println（“找不到sql驱动“）;
            e.printStackTrace（）;
        }
    }

    public static Connection getConnection（） throws SQLException{
        return DriverManager.getConnection（URL USERNAME PASSWORD）;
    }

    public static void closeConnection（Connection connection）{
        if（connection != null）{
            try {
                connection.close（）;
            }catch （SQLException e）{
                System.out.println（“关闭数据库失败“）;
                e.printStackTrace（）;
            }
        }
    }
}
