使用java将图像作为blob上载到sql数据库

我有一个这样设置的数据库

  CREATE TABLE item (             
              ItemID int(11) NOT NULL auto_increment,  
              ItemName char(25),      
              YearManufactured int(11),   
              CopiesSold int(11),
              AmountInStock int(11),
              image blob,                         
              Description char(30),     
              PRIMARY KEY  (`ItemID`)                   
     );

这个表工作得很好，我可以很好地插入和删除它。我希望将我的代码组织得有点不同，并使用Java，而不是编写scriplets来更新表。我想切换到这样做的最初原因是因为我想能够更轻松地上传图像。这是我的代码：

这是最初打开的便签。URL、用户ID和密码绝对正确

<%  
    // Instantiating the connection to the database
    String mysJDBCDriver = "com.mysql.jdbc.Driver"; 
    String mysURL = "MY_ADDRESS"; 
    String mysUserID = "USERNAME"; 
    String mysPassword = "PASSWORD";

    java.sql.Connection conn=null; // a new connection
    try 
    {
        DB db = new DB();
        conn=db.dbConnect(mysJDBCDriver, mysURL,mysUserID,mysPassword);
        db.insertImage(conn,"c:/Users/DPiganell/image_launch_a5.jpg");
        db.getImageData(conn);
        System.out.println("Connected successfully to database using JConnect");
        session.setAttribute("connection", conn);

     }
    catch(Exception e)
    {
        e.printStackTrace();
        out.print(e.toString());
    }

%>

一旦程序到达executeUpdate，就会抛出异常。感谢您的帮助。如果比较容易的话，我愿意采取不同的方法

您的查询语法看起来有误，请检查左括号和右括号。

SQLExpection怎么说？从您发布的stacktrace中，您的错误是在编写文件时，而不是在执行SQL代码时。@Perception以什么方式？地址绝对正确。从异常粘贴的内容在其完整形式中会更有用。从外观上看，您的FileOutputStream实际上是异常抛出器，因此SQL的东西工作得很好。@Iselkies-如果没有完整的stacktrace，这是不可能的，但是java.io.FileOutputStream.write（FileOutputStream.java:305）中的这些行

，severy:at DBPackage.DB.getImageData（DB.java:85）

清楚地显示调用了

getImageData

方法，然后在FileOutputStream上调用了

write

。我要检查两件事，1）您的文件字节不为空，2）目标文件不存在。
