使用图片库插件在grails中保存大图像

Question

我正在为grails应用程序使用image-gallery插件。它可以保存小于2kb的小图像。但是当我尝试保存大图像时，它不会保存。甚至更大的4kb图像也无法保存。并显示以下异常：

Class
    java.sql.BatchUpdateException
Message
    ORA-24816: Expanded non LONG bind data supplied after actual LONG or LOB column 

以下是我的域名。我从图片库插件修改了：

package org.grails.plugins.imagegallery

import javax.swing.ImageIcon
import org.codehaus.groovy.grails.commons.ConfigurationHolder as CH

/**
 * Image holds the image bytes, its thumbnail and other properties related to an Image.
 * Image data field is required. Height, Width and thumbnail are created updating or creating an image.    
 */
class Image {
    byte[] thumbnail
    String caption
    String description
    byte[] data
    Integer width
    Integer height

    static mapping = {
        version(false)
        caption column: 'caption'
        description column: 'description'
        width column: 'width'
        height column: 'height'
        data column:'data',type:org.hibernate.type.MaterializedBlobType
        thumbnail column: 'thumbnail'
    }
    static constraints = {
        description(nullable: true)
        thumbnail(nullable: true)
        caption(nullable: true)
        data(maxSize:1073741824)
        width(nullable: true)
        height(nullable: true)
    }

    def beforeInsert = {
        java.awt.Image img = new ImageIcon(this?.data).getImage();
        this?.height = img.getHeight(null);
        this?.width = img.getWidth(null);
        loadThumbnail()
    }
    def beforeUpdate = {
        loadThumbnail()
    }



      /**
        * Creates the thumbnail. Takes maxWidth and maxHeight from config.groovy if provided
        *  otherwise cosiders the default max width & height as 170 & 120 respectively.
        */
        public void loadThumbnail() {
            if (this.data) {
                def imageUtil = new ImageUtil()
                imageUtil.load(data)
                float maxWidth = CH?.config?.grails?.imageGallery?.thumbnail?.maxWidth?:170
                float maxHeight = CH?.config?.grails?.imageGallery?.thumbnail?.maxWidth?:120
                imageUtil.thumbnailSpecial(maxWidth, maxHeight, 1,1)
                this.thumbnail = imageUtil.getBytes("JPEG")
            }
        }
    }

任何帮助都将不胜感激。

感谢。
