MySQL 插入图片时出现com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException:

今天做向MySQL插入图片时出现这个异常：

弄了半天也没找出来错哪了，后来写了个独立的测试程序：

public static void inserImage() throws FileNotFoundException { DBAccess access=new DBAccess("insert into imagetable(image)values(?)",DBAccess.DBAccess_CONST.PREPARESTATEMENT); String filepath="d://snap2.bmp"; filepath="D://我的文档//workspace//AIForum//WebRoot//forum//img//defaultPhoto.gif"; System.out.println("文件路径："+filepath); File file=new File(filepath); InputStream inputStream=new FileInputStream(file); //InputStream inputStream=null; try { access.setBlob(1, inputStream); } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); } if(access.executePreparedStatement()) System.out.println("插入图片成功"); else System.out.println("插入图片失败"); }

插入snap2.bmp成功，但是换别的图片就是不行，我还以为是格式问题，但同样格式的其他bmp图片也不能成功，真是觉得奇怪。于是就在百度搜“插入图片 MySQLSyntaxErrorException”，终于找到一篇相同问题并有解决方案的文章：http://topic.youkuaiyun.com/u/20090715/00/9d4a9bd7-5a14-4c94-9d88-158202c07f07.html，文中提到将数据库编码GBK改为GB2312，我以前是GB2312，后看到GBK兼容繁体中文和简体中文，就在重建数据库时将数据库编码换为GBK了，没想到会出现这么个问题。http://blog.youkuaiyun.com/yakoo5/archive/2009/07/15/4349670.aspx这篇文章中提到这么一句话：MySQL将字符集设为GBK时，使用参数更新或插入中的字符串字段参数会引起异常，将字符集改为GB2312就可以了。

最终解决办法：

1.将数据库GBK编码改为GB2312；

2.重启MySQL服务。
