通过Spring+Mybatis+Mysql搭建了一个框架，在向MYSQl插入图片信息时，将其保存为BLOB类型到数据库。

前台JAVA代码如下：

@RequestMapping("/zdfz")

public ModelAndView zdfz(HttpServletRequest request,HttpServletResponse response){

ModelAndView mav = new ModelAndView("test");

//封装前台的字段到Map

HashMap map = new HashMap();

map.put("id", UUID.randomUUID().toString());

map.put("name", request.getParameter("name"));

map.put("age", request.getParameter("age"));

map.put("sex", request.getParameter("sex"));

//

MultipartHttpServletRequest msRequest = (MultipartHttpServletRequest) request;

MultipartFile mfile = msRequest.getFile("tp");

try {

//封装图片到Map

map.put("descrip",mfile.getBytes());

} catch (IOException e) {

e.printStackTrace();

}

int count = ts.insertFZ(map);

return null;

}

Mybatis的XML文件(descrip就是图片文件字段，数据类型为ＢＬＯＢ)：

insert into user

(

id,name,age,

sex,descrip

)

value

(

#{id},#{name},#{age},

#{sex},#{descrip,jdbcType=BLOB}

)

报错如下：

说明：如果不添加这个BLOB字段，就可以正常的插入。

插入的时候并没有将相关的字段封装成一个JavaBean，而是封装成一个Map插入的。

经过在网上搜索相关的资料，也没有解决，希望各位帮忙。
