SpringMVC图片上传

配置文件为：

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">

<property name="defaultEncoding" value="UTF-8" />

<property name="maxUploadSize" value="200000" />

</bean>

controller层的编写：

@RequestMapping("/###")

public String tupianTest1(@RequestParam("photo") MultipartFile photo,HttpServletRequest request) throws IOException {

System.out.println("===into tupianTest1====");

// 取得上传文件的内容

byte[] content = null;

content = photo.getBytes();

System.out.println("上传内容" + content[1]);

// 取得上传到服务器上的文件路径

String path = request.getSession().getServletContext()

.getRealPath("/upload");

// LogUtil.debug(log, "上传图片的存储位置是：%s", path);

System.out.println("图片上传路径" + path);

// 判断上传路径是否存在

File uploadPath = new File(path);

if (!uploadPath.exists()) {

uploadPath.mkdir();

}

// 为上传的文件重命名，用vo中的id替代原始的文件名

String filename = photo.getOriginalFilename();

String exName = filename.substring(filename.lastIndexOf("."));

String newFileName = System.currentTimeMillis() + exName;

System.out.println("图片名字：" + newFileName);

// 组装上传文件新文件名及上传路径

String imgUrl = "/upload/" + newFileName;

System.out.println("上传路径：" + imgUrl);

// 执行上传

FileUtils.writeByteArrayToFile(new File(path + "/" + newFileName),

content);

System.out.println("上传成功！");

return "###";

}

jsp页面的编写：

<form action="###" method="post" enctype="multipart/form-data" >

<center>

<input type="file" name="photo" />

<button type="submit">提交</button>

</center>

</form>
