Spring中文件上传,图片上传以及回显

Spring中文件上传

基于Spring 的图片上传以及回显

后台控制器实现

/**
 * 保存图片
 */
@RequestMapping("uploadify/uploadify")
@ResponseBody
private String uploadLogo(MultipartFile image) {
    String fileName = UploadUtil.upload(image, servletContext.getRealPath("/upload"));
    return "/upload/" + fileName;
}


/**
 *  上传文件工具类
 */
public class UploadUtil {

/**
 * @param file
 * @param basePath 上传文件的路径,通常都是/upload
 * @return
 */
public static String upload(MultipartFile file, String basePath){
    String originalFilename = file.getOriginalFilename();
    String fileName = UUID.randomUUID().toString()+"."+ FilenameUtils.getExtension(originalFilename);
    try {
        File targetFile = new File(basePath,fileName);
        FileUtils.writeByteArrayToFile(targetFile,file.getBytes());
    }catch (IOException e){
        e.printStackTrace();
    }
    return fileName;
 }
}
