这是我上载时的首选。我认为让spring处理文件保存是最好的方法。Spring用它的
MultipartFile.transferTo(Filedest)功能来做。
import java.io.File;import java.io.IOException;import javax.servlet.http.HttpServletResponse;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestParam;import org.springframework.web.bind.annotation.ResponseBody;import org.springframework.web.multipart.MultipartFile;@Controller@RequestMapping("/upload")public class UploadController { @ResponseBody @RequestMapping(value = "/save") public String handleUpload( @RequestParam(value = "file", required = false) MultipartFile multipartFile, HttpServletResponse httpServletResponse) { String orgName = multipartFile.getOriginalFilename(); String filePath = "/my_uploads/" + orgName; File dest = new File(filePath); try { multipartFile.transferTo(dest); } catch (IllegalStateException e) { e.printStackTrace(); return "File uploaded failed:" + orgName; } catch (IOException e) { e.printStackTrace(); return "File uploaded failed:" + orgName; } return "File uploaded:" + orgName; }}
