1.通过commons-fileupload来实现。导入相关jar包:commons-fileupload,commons-io
2.配置springmvc的配置解析器
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="defaultEncoding" value="utf-8"></property> <property name="maxUploadSize" value="10485760000"></property> <property name="maxInMemorySize" value="40960"></property> </bean>
3.jsp页面
<form action="upload.do" method="post" enctype="multipart/form-data"> file:<input type="file" name="file" /><input type="submit" value="submit"/> </form>
4.Controller代码
public class FileuploadController { @RequestMapping("/upload") public String fileupload(@RequestParam("file")CommonsMultipartFile file, HttpServletRequest req) throws IOException{ //获取文件名 file.getOriginalFilename(); String path = req.getRealPath("/fileupload");//获取上传文件的路径 InputStream is = file.getInputStream(); OutputStream os = new FileOutputStream(new File(path,file.getOriginalFilename())); int len = 0; byte[] buffer = new byte[400]; while((len=is.read(buffer)) != -1){ os.write(buffer, 0, len); } os.close(); is.close(); return "/index.jsp"; } }
