springMVC+jersey实现跨服务器文件上传

1.首先添加所需要的jar包

   

 

2.在springMVC的配置文件中添加文件上传解析器

  <!-- 文件上传的解析器 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!-- 文件上传大小的限制 --> <property name="maxUploadSize" value="5000000"></property> <property name="defaultEncoding" value="UTF-8"></property> </bean>

3.jsp页面

<form id="fm" action="" method="post"><p><img src="" alt="" id="imgSrc"/>请上传头像：<input type="file" name="imgFile" id="imgFile" onchange="fileUpload();"/><input type="hidden" id="reletivePath" name="reletivePath" value=""></p></form>

4.文件上传的 js

<!-- 文件上传js --><script type="text/javascript">function fileUpload(){var option = {type:"POST",url:"${pageContext.request.contextPath }/user/fileUpload.do",data:{fileName:"imgFile"},success:function(reData){alert(reData.reletivePath);$("#imgSrc").attr("height",100);$("#imgSrc").attr("width",100);$("#imgSrc").attr("src",reData.fullPath);$("#reletivePath").val(reData.reletivePath);},dataType:"json"};$("#fm").ajaxSubmit(option);}</script>

5. controller

    /* * 文件上传 */@RequestMapping("fileUpload")public @ResponseBody Map<String , String> fileUpload(HttpServletRequest request,String fileName){System.out.println(111);//1.将普通请求转换为多部件请求MultipartHttpServletRequest mr = (MultipartHttpServletRequest)request;//2.根据文件名获取文件对象CommonsMultipartFile mf = (CommonsMultipartFile)mr.getFile(fileName);//3.获取文件全名称String originalFilename = mf.getOriginalFilename();System.out.println("文件全名称"+originalFilename);//4.获取后缀String suffix = originalFilename.substring(originalFilename.lastIndexOf("."));System.out.println("后缀"+suffix);//5.将文件对象转换为字节byte[] fileBytes = mf.getBytes();//6.获取新的随机文件名String newFileName="";SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddHHmmssSSS");int num = (int)(Math.random()*899)+100;newFileName = sdf.format(new Date())+num;System.out.println("新的随机文件名"+newFileName);//开始上传//1.创建jesy服务器Client client = Client.create();String fullPath = "http://localhost:8088/fileServiceProject/upload/"+newFileName+suffix;//把文件关联到远程服务器WebResource wr = client.resource(fullPath);//2.相对路径String reletivePath = "/upload/"+newFileName+suffix;//3.上传wr.put(String.class, fileBytes);Map<String , String> map = new HashMap<String, String>();map.put("fullPath", fullPath);map.put("reletivePath", reletivePath);return map;}
