java接收ios文件上传的示例代码
本文实例为大家分享了java如何接收ios文件上传的具体代码,供大家参考,具体内容如下
iosMultipart/form-dataPOST请求java后台spring接口一直出错,搞了两天,终于解决了,积累下来
packagecom.xx.controller; importjava.io.FileOutputStream; importjava.io.IOException; importjava.io.InputStream; importjava.util.Iterator; importjava.util.LinkedList; importjava.util.List; importjavax.servlet.http.HttpServletRequest; importjavax.servlet.http.HttpServletResponse; importorg.apache.commons.fileupload.FileItem; importorg.apache.commons.fileupload.FileUploadException; importorg.apache.commons.fileupload.disk.DiskFileItemFactory; importorg.apache.commons.fileupload.servlet.ServletFileUpload; importorg.springframework.stereotype.Controller; importorg.springframework.web.bind.annotation.RequestMapping; importorg.springframework.web.bind.annotation.RequestMethod; importorg.springframework.web.bind.annotation.ResponseBody; importcom.nupaApp.model.FileMeta; @Controller @RequestMapping("/controller") publicclassFile1Controller{ LinkedListfiles=newLinkedList (); FileMetafileMeta=null; /*************************************************** *URL:/rest/controller/uploadupload():receivesfiles * *@paramrequest *:MultipartHttpServletRequestautopassed *@paramresponse *:HttpServletResponseautopassed *@returnLinkedList asjsonformat *@throwsIOException *@throwsFileUploadException ****************************************************/ @RequestMapping(value="/upload",method=RequestMethod.POST) @ResponseBody publicStringupload(HttpServletRequestrequest,HttpServletResponseresponse) throwsIOException,FileUploadException{ booleanisMultipart=ServletFileUpload.isMultipartContent(request);//判断是否是表单文件类型 DiskFileItemFactoryfactory=newDiskFileItemFactory(); ServletFileUploadsfu=newServletFileUpload(factory); Listitems=sfu.parseRequest(request);//从request得到所有上传域的列表 for(Iteratoriter=items.iterator();iter.hasNext();){ FileItemfileitem=(FileItem)iter.next(); if(!fileitem.isFormField()&&fileitem!=null){//判读不是普通表单域即是file //操作fileitem文件步骤,可以获取大小、路径 //定义图片输出路径 StringimgPath="e:"+System.currentTimeMillis()+".jpg"; //定义图片流 InputStreamfin=fileitem.getInputStream(); //定义图片输出流 FileOutputStreamfout=newFileOutputStream(imgPath); //写文件 byte[]b=newbyte[1024]; intlength=0; while((length=fin.read(b))>0){ fout.write(b,0,length); } //关闭数据流 fin.close(); fout.close(); } } return"200"; } }
pom.xml添加
commons-fileupload commons-fileupload 1.3.1 commons-io commons-io 2.4
spring-config.xml添加bean
