关于springmvc上传图片的方法小编给大家整理了两种方法,具体内容如下所示:
第一种:(放在该项目下的物理地址对应的位置)
a. 路径写法:
String basePath="/WEB-INF/resources/upload";
String filePathName= request.getSession().getServletContext().getRealPath(basePath);存放路径
b. 实际路径:
D:\WorkSpace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\XYT\WEB-INF\resources\upload\图片名称
c. 访问路径: http://localhost:8080/XYT/resources/upload/图片名称
d. 前提:只要这个项目能运行就行。
第二种:(创建虚拟路径,配置Tomcat下server.xml,创建存储路径和访问路径)
1.路径写法:
String filePathName=Constant.IMG_PATH+File.separator+"upload";
其中:public static final String IMG_PATH = "E:\\Java\\img";
2.路径配置:
Server.xml配置
1 2 3 4 5 6 7 8 | <Host name= "localhost" appBase= "webapps" unpackWARs= "true" autoDeploy= "true" > <Valve className= "org.apache.catalina.valves.AccessLogValve" directory= "logs" prefix= "localhost_access_log." suffix= ".txt" pattern= "%h %l %u %t " %r " %s %b" /> <!-- add(save pictures) --> <Context path= "/upload" docBase= "E:\Java\img\upload" ></Context> </Host> |
3.实际路径:E:\Java\img\upload
4.访问路径:http://localhost:8080/upload/图片名称
5.参考:http://my.oschina.net/pingdy/blog/381001
6.前提:必须打开Tomcat服务器
举例:上传图片的实例:(可以上传多张图片)
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 | JSONObject rs= new JSONObject(); CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver( request.getSession().getServletContext()); String url= "" ; if (multipartResolver.isMultipart(request)) { MultipartHttpServletRequest multiRequest = (MultipartHttpServletRequest) request; Iterator<String> iter = multiRequest.getFileNames(); while (iter.hasNext()) { MultipartFile file = multiRequest.getFile((String) iter.next()); if (file != null) { String originalFileName = file.getOriginalFilename(); String[] f = originalFileName.split( "\\." ); String ext = "" ; if (f!=null && f.length>1){ ext = f[f.length-1]; System.out.println(ext); } System.out.println(allowImgType==null); if (!allowImgType.contains(ext.toUpperCase())){ rs.put( "code" , "ERR_UPLOAD_0003" ); rs.put( "msg" , "类型错误" ); return rs; } //String basePath="/WEB-INF/resources/upload";//String filePathName = request.getSession().getServletContext().getRealPath(basePath); String filePathName=Constant.IMG_PATH+File.separator+ "upload" ; url = filePathName; System.out.println(url); //上传后记录在path这个路径下。 File localFile = new File(filePathName); if (!localFile.exists()){ localFile. mkdir (); } //compress String fname = new Date ().getTime()+ "." +ext; String originalFname = fname.substring(0,fname.indexOf( "." ))+ "_original." +ext; String fileName = filePathName + File.separator + fname; String oFileName = filePathName + File.separator + originalFname; File infile = new File(fileName); File oFile = new File(oFileName); try { ImageHelper.compress(file.getInputStream(), 600, infile); file.transferTo(oFile); //original 上传原图 JSONObject obj = new JSONObject(); rs.put( "code" , Constant.CODE_SUCCESS); rs.put( "data" , obj.toString()); } catch (Exception e){ rs.put( "code" , "ERR_UPLOAD_0001" ); rs.put( "msg" , "ERR_UPLOAD_0001" ); e.printStackTrace(); return rs; } } |
