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
<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
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;
}
}
