SpringMVC上传图片与访问
|
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"; b. 实际路径: D:WorkSpace.metadata.pluginsorg.eclipse.wst.server.coretmp0wtpwebappsXYTWEB-INFresourcesupload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:Javaimg"; 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:Javaimgupload"></Context> </Host> 3.实际路径:E:Javaimgupload 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)
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;
}
}
