/**
* 上传图片 -- 通过Map存取值
* @param request
* @param response
* @return
*/
public Map<String, String > uploadPic(HttpServletRequest request, HttpServletResponse response) {
Map<String, String > map=new HashMap<String, String>();
MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
Map<String, MultipartFile> fileMap = multipartRequest.getFileMap();
File picTempFile=null;
File tempDir=new File(getUploadBasePath() ,"");
if(!tempDir.exists())
tempDir.mkdirs();
for (Map.Entry<String, MultipartFile> entity : fileMap.entrySet()) {
MultipartFile file = entity.getValue();
String time = System.currentTimeMillis() + "";
picTempFile=new File(tempDir.getAbsolutePath(),time+"."+FileUtils.getExtend(file.getOriginalFilename()));
try{
if(picTempFile.exists())
org.apache.commons.io.FileUtils.forceDelete(picTempFile);
FileCopyUtils.copy(file.getBytes(),picTempFile);
}catch (Exception e){
e.printStackTrace();
}
map.put(entity.getKey(), "（默认保存路径）"+picTempFile.getName());
}
return map;
}
//获取上传根路径
private String getUploadBasePath(){
String path= ResourceUtil.getConfigByName("ck.servicefiles")+File.separator+"testBean"+File.separator+"template"+File.separator;
System.out.println(path);
return path;

}

ck.servicefiles：

取自配置文件sysConfig.properties中，即服务器的保存图片的路径
