SpringMVC多个文件上传及上传后立即显示图片功能

多文件上传就是改良一个方法把MultipartFile类换成CommonsMultipartFile类，因为上传多个文件用数组方式的话MultipartFile类不能初始化，它不支持数组

package com.meng.upload;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import javax.servlet.http.HttpServletRequest;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.multipart.MultipartFile;
import org.springframework.web.multipart.commons.CommonsMultipartFile;
@Controller
public class upload {
  @RequestMapping(value="/upload",method=RequestMethod.POST)
  public String upload(@RequestParam("file1") CommonsMultipartFile[] file1, HttpServletRequest request) {
    for (CommonsMultipartFile commonsMultipartFile : file1) {
      try {
 File file = new File(request.getServletContext().getRealPath("upload"),
     System.currentTimeMillis() + "_"
  + commonsMultipartFile.getOriginalFilename());
 System.out.println(file.getPath()+"");
 FileOutputStream fileOutputStream = new FileOutputStream(file);
 fileOutputStream.write(commonsMultipartFile.getBytes());
 fileOutputStream.close();
      } catch (Exception e) {
 // TODO Auto-generated catch block
 e.printStackTrace();
      }
    }
    return "ok";
  }
}
