二、修改控制器
多文件上传的逻辑与单文件类似只是其基础上接收部分多了文件数组再遍历一回完成如下
package org.sang.cc;import java.io.File;
import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.UUID;import javax.servlet.http.HttpServletRequest;import org.springframework.util.ResourceUtils;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;RestController
public class FileUploadController {SimpleDateFormat sdfnew SimpleDateFormat(yyyy/MM/dd);PostMapping(/upload)public String upload(MultipartFile[] uploadFile,HttpServletRequest req){try {//String realPathreq.getSession().getServletContext().getRealPath(/);String realPathResourceUtils.getURL(classpath:).getPath(); String formatsdf.format(new Date());System.out.println(realPath:realPathstatic/format);File foldernew File(realPathstatic/format);if(!folder.isDirectory()){folder.mkdirs();}String[] filePathnew String[uploadFile.length];String s;for(int i0;iuploadFile.length;i){String oldNameuploadFile[i].getOriginalFilename();String newNameUUID.randomUUID().toString()oldName.substring(oldName.lastIndexOf(.),oldName.length());uploadFile[i].transferTo(new File(folder,newName)); filePath[i]req.getScheme()://req.getServerName():req.getServerPort()/static/format/newName; sfilePath[i] br;} return s;}catch(IOException e){e.printStackTrace();}return 上传失败!;}
}三、运行结果 上传页 接收页 展示页
