spring mvc和structs2的文件上传有区别的：

structs2可参考 https://www.cnblogs.com/wkrbky/p/5904787.html

spring mvc直接上代码：

import java.io.File;import javax.servlet.http.HttpServletRequest;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestParam;import org.springframework.web.multipart.MultipartFile;@Controllerpublic class FileUploadController {	//单文件	@RequestMapping("/upload")	public String uploadFile(@RequestParam("file1") MultipartFile file1,HttpServletRequest request)throws Exception{		String filePath=request.getServletContext().getRealPath("/");		System.out.println(filePath);		file1.transferTo(new File(filePath+"upload/"+file1.getOriginalFilename()));		return "redirect:success.html";	}	//多文件：文件列表	@RequestMapping("/upload2")	public String uploadFiles(@RequestParam("file") MultipartFile[] files,HttpServletRequest request)throws Exception{		String filePath=request.getServletContext().getRealPath("/");		System.out.println(filePath);		for(MultipartFile file:files){			file.transferTo(new File(filePath+"upload/"+file.getOriginalFilename()));					}		return "redirect:success.html";	}}
