本文使用的文件上传基于SSM框架中自带的文件上传机制，不懂原理，先将代码放在这里，只作测试及以后使用参考
编写前台test.jsp

简单的表单，并且有一个尝试获取的字段name
后台Controller
package com.pandawork.web.controller;
import com.pandawork.web.spring.AbstractController;
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;
import org.springframework.web.multipart.MultipartHttpServletRequest;
import org.springframework.web.multipart.commons.CommonsMultipartResolver;
import javax.servlet.http.HttpServletRequest;
import java.io.File;
import java.io.IOException;
import java.util.Iterator;

@Controller
@RequestMapping("/file")
public class FileController extends AbstractController{
@RequestMapping(value = "/to/test")
public String toTest(){
return "/file/test";
}
@RequestMapping(value = "/upload")
public String springUpload(HttpServletRequest request, @RequestParam("name") String name) throws IllegalStateException, IOException
{
//将当前上下文初始化给 CommonsMutipartResolver （多部分解析器）
CommonsMultipartResolver multipartResolver=new CommonsMultipartResolver(
request.getSession().getServletContext());
//检查form中是否有enctype="multipart/form-data"
if(multipartResolver.isMultipart(request)) {
//将request变成多部分request
MultipartHttpServletRequest multiRequest=(MultipartHttpServletRequest)request;
//获取multiRequest 中所有的文件名
Iterator iter=multiRequest.getFileNames();
while(iter.hasNext()) {
//一次遍历所有文件
MultipartFile file=multiRequest.getFile(iter.next().toString());
if(file!=null) {
String path="E:/springUpload"+"/"+file.getOriginalFilename();
//上传
file.transferTo(new File(path));
}
}
}
System.out.println(name);
return "/success";
}
}
将文件保存至E盘下的springUpload文件夹下
