基于spring 的ssi-uploader的多图片上传

本文主要是介绍基于spring 的ssi-uploader的多图片上传，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

今天帮一个朋友做了一个多图片上传的demo，前端插件用的是ssi-uploader，后台是spring，详细看代码：

package com.controller;import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Map;import javax.servlet.ServletContext;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.multipart.MultipartFile;
import org.springframework.web.multipart.MultipartHttpServletRequest;
import org.springframework.web.multipart.commons.CommonsMultipartFile;

@Controller
@RequestMapping("upload")
public class FileUploadUtil {@Autowiredprivate FileUploadUtilService service;@RequestMapping("testFileUpload")@ResponseBodypublic String testFileUpload(HttpServletRequest request,HttpServletResponse response,Map<String, Object> model){MultipartHttpServletRequest Murequest = (MultipartHttpServletRequest)request;Map<String, MultipartFile> files = Murequest.getFileMap();//得到文件map对象String upaloadUrl ="D:/upload/photo/";//得到当前工程路径拼接上文件名File dir = new File(upaloadUrl);if(!dir.exists())//目录不存在则创建dir.mkdirs();for(MultipartFile file :files.values()){String  fileName=file.getOriginalFilename();//相片的名字File tagetFile = new File(upaloadUrl+fileName);//创建文件对象if(!tagetFile.exists()){//文件名不存在 则新建文件，并将文件复制到新建文件中try {tagetFile.createNewFile();} catch (IOException e) {e.printStackTrace();}try {file.transferTo(tagetFile);//到这里就可以上传了，以下是处理图片及允许gif的上传//图片扩展名String types=fileName.substring(fileName.lastIndexOf(".")+1).toLowerCase();//以1024*768大小改变图片,如果是gif则放开限制，如果需要存储原图则不需要处理if(!types.contains("gif")){
//                       Thumbnails.of(tagetFile).size(1024,768).toFile(tagetFile);}} catch (IllegalStateException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}}}return "根据需要返回的页面";}
}

前端页面：

<%@ page language="Java" import="java.util.*" pageEncoding="utf-8"%>
<%    String path = request.getContextPath();String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort()+ path + "/";String error = (String) request.getAttribute("error0");
%>

</html>

最后别忘了要注解spring的MultipartResolver

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="maxUploadSize"> <value>104857600</value> </property> <property name="maxInMemorySize"> <value>4096</value> </property> <property name="defaultEncoding"> <value>UTF-8</value> </property> </bean>
