java 使用框架Spring MVC批量上传图片
运行环境：jdk1.8.0_17+tomcat 8 + spring：4.3.4+mybatis：3.2.7+ eclipse ide 2018+maven管理
最近写项目时候用到上传图片文件等功能之前写过没有总结，以及记录等，今天总结下写的批量上传图片功能
前段只需要把所有的选择的图片提交上来即可，后台会逐个处理，并且会在服务器或者当前电脑自己新建一个存放图片的文件夹，在application.properties配置里面你可以指定你所存放图片的路径，存图片的文件夹，缩略图的路径，以及缩略图的文件夹。
功能实现效果：
上传图片的Controller方法：
/**
* 上传图片发布宝贝的控制器
* @return 图片缩略图imageList
* @throws IOException
* @throws FileNotFoundException
*/
@RequestMapping("/releaseBaby")
public Object UploadPictree(@RequestParam("upload_file")CommonsMultipartFile[] files,@RequestParam("product") String JSON_prduct,HttpServletRequest request,HttpSession session) throws FileNotFoundException, IOException {
//获取前台传过来的图片，和JSON字符串，这里需要转化成自己的po类到处需要在网上找JSON的几个包才能完成转化
JSONObject jsonObject = JSONObject.fromObject(JSON_prduct);
//将字符串JSON数据转化成自己的po 类
Product product = (Product)JSONObject.toBean(jsonObject, Product.class);
//获取配置文件中的路径
ResourceBundle resource = ResourceBundle.getBundle("application");
Map<String, Object> map = new HashMap<String, Object>();
String imageURL = null ;
map.put("title","false");
// //设置需要存的图片地址
String pictureStorageAddress = resource.getString("realUploadPath")+request.getContextPath();
System.err.println("图片存放地址："+pictureStorageAddress);
//设置缩略图存放地址
String thumbanilStorageAddress = resource.getString("realThumbnailPath")+request.getContextPath();
System.err.println("缩略图存放地址："+thumbanilStorageAddress);
//循环取出图片
for (CommonsMultipartFile cmf : files) {
//获取文件全名
String fileName = cmf.getOriginalFilename();
String extensionName = fileName.substring(fileName.lastIndexOf(".")+1);
System.out.println("获取的扩展名："+ extensionName);
String newFileName = String.valueOf(System.currentTimeMillis())+"."+extensionName;
System.out.println("新的图片名称："+newFileName);
// 存入图片后获得原图的相对地址,将相对地址存入数据库
imageURL= uploadPicturesService.uploadPictures(cmf, pictureStorageAddress, newFileName);
System.err.println("原图相对地址："+imageURL);
// 获取缩略图的相对地址返回给前段使用
String thumbanilImageURL = thumbnailService.generateThumbnail(cmf, thumbanilStorageAddress, newFileName);
System.err.println("缩略图相对地址："+imageURL);
}
//获取原图的绝对路径
String storePictureFolder =pictureStorageAddress+request.getContextPath()+resource.getString("storePictureFolder");
System.out.println("原图的绝对路径："+ storePictureFolder);
//获取缩略图的绝对路径
String realThumbanilPath =thumbanilStorageAddress+request.getContextPath()+resource.getString("thumbnailPictureFolder");
System.out.println("缩略图的绝对路径："+ realThumbanilPath);
//读取上传图片的图片
List<String> realImageList = new ArrayList<String>();
//获取缩略图里面的所有图片
realImageList = ProductImageListImpl.printFile(realThumbanilPath);
//设置返回的imageList缩略图
map.put("realImageList", realImageList);
/**
* 设置图片相对地址到数据库以及日期用户等
*/
String userInfo = (String) session.getAttribute("userInfo");
String userInfo1 = (String) request.getSession().getAttribute("userInfo");
System.out.println("Session值1"+userInfo +"Session值2"+userInfo1);
product.setProductImage(imageURL);
product.setProductDeliverytime(CustomDate.getPresentTime());
// //插入到数据库
int temp = productService.inserProduct(product);
if (temp > 0) {
System.out.println("发布宝贝成功，已插入数据库！");
map.put("message", "恭喜发布宝贝成功！");
map.put("title", true);
}
return map;
}
uploadPictures 上传图片的实现方法:
/**
* 上传图片并返回图片的相对地址
* @throws IOException
*/
@Override
public String uploadPictures(CommonsMultipartFile file, String realUploadPaht, String newFileName)
throws IOException {
ResourceBundle resource = ResourceBundle.getBundle("application");
String storePictureFolder = resource.getString("storePictureFolder");
//如果目录不存在创建目录
File uploadFile = new File(realUploadPaht+storePictureFolder);
if (!uploadFile.exists()) {
System.err.println(uploadFile.exists());
uploadFile.mkdirs();
}
//创建输入流
InputStream inputStream = file.getInputStream();
//生成输出地址URL realUploadPaht=绝对路径，storePictureFolder=存放图片的文件夹名 +文件的名字 +file.getOriginalFilename()
String outPutPath = realUploadPaht+storePictureFolder +"/"+ newFileName;
//创建输出流 以及新文件名
OutputStream outputStream = new FileOutputStream(outPutPath);
//设置缓冲区
byte[] buffer = new byte[1024];
//输入流读入缓冲区，输出流从缓冲区写出
while (inputStream.read(buffer)>0) {
outputStream.write(buffer);
}
outputStream.close();
//返回原图上传的相对地址
String relative_address = storePictureFolder +"/"+ newFileName;
return relative_address;
}
生成缩略图的实现方法：
/**
* 生成简约图的方法
* @author TangLie
*
*/
@Service
public class ThumbnailServiceImpl implements ThumbnailService{
//设置节约图的宽度以及高度
public static final int heigth = 100;
public static final int width = 100;
@Override
public String generateThumbnail(CommonsMultipartFile file, String realUploadPaht,String newFileName) throws IOException {
// TODO Auto-generated method stub
ResourceBundle resource = ResourceBundle.getBundle("application");
String thumbnailPictureFolder = resource.getString("thumbnailPictureFolder");
//如果目录不存在创建目录
File uploadFile = new File(realUploadPaht+thumbnailPictureFolder);
if (!uploadFile.exists()) {
uploadFile.mkdirs();
}
//缩略图保存的绝对地址
String des = realUploadPaht+thumbnailPictureFolder+"/"+newFileName;
//按照我给的宽高生成缩略图
Thumbnails.of(file.getInputStream()).size(width, heigth).toFile(des);
//返回缩略图地址
String relative_address = thumbnailPictureFolder+"/" + newFileName;
return relative_address;
}
}
