JAVA_WEB批量上传文件到阿里云OS

JAVA_WEB批量上传文件到阿里云OS

1.  概述

从网页添加图片上传到阿里云OS服务器;

实现想法:先把文件上传到服务器所在位置,再把文件上传到阿里云OS;

以下是代码实现,主要是把图片批量上传到OS再跟进url在网页展示图片;

2.  代码实现(springmvc+spring)

2.1 Controller

package com.pro.huanbao.upimage.controller;

 

import org.springframework.stereotype.Controller;

 

import java.io.File;

import java.util.ArrayList;

import java.util.List;

import java.util.UUID;

 

import javax.servlet.http.HttpServletRequest;

 

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.annotation.RequestParam;

import org.springframework.web.multipart.MultipartFile;

 

 

@Controller

public class UploadImageController {

 

    @RequestMapping(value = "/uploadImages", method = RequestMethod.POST)

    private String fildUpload(

            @RequestParam(value ="file", required =false) MultipartFile[]file,

            HttpServletRequest request)throws Exception {

        // 上传图片到本地

       

        // 获得物理路径webapp所在路径

        String pathRoot = request.getSession().getServletContext()

                .getRealPath("");

        String path = "";

        List<String> listImagePath =new ArrayList<String>();

        for (MultipartFilemf :file) {

            if (!mf.isEmpty()) {

                // 生成uuid作为文件名称

                String uuid = UUID.randomUUID().toString().replaceAll("-","");

                // 获得文件类型（可以判断如果不是图片，禁止上传）

                String contentType =mf.getContentType();

                // 获得文件后缀名称

                String imageName =contentType.substring(contentType

                        .indexOf("/") + 1);

                path = "/static/images/" + uuid + "." + imageName;

                mf.transferTo(new File(pathRoot +path));

               

                // 调用方法把上传到本地的图片上传到OS

                String url = getImageUrl(request,path,uuid +"." +imageName);

                listImagePath.add(url);

            }

        }

        request.setAttribute("imagesPathList",listImagePath);

       

        return"show";

    }

 

    /**

    private String getImageUrl(HttpServletRequestrequest, Stringpath,StringfileName) {

        @SuppressWarnings("deprecation")

        String realPath = request.getRealPath(path);

        String endPath = realPath.replace("\\", "\\\\");

        File file = new File(endPath);

        // 上传本地图片到OS

        String url = OssClientUtil.uploadPic(file,fileName);

        // 删除本地图片

        file.delete();

        returnurl;

    }

 

    // 因为我的JSP在WEB-INF目录下面，浏览器无法直接访问

    @RequestMapping(value = "/index")

    private String forward() {

        return"index";

    }

 

 

}

 

2.2  OssUtil

        returnossClientUtil;

    }

 

    /**

    public static String uploadPic(File file, Stringkeys) {

        OSSClient ossClient = new OSSClient(endpoint,accessKeyId,

                accessKeySecret);//连接oss云存储服务器

        ossClient.putObject(bucket,keys,file);

        String url = String.valueOf(getUrl(keys));

    }

                * 365 * 10);// url超时时间

        // 生成URL

        URL url = server.generatePresignedUrl(bucket,key,expirations);

        server.getEndpoint();

        // 关闭client

        server.shutdown();

        returnurl;

    }

 

}
