5分钟解决阿里云oss对象存储

5分钟解决阿里云OSS对象存储

1. 后附关键代码

启动代码如下：
pom.xml里添加依赖

com.aliyun.oss aliyun-sdk-oss 2.8.3 1.建类AliyunOSSClientUtil package io;

import com.aliyun.oss.OSSClient;

import java.io.File;

/**

• Created by JYZ on 2018/9/8.
  */
  public class AliyunOSSClientUtil {
  private static String endpoint=“oss-cn-beijing.aliyuncs.com”;
  private static String accessKeyId=“LTAIpdrTtP1vBwWO”;
  private static String accessKeySecret=“M2iBekT7WieHo7AVAMT0tLqV7NZjtw”;
  private static String bucketName=“1529922940”;
  public static void addPicture(String keyPicture,String pathPicture){
  String key=keyPicture;//上传上去的名称
  // 创建OSSClient实例
  OSSClient ossClient = new OSSClient(endpoint,accessKeyId,accessKeySecret);
  //需要上传的图片路径
  String path=pathPicture;
  // 上传文件
  ossClient.putObject(bucketName,key,new File(path));
  //关闭client
  ossClient.shutdown();
  }
  }
  2.建类AliyunOssDownLoadUtil
  package io;

import com.aliyun.oss.OSSClient;
import com.aliyun.oss.model.GetObjectRequest;
import java.io.File;
import java.io.IOException;

/**

• Created by JYZ on 2018/9/8.
  */
  public class AliyunOssDownLoadUtil {
  public static void main(String[] args) throws IOException {
  String endpoint=“oss-cn-beijing.aliyuncs.com”;
  String accessKeyId=“LTAIvXc31CJ6DrY3”;
  String accessKeySecret=“S2FSwJXs9u7aEPDWgBXKh5Xh6iJT0Y”;
  String bucketName=“1529922940”;
  OSSClient ossClient = new OSSClient(endpoint,accessKeyId,accessKeySecret);
  ossClient.getObject(new GetObjectRequest(bucketName,“OSSProject/e.png”),new File(“F:\OSSPictureDownLoad\e.png”));
  System.out.println(“下载成功”);
  ossClient.shutdown();
  }
  }
  3.Controller里的调用代码：
  public Map<String, Object> fileUpload(HttpServletRequest request,
  @RequestParam(“file”) MultipartFile file) {
  Map<String, Object> map = new HashMap<String, Object>();

   HttpSession session = request.getSession();
       User user = (User) session.getAttribute("user");
   if (user == null || user.getType() == 0) {
       map.put("code", -1);
       return map;
   }
  
   if (!file.isEmpty()) {
       try {
           //取得当前上传文件的文件名称
           String myFileName = file.getOriginalFilename();
           //如果名称不为“”,说明该文件存在，否则说明该文件不存在
           if (myFileName.trim() != "") {
               System.out.println(myFileName);
               Date d = new Date();
               SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd-HH-mm-ss");
               //重命名上传后的文件名
               String fileName = "OSSPicture/"+sdf.format(d) + "-" + file.getOriginalFilename();
               //定义上传路径
               String path = "D:\\bossPic\\" + fileName;
               File localFile = new File(path);
               file.transferTo(localFile);
  

//调用AliyunOSSClientUtil的addPicture方法，fileName为key值,即上传文件在阿里云里oss里的名字，例如"OSSPicture/k.png"，localFile.getPath()为要上传文件本地的路径，path值
AliyunOSSClientUtil.addPicture(fileName,localFile.getPath());
map.put(“code”, 200);
map.put(“path”, “https://bucketName.oss-cn-beijing.aliyuncs.com/” + fileName);
}
} catch (Exception e) {
map.put(“code”, -2);
}
}

    return map;
}
