oss的简单使用（已实现图片、视频的成功上传）

需要导入的dependency

后两个依赖主要是用于实现Bucket的创建以及文件的上传

       <dependency>
            <groupId>com.aliyun.oss</groupId>
            <artifactId>aliyun-sdk-oss</artifactId>
            <version>3.10.2</version>
        </dependency>
        <dependency>
            <groupId>commons-io</groupId>
            <artifactId>commons-io</artifactId>
            <version>1.3.2</version>
        </dependency>
        <dependency>
            <groupId>commons-fileupload</groupId>
            <artifactId>commons-fileupload</artifactId>
            <version>1.2.1</version>
        </dependency>

 

加载完相关依赖后，便可以通过创建OSSClient对象调用相关接口实现相关功能啦.

注意：在没有绑定私有域名的情况下，文件上传成功后返回的url只能是下载链接...

代码如下： 1 package com.aliyun.oss;

import com.aliyun.oss.model.CannedAccessControlList;
import com.aliyun.oss.model.CreateBucketRequest;
import com.aliyun.oss.model.MultipartUpload;
import org.springframework.util.StreamUtils;
import org.springframework.util.StringUtils;
import org.springframework.web.multipart.MultipartFile;

import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.UUID;

public class OssUtil {
    //定义外网访问的参数 --地域节点
    private static String EndPoint = "oss-cn-zhangjiakou.aliyuncs.com";
    private  static String AccessKeyID = "XXXXXXX";
    private static String AccessKeySecret = "XXXXXXX";
    private static String BucketName = "tiandankanfeng"; //仓库名称
    private static String SufferUrl = "http://tiandankanfeng.oss-cn-zhangjiakou.aliyuncs.com/"; //文件上传成功后返回的路径，类似二级域名
    private static SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd"); //格式化时间

    public OSSClient getOSSClient(){
        //创建一个OSSClient对象
        OSSClient ossClient = new OSSClient(EndPoint,AccessKeyID,AccessKeySecret);
        if(ossClient.doesBucketExist(BucketName)) {
            System.out.println("success");
            //关闭oss的连接 此处不要关闭，后面会调用，不然会报错
        }else { //通过api接口来创建bucket
            System.out.println("fail to find ,so to get a new one");
            //创建一个oss仓库
            CreateBucketRequest bucketRequest = new CreateBucketRequest(null);
            bucketRequest.setBucketName(BucketName);
            bucketRequest.setCannedACL(CannedAccessControlList.PublicRead); //设置访问权限 --公共读
            ossClient.createBucket(bucketRequest); //映射原理，会重新生成一个ossClient并覆盖当前的ossClient

        }
        return ossClient;
    }

    /**
     * 上传文件
     * @param multipartFile  需要上传的文件
     * @param fileType  文件类型
     * @return
     */
    public String uploadDocuments(MultipartFile multipartFile, String fileType) throws IOException {
        //获取oss连接
        OSSClient ossClient = this.getOSSClient();
        //获取文件的后缀名称
        String ext = multipartFile.getOriginalFilename().substring(multipartFile.getOriginalFilename().lastIndexOf("."));
        String fileName = getFileName(fileType, ext);
        String url = null;
        //通过ossclient获取上传文件后返回的url
        ossClient.putObject(BucketName,fileName,new ByteArrayInputStream(multipartFile.getBytes()));
        url = SufferUrl+fileName;
        System.out.println("------>>上传文件成功，url："+url);
　　　　　ossClient.shutdown();

        return url;

    }

    private String getFileName(String fileType, String ext) {
        //上传至oss的那个文件夹 通过filename来指定 生成规则 // www.liangye123.com/img/20200814/jdg.png
        String date = sdf.format(new Date());
        if(StringUtils.isEmpty(fileType)){
            fileType = "default";
        }
        //为了避免图片重名，使用UUID来命名图片
        String uuid = UUID.randomUUID().toString().replace("-","");
        //组合filename
        String filename = fileType+"/"+date+"/"+uuid+ext;
        return filename;
    }

    public static void main(String[] args) {
        OssUtil ou = new OssUtil();
        ou.getOSSClient();
    }
}

 

测试类：

package com.aliyun.oss;

import org.junit.jupiter.api.Test;
import org.springframework.mock.web.MockMultipartFile;
import org.springframework.web.multipart.MultipartFile;

import java.io.File;
import java.io.FileInputStream;

import static org.junit.jupiter.api.Assertions.*;

class OssUtilTest {

    @Test
    void getOSSClient() {
    }

    @Test
    void uploadDocuments() throws Exception{
        assert(true);
        File file = new File("H:/desktop/个人image/个人image/宽图/a2c1f-wemjb.jpg");
        FileInputStream in_file= new FileInputStream(file);
        //File与MutipartFile的转化
        MultipartFile multipartFile = new MockMultipartFile("a2c1f-wemjb.jpg","a2c1f-wemjb.jpg","jpeg",in_file);
        String url = new OssUtil().uploadDocuments(multipartFile,"jpg");
    }
}

 

测试结果：

啊，图片应该不违规吧 QAQ
