一：pom添加以来jar
<dependency>
<groupId>com.aliyun.oss</groupId>
<artifactId>aliyun-sdk-oss</artifactId>
<version>2.8.3</version>
</dependency>
当然，也能下载jar导入项目；
二：关于文件上传的参数配置
新建 properties文件
三：在业务逻辑层获取阿里云对象
1：先获取属性文件
final static String endpoint = OssUtil.getConfig("contract"); final static String accessKeyId = OssUtil.getConfig("accessKeyIdContract"); final static String accessKeySecret = OssUtil.getConfig("accessKeySecretContract"); final static String bucketName = OssUtil.getConfig("bucketName4C");
2:属性文件的读取方法；
public class OssUtil { protected static Logger logger = LogManager.getLogger(OssUtil.class); public static String getConfig(String key) { String value = ""; OssUtil propertiesUtil = new OssUtil(); InputStream in = null; Properties props = new Properties(); in = propertiesUtil.getClass().getResourceAsStream("/oss.properties"); try { props.load(in); } catch (IOException e) { e.printStackTrace(); logger.error("getConfig io error:", e); } finally { if (in != null) { try { in.close(); } catch (IOException e2) { e2.printStackTrace(); logger.error("close io error:", e2); } } } value = props.getProperty(key); logger.info("property info :" + key + ":" + value); System.out.println(value); return value; } }
四：判断你要上传的文件是不是存在
@Override public boolean existFileInOss(String fileName) { // TODO Auto-generated method stub // 创建OSSClient实例 OSSClient ossClient = new OSSClient(endpoint, accessKeyId, accessKeySecret); // Object是否存在 boolean found = ossClient.doesObjectExist(bucketName, fileName); // 关闭client ossClient.shutdown(); return found; }
五：上传方法
@Override public void uploadFile(MultipartFile file,String fileId) { //String fileName =file.getOriginalFilename(); // 创建OSSClient实例 OSSClient ossClient = new OSSClient(endpoint, accessKeyId, accessKeySecret); // 上传文件流 try { ossClient.putObject(bucketName, fileId, file.getInputStream()); } catch (OSSException e) { e.printStackTrace(); } catch (ClientException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } // 关闭client ossClient.shutdown(); }
六：获取文件访问地址
@Override public String getFileUrl(String fileId) { //服务器端生成url签名字串 OSSClient Server = new OSSClient(endpoint, accessKeyId, accessKeySecret); Date expiration = null; expiration = new Date(System.currentTimeMillis()+1800000); //logger.debug("请求的fileid: " + fileId); GeneratePresignedUrlRequest request = new GeneratePresignedUrlRequest(bucketName, fileId, HttpMethod.GET); //设置过期时间 request.setExpiration(expiration); // 生成URL签名(HTTP GET请求) URL signedUrl = Server.generatePresignedUrl(request); //logger.debug("oss文件url: " + signedUrl); return signedUrl.toString(); }
七：删除文件
// 删除文件 //ossClient.deleteObject(bucketName, "文件的全路径，如：cia/merged.pdf");
八：控制台接收文件，调用业务层
public @ResponseBody String Upload(HttpServletRequest request, HttpServletResponse response, BsPayBussiness bussinessm, @RequestParam("file") MultipartFile file) { }
欢迎大家一起说出自己的想法。
