阿里云 oss服务器文件上传 java

前天做oss服务器文件上传，之前没了解过，做的过程中遇到许多问题，最终通过查阅相关资料解决了，特分享一下。

首先准备工作 必要的jar 

这里注意版本一致，不然就会报很多坑爹的错误。。

如果你断点调试在执行putObject方法时报错，99%的是jar包有问题。。

然后是配置文件

现在开通oss，都是免费开通的，包年9块钱。

这是几个必要的参数，既然做这个肯定 要知道的！这里就不多做解释了。

这里，首先需要我们创建一个OSS信息实体类，OSSConfigure.Java，用来读取配置文件的信息，封装成实体。

import java.io.IOException;import java.io.InputStream;import java.util.Properties;    /**   * oss相关参数实体   * @author liux   *2017/5/5   */public class OSSConfigure {        private String endpoint;      private String accessKeyId;      private String accessKeySecret;      private String bucketName;      private String accessUrl;        public OSSConfigure() {        }        /**      * 通过配置文件.properties文件获取，这几项内容。      *       * @param storageConfName      * @throws IOException      */      public OSSConfigure(String storageConfName) throws IOException {            Properties prop = new Properties();         InputStream is= super.getClass().getClassLoader().getResourceAsStream(storageConfName);        prop.load(is);            endpoint = prop.getProperty("Endpoint").trim();          accessKeyId = prop.getProperty("AccessKey").trim();          accessKeySecret = prop.getProperty("AccessKeySecret").trim();          bucketName = prop.getProperty("BucketName").trim();          accessUrl = prop.getProperty("accessUrl").trim();        }        public OSSConfigure(String endpoint, String accessKeyId,              String accessKeySecret, String bucketName, String accessUrl) {            this.endpoint = endpoint;          this.accessKeyId = accessKeyId;          this.accessKeySecret = accessKeySecret;          this.bucketName = bucketName;          this.accessUrl = accessUrl;      }        public String getEndpoint() {          return endpoint;      }        public void setEndpoint(String endpoint) {          this.endpoint = endpoint;      }        public String getAccessKeyId() {          return accessKeyId;      }        public void setAccessKeyId(String accessKeyId) {          this.accessKeyId = accessKeyId;      }        public String getAccessKeySecret() {          return accessKeySecret;      }        public void setAccessKeySecret(String accessKeySecret) {          this.accessKeySecret = accessKeySecret;      }        public String getBucketName() {          return bucketName;      }        public void setBucketName(String bucketName) {          this.bucketName = bucketName;      }        public String getAccessUrl() {          return accessUrl;      }        public void setAccessUrl(String accessUrl) {          this.accessUrl = accessUrl;      }    }  

然后就是创建一个OSS文件管理的OSSManageUtil工具类。oss文件存储实际上就是对Object的操作，只要写好路径，都会自动创建的，OSSClient是oss的核心，有兴趣的可以多研究下。我做这个 是要上传app，以及压缩图片后上传，contentType这个方法注意，我上传的是apk  所以要用这个类型application/octet-stream，之前因为这个找了半天错。

以上是主要代码，再贴一下我的controller，我这里是做的app文件上传

/** * app文件上传 * * @param imageFile * @param request * @return */@RequestMapping(value = "/uploadApp", method = RequestMethod.POST)@ResponseBodypublic ImportResponse uploadApp(@RequestParam("app") MultipartFile appFile, VersionUpgrade versionUpgrade) {if (versionUpgrade == null) {return ImportResponse.fail("上传失败！");}try { // 流转换 将MultipartFile转换为oss所需的InputStream CommonsMultipartFile cf = (CommonsMultipartFile) appFile; DiskFileItem fi = (DiskFileItem) cf.getFileItem(); InputStream fileContent = fi.getInputStream(); String fileName = fi.getName();String apkUrl = OSSManageUtil.uploadFile( fileContent, "xxapp",fileName);versionUpgrade.setApkUrl(apkUrl);versionUpgrade.setLoginUserVw(curUser);versionUpgradeManager.save(versionUpgrade);} catch (Exception e) {log.error("【app上传失败】 :", e);return ImportResponse.fail("上传失败！");}return ImportResponse.success("上传成功！");}

以上就是全部内容了，都是api里面有的，因为自己做的过程中出现很多问题，所以分享给大家！
