1、Java 项目开发中阿里云 oss 上传本地到服务器以及下载功能实现及配置 一pom.xml 中配置：com.aliyun aliyun-java-sdk-core 2.1.9com.aliyun.oss aliyun-sdk-oss 2.0.5com.aliyun.opensearch aliyun-sdk-opensearch 2.1.3com.aliyun aliyun-java-sdk-ecs 2.0.0-rc2com.aliyun aliyun-java-sdk-cms 2.0.0二创建 aliyunoss.properties：文件内容：需要根据自己申请的账号进行配置，这里我用 x
2、xx 代替 #ACCESS_ID ACCESS_ID=xxx #ACCESS_KEY ACCESS_KEY=xxx #OSS_ENDPOINT OSS_ENDPOINT=xxx #bucketName bucketName=xxx 三创建 AliyunOssConfig.java 读取配置文件信息: package com.zxm.cmds.aliyun;import java.util.Properties;import mons.logging.Log; import mons.logging.LogFactory;/* 加载oss配置* * author Administrator*/
3、public class AliyunOssConfig public static String ACCESS_ID = “; public static String ACCESS_KEY = “; public static String OSS_ENDPOINT = “; public static String bucketName = “; static Log log = LogFactory.getLog(AliyunOssConfig.class);public static void load() log.info(“oss配置加载开始 .“); Properties pr
4、op = new Properties(); try prop.load(AliyunOssConfig.class.getResourceAsStream(“/config/aliyunoss.properties“); ACCESS_ID = prop.getProperty(“ACCESS_ID“); ACCESS_KEY = prop.getProperty(“ACCESS_KEY“);OSS_ENDPOINT = prop.getProperty(OSS_ENDPOINT); bucketName = prop.getProperty(“bucketName“); catch (Ex
5、ception e) log.error(“oss配置加载失败“); /* return the aCCESS_ID*/ public static String getACCESS_ID() return ACCESS_ID; /* param aCCESS_ID* the aCCESS_ID to set*/ public static void setACCESS_ID(String aCCESS_ID) ACCESS_ID = aCCESS_ID; /* return the aCCESS_KEY*/ public static String getACCESS_KEY() retur
6、n ACCESS_KEY; /* param aCCESS_KEY* the aCCESS_KEY to set*/ public static void setACCESS_KEY(String aCCESS_KEY) ACCESS_KEY = aCCESS_KEY; /* return the oSS_ENDPOINT*/ public static String getOSS_ENDPOINT() return OSS_ENDPOINT; /* param oSS_ENDPOINT* the oSS_ENDPOINT to set*/ public static void setOSS_
7、ENDPOINT(String oSS_ENDPOINT) OSS_ENDPOINT = oSS_ENDPOINT; /* return the bucketName*/ public static String getBucketName() return bucketName; /* param bucketName* the bucketName to set*/ public static void setBucketName(String bucketName) AliyunOssConfig.bucketName = bucketName; 四创建 AliyunOssUtil.ja
8、va 接口实现 package com.zxm.cmds.aliyun;import java.io.File; import java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.InputStream; import java.util.List;import mons.logging.Log; import mons.logging.LogFactory; import com.aliyun.oss.ClientException; import com.aliyun.oss.OSSCl
9、ient; import com.aliyun.oss.OSSException; import com.aliyun.oss.model.CannedAccessControlList; import com.aliyun.oss.model.GetObjectRequest; import com.aliyun.oss.model.OSSObjectSummary; import com.aliyun.oss.model.ObjectListing; import com.aliyun.oss.model.ObjectMetadata;public class AliyunOssUtil
10、static Log log = LogFactory.getLog(AliyunOssUtil.class);public static void save(String key,String filePath) try / 使用默认的OSS服务器地址创建OSSClient对象OSSClient client = new OSSClient(AliyunOssConfig.OSS_ENDPOINT,AliyunOssConfig.ACCESS_ ID,AliyunOssConfig.ACCESS_KEY);ensureBucket(client, AliyunOssConfig.bucket
11、Name);setBucketPublicReadable(client, AliyunOssConfig.bucketName);System.out.println(“正在上传.“); / fileName = System.currentTimeMillis() + “.“ +getExtensionName(fileName);uploadFile(client, AliyunOssConfig.bucketName, key, filePath); catch(Exception e) log.error(“上传失败“); / 如果Bucket不存在，则创建它。private sta
12、tic void ensureBucket(OSSClient client, String bucketName)throws OSSException, ClientExceptionif (client.isBucketExist(bucketName)log.error(“isBucketExist true“);return;/创建bucketclient.createBucket(bucketName);/ 删除一个Bucket和其中的Objects private static void deleteBucket(OSSClient client, String bucketNa
13、me)throws OSSException, ClientException ObjectListing ObjectListing = client.listObjects(bucketName);List listDeletes = ObjectListing.getObjectSummaries();for (int i = 0; i listDeletes.size(); i+) String objectName = listDeletes.get(i).getKey();/ 如果不为空，先删除bucket下的文件client.deleteObject(bucketName, ob

15、olList.PublicRead);/ 上传文件private static void uploadFile(OSSClient client, String bucketName, String Objectkey, String filePath)throws OSSException, ClientException, FileNotFoundException File file = new File(filePath);ObjectMetadata objectMeta = new ObjectMetadata();objectMeta.setContentLength(file.length();/ 可以在metadata中标记文件类型if (filePath.endsWith(“xml“) objectMeta.setContentType(“text/xml“);else if (filePath.endsWith(“jpg“) objectMeta.setContentType(“image/jpeg“);else if (filePath.endsWith(“png“) objectMeta.setContentType(“image/png“);InputStream in
