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() {
b790

}

/**
* 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。

package com.cdy.utils;

import java.io.File;
import java.io.IOException;
import java.io.InputStream;
import java.util.Date;

import com.aliyun.oss.ClientException;
import com.aliyun.oss.OSSClient;
import com.aliyun.oss.OSSException;
import com.aliyun.oss.model.GetObjectRequest;
import com.aliyun.oss.model.OSSObject;
import com.aliyun.oss.model.ObjectMetadata;

/**
* 对OSS服务器进行上传删除等的处理
*
* @ClassName: OSSManageUtil
* @Description:
* @author liux
* @date 2017-5-3 上午10:47:00
*
*/
public class OSSManageUtil {
/**
* 上传OSS服务器文件 @Title: uploadFile
* @param multipartFile spring 上传的文件
* remotePath @param oss服务器二级目录
* @throws Exception 设定文件 @return String
* 返回类型 @throws
*/
public static String uploadFile(InputStream fileContent, String remotePath,String fileName) throws Exception {
//随机名处理
fileName = "lxkc_" + new Date().getTime() + fileName.substring(fileName.lastIndexOf("."));
// 加载配置文件，初始化OSSClient
OSSConfigure ossConfigure = new OSSConfigure("/system.properties");
OSSClient ossClient = new OSSClient(ossConfigure.getEndpoint(), ossConfigure.getAccessKeyId(),
ossConfigure.getAccessKeySecret());
// 定义二级目录
String remoteFilePath = remotePath.substring(0, remotePath.length()).replaceAll("\\\\", "/") + "/";
// 创建上传Object的Metadata
ObjectMetadata objectMetadata = new ObjectMetadata();
objectMetadata.setContentLength(fileContent.available());
objectMetadata.setContentEncoding("utf-8");
objectMetadata.setCacheControl("no-cache");
objectMetadata.setHeader("Pragma", "no-cache");
objectMetadata.setContentType(contentType(fileName.substring(fileName.lastIndexOf("."))));
objectMetadata.setContentDisposition("inline;filename=" + fileName);
// 上传文件
ossClient.putObject(ossConfigure.getBucketName(), remoteFilePath + fileName, fileContent, objectMetadata);
// 关闭OSSClient
ossClient.shutdown();
// 关闭io流
fileContent.close();
return ossConfigure.getAccessUrl() + "/" + remoteFilePath + fileName;
}

// 下载文件
@SuppressWarnings("unused")
public static void downloadFile(OSSConfigure ossConfigure, String key, String filename)
throws OSSException, ClientException, IOException {
// 初始化OSSClient
OSSClient ossClient = new OSSClient(ossConfigure.getEndpoint(), ossConfigure.getAccessKeyId(),
ossConfigure.getAccessKeySecret());
OSSObject object = ossClient.getObject(ossConfigure.getBucketName(), key);
// 获取ObjectMeta
ObjectMetadata meta = object.getObjectMetadata();

// 获取Object的输入流
InputStream objectContent = object.getObjectContent();

ObjectMetadata objectData = ossClient.getObject(new GetObjectRequest(ossConfigure.getBucketName(), key),
new File(filename));
// 关闭数据流
objectContent.close();

}

/**
* 根据key删除OSS服务器上的文件 @Title: deleteFile @Description: @param @param
* ossConfigure @param @param filePath 设定文件 @return void 返回类型 @throws
* @throws IOException
*/
public static void deleteFile( String filePath) throws IOException {
// 加载配置文件，初始化OSSClient
OSSConfigure ossConfigure = new OSSConfigure("/system.properties");
OSSClient ossClient = new OSSClient(ossConfigure.getEndpoint(), ossConfigure.getAccessKeyId(),
ossConfigure.getAccessKeySecret());
filePath=filePath.substring(45);
ossClient.deleteObject(ossConfigure.getBucketName(), filePath);

}

/**
* Description: 判断OSS服务文件上传时文件的contentType @Version1.0
*
* @param FilenameExtension
* 文件后缀
* @return String
*/
public static String contentType(String FilenameExtension) {
if (FilenameExtension.equals(".BMP") || FilenameExtension.equals(".bmp")) {
return "image/bmp";
}
if (FilenameExtension.equals(".GIF") || FilenameExtension.equals(".gif")) {
return "image/gif";
}
if (FilenameExtension.equals(".JPEG") || FilenameExtension.equals(".jpeg") || FilenameExtension.equals(".JPG")
|| FilenameExtension.equals(".jpg") || FilenameExtension.equals(".PNG")
|| FilenameExtension.equals(".png")) {
return "image/jpeg";
}
if (FilenameExtension.equals(".HTML") || FilenameExtension.equals(".html")) {
return "text/html";
}
if (FilenameExtension.equals(".TXT") || FilenameExtension.equals(".txt")) {
return "text/plain";
}
if (FilenameExtension.equals(".VSD") || FilenameExtension.equals(".vsd")) {
return "application/vnd.visio";
}
if (FilenameExtension.equals(".PPTX") || FilenameExtension.equals(".pptx") || FilenameExtension.equals(".PPT")
|| FilenameExtension.equals(".ppt")) {
return "application/vnd.ms-powerpoint";
}
if (FilenameExtension.equals(".DOCX") || FilenameExtension.equals(".docx") || FilenameExtension.equals(".DOC")
|| FilenameExtension.equals(".doc")) {
return "application/msword";
}
if (FilenameExtension.equals(".XML") || FilenameExtension.equals(".xml")) {
return "text/xml";
}
if (FilenameExtension.equals(".apk") || FilenameExtension.equals(".APK")) {
return "application/octet-stream";
}
return "text/html";
}
}

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)
@ResponseBody
public 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！
