腾讯对象云存储

存储成功：

一、引入pom

<dependency>
            <groupId>com.qcloud</groupId>
            <artifactId>cos_api</artifactId>
            <version>4.4</version>
            <exclusions>
                <exclusion>
                    <groupId>org.slf4j</groupId>
                    <artifactId>slf4j-log4j12</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

二、腾讯配置

三、代码

1、controller

/**
     * 上传文件
     */
    @PostMapping("/upload")
    @ResponseBody
    public R upload(@RequestParam("file") MultipartFile file) throws Exception {

        //上传文件
        String suffix = file.getOriginalFilename().substring(file.getOriginalFilename().lastIndexOf("."));
        String url = CloudFactory.build().uploadSuffix(file.getBytes(), suffix);

        System.out.println("url=" + url);
、、                             这里需要将地址保存到数据库
        return R.ok().put("url", url);
    }

工厂类

public class CloudFactory {
    
    public static CloudStorageService build(){
        //获取云存储配置信息
        CloudStorageConfig config = new CloudStorageConfig();
        config.setQcloudAppId(1256);
        config.setQcloudBucketName("ly");
        config.setQcloudDomain("https://ly8.cossh.myqcloud.com");
        config.setQcloudPrefix("");
        config.setQcloudRegion("sh");
        config.setQcloudSecretId("6RdXDerpa7PSFm3RpKZ");
        config.setQcloudSecretKey("7zd191cx2rUXLtCFG3bu2va1DAs");
        
        return new QcloudCloudStorageService(config);
    }

构建配置

抽象类

/**
 * 云存储(支持七牛、阿里云、腾讯云、又拍云)
 * @author    lyon
 * @date    2018年3月27日
 */
public abstract class CloudStorageService {
     /** 云存储配置信息 */
    CloudStorageConfig config;

    /**
     * 文件路径
     * @param prefix 前缀
     * @param suffix 后缀
     * @return 返回上传路径
     */
    public String getPath(String prefix, String suffix) {
        //生成uuid
        String uuid = UUID.randomUUID().toString().replaceAll("-", "");
        //文件路径
        String path = DateUtils.format(new Date(), "yyyyMMdd") + "/" + uuid;

        if(StringUtils.isNotBlank(prefix)){
            path = prefix + "/" + path;
        }

        return path + suffix;
    }

    /**
     * 文件上传
     * @param data    文件字节数组
     * @param path    文件路径，包含文件名
     * @return        返回http地址
     */
    public abstract String upload(byte[] data, String path);

    /**
     * 文件上传
     * @param data     文件字节数组
     * @param suffix   后缀
     * @return         返回http地址
     */
    public abstract String uploadSuffix(byte[] data, String suffix);

    /**
     * 文件上传
     * @param inputStream   字节流
     * @param path          文件路径，包含文件名
     * @return              返回http地址
     */
    public abstract String upload(InputStream inputStream, String path);

    /**
     * 文件上传
     * @param inputStream  字节流
     * @param suffix       后缀
     * @return             返回http地址
     */
    public abstract String uploadSuffix(InputStream inputStream, String suffix);
}

配置类bean

public class CloudStorageConfig {
    
    //腾讯云绑定的域名
    private String qcloudDomain;
    //腾讯云路径前缀
    private String qcloudPrefix;
    //腾讯云AppId
    private Integer qcloudAppId;
    //腾讯云SecretId
    private String qcloudSecretId;
    //腾讯云SecretKey
    private String qcloudSecretKey;
    //腾讯云BucketName
    private String qcloudBucketName;
    //腾讯云COS所属地区
    private String qcloudRegion;

实际实现类

public class QcloudCloudStorageService extends CloudStorageService {
   
    private COSClient client;

    public QcloudCloudStorageService(CloudStorageConfig config){
        this.config = config;

        //初始化
        init();
    }

    private void init(){
        Credentials credentials = new Credentials(config.getQcloudAppId(), config.getQcloudSecretId(),
                config.getQcloudSecretKey());
        
        //初始化客户端配置
        ClientConfig clientConfig = new ClientConfig();
        //设置bucket所在的区域，华南：gz 华北：tj 华东：sh
        clientConfig.setRegion(config.getQcloudRegion());
        
        client = new COSClient(clientConfig, credentials);
    }

    @Override
    public String upload(byte[] data, String path) {
        //腾讯云必需要以"/"开头
        if(!path.startsWith("/")) {
            path = "/" + path;
        }
        
        //上传到腾讯云
        UploadFileRequest request = new UploadFileRequest(config.getQcloudBucketName(), path, data);
        String response = client.uploadFile(request);

        JSONObject jsonObject = JSONObject.fromObject(response);
        if(jsonObject.getInt("code") != 0) {
            try {
                throw new Exception("文件上传失败，" + jsonObject.getString("message"));
            } catch (Exception e) {
                e.printStackTrace();
            }
        }

        return config.getQcloudDomain() + path;
    }

    @Override
    public String upload(InputStream inputStream, String path) {
        try {
            byte[] data = IOUtils.toByteArray(inputStream);
            return this.upload(data, path);
        } catch (IOException e) {
            try {
                throw new Exception("上传文件失败", e);
            } catch (Exception e1) {
                e1.printStackTrace();
                return null;
            }
        }
    }

    @Override
    public String uploadSuffix(byte[] data, String suffix) {
        return upload(data, getPath(config.getQcloudPrefix(), suffix));
    }

    @Override
    public String uploadSuffix(InputStream inputStream, String suffix) {
        return upload(inputStream, getPath(config.getQcloudPrefix(), suffix));
    }
}
