Springboot集成阿里云OSS

安装SDK

方式一：在Maven项目中加入依赖项（推荐）

<!-- https://mvnrepository.com/artifact/com.aliyun.oss/aliyun-sdk-oss -->
<dependency>
    <groupId>com.aliyun.oss</groupId>
    <artifactId>aliyun-sdk-oss</artifactId>
    <version>3.11.2</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.apache.httpcomponents/httpclient -->
<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5.13</version>
</dependency>

如果使用的是java9及以上的版本，则需要添加jaxb的相关依赖项

<!-- https://mvnrepository.com/artifact/javax.xml.bind/jaxb-api -->
<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.1</version>
</dependency>
<!-- https://mvnrepository.com/artifact/javax.activation/activation -->
<dependency>
    <groupId>javax.activation</groupId>
    <artifactId>activation</artifactId>
    <version>1.1.1</version>
</dependency>
<!-- no more than 2.3.3-->
<!-- https://mvnrepository.com/artifact/org.glassfish.jaxb/jaxb-runtime -->
<dependency>
    <groupId>org.glassfish.jaxb</groupId>
    <artifactId>jaxb-runtime</artifactId>
    <version>3.0.0</version>
</dependency>

方式二、在Eclipse项目中导入JAR包

1、下载Java SDK开发包

2、解压该开发包

3、将解压后文件夹中的文件 aliyun-sdk-oss-3.10.2.jar 以及 lib 文件夹下的所有的文件拷贝到您的项目中

4、在Eclipse中选择工程，右键选择Properties > Java Build Path > Add JARs

5、选中拷贝的所有JAR文件，导入到Libraries中

方式三、在IDEA项目中导入JAR包

1、下载Java SDK 开发包

2、解压该开发包

3、将解压后文件夹中的文件 aliyun-sdk-oss-3.10.2jar 以及 lib 文件夹下的所有JAR文件拷贝到您的项目中

4、在IDEA中选择您的工程，右键选择File > Project Structure > Modules > Dependencies > + > JARs or directories

5、选中拷贝所有的JAR文件，导入到Extemal Libraries中

oss-config配置文件

方式一、自定义oss-config.propertes文件

#\u963F\u91CC\u4E91\u8D26\u53F7
access_key_id=**
#\u79D8\u94A5
access_key_secret=**
#endpoint
end_point=http://oss-cn-beijing.aliyuncs.com
#bucket
bucket_name=**
#basePath
base_path=orange-erp
#innerEndPoint
inner_end_point=http://oss-cn-beijing-internal.aliyuncs.com
#publicEndPoint
public_end_point=http://dx-pub-test.oss-cn-beijing.aliyuncs.com
#apkFileUpload
apk_file_upload=http://test.oss.chengzibianli.com

方式二、在yml文件中增加配置文件

# 阿里云oss
oss:
  endpoint: http://oss-cn-beijing.aliyuncs.com
  accessKeyId: *
  accessKeySecret: *
  bucketName: *

编写OssConfig.java 文件

1、使用oss-config方式一配置文件：

import com.aliyun.oss.HttpMethod;
import com.aliyun.oss.OSSClient;
import com.aliyun.oss.common.auth.DefaultCredentialProvider;
import com.aliyun.oss.model.CannedAccessControlList;
import com.aliyun.oss.model.GeneratePresignedUrlRequest;
import lombok.Getter;
import org.apache.commons.lang3.StringUtils;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.stereotype.Component;

import java.net.URL;
import java.util.Date;

@Configuration
@PropertySource(value = "classpath:oss-config.properties")
@Getter
@Component
public class OssConfig {
    /**
     * 阿里云账号id
     */
    @Value("${access_key_id}")
    private String accessKeyId;
    /**
     * 阿里云账号密钥
     */
    @Value("${access_key_secret}")
    private String accessKeySecret;
    /**
     * 对象存储oss外网endpoint
     */
    @Value("${end_point}")
    private String endPoint;
    /**
     * 存储空间
     */
    @Value("${bucket_name}")
    private String bucketName;
    /**
     * 存储根目录
     */
    @Value("${base_path}")
    private String basePath;

    /**
     * 对象存储oss公共endpoint
     */
    @Value("${public_end_point}")
    private String publicEndPoint;
    /**
     * 对象存储oss内网endpoint
     */
    @Value("${inner_end_point}")
    private String innerEndPoint;
    /**
     * 阿里云OSS客户端
     */
    private OSSClient ossClient;
    /**
     * 阿里云OSS内网客户端
     */
    private OSSClient innerOssClient;

    /**
     * 阿里云OSS外网客户端
     */
    private OSSClient publicOssClient;

    public OSSClient getOssClient() {
        if (ossClient == null) {
            ossClient = new OSSClient(endPoint, new DefaultCredentialProvider(accessKeyId, accessKeySecret), null);
        }
        return ossClient;
    }

    public OSSClient getInnerOssClient() {
        if (innerOssClient == null) {
            innerOssClient = new OSSClient(innerEndPoint, new DefaultCredentialProvider(accessKeyId, accessKeySecret), null);
        }
        return innerOssClient;
    }

    public OSSClient getPublicOssClient() {
        if (publicOssClient == null) {
            publicOssClient = new OSSClient(endPoint, new DefaultCredentialProvider(accessKeyId, accessKeySecret), null);
        }
        return publicOssClient;
    }

    public String getPub(String key) {
        //设置单个key 为公共读
        this.publicOssClient.setObjectAcl(bucketName, StringUtils.removeStart(key, "/"), CannedAccessControlList.PublicRead);
        //返回路径
        return publicEndPoint + (StringUtils.startsWith(key, "/") ? key : "/" + key);
    }

    /**
     * 生成图片返显url
     *
     * @param picKey     图片key
     * @param expiration 过期时间
     * @return url
     */
    public String getPicUrl(String picKey, Date expiration) {
        GeneratePresignedUrlRequest req = new GeneratePresignedUrlRequest(bucketName, picKey, HttpMethod.GET);
        req.setExpiration(expiration);
        URL signedUrl = this.getOssClient().generatePresignedUrl(req);
        return signedUrl.toString();
    }

2、使用oss-config方式二配置文件：

import org.springframework.beans.factory.InitializingBean;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;

@Configuration
@ConfigurationProperties(prefix = "oss")
public class AliyunOssConfig implements InitializingBean {

    /**
     * 阿里云 oss 站点
     */
    private String endpoint;

    /**
     * 阿里云 oss 公钥
     */
    private String accessKeyId;

    /**
     * 阿里云 oss 私钥
     */
    private String accessKeySecret;

    /**
     * 阿里云 oss 文件根目录
     */
    private String bucketName;

    //文件最大上传大小
    public static long FILE_MAX_SIZE = 1024 * 1024 * 10l;

    //图片过期时间 100年
    public static long FILE_EXPIRATION_TIME = 1000 * 3600 * 24 * 365 * 100;

    public static String JAVA_END_POINT;
    public static String JAVA_ACCESS_KEY_ID;
    public static String JAVA_ACCESS_KEY_SECRET;
    public static String JAVA_BUCKET_NAME;

    @Override
    public void afterPropertiesSet() throws Exception {
        JAVA_END_POINT = endpoint;
        JAVA_ACCESS_KEY_ID = accessKeyId;
        JAVA_ACCESS_KEY_SECRET = accessKeySecret;
        JAVA_BUCKET_NAME = bucketName;
    }

    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;
    }
}

编写oss请求参数和返回结果集

请求参数：

import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;

import javax.validation.constraints.NotNull;
import java.io.Serializable;

import lombok.Data;

/** 主要是为了经过编码的文件上传 **/
@Data
@ApiModel
public class FileUploadParam implements Serializable {

    @NotNull(message = "文件名称不能为空")
    @ApiModelProperty(value = "文件名称")
    private String fileName;

    @NotNull(message = "文件类型不能为空")
    @ApiModelProperty(value = "文件类型")
    private String fileType;

    /**
     * 经过base64编码后的文件
     */
    @NotNull(message = "文件内容不能为空")
    @ApiModelProperty(value = "文件内容")
    private String data;
}

返回结果集：

import lombok.Data;

@Data
public class AliyunOssResult {

    /**
     * code：200长传成功
     * code: 400上传失败
     */
    private int code;

    /**
     * 上传成功的返回url
     */
    private String url;

    /**
     * 错误提示
     */
    private String errMsg;
}
