java配置阿里云存储文件

1.maven导入依赖

        <dependency>
            <groupId>com.aliyun.oss</groupId>
            <artifactId>aliyun-sdk-oss</artifactId>
            <version>3.17.4</version>
        </dependency>

如果使用的是Java 9及以上的版本，则还需要添加JAXB相关依赖。添加JAXB相关依赖示例代码如下：

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

阿里云上传图片工具类

/**
 * 阿里云 OSS 工具类
 */
public class AliOSSUtil {

    private String endpoint = "https://oss-cn-hangzhou.aliyuncs.com";
    private String accessKeyId = "LTAI4GCH1vX6DKqJWxd6nEuW";
    private String accessKeySecret = "yBshYweHOpqDuhCArrVHwIiBKpyqSL";
    private String bucketName = "web-tlias";

    /**
     * 实现上传图片到OSS
     */
    public String upload(MultipartFile file) throws IOException {
        // 获取上传的文件的输入流
        InputStream inputStream = file.getInputStream();

        // 避免文件覆盖
        String originalFilename = file.getOriginalFilename();
        String fileName = UUID.randomUUID().toString() + originalFilename.substring(originalFilename.lastIndexOf("."));

        //上传文件到 OSS
        OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);
        ossClient.putObject(bucketName, fileName, inputStream);

        //文件访问路径
        String url = endpoint.split("//")[0] + "//" + bucketName + "." + endpoint.split("//")[1] + "/" + fileName;
        // 关闭ossClient
        ossClient.shutdown();
        return url;// 把上传到oss的路径返回
    }
}

 private String endpoint = "https://oss-cn-hangzhou.aliyuncs.com";

其中 endpoint 对应创建bucket的地域

阿里云创建对应的accessKey填写

 private String accessKeyId = "LTAI4GCH1vX6DKqJWxd6nEuW";
    private String accessKeySecret = "yBshYweHOpqDuhCArrVHwIiBKpyqSL";
