Spring Boot入门样例-521-upload-aliyun-oss整合阿里云OSS上传图片

图片通过阿里云等云存储系统，可以让用户更快的显示图片。本demo演示如何演示如何将图片上传到阿里云OSS。

前言

本Spring Boot入门样例准备工作参考：

• Spring Boot入门样例-001-Java和Maven安装配置
• Spring Boot入门样例-003-idea 安装配置和插件
• Spring Boot入门样例-005-如何运行

pox.xml

必要的依赖如下，具体参见该项目的pox.xml

        
            org.springframework.boot

配置文件

resources/application.yml配置内容

aliyun:
  oss:
    address: http://static.sxxx.com
    end-point: oss-cn-shenzhen.aliyuncs.com
    access-key: LTAxxxxxxxxxxxxxx
    secret-key: z80tbxx
    bucket: funsonli-mini

代码解析

AliyunOssUtil.java 如下

@Slf4j
@Component
public class AliyunOssUtil {

    /** oss处访问图片的 url */
    @Value("${aliyun.oss.address}")
    private String address;

    /** oss的 endpoint */
    @Value("${aliyun.oss.end-point}")
    private String endPoint;

    @Value("${aliyun.oss.access-key}")
    private String accessKey;

    @Value("${aliyun.oss.secret-key}")
    private String secretKey;

    /** oss的储存名称 */
    @Value("${aliyun.oss.bucket}")
    private String bucket;

    /**
     * 文件流上传
     * @param file 文件名
     * @param key  文件名
     * @return
     */
    public String uploadInputStream(InputStream file, String key) {

        OSSClient ossClient = new OSSClient(endPoint, new DefaultCredentialProvider(accessKey, secretKey), null);
        try {
            ossClient.putObject(bucket, key, file);
            ossClient.shutdown();
            return address + "/" + key;
        } catch (Exception ex) {
            throw new RuntimeException("上传文件出错，请检查配置" + ex.toString());
        }
    }

    /**
     * 以UUID重命名
     *
     * @param fileName
     * @return
     */
    public String rename(String fileName) {
        String extName = fileName.substring(fileName.lastIndexOf("."));
        return UUID.randomUUID().toString().replace("-", "") + extName;
    }
}

CommonController.java 如下 upload直接上传文件

@Slf4j
@RestController
@RequestMapping("/bootan/common")
public class CommonController {
    @Autowired
    private AliyunOssUtil aliyunOssUtil;

    @RequestMapping(value = "/upload",method = RequestMethod.POST)
    public BaseResult upload(@RequestParam(required = false) MultipartFile file,
                             HttpServletRequest request) {

        String result = null;
        String fileName = aliyunOssUtil.rename(file.getOriginalFilename());
        try {
            InputStream inputStream = file.getInputStream();
            result = aliyunOssUtil.uploadInputStream(inputStream, fileName);
        } catch (Exception e) {
            log.error(e.toString());
            return BaseResult.error(e.toString());
        }

        return BaseResult.success(result);
    }

}
