La configuración de Spring Boot utiliza Alibaba Cloud OSS para realizar la carga de imágenes

Primero, maven build pom add

<dependency>
    <groupId>com.aliyun.oss</groupId>
    <artifactId>aliyun-sdk-oss</artifactId>
    <version>3.10.2</version>
</dependency>

application.yml configura algunos parámetros requeridos por oss

Escribir clase de herramienta OssUtils

import java.io.FileNotFoundException;
import java.io.InputStream;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

            return true;
        } catch (Exception e) {
            e.printStackTrace();

            putObjectForInputStream(file,content);
            return "http://"+bucketName+"."+endpoint+"/"+file;
        } catch (Exception e) {
            e.printStackTrace();

            return baos.toString("UTF-8");
        } catch (Exception e) {
            e.printStackTrace();
        }

    }


}

Método de implementación de la interfaz escriba una demostración aquí

@Resource
OssUtils imgUpload;

/**
     * 上传人脸图片
     */
    @PostMapping("uploadFaceData")
    @ResponseBody
    public ResultBody uploadFaceData(MultipartFile file) {
        // 1.获取上传文件输入流
        InputStream inputStream = null;
        try {
            inputStream = file.getInputStream();
        } catch (Exception e) {
            return ResultBody.error(ErrorEnum.ADDHOTEL_PARAMS_ERROR);
        }

        String url= imgUpload.putObjectForImage("test.jpg",inputStream,false);

        return ResultBody.success(url);
    }

Si tiene éxito, puede guardar la URL y usarla para recuperar recursos de imagen e imprimir la consola para depurar.
