苍穹外卖--实现照片上传

1 定义OSS相关配置

在sky-server模块
application-dev.yml

sky:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    host: localhost
    port: 3306
    database: sky_take_out
    username: root
    password: 1234

  alioss:
    endpoint: oss-cn-beijing.aliyuncs.com
    access-key-secret: Ociu2oAVv5FyAHpjL3LMNPiuhWqeDt
    access-key-id: LTAI5tPQSXovXyuYMLQcenb7
    bucket-name: spring-boot-web-study

application.yml

spring:
  profiles:

sky:
  alioss:
    endpoint: ${sky.alioss.endpoint}
    access-key-id: ${sky.alioss.access-key-id}
    access-key-secret: ${sky.alioss.access-key-secret}
    bucket-name: ${sky.alioss.bucket-name}

2读取OSS配置

在sky-common模块中，已定义

package com.sky.properties;

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Component
@ConfigurationProperties(prefix = "sky.alioss")
@Data
public class AliOssProperties {

    private String endpoint;
    private String accessKeyId;
    private String accessKeySecret;
    private String bucketName;

}

3生成OSS工具类对象

在sky-server模块

/**
 * 配置类，用于创建AliOssUtil对象
 */
@Configuration
@Slf4j
public class OssConfiguration {

    @Bean
    @ConditionalOnMissingBean
    public AliOssUtil aliOssUtil(AliOssProperties aliOssProperties){
        log.info("开始创建阿里云文件上传工具类对象：{}",aliOssProperties);
        return new AliOssUtil(aliOssProperties.getEndpoint(),
                aliOssProperties.getAccessKeyId(),
                aliOssProperties.getAccessKeySecret(),
                aliOssProperties.getBucketName());
    }
}

# 4定义文件上传接口：

```cpp

/**
 * 通用接口
 */
@RestController
@RequestMapping("/admin/common")
@Api(tags = "通用接口")
@Slf4j
public class CommonController {

    @Autowired
    private AliOssUtil aliOssUtil;

    /**
     * 文件上传
     * @param file
     * @return
     */
    @PostMapping("/upload")
    @ApiOperation("文件上传")
    public Result upload(MultipartFile file){
        log.info("文件上传：{}",file);

        try {
            //原始文件名
            String originalFilename = file.getOriginalFilename();
            //截取原始文件名的后缀   dfdfdf.png
            String extension = originalFilename.substring(originalFilename.lastIndexOf("."));
            //构造新文件名称
            String objectName = UUID.randomUUID().toString() + extension;

            //文件的请求路径
            String filePath = aliOssUtil.upload(file.getBytes(), objectName);
            return Result.success(filePath);
        } catch (IOException e) {
            log.error("文件上传失败：{}", e);
        }

        return Result.error(MessageConstant.UPLOAD_FAILED);
    }
}
