Minio文件上传

文件上传

一，本地上传

/** * @description:最基础的上传 * @author: Teao * @date: 2022/7/8 0:19 * @param: [formData] * @return: com.wangshidai.springboot002.entity.R **/
@PostMapping("/uploadImg")
public R upload(MultipartFile formData) throws IOException {
    
    log.info("开始处理文件上传，文件名是{}",formData.getOriginalFilename()); // 打印日志
    // 取到上传的文件的后缀名
    String filename = formData.getOriginalFilename();
    String s = filename.substring(filename.indexOf("."));
    
    formData.transferTo(new File(("d:\\"+UUID.randomUUID()+s)));// 将UUID.randomUUID()+s随机文件名 文件传到本地服务器去
    return new R(200,"上传成功",UUID.randomUUID()+s);
}

二，Minio上传

1.导入依赖

<!--minio-->
<dependency>
    <groupId>io.minio</groupId>
    <artifactId>minio</artifactId>
    <version>8.0.3</version>
</dependency>

2.配置application.yml文件

# minio 参数配置
minio:
  endpoint: http://192.168.80.188:9090 # minio 服务地址
  accessKey: minioadmin # minio Access key就像用户ID，可以唯一标识你的账户
  secretKey: minioadmin # minio Secret key是你账户的密码
  bucketName: teao-test # minio 桶名称

3.添加配置文件（MinIoClientConfig）

@Configuration
public class MinIoClientConfig {
    

    @Value("${minio.endpoint}")
    private String endpoint;
    @Value("${minio.accessKey}")
    private String accessKey;
    @Value("${minio.secretKey}")
    private String secretKey;

    /** * 注入minio 客户端 * @return */
    @Bean
    public MinioClient minioClient(){
    

        return MinioClient.builder()
                .endpoint(endpoint)
                .credentials(accessKey, secretKey)
                .build();
    }
}

4.使用

@Value("${minio.bucketName}")
private String bucketName;

@Resource
private MinioClient minioClient;

/** * @description:Minio上传 * @author: Teao * @date: 2022/7/8 8:14 * @param: [formData] * @return: com.wangshidai.springboot002.entity.R **/
@PostMapping("/uploadImg")
public R upload(MultipartFile formData) throws IOException {
    
    log.info("开始处理文件上传，文件名是{}",formData.getOriginalFilename());
    
    // 生成上传随机的文件名
    String filename = formData.getOriginalFilename();
    String s = filename.substring(filename.indexOf("."));
    filename = UUID.randomUUID()+s;
    
    try {
    
        PutObjectArgs objectArgs = PutObjectArgs.builder().object(filename)
                .bucket(bucketName)
                .contentType(formData.getContentType())
                .stream(formData.getInputStream(),formData.getSize(),-1).build();

        minioClient.putObject(objectArgs);  // 需要注入进来 @Resource private MinioClient minioClient;
        // 拼接将要返回的字符串
        String url = "http://60.205.214.35:9090/wangshidai-test/"+filename;
        return new R(200,"上传成功",url);
    } catch (Exception e) {
    
        e.printStackTrace();
        return new R(500,"上传失败",null);
    }
}
