加入自动配置
在resources中新建META-INF/spring.factories
org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
xyz.qianchen.file.service.impl.MinIOFileStorageService
使用步骤
-
导入qianchen-file-stater的依赖
-
在微服务中添加相关的配置信息
minio: accessKey: minio secretKey: minio bucket: images endpoint: http://192.168.200.130:9000 readPath: http://192.168.200.130:9000 -
注入service
@Autowired private FileStorageService fileStorageService;
