1 MinIO安装(Docker)
●在root目录下新建docker_minio文件夹
●在docker_minio文件夹下新建config文件夹,data文件夹
●在root目录下新建docker_compose文件夹,在docker_compose文件夹中添加docker-compose.yaml
services:minio:image: quay.io/minio/miniocontainer_name: minio_containerports:- "9000:9000" #api接口(内部访问)- "9001:9001" #控制台端口(外部界面)environment:TZ: Asia/Shanghai #时区上海MINIO_ROOT_USER: abc #管理后台用户名MINIO_ROOT_PASSWORD: abc #管理后台密码(最少8个字符)MINIO_COMPRESS: "off" #开启压缩(on开启,off关闭)MINIO_COMPRESS_EXTENSIONS: "" #扩展名 .pdf .doc为空,所有类型均压缩MINIO_COMPRESS_MIME_TYPES: "" #mine类型application/pdf为空,所有类型均压缩volumes:- "/root/docker_minio/data:/data" #映射当前目录下的打他目录至容器内/data目录- "/root/docker_minio/config:/root/.minio" #映射配置目录command: server --address ':9000' --console-address ':9001' /data #服务器地址是9000,服务器控制台地址是9001,数据储存在/data下privileged: truenetworks:- sunner_network●通过docker compose up -d命令执行docker-compose.yaml文件(必须在docker_compose文件夹目录下执行),然后系统会自动拉取minio镜像,创建并启动minio容器
●执行docker ps -a命令,出现下图,表示安装和启动minio成功
2 MinIO的使用
访问MinIO有2个端口,分别是9000端口和9001端口
9000端口是用于内部访问,比如用户通过SpringBoot接口间接访问MinIO
9001端口是用于外部访问,即通过浏览器访问
2.1 桶
MinIO所有的文件都保存在桶中,可以将桶理解为文件夹
2.1.1新建桶
2.1.2 上传文件
2.2 网页访问图片
2.2.1 复制访问链接
●将127.0.0.1修改为MinIO所在服务器地址
●去掉访问链接后半段(去掉.png之后的)
2.2.2 修改桶权限为public
2.2.3 访问图片
在浏览器的地址栏输入"访问链接"
3 SpringBoot集成MinIO
3.1 引入依赖
<dependency><groupId>io.minio</groupId><artifactId>minio</artifactId><version>8.5.9</version>
</dependency>3.2 application.yaml
minio:endpoint: http://123.123.123.123:9000 #minio所在服务器访问地址accessKey: abc #用户名secretKey: abc #密码3.3 MinIO配置类
java">@Component
@ConfigurationProperties(prefix = "minio")
public class MinioProp {private String endpoint;private String accessKey;private String secretKey;public String getEndpoint() {return endpoint;}public void setEndpoint(String endpoint) {this.endpoint = endpoint;}public String getAccessKey() {return accessKey;}public void setAccessKey(String accessKey) {this.accessKey = accessKey;}public String getSecretKey() {return secretKey;}public void setSecretKey(String secretKey) {this.secretKey = secretKey;}
}3.4 通过MinIO配置类创建MinioClient,并注册进SpringIOC容器
java">@Configuration //"配置类"注解
@MapperScan({"xyz.aboluo.minio.dao"}) //dao接口包扫描
//@EnableConfigurationProperties({Teacher.class})
public class MinioAutoConfiguration {@Autowiredprivate MinioProp minioProp;@Beanpublic MinioClient getMinioClient() {return MinioClient.builder().endpoint(minioProp.getEndpoint()).credentials(minioProp.getAccessKey(), minioProp.getSecretKey()).build();}@Beanpublic CorsFilter corsFilter() {UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();CorsConfiguration corsConfiguration = new CorsConfiguration();corsConfiguration.addAllowedOrigin("*"); // 1 设置访问源地址(允许任何地址访问)corsConfiguration.addAllowedHeader("*"); // 2 设置访问源请求头(允许任何请求头访问)corsConfiguration.addAllowedMethod("*"); // 3 设置访问源请求方法(允许任何方法(GET,POST等等)方法)source.registerCorsConfiguration("/**", corsConfiguration); // 4 对接口配置跨域设置return new CorsFilter(source);}
}3.5 Controller接口
java">@RestController
@RequestMapping("/minioFileHandle")
public class MinioController {private static final Logger LOGGER = LoggerFactory.getLogger(MinioController.class);@Autowiredprivate MinioClient minioClient;/*** 获取bucket列表** @return*/@RequestMapping("/bucketList.do")public Result bucketList() throws ServerException, InsufficientDataException, ErrorResponseException, IOException, NoSuchAlgorithmException, InvalidKeyException, InvalidResponseException, XmlParserException, InternalException {List<Map<String, String>> buckets = new ArrayList<>();for (Bucket bucket : minioClient.listBuckets()) {Map<String, String> returnBucket = new HashMap<>();returnBucket.put("bucketName", bucket.name());returnBucket.put("creationDateTime", bucket.creationDate().toString());buckets.add(returnBucket);}return Result.success(buckets);}/*** 查询bucket下的所有文件信息** @return*/@RequestMapping("/queryBucketFiles.do")public Result queryBucketFiles(@RequestParam String bucketName) throws ServerException, InsufficientDataException, ErrorResponseException, IOException, NoSuchAlgorithmException, InvalidKeyException, InvalidResponseException, XmlParserException, InternalException {//检查桶是否存在if (!minioClient.bucketExists(BucketExistsArgs.builder().bucket(bucketName).build())) {throw new SunnerRuntimeException(Result.ResultEnum.BUCKET_NOT_EXIST);}//遍历封装桶中的文件信息Iterator<io.minio.Result<Item>> iterator = minioClient.listObjects(ListObjectsArgs.builder().bucket(bucketName).build()).iterator();List<Object> items = new ArrayList<>();while (iterator.hasNext()) {Item item = iterator.next().get();items.add(JSON.parse(String.format("{'fileName':'%s','fileSize':'%s','lastModified':'%s'}", item.objectName(), item.size(), Date.from(item.lastModified().toInstant()))));}return Result.success(items);}/*** 文件下载** @return*/@RequestMapping("/download.do")public Result download(@RequestParam String bucketName, @RequestParam String fileName, HttpServletResponse response) throws ServerException, InsufficientDataException, ErrorResponseException, IOException, NoSuchAlgorithmException, InvalidKeyException, InvalidResponseException, XmlParserException, InternalException {response.setHeader("picture-upload-date-time", URLEncoder.encode("abccc", StandardCharsets.UTF_8));response.getOutputStream().write(minioClient.getObject(GetObjectArgs.builder().bucket(bucketName).object(fileName).build()).readAllBytes());return Result.returnVoid();}
}
