Spring boot 集成 Minio 对象存储

简介

Minio支持接入JavaScript、Java、Python、Golang等多种语言，这里我们选择最熟悉的Java语言，使用最流行的框架 SpringBoot 2.x。

Spring boot 集成 Minio

添加pom依赖

<dependency>
    <groupId>com.jlefebure</groupId>
    <artifactId>spring-boot-starter-minio</artifactId>
    <version>1.1</version>
</dependency>

修改配置文件

minio:
   url: http://192.168.0.247:9000
   bucket: test
   access-key: minioadmin
   secret-key: minioadmin

测试接口类

@RestController
@RequestMapping("/files")
public class MinioController {

    @Autowired
    private MinioService minioService;

    @GetMapping("/list")
    public List<Item> testMinio() throws MinioException {
        return minioService.list();
    }

    @GetMapping("/{object}")
    public void getObject(@PathVariable("object") String object, HttpServletResponse response) throws MinioException, IOException {
        InputStream inputStream = minioService.get(Paths.get(object));

        response.addHeader("Content-disposition", "attachment;filename=" + object);
        response.setContentType(URLConnection.guessContentTypeFromName(object));
        IOUtils.copy(inputStream, response.getOutputStream());
        response.flushBuffer();
    }

    @PostMapping("/upload")
    public void addAttachement(@RequestParam("file") MultipartFile file) {
        Path path = Paths.get(file.getOriginalFilename());
        try {
            minioService.upload(path, file.getInputStream(), file.getContentType());
        } catch (MinioException e) {
            throw new IllegalStateException("The file cannot be upload on the internal storage. Please retry later", e);
        } catch (IOException e) {
            throw new IllegalStateException("The file cannot be read", e);
        }
    }
}
