整理一下minio后端使用篇，主要步骤如下：

• 1.引入Jar包，gradle方式：

compile 'io.minio:minio:5.0.2'

• 编写service bean

   1 @Service
   2 @Slf4j
   3 public class MinioService {
   4 
   5     private MinioClient minioClient;
   6 
   7     private MimetypesFileTypeMap mimetypesFileTypeMap;
   8 
   9   
  10     @Value("${minio.address}")
  11     private String address;
  12 
  13     @Value("${minio.accessKey}")
  14     private String accessKey;
  15 
  16     @Value("${minio.secretKey}")
  17     private String secretKey;
  18 
  19     public String getContentType(String fileName) {
  20         if (mimetypesFileTypeMap == null) {
  21             mimetypesFileTypeMap = new MimetypesFileTypeMap();
  22         }
  23         return mimetypesFileTypeMap.getContentType(fileName);
  24     }
  25     @PostConstruct
  26     private void init() throws Exception {
  27         minioClient = new MinioClient(address, accessKey, secretKey);
  28     }
  29 
  30     public MinioClient getMinioClient() {
  31         return this.minioClient;
  32     }
  33     public String getContentType(String fileName) {
  34         if (mimetypesFileTypeMap == null) {
  35             mimetypesFileTypeMap = new MimetypesFileTypeMap();
  36         }
  37         return mimetypesFileTypeMap.getContentType(fileName);
  38     }
  39 
  40     public MinioFile getBucketFromUrl(String url) {
  41         String[] split = url.split("/");
  42         if (split.length < 3) {
  43             throw new RuntimeException("getBucketFromUrl: url " + url + " format is incorrect");
  44         }
  45         StringBuilder stringBuilder = new StringBuilder();
  46         for (int i = 2; i < split.length; i++) {
  47             stringBuilder.append(split[i]);
  48             if (i != split.length - 1) {
  49                 stringBuilder.append("/");
  50             }
  51         }
  52         String fileName = stringBuilder.toString();
  53         return new MinioFile(split[1], fileName);
  54     }
  55 
  56 }
