网上关于minio分片上传的资料不太详细，缺斤少两，所以我基于他们的代码做了一些修改，demo能够正常运行起来，但是偶尔也会发生一些小bug，不过这些都无伤大雅，最终目的是理解代码背后的逻辑和流程
流程：
- 前端获取生成文件MD5，发送至后台判断是否有该文件缓存，有信息终止上传，无则开始进行文件分片 。这里，我为了简单方便实现便没有使用数据库，直接用redis存储文件信息；
- 前端后端返回的结果进行分片，然后将文件分片的信息传输给后端，后端调用 minio 初始化，返回分片上传地址和 uploadId；
- 前端则根据获取的分片上传地址直接通过axios上传分片文件，不走后端；
- 上传完成后，前端发送请求至后端，后端调用 minio 合并文件；
流程图：
效果图
1.vue前端
2. minio文件桶
一.前端vue代码（代码较多，我就分开贴）
项目中使用到的类库：spark-md5、axios、element-ui；
spark-md5 主要用来计算文件MD5，安装命令：
npm install spark-md5 --S1.template

9.FileUploadInfo，还有最重要的实体类
package com.xy.entity;
import lombok.Data;
import lombok.experimental.Accessors;
@Data
@Accessors(chain = true)
public class FileUploadInfo {
//@NotBlank(message = "文件名不能为空")
private String fileName;
// @NotNull(message = "文件大小不能为空")
private Double fileSize;
// @NotBlank(message = "Content-Type不能为空")
private String contentType;
// @NotNull(message = "分片数量不能为空")
private Integer partCount;
// @NotBlank(message = "uploadId 不能为空")
private String uploadId;
// 桶名称
//private String bucketName;
//md5
private String fileMd5;
//文件类型
private String fileType;
public FileUploadInfo() {
}
}
10.RedisRepo
package com.xy.util;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.BoundValueOperations;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.stereotype.Component;
import java.util.concurrent.TimeUnit;
@Component
public class RedisRepo {
@Autowired
private StringRedisTemplate redisTemplate;
public String get(String key) {
BoundValueOperations<String, String> ops = redisTemplate.boundValueOps(key);
return ops.get();
}
public void save(String key,String str){
BoundValueOperations<String, String> ops = redisTemplate.boundValueOps(key);
ops.set(str);
}
public void saveTimeout(String key, String value, long timeout, TimeUnit unit ){
redisTemplate.boundValueOps(key).setIfAbsent(value,timeout,unit);
}
public void delete(String key){
redisTemplate.delete(key);
}
public long expire(String key){
return redisTemplate.opsForValue().getOperations().getExpire(key);
}
}
