1、在nacos中配置minio参数

 2、controller层

package com.heima.wemedia.controller.v1;import com.heima.model.common.dtos.ResponseResult;
import com.heima.wemedia.service.WmMaterialService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;@RestController
@RequestMapping("/api/v1/material")
public class WmMaterialController {@AutowiredWmMaterialService wmMaterialService;@PostMapping("/upload_picture")public ResponseResult upload(MultipartFile multipartFile){return wmMaterialService.upload(multipartFile);}}

3、接口实现类

     封装minio上传工具Minio： 封装MinIO为starter_moreCalm的博客-CSDN博客

     获取用户id的前置工作 微服务：从header中获取用户存入当前线程_moreCalm的博客-CSDN博客
