拿来即用：SpringBoot+Minio+vue-uploader实现分片上传

以下是一个简化的Spring Boot和MinIO结合使用进行分片上传的例子。

Spring Boot 控制器 (UploadController.java):

import io.minio.MinioClient;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.multipart.MultipartFile;
 
@RestController
public class UploadController {
 
    private final MinioClient minioClient;
 
    public UploadController(MinioClient minioClient) {
        this.minioClient = minioClient;
    }
 
    @PostMapping("/upload")
    public String uploadFile(@RequestParam("file") MultipartFile file) {
        try {
            minioClient.putObject("my-bucket", file.getOriginalFilename(), file.getInputStream(), file.getContentType());
            return "File uploaded successfully";
        } catch (Exception e) {
            e.printStackTrace();
            return "Failed to upload file";
        }
    }
}

MinIO 客户端配置 (MinioConfig.java):

import io.minio.MinioClient;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
 
@Configuration
public class MinioConfig {
 
    @Bean
    public MinioClient minioClient() {
        try {
            return MinioClient.builder()
                    .endpoint("http://127.0.0.1:9000")
                    .credentials("minioadmin", "minioadmin")
                    .build();
        } catch (Exception e) {
            e.printStackTrace();
            throw new RuntimeException("Error while creating MinioClient", e);
        }
    }
}

前端 Vue.js 使用 vue-upload-component 实现分片上传:

<template>
  <file-upload
    ref="upload"
    v-model="files"
    :post-action="postAction"
    :put-action="putAction"
    :put-headers="putHeaders"
  ></file-upload>
</template>
 
<script>
import FileUpload from 'vue-upload-component'
 
export default {
  components: {
    FileUpload
  },
  data() {
    return {
      files: [],
      postAction: '/upload',
      putAction: 'http://127.0.0.1:9000/my-bucket',
      putHeaders: {
        Authorization: 'Bearer ' + this.getToken()
      }
    }
  },
  methods: {
    getToken() {
      // 获取MinIO的Token或者通过其他方式进行认证
      return 'your-minio-token';
    }
  }
}
</script>

确保你已经在项目中包含了MinIO的依赖和相关配置，并且MinIO服务器正在运行。这个例子假设你已经有了一个运行中的Spring Boot应用和一个MinIO服务器。

注意: 实际应用中你需要对上传的文件进行验证和权限控制，并处理可能出现的异常。这里为了简化，直接将其省略。
