项目原图
在这里插入图片描述 application.yml配置

server:
  port: 8888

fdfs:
  connect-timeout: 10000(设置连接超时时间)
  so-timeout: 3000(设置请求超时时间)
  tracker-list: #TrackerList参数,支持多个
    - 192.168.87.129:22122
spring:
  datasource:
    url: jdbc:mysql://localhost/unit02
    password: ps123456
    driver-class-name: com.mysql.jdbc.Driver
    username: root
http:
  multipart:
    max-file-size: 25698000(配置上传的最大字节数)

控制层

package cn.ps;
import com.luhuiguo.fastdfs.domain.StorePath;
import com.luhuiguo.fastdfs.service.FastFileStorageClient;
import org.apache.commons.io.FilenameUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.ColumnMapRowMapper;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.multipart.MultipartFile;

import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.net.URLEncoder;
import java.util.List;
import java.util.Map;

@RestController
public class UploadController {

 @Autowired
 protected FastFileStorageClient storageClient;

 @Autowired
 JdbcTemplate jdbcTemplate;

 /**
  *
  * @param myFile 从浏览器提交过来
  * @return
  * @throws IOException
  */
 @PostMapping("/fupload")
 public  String upload(@RequestParam("myFile")MultipartFile myFile) throws IOException {
     String extName= FilenameUtils.getExtension(myFile.getOriginalFilename());
     StorePath sp=storageClient.uploadFile("group1",myFile.getInputStream(),myFile.getSize(),extName);
     String sql="insert into  myfile(filename,groupname,fileipath) values(?,?,?)";
     jdbcTemplate.update(sql,myFile.getOriginalFilename(),sp.getGroup(),sp.getPath());
     return sp.getFullPath();
 }
 @GetMapping("/fdownload/{id}")
 public void  download(@PathVariable String id, HttpServletResponse response) throws IOException {
     List list =jdbcTemplate.query("select *from  myfile where fileid="+id,new ColumnMapRowMapper());

     Map map =(Map)list.get(0);
     String fileName= URLEncoder.encode(map.get("filename").toString(),"UTF-8");
     String groupName=map.get("groupname").toString();
     String fileiPath=map.get("fileipath").toString();

     //告诉浏览器 下载的文件名
     response.setHeader("Content-Disposition","attachment; filename="+fileName+"");
     //将文件的内容输出到浏览器中
    byte[] bt= storageClient.downloadFile(groupName,fileiPath);
    response.getOutputStream().write(bt);
 }

}

运行的main方法


package cn.ps;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class BootMain {
    public static void main(String[] args) {
        SpringApplication.run(BootMain.class);
    }
}

一个简单的上传文件页面

<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <form method="post" enctype="multipart/form-data" action="fupload">
        文件<input type="file" name="myFile"/>
        <input type="submit" value="上传"/>

    </form>
</body>
</html>

一个简单的下载文件页面

<!DOCTYPE html>
