【FastDFS】06 SpringBoot实现上传

创建SpringBoot工程：

再导入所需要的依赖：

        <dependency>
            <groupId>net.oschina.zcx7878</groupId>
            <artifactId>fastdfs-client-java</artifactId>
            <version>1.27.0.0</version>
        </dependency>

        <dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-lang3</artifactId>
        </dependency>

创建上传业务层程序：

package cn.dzz.fastdfs.service;

import org.apache.commons.lang3.StringUtils;
import org.csource.fastdfs.*;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
import org.springframework.web.multipart.MultipartFile;

import java.util.HashMap;
import java.util.Map;

/**
 * @author DaiZhiZhou
 * @file Boot-With-FastDFS
 * @create 2020-08-13 8:55
 */

// @PropertySource()
@Component
public class UploadService {

    @Value("${fastdfs.tracker_servers}")
    private String tracker_servers;

    @Value("${fastdfs.connect_timeout_in_seconds}")
    private int connect_timeout;

    @Value("${fastdfs.network_timeout_in_seconds}")
    private int network_timeout;

    @Value("${fastdfs.charset}")
    private String charset;

    public Map<String,Object> upload(MultipartFile multipartFile) {
        if (multipartFile == null) {
            throw new RuntimeException("文件不能为空");
        }
        // 上传至fastDFS, 返回文件id
        String fileId = this.fdfsUpload(multipartFile);
        if (StringUtils.isEmpty(fileId)) {
            System.out.println("上传失败");
            throw  new RuntimeException("上传失败");
        }
        Map<String, Object> map=new HashMap<>();
        map.put("code",200);
        map.put("msg","上传成功");
        map.put("fileId",fileId);
        return map;
    }

    /**
     * 上传至fastDFS
     * @param multipartFile
     * @return 文件id
     */
    private String fdfsUpload(MultipartFile multipartFile) {
        // 1. 初始化fastDFS的环境
        initFdfsConfig();
        // 2. 获取trackerClient服务
        TrackerClient trackerClient = new TrackerClient();
        try {
            TrackerServer trackerServer = trackerClient.getConnection();
            // 3. 获取storage服务
            StorageServer storeStorage = trackerClient.getStoreStorage(trackerServer);
            // 4. 获取storageClient
            StorageClient1 storageClient1 = new StorageClient1(trackerServer, storeStorage);
            // 5. 上传文件 (文件字节, 文件扩展名, )
            // 5.1 获取文件扩展名
            String originalFilename = multipartFile.getOriginalFilename();
            String extName = originalFilename.substring(originalFilename.lastIndexOf(".") + 1);
            // 5.2 上传
            String fileId = storageClient1.upload_file1(multipartFile.getBytes(), extName, null);
            return fileId;
        } catch (Exception e) {
            System.out.println(e);
            return null;
        }
    }

    /**
     * 初始化fastDFS的环境
     */
    private void initFdfsConfig() {
        try {
            ClientGlobal.initByTrackers(tracker_servers);
            ClientGlobal.setG_connect_timeout(connect_timeout);
            ClientGlobal.setG_network_timeout(network_timeout);
            ClientGlobal.setG_charset(charset);
        } catch (Exception e) {
            System.out.println(e);
        }
    }
}

创建上传控制器：

package cn.dzz.fastdfs.controller;

import cn.dzz.fastdfs.service.UploadService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.multipart.MultipartFile;

import java.util.Map;

/**
 * @author DaiZhiZhou
 * @file Boot-With-FastDFS
 * @create 2020-08-13 8:58
 */

@RestController
@RequestMapping("upload")
public class UploadController {

    @Autowired
    private UploadService uploadService;

    /**
     * 作上传
     */
    @RequestMapping("doUpload")
    public Map<String,Object> doUpload(MultipartFile mf){
        System.out.println(mf.getOriginalFilename());
        Map<String, Object> map = uploadService.upload(mf);
        return map;
    }
}

在static目录中创建index.html用于上传测试：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>

<h1>文件上传</h1>
<hr>
<form action="/upload/doUpload" method="post" enctype="multipart/form-data">
    <input type="file" name="mf">
    <input type="submit" value="上传">
</form>

</body>
</html>

运行SpringBoot进行测试：

上传文件实现方式二：

更改依赖：

        <!-- https://mvnrepository.com/artifact/com.github.tobato/fastdfs-client -->
        <dependency>
            <groupId>com.github.tobato</groupId>
            <artifactId>fastdfs-client</artifactId>
            <version>1.26.7</version>
        </dependency>

创建一个配置类UploadProperties

package cn.dzz.fastdfs.config;

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

import java.util.List;

/**
 * @author DaiZhiZhou
 * @file Boot-With-FastDFS
 * @create 2020-08-13 9:10
 */

@Data
@Component
@ConfigurationProperties(prefix = "upload")
public class UploadProperties {
    private String baseUrl;
    private List<String> allowTypes;
}

更改之前的yml配置：

fdfs:
  so-timeout: 2500       # 读取时间
  connect-timeout: 600   # 连接超时时间
  thumb-image:           # 缩略图
    width: 100
    height: 100
  tracker-list:          # tracker服务配置地址列表
    - 服务器或者虚拟机IP:22122
upload:
  base-url: http://服务器或者虚拟机IP/
  allow-types:
    - image/jpeg
    - image/png
    - image/bmp
    - image/gif

编写UploadProperties.java

package cn.dzz.config;

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;

import java.util.List;

/**
 * @author DaiZhiZhou
 * @file fdfs
 * @create 2020-08-13 9:33
 */
@ConfigurationProperties(prefix = "upload")
@Data
public class UploadProperties {
    private String baseUrl;
    private List<String> allowTypes;
}

业务层：

package cn.dzz.service;

import cn.dzz.config.UploadProperties;
import com.github.tobato.fastdfs.domain.fdfs.StorePath;
import com.github.tobato.fastdfs.service.FastFileStorageClient;
import org.apache.commons.lang3.StringUtils;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.stereotype.Component;
import org.springframework.web.multipart.MultipartFile;

import javax.imageio.ImageIO;
import java.awt.image.BufferedImage;
import java.io.IOException;

/**
 * @author DaiZhiZhou
 * @file fdfs
 * @create 2020-08-13 9:34
 */

@Component
@EnableConfigurationProperties(UploadProperties.class)
public class UploadService {
    private Log log= LogFactory.getLog(UploadService.class);

    @Autowired
    private FastFileStorageClient storageClient;

    @Autowired
    private UploadProperties prop;

    public String uploadImage(MultipartFile file) {
        // 1、校验文件类型
        String contentType = file.getContentType();
        if (!prop.getAllowTypes().contains(contentType)) {
            throw new RuntimeException("文件类型不支持");
        }
        // 2、校验文件内容
        try {
            BufferedImage image = ImageIO.read(file.getInputStream());
            if (image == null || image.getWidth() == 0 || image.getHeight() == 0) {
                throw new RuntimeException("上传文件有问题");
            }
        } catch (IOException e) {
            log.error("校验文件内容失败....{}", e);
            throw new RuntimeException("校验文件内容失败"+e.getMessage());
        }

        try {
            // 3、上传到FastDFS
            // 3.1、获取扩展名
            String extension = StringUtils.substringAfterLast(file.getOriginalFilename(), ".");
            // 3.2、上传
            StorePath storePath = storageClient.uploadFile(file.getInputStream(), file.getSize(), extension, null);
            // 返回路径
            return prop.getBaseUrl() + storePath.getFullPath();
        } catch (IOException e) {
            log.error("【文件上传】上传文件失败！....{}", e);
            throw  new RuntimeException("【文件上传】上传文件失败！"+e.getMessage());
        }
    }
}

控制器：

package cn.dzz.controller;

import cn.dzz.service.UploadService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;

import java.util.HashMap;
import java.util.Map;

/**
 * @author DaiZhiZhou
 * @file fdfs
 * @create 2020-08-13 9:35
 */
@RequestMapping("upload")
@RestController
public class UploadController {

    @Autowired
    private UploadService uploadService;

    @RequestMapping("doUpload")
    public Map<String,Object> doUpload(MultipartFile multipartFile) {
        System.out.println(multipartFile.getOriginalFilename());
        Map<String, Object> map = new HashMap<>();
        String filePath = uploadService.uploadImage(multipartFile);
        map.put("filePath", filePath);
        return map;
    }

}

还是一样的上传页面：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>

<h1>文件上传</h1>
<hr>
<form action="/upload/doUpload" method="post" enctype="multipart/form-data">
    <input type="file" name="mf">
    <input type="submit" value="上传">
</form>

</body>
</html>

运行发现空指针异常，检查发现表单名称没对上，SpringMVC就无法转换了

<input type="file" name="multipartFile">
