一、fastdfs搭建

1.从git上下载 fastdfs-nginx

### thanks  gituser 545314690
git clone https://github.com/545314690/fastdfs-nginx.git

2. 修改Conf

storage.conf

###can not use 127.0.0.1
tracker_server=host-ip:22122

mod_fastdfs.conf

tracker_server=127.0.0.1:22122

nginx.conf

如果用redis记录的token，可以配置如下，没有此方面需求，自行忽略
## if need check token from redis 
upstream redisbackend {
  server    redis-server-ip:port;
  keepalive 1024;
}

[x] 启动 https（根据需求选择是否启动）

启用 https 当然要申请https证书，放置在容器中的/etc/cert/目录，阿里云免费证书申请方案请参考：https://www.jianshu.com/p/4f3bccd29bd9

如果启用https协议，请打开下面ssl 配置注释

### ssl 配置 start
# ssl on;
# ssl_certificate   /etc/cert/214927684720376.pem;
# ssl_certificate_key  /etc/cert/214927684720376.key;
# ssl_session_timeout 5m;
# ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
# ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
# ssl_prefer_server_ciphers on;
### ssl 配置 end

other conf files if you needed

3. Build 自己的docker镜像

 ## you can use your image name to replace name 'fastdfs-nginx'
docker build -t fastdfs-nginx .

4. 网络配置

根据需求配置，这里可以不配置，具体bridge和Overlay网络区别请参考：

https://www.cnblogs.com/atuotuo/p/6926390.html

## you can create your network for this server, like:
docker network create --driver bridge --subnet 192.168.1.108/20 network0

5.启动docker容器

第一种方式（测试通过）--建议采用

## should use host network (test pass)
docker run -itd \
  --name fastdfs-nginx \
  --network=host \
  -v /etc/localtime:/etc/localtime:ro \
  -v /var/log/fdfs/:/data/fdfs/logs/ \
  -v /data/fdfs/data/:/data/fdfs/data/ \
  -v /var/log/nginx/:/var/log/nginx/ \
  fastdfs-nginx \
  sh -c "/usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf restart && /usr/bin/fdfs_storaged /etc/fdfs/storage.conf restart && /usr/sbin/nginx -g 'daemon off;'"

第二种方式

## if you want to use your network and use ip 192.168.16.6
## in this case, you should update some conf to make fdfs work
## like set tracker_server in storage.conf to 192.168.16.6
## the app which use fdfs-client-java to upload file should in the same network (not test yet)
docker run -itd \
  --name fastdfs-nginx \
  --network=network0 --ip=192.168.16.6 \
  -p 22122:22122 \
  -p 23000:23000 \
  -p 24001:24001 \
  -p 24002:24002 \
  -p 11411:11411 \
  -v /etc/localtime:/etc/localtime:ro \
  -v /var/log/fdfs/:/data/fdfs/logs/ \
  -v /data/fdfs/data/:/data/fdfs/data/ \
  -v /var/log/nginx/:/var/log/nginx/ \
  fastdfs-nginx \
  sh -c "/usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf restart && /usr/bin/fdfs_storaged /etc/fdfs/storage.conf restart && /usr/sbin/nginx -g 'daemon off;'"

6.API测试

如果采用了token用下面url测试是否安装成功

## fetch file from server, if you need check token
http://ip:24001/group1/M00/00/00/xxxxxx?tk=zzz&&typ=yyy

如果无token用下面url测试是否安装成功

## fetch file from server directly
http://ip:24002/group1/M00/00/00/xxxxxx.yyy

二、fastdfs上传接口编写

1.引入maven

<!-- https://mvnrepository.com/artifact/com.github.tobato/fastdfs-client -->
        <dependency>
            <groupId>com.github.tobato</groupId>
            <artifactId>fastdfs-client</artifactId>
            <version>1.26.2</version>
        </dependency>

2.上传接口

package com.topcom.cms.spider.utils.fastdfs;

import com.github.tobato.fastdfs.FdfsClientConfig;
import com.github.tobato.fastdfs.domain.StorePath;
import com.github.tobato.fastdfs.exception.FdfsUnsupportStorePathException;
import com.github.tobato.fastdfs.service.FastFileStorageClient;
import org.apache.commons.io.FilenameUtils;
import org.apache.commons.lang3.StringUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.EnableMBeanExport;
import org.springframework.context.annotation.Import;
import org.springframework.jmx.support.RegistrationPolicy;
import org.springframework.mock.web.MockMultipartFile;
import org.springframework.web.multipart.MultipartFile;

import java.io.*;
import java.nio.charset.Charset;

/**
 * FastDFS文件上传下载包装类
 */
@Configuration
@Import(FdfsClientConfig.class)
// 解决jmx重复注册bean的问题
@EnableMBeanExport(registration = RegistrationPolicy.IGNORE_EXISTING)
public class FastDFSClientWrapper {

    private final Logger logger = LoggerFactory.getLogger(FastDFSClientWrapper.class);

    @Value("${fdfs.nginx-host}")
    private String nginxHost;

    @Autowired
    private FastFileStorageClient storageClient;

    /**
     * 上传文件
     *
     * @param file 文件对象
     * @return 文件访问地址
     * @throws IOException
     */
    public String uploadFile(MultipartFile file) throws IOException {
        StorePath storePath = storageClient.uploadFile(file.getInputStream(), file.getSize(),
                FilenameUtils.getExtension(file.getOriginalFilename()), null);
        return getResAccessUrl(storePath);
    }

    /**
     * 上传文件 File
     *
     * @param fileName 文件名
     * @return 文件访问地址
     * @throws IOException
     */
    public String uploadFile(String fileName) throws IOException {
        MultipartFile multipartFile = file2MultipartFile(fileName);
        if (null != multipartFile) {
            return uploadFile(multipartFile);
        }
        return null;
    }

    /**
     *根据文件名把file转化为MultipartFile
     * @param pathName
     * @return
     */
    public MultipartFile file2MultipartFile(String pathName) {
        File file = new File(pathName);
        try {
            FileInputStream inputStream = new FileInputStream(file);
            MultipartFile multipartFile = new MockMultipartFile(file.getName(), file.getName(), "", inputStream);
            return multipartFile;
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    }

    /**
     * 将一段字符串生成一个文件上传
     *
     * @param content       文件内容
     * @param fileExtension
     * @return
     */
    public String uploadFile(String content, String fileExtension) {
        byte[] buff = content.getBytes(Charset.forName("UTF-8"));
        ByteArrayInputStream stream = new ByteArrayInputStream(buff);
        StorePath storePath = storageClient.uploadFile(stream, buff.length, fileExtension, null);
        return getResAccessUrl(storePath);
    }

    // 封装图片完整URL地址
    private String getResAccessUrl(StorePath storePath) {
        String fileUrl = storePath.getFullPath();
        return nginxHost + '/' + fileUrl;
    }

    /**
     * 传图片并同时生成一个缩略图 "JPG", "JPEG", "PNG", "GIF", "BMP", "WBMP"
     *
     * @param file 文件对象
     * @return 文件访问地址
     * @throws IOException
     */
    public String uploadImageAndCrtThumbImage(MultipartFile file) throws IOException {
        StorePath storePath = storageClient.uploadImageAndCrtThumbImage(file.getInputStream(), file.getSize(),
                FilenameUtils.getExtension(file.getOriginalFilename()), null);
        return getResAccessUrl(storePath);
    }

    /**
     * 删除文件
     *
     * @param fileUrl 文件访问地址
     * @return
     */
    public void deleteFile(String fileUrl) {
        if (StringUtils.isEmpty(fileUrl)) {
            return;
        }
        try {
            StorePath storePath = StorePath.praseFromUrl(fileUrl);
            storageClient.deleteFile(storePath.getGroup(), storePath.getPath());
        } catch (FdfsUnsupportStorePathException e) {
            logger.warn(e.getMessage());
        }
    }
}

3.spring-boot配置文件修改

application.properties

##fastdfs
fdfs.tracker-list[0]=192.168.1.108:22122
fdfs.nginx-host=http://192.168.1.108:24002
#单个数据大小，不配置默认单个文件是1M，会报错
spring.servlet.multipart.max-file-size= 10Mb
#总数据大小
spring.servlet.multipart.max-request-size=100Mb
