SpringBoot项目整合FastDFS+Nginx实现图片上传功能

接下来我将为您详细讲解“SpringBoot项目整合FastDFS+Nginx实现图片上传功能”的完整攻略。

环境准备

在开始前，我们需要准备好以下环境：

• JDK 1.8
• Maven
• SpringBoot 2.x
• FastDFS 5.0.10
• Nginx 1.18.0
• Linux服务器

FastDFS安装配置

1. 安装必备工具

yum -y install wget
yum -y install gcc
yum -y install gcc-c++
yum -y install make
yum -y install unzip

1. 下载并安装FastDFS

wget https://github.com/happyfish100/fastdfs/archive/V5.0.10.tar.gz
tar zxvf V5.0.10.tar.gz
cd fastdfs-5.0.10
./make.sh
./make.sh install

1. 安装Tracker服务

```bash
cp /etc/fdfs/tracker.conf.sample /etc/fdfs/tracker.conf
vi /etc/fdfs/tracker.conf

修改配置

tracker_server=192.168.1.1:22122

cp /etc/init.d/fdfs_trackerd /etc/init.d/
chmod +x /etc/init.d/fdfs_trackerd
chkconfig --add fdfs_trackerd
chkconfig fdfs_trackerd on
service fdfs_trackerd start

4. 安装Storage服务

```bash
cp /etc/fdfs/storage.conf.sample /etc/fdfs/storage.conf
vi /etc/fdfs/storage.conf

# 修改配置
tracker_server=192.168.1.1:22122
store_path0=/home/fastdfs/storage
group_name=group1

cp /etc/init.d/fdfs_storaged /etc/init.d/
chmod +x /etc/init.d/fdfs_storaged
chkconfig --add fdfs_storaged
chkconfig fdfs_storaged on
service fdfs_storaged start

至此，FastDFS的安装与配置已经完成。

Nginx安装配置

1. 安装Nginx

yum -y install nginx

1. 配置Nginx

cp /usr/local/fastdfs/conf/http.conf /etc/fdfs/
cp /usr/local/fastdfs/conf/mime.types /etc/fdfs/

vi /etc/fdfs/http.conf

# 修改配置
url_have_group_name = true

cp /usr/local/nginx/conf/nginx.conf /usr/local/nginx/conf/nginx.conf.bak
vi /usr/local/nginx/conf/nginx.conf

# 修改配置
location ~/group([0-9])/ {
    # 改为自己的 FastDFS Storage IP 地址
    proxy_pass http://192.168.1.2:8888;
}

service nginx start

SpringBoot整合FastDFS+Nginx

1. 添加FastDFS客户端依赖

<dependency>
    <groupId>org.csource</groupId>
    <artifactId>fastdfs-client-java</artifactId>
    <version>1.29-SNAPSHOT</version>
</dependency>

1. 配置文件

# FastDFS配置
fastdfs.connect_timeout_in_seconds=5
fastdfs.network_timeout_in_seconds=30
fastdfs.charset=UTF-8
fastdfs.http_anti_steal_token=false
fastdfs.http_secret_key=FastDFS1234567890
fastdfs.http_tracker_http_port=8080
fastdfs.tracker_servers=192.168.1.1:22122

1. 上传文件代码

import java.io.IOException;

import org.csource.common.MyException;
import org.csource.fastdfs.ClientGlobal;
import org.csource.fastdfs.StorageClient1;
import org.springframework.web.multipart.MultipartFile;

@Component
public class FastDFSUtil {
    private static StorageClient1 storageClient = null;

    static {
        try {
            ClientGlobal.initByProperties("fastdfs-client.properties");
            storageClient = new StorageClient1();
        } catch (IOException | MyException e) {
            e.printStackTrace();
        }
    }

    public String upload(MultipartFile multipartFile) {
        try {
            byte[] fileBytes = multipartFile.getBytes();
            String fileExtName = FilenameUtils.getExtension(multipartFile.getOriginalFilename());
            String filePath = storageClient.upload_file1(fileBytes, fileExtName, null);
            return filePath;
        } catch (IOException | MyException e) {
            e.printStackTrace();
        }
        return null;
    }
}

1. 控制器代码

@RestController
public class FileUploadController {
    @Autowired
    private FastDFSUtil fastDFSUtil;

    @RequestMapping("/upload")
    public String upload(MultipartFile multipartFile) {
        String filePath = fastDFSUtil.upload(multipartFile);
        return filePath;
    }
}

至此，SpringBoot项目整合FastDFS+Nginx实现图片上传功能的攻略已经讲解完毕。

示例1

# 上传示例图片
curl -F 'file=@/path/to/image.jpg' http://localhost:8080/upload

示例2

@RestController
public class UserController {
    @Autowired
    private FastDFSUtil fastDFSUtil;

    @PostMapping("/user/{userId}/avatar")
    public String uploadAvatar(@PathVariable("userId") Long userId, MultipartFile multipartFile) {
        String filePath = fastDFSUtil.upload(multipartFile);
        // TODO 存储 filePath 到数据库
        return filePath;
    }
}

上面是一个用户头像上传的接口示例，具体的业务逻辑可以根据自己的需求进行实现。

希望以上内容对您有所帮助。
