springboot与fastdfs文件服务的整合_yml文件中的fdfs配置

一、springboot与fastdfs文件服务的整合

1. 引入 redis 依赖包

<dependency>
    <groupId>com.github.tobato</groupId>
    <artifactId>fastdfs-client</artifactId>
    <version>1.26.7</version>
</dependency>

2.yml文件中配置fastdfs

##############################################################
#
#fastdfs的配置
#
fdfs:
  connect-timeout: 30    #连接超时实际
  so-timeout: 30         #读取超时实际
  tracker-list: 192.168.1.6:22122    #tracker服务所在的ip地址和端口号

3.实现springboot客户端代码实现
（1）创建service接口

import org.springframework.web.multipart.MultipartFile;

public interface FdfsService {

    public String upload(MultipartFile file, String fileExtName) throws Exception;
}

（2）创建service接口实现类

import com.github.tobato.fastdfs.domain.fdfs.StorePath;
import com.github.tobato.fastdfs.service.FastFileStorageClient;
import com.imooc.service.FdfsService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.web.multipart.MultipartFile;


@Service
public class FdfsServiceImpl implements FdfsService {

    @Autowired
    private FastFileStorageClient fastFileStorageClient;

    @Override
    public String upload(MultipartFile file, String fileExtName) throws Exception {

        StorePath storePath = fastFileStorageClient.uploadFile(file.getInputStream(),
                                                                    file.getSize(),
                                                                    fileExtName,
                                                                    null);
        String fullPath = storePath.getFullPath();
        return fullPath;
    }
}

（3）创建controller类

import com.imooc.service.FdfsService;
import org.apache.commons.lang3.StringUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.HashMap;
import java.util.Map;

@RestController
@RequestMapping("fdfs")
public class CenterUserController{

    @Autowired
    private FdfsService fdfsService;

    @PostMapping("/uploadFace")
    public Object uploadFace(
            @RequestParam String userId,
            MultipartFile file,
            HttpServletRequest request, HttpServletResponse response) throws Exception {

        Map<String, Object> result = new HashMap<>();
        // 开始文件上传
        if (file != null) {

            //1.获取文件名
            String fileName = file.getOriginalFilename();
            //2.判断文件名
            if (StringUtils.isNotBlank(fileName)) {

                //3重组文件名
                String fileNameArr[] = fileName.split("\\.");
                // 获取文件的后缀名
                String suffix = fileNameArr[fileNameArr.length - 1];
                if (!suffix.equalsIgnoreCase("png") &&
                        !suffix.equalsIgnoreCase("jpg") &&
                        !suffix.equalsIgnoreCase("jpeg") ) {
                    return result.put("msg","图片格式不正确！");
                }
                String fullPath = fdfsService.upload(file, suffix);
                System.out.println(fullPath);

            }else {
                return result.put("msg","文件不能为空");
            }
        }
     
        return result.put("msg","success");
    }

}

（4）测试
a.需要写一段html来上传图片，这里就不展示了。
b.上传成功后，会在控制台输出完整路径：test/M00/00/00/wKgBB18v1a6AB1gpAAFkK4jbFUs729.jpg
c.浏览器中访问：http://192.168.1.7:8888/test/M00/00/00/wKgBB18v1a6AB1gpAAFkK4jbFUs729.jpg
界面显示刚刚上传的图片。

二、第三方云存储解决方案

FastDFS仅仅适用于简单的，功能单一的分布式文件系统。对于功能复杂，数据多变的文件系统而言，FastDFS不仅运维成本高，并且开发复杂度也非常高。所以下面会介绍第三方云存储解决方案。
