上传图片到liunx系统，需要哪些配置？

上传资源到Linux上 步骤
需要：

1. 添加相应的依赖（需要下载并放到maven仓库中，否则pom.xml中下载不了）
2. 添加配置文件 client.conf和picurl.properties
3. 工具类 FastDFSClient

1、首先 先在pom文件 添加相应的依赖

<dependency>
            <groupId>org.csource</groupId>
            <artifactId>fastdfs-client-java</artifactId>
            <version>1.27-SNAPSHOT</version>
     </dependency>

因为fastdfs-client-java-1.27-SNAPSHOT.jar这个依赖包在maven中央仓库是没有的。
需要自己编译源码成jar本地安装到maven 的本地仓库，安装完以后就能正常引用了（注意：本地必须安装了Maven，并配置好Maven环境变量）

2、client.conf文件

tracker_server=172.20.10.10:22122
172.20.10.10是本机ip

picurl.properties文件

user.picurl=http://172.20.10.10

util工具类

package cn.hp.util;

import org.csource.common.NameValuePair;
import org.csource.fastdfs.ClientGlobal;
import org.csource.fastdfs.StorageClient1;
import org.csource.fastdfs.StorageServer;
import org.csource.fastdfs.TrackerClient;
import org.csource.fastdfs.TrackerServer;

public class FastDFSClient {

    private TrackerClient trackerClient = null;
    private TrackerServer trackerServer = null;
    private StorageServer storageServer = null;
    private StorageClient1 storageClient = null;

    public FastDFSClient(String conf) throws Exception {
        if (conf.contains("classpath:")) {
            conf = conf.replace("classpath:", this.getClass().getResource("/").getPath());
        }
        ClientGlobal.init(conf);
        trackerClient = new TrackerClient();
        trackerServer = trackerClient.getConnection();
        storageServer = null;
        storageClient = new StorageClient1(trackerServer, storageServer);
    }

    /**
     * 上传文件方法
     * <p>Title: uploadFile</p>
     * <p>Description: </p>
     * @param fileName 文件全路径
     * @param extName 文件扩展名，不包含（.）
     * @param metas 文件扩展信息
     * @return
     * @throws Exception
     */
    public String uploadFile(String fileName, String extName, NameValuePair[] metas) throws Exception {
        String result = storageClient.upload_file1(fileName, extName, metas);
        return result;
    }

    public String uploadFile(String fileName) throws Exception {
        return uploadFile(fileName, null, null);
    }

    public String uploadFile(String fileName, String extName) throws Exception {
        return uploadFile(fileName, extName, null);
    }

    /**
     * 上传文件方法
     * <p>Title: uploadFile</p>
     * <p>Description: </p>
     * @param fileContent 文件的内容，字节数组
     * @param extName 文件扩展名
     * @param metas 文件扩展信息
     * @return
     * @throws Exception
     */
    public String uploadFile(byte[] fileContent, String extName, NameValuePair[] metas) throws Exception {

        String result = storageClient.upload_file1(fileContent, extName, metas);
        return result;
    }

    public String uploadFile(byte[] fileContent) throws Exception {
        return uploadFile(fileContent, null, null);
    }

    public String uploadFile(byte[] fileContent, String extName) throws Exception {
        return uploadFile(fileContent, extName, null);
    }
}

controller层

package cn.hp.controller;

import cn.hp.util.FastDFSClient;
import cn.hp.util.Result;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.PropertySource;
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;



@PropertySource("classpath:picurl.properties")
@RestController
public class PictureController {

    @Value("${user.picurl}")
    private String IMAGE_SERVER_URL;

    @RequestMapping("/pic/upload")
    public Result picUpload(@RequestParam("imgFile") MultipartFile imgFile) {
        System.out.println("uploadFile =" + imgFile);
        try {
            //接收上传的文件
//        区扩展名
            String originaFilename = imgFile.getOriginalFilename();
            String extName = originaFilename.substring(originaFilename.lastIndexOf(".") + 1);
            //上传到图片服务器

            FastDFSClient fastDFSClient = new FastDFSClient("classpath:client.conf");
            String url=fastDFSClient.uploadFile(imgFile.getBytes(),extName);
            url = IMAGE_SERVER_URL + "/" + url;
//            相应上传图片的url
            System.out.println("url =" + url);
            return new Result().success(url);


        } catch (Exception e) {
            e.printStackTrace();
            return new Result().error("400","服务器异常");
        }



    }
}
