FastDFS图片服务器java后台的简单调用

工具类：

package com.liveyc.common.fdfs;


import org.apache.commons.io.FilenameUtils;
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;
import org.springframework.core.io.ClassPathResource;

public class FastDFSUtils {
    
    /**

     * @date:   2017年12月14日  
     * @param pic 图片二进制

     * @return
     */
    public static String uploadPic(byte[] pic ,String name,long size){
        String path = null;
        //ClientGloble 读配置文件
        ClassPathResource resource = new ClassPathResource("fdfs_client.conf");
        try {
            ClientGlobal.init(resource.getClassLoader().getResource("fdfs_client.conf").getPath());
            //老大客户端
            TrackerClient trackerClient = new TrackerClient();
            TrackerServer trackerServer = trackerClient.getConnection();
            StorageServer storageServer  = null;
            StorageClient1 storageClient1 = new StorageClient1(trackerServer, storageServer);
            //图片11.jpg  根据图片名称得到图片后缀    jpg
            String ext = FilenameUtils.getExtension(name);
            
            NameValuePair[] meta_list = new NameValuePair[3];
            meta_list[0] = new NameValuePair("fileName",name);
            meta_list[1] = new NameValuePair("fileExt",ext);
            meta_list[2] = new NameValuePair("fileSize",String.valueOf(size));
            
            
            //  group1/M00/00/01/wKjIgFWOYc6APpjAAAD-qk29i78248.jpg
            path = storageClient1.upload_file1(pic, ext, meta_list);
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return path;
    }
}

service层代码：

package com.liveyc.core.service.product;



import org.springframework.stereotype.Service;

import com.liveyc.common.fdfs.FastDFSUtils;

@Service("uploadService")
public class UploadServiceImpl implements UploadService{

    
    //上传图片
    public String uploadPic(byte[] pic ,String name,long size){
        return FastDFSUtils.uploadPic(pic, name, size);
    }
}

Controller层代码

//图片服务器
public static final String IMG_URL = "http://172.16.71.221/";

        jo.put("url", url);

        response.getWriter().write(jo.toString());
        
    }
    
    //上传多张图片

    public @ResponseBody
    List<String> uploadPics(@RequestParam(required = false) MultipartFile[] pics

            String url = Constants.IMG_URL + path;
            urls.add(url);
        }
        return urls;
    }
    
}

Controller层

jsp：

 js

<script type="text/javascript">
//上传图片
function uploadPic(){
    //jquery.form.js
    var options = {
            url : "/upload/uploadPic.do",
            dataType : "json",
            type : "post",
            success : function(data){
                $("#allUrl").attr("src",data.url);
                $("#imgUrl").val(data.url);
            }
    }
    $("#jvForm").ajaxSubmit(options);
}
</script>

测试结果：

 点击 选择图片以后 会立即把图片上传至fastdfs服务器  同时返回一条url连接

 

将连接 可在浏览器直接打开
