具体可以参考七牛JAVA SDK的源码以及官网使用文档：

简单上传

import com.qiniu.util.Auth;
import java.io.IOException;
import com.qiniu.common.QiniuException;
import com.qiniu.http.Response;
import com.qiniu.storage.UploadManager;

public class UploadDemo {
  //设置好账号的ACCESS_KEY和SECRET_KEY
  String ACCESS_KEY = "Access_Key";
  String SECRET_KEY = "Secret_Key";
  //要上传的空间
  String bucketname = "Bucket_Name";
  //上传到七牛后保存的文件名
  String key = "my-java.png";
  //上传文件的路径
  String FilePath = "/.../...";

  //密钥配置
  Auth auth = Auth.create(ACCESS_KEY, SECRET_KEY);
  //创建上传对象
  UploadManager uploadManager = new UploadManager();

  //简单上传，使用默认策略，只需要设置上传的空间名就可以了
  public String getUpToken(){
      return auth.uploadToken(bucketname);
  }

  public void upload() throws IOException{
    try {
      //调用put方法上传
      Response res = uploadManager.put(FilePath, null, getUpToken());
      //打印返回的信息
      System.out.println(res.bodyString());

          // 请求失败时打印的异常的信息
          System.out.println(r.toString());

上传&预转持续化(以视频转码为例)

import com.qiniu.util.Auth;
import com.qiniu.util.StringMap;
import com.qiniu.util.UrlSafeBase64;

import java.io.IOException;

import com.qiniu.common.QiniuException;

import com.qiniu.storage.UploadManager;

public class UploadDemo {
  //设置好账号的ACCESS_KEY和SECRET_KEY
  String ACCESS_KEY = "Access_Key";
  String SECRET_KEY = "Secret_Key";
  //要上传的空间
  String bucketname = "Bucket_Name";
  //上传到七牛后保存的文件名
  String key = "my-java.png";
  //上传文件的路径
  String FilePath = "/.../...";

  //设置转码操作参数
  String fops = "avthumb/mp4/s/640x360/vb/1.25m";
  //设置转码的队列
  String pipeline = "yourpipelinename";

  //可以对转码后的文件进行使用saveas参数自定义命名，当然也可以不指定文件会默认命名并保存在当前空间。
  String urlbase64 = UrlSafeBase64.encodeToString("目标Bucket_Name:自定义文件key");

          .putNotEmpty("persistentOps", pfops)
          .putNotEmpty("persistentPipeline", pipeline), true);
  }

      }       
  }

  public static void main(String args[]) throws IOException{  
    new UploadDemo().upload();

}


注：上面的Demo只是针对视频转码，如果需要别的功能比如音视频切片、视频截图、视频拼接只需要修改下上面的fops后面的参数就可以了，
eg: fops = "vframe/jpg/offset/1/w/480/h/360/rotate/90"就表示视频截图了。
下面给出一些常见的数据处理功能，可以根据需要进行选择：
//------------------图片缩放-------------------
fops ="imageView/2/w/200/h/200";

//------------------视频转码-------------------
// fops ="avthumb/flv/vb/229k/vcodec/libx264/noDomain/1";

//------------------图片水印-------------------
String pictureurl = UrlSafeBase64.encodeToString("http://developer.qiniu.com/resource/logo-2.jpg");
fops = "watermark/1/image/" + pictureurl;

//------------------视频切片-------------------
fops = "avthumb/m3u8";
//切片与加密参数
fops = "avthumb/m3u8/vb/640k/hlsKey/MDEyMzQ1Njc4OTEyMzQ1Ng==/hlsKeyUrl/aHR0cDovLzd4bGVrYi5jb20yLnowLmdsYi5xaW5pdWNkbi5jb20vcWluaXV0ZXN0LmtleQ==";

//------------------文档转换-------------------
fops = "yifangyun_preview";

//------------------视频截图-------------------
fops = "vframe/jpg/offset/1/w/480/h/360/rotate/90";

//------------------视频拼接-------------------
//拼接视频片段时要保证所有源的画面长宽值一致
//除去作为数据处理对象的源文件以外，还可以指定最多5个源文件（即总计6个片段）
//所有源文件必须属于同一存储空间
//格式:avconcat/<Mode>/format/<Format>/<encodedUrl0>/<encodedUrl1>/<encodedUrl2>/...
String encodedUrl1 = UrlSafeBase64.encodeToString("http://7xl4c9.com1.z0.glb.clouddn.com/pingjie2.flv");
String encodedUrl2 = UrlSafeBase64.encodeToString("http://7xl4c9.com1.z0.glb.clouddn.com/pingjie3.avi");
fops = "avconcat/2/format/mp4/"+encodedUrl1+encodedUrl2;

//------------------多文件压缩-------------------
//可将若干七牛空间中的资源文件，在七牛服务端压缩后存储
//格式:mkzip/<mode>/url/<Base64EncodedURL>/alias/<Base64EncodedAlias>/url/<Base64EncodedURL>
String encodedfile1 = UrlSafeBase64.encodeToString("http://7xl4c9.com1.z0.glb.clouddn.com/photo1.jpg");
String encodedfile2 = UrlSafeBase64.encodeToString("http://7xl4c9.com1.z0.glb.clouddn.com/vedio1.mp4");
String encodedfile3 = UrlSafeBase64.encodeToString("http://7xl4c9.com1.z0.glb.clouddn.com/audio1.mp3");
fops = "mkzip/2/url/"+encodedfile1+"url/"+encodedfile2+"url/"+encodedfile3;

        String SECRET_KEY = "Secret_Key";
        Auth auth = Auth.create(ACCESS_KEY, SECRET_KEY);

        //实例化一个BucketManager对象
        BucketManager bucketManager = new BucketManager(auth);

        //要列举文件的空间名
        String bucket = "yourbucket";

        try {
          //调用listFiles方法列举指定空间的指定文件
          //参数一：bucket    空间名
          //参数二：prefix    文件名前缀
          //参数三：marker    上一次获取文件列表时返回的 marker
          //参数四：limit     每次迭代的长度限制，最大1000，推荐值 100
          //参数五：delimiter 指定目录分隔符，列出所有公共前缀（模拟列出目录效果）。缺省值为空字符串
            FileListing fileListing = bucketManager.listFiles(bucket,null,null,10,null);
            FileInfo[] items = fileListing.items;
            for(FileInfo fileInfo:items){
                System.out.println(fileInfo.key);
            }
        } catch (QiniuException e) {
          //捕获异常信息
          Response r = e.response;
          System.out.println(r.toString());
        }
      }
}

触发持久化操作(以视频转码为例)

视频转码

import com.qiniu.common.QiniuException;
import com.qiniu.http.Response;
import com.qiniu.processing.OperationManager;
import com.qiniu.util.Auth;
import com.qiniu.util.StringMap;
import com.qiniu.util.UrlSafeBase64;

public class OperateDemo {

 public static void main(String[] args) throws QiniuException {
  //设置账号的AK,SK
  String ACCESS_KEY = "Access_Key";
  String SECRET_KEY = "Secret_Key";
  Auth auth = Auth.create(ACCESS_KEY, SECRET_KEY);
  //新建一个OperationManager对象
  OperationManager operater = new OperationManager(auth);
  //设置要转码的空间和key，并且这个key在你空间中存在
  String bucket = "Bucket_Name";
  String key = "Bucket_key";
  //设置转码操作参数
  String fops = "avthumb/mp4/s/640x360/vb/1.25m";
  //设置转码的队列
  String pipeline = "yourpipelinename";
  //可以对转码后的文件进行使用saveas参数自定义命名，当然也可以不指定文件会默认命名并保存在当前空间。
  String urlbase64 = UrlSafeBase64.encodeToString("目标Bucket_Name:自定义文件key");
  String pfops = fops + "|saveas/"+urlbase64;
  //设置pipeline参数
  StringMap params = new StringMap().putWhen("force", 1, true).putNotEmpty("pipeline", pipeline);
  try {
    String persistid = operater.pfop(bucket, key, pfops, params);
    //打印返回的persistid
    System.out.println(persistid);
  } catch (QiniuException e) {
    //捕获异常信息
      Response r = e.response;
      // 请求失败时简单状态信息
      System.out.println(r.toString());
      try {
         // 响应的文本信息
        System.out.println(r.bodyString());
      } catch (QiniuException e1) {
          //ignore
      }
  }
 }
}




注：上面的Demo只是针对视频转码，如果需要别的功能比如音视频切片、视频截图、视频拼接只需要修改下上面的fops后面的参数就可以了，
eg: fops = "vframe/jpg/offset/1/w/480/h/360/rotate/90"就表示视频截图了。
下面给出一些常见的数据处理功能，可以根据需要进行选择：
//------------------图片缩放-------------------
fops ="imageView/2/w/200/h/200";

//------------------视频转码-------------------
// fops ="avthumb/flv/vb/229k/vcodec/libx264/noDomain/1";

//------------------图片水印-------------------
String pictureurl = UrlSafeBase64.encodeToString("http://developer.qiniu.com/resource/logo-2.jpg");
fops = "watermark/1/image/" + pictureurl;

//------------------视频切片-------------------
fops = "avthumb/m3u8";
//切片与加密参数
fops = "avthumb/m3u8/vb/640k/hlsKey/MDEyMzQ1Njc4OTEyMzQ1Ng==/hlsKeyUrl/aHR0cDovLzd4bGVrYi5jb20yLnowLmdsYi5xaW5pdWNkbi5jb20vcWluaXV0ZXN0LmtleQ==";

//------------------文档转换-------------------
fops = "yifangyun_preview";

//------------------视频截图-------------------
fops = "vframe/jpg/offset/1/w/480/h/360/rotate/90";

//------------------视频拼接-------------------
//拼接视频片段时要保证所有源的画面长宽值一致
//除去作为数据处理对象的源文件以外，还可以指定最多5个源文件（即总计6个片段）
//所有源文件必须属于同一存储空间
//格式:avconcat/<Mode>/format/<Format>/<encodedUrl0>/<encodedUrl1>/<encodedUrl2>/...
String encodedUrl1 = UrlSafeBase64.encodeToString("http://7xl4c9.com1.z0.glb.clouddn.com/pingjie2.flv");
String encodedUrl2 = UrlSafeBase64.encodeToString("http://7xl4c9.com1.z0.glb.clouddn.com/pingjie3.avi");
fops = "avconcat/2/format/mp4/"+encodedUrl1+encodedUrl2;

//------------------多文件压缩-------------------
//可将若干七牛空间中的资源文件，在七牛服务端压缩后存储
//格式:mkzip/<mode>/url/<Base64EncodedURL>/alias/<Base64EncodedAlias>/url/<Base64EncodedURL>
String encodedfile1 = UrlSafeBase64.encodeToString("http://7xl4c9.com1.z0.glb.clouddn.com/photo1.jpg");
String encodedfile2 = UrlSafeBase64.encodeToString("http://7xl4c9.com1.z0.glb.clouddn.com/vedio1.mp4");
String encodedfile3 = UrlSafeBase64.encodeToString("http://7xl4c9.com1.z0.glb.clouddn.com/audio1.mp3");
fops = "mkzip/2/url/"+encodedfile1+"url/"+encodedfile2+"url/"+encodedfile3;
