6.3.5.3 分块检查 在Service 中定义分块检查方法：
[mw_shl_code=applescript,true]//得到块文件所在目录 private String getChunkFileFolderPath(String fileMd5){ String fileChunkFolderPath = getFileFolderPath(fileMd5) +"/" + "chunks" + "/";
return fileChunkFolderPath;
} //检查块文件 public CheckChunkResult checkchunk(String fileMd5, String chunk, String chunkSize) {
//得到块文件所在路径
String chunkfileFolderPath = getChunkFileFolderPath(fileMd5);
//块文件的文件名称以1,2,3..序号命名，没有扩展名
File chunkFile = new File(chunkfileFolderPath+chunk);
if(chunkFile.exists()){
return new CheckChunkResult(MediaCode.CHUNK_FILE_EXIST_CHECK,true);
}else{
return new CheckChunkResult(MediaCode.CHUNK_FILE_EXIST_CHECK,false);
} }

6.3.5.4 上传分块
在Service 中定义分块上传分块方法：
[mw_shl_code=applescript,true]//块文件上传 public ResponseResult uploadchunk(MultipartFile file, String fileMd5, String chunk) {
if(file == null){
ExceptionCast.cast(MediaCode.UPLOAD_FILE_REGISTER_ISNULL);
}
//创建块文件目录
boolean fileFold = createChunkFileFolder(fileMd5);
//块文件
File chunkfile = new File(getChunkFileFolderPath(fileMd5) + chunk);
//上传的块文件
InputStream inputStream= null;
FileOutputStream outputStream = null;
try {
inputStream = file.getInputStream();
outputStream = new FileOutputStream(chunkfile);
IOUtils.copy(inputStream,outputStream);
} catch (Exception e) {
e.printStackTrace();
LOGGER.error("upload chunk file fail:{}",e.getMessage());
ExceptionCast.cast(MediaCode.CHUNK_FILE_UPLOAD_FAIL);
}finally {
try {
inputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
try {
outputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return new ResponseResult(CommonCode.SUCCESS); }
//创建块文件目录
private boolean createChunkFileFolder(String fileMd5){
//创建上传文件目录
String chunkFileFolderPath = getChunkFileFolderPath(fileMd5);
File chunkFileFolder = new File(chunkFileFolderPath);
if (!chunkFileFolder.exists()) {
//创建文件夹
boolean mkdirs = chunkFileFolder.mkdirs();
return mkdirs;
}
return true;
