When being changed using the present invention, before this step, also include：The thread pool with initial capacity is created,
The thread pool includes multiple threads that can independently carry out file format conversion.It is whole in the server using the present invention or intelligence
Need to create thread pool on end, when the server or intelligent terminal start, create thread pool, the thread pool is configured with just
Beginning capacity, it is ensured that the form conversion of multiple files.The quantity of the thread pool is not limited, and can be 100,1000,2000 etc.,
Can be created according to the needs of the server or intelligent terminal.The more files that can be processed simultaneously of thread are more,
But, the requirement to server or intelligent terminal is higher.
It is described to receive the request for entering row format conversion for request to specified file, including：Receive a client to initiate
For request specified file is entered row format conversion one request, receive multiple client initiate user's request to specify
File enters multiple identical requests of row format conversion, receives multiple client while that what is initiated enters to specified file for request
What multiple identical requests of row format conversion, one client of reception were initiated enters row format to multiple specified files for request
Conversion multiple requests, receive multiple client initiate for request multiple specified files are entered row format conversion it is multiple please
Ask.This is all within the scope of the present invention.
Step S102：One thread is transferred from the thread pool for pre-building according to the request.
Before this step, when receiving for asking to enter specified file the request of row format conversion, identification is needed
The information of the specified file.The information of the specified file, including the information such as the unprocessed form of the specified file, title,
The unprocessed form refers to the form of the specified file for also not entering row format conversion.The head of the specified file can be passed through
Information and/or suffix name are recognizing the specified file.After the information for recognizing the specified file, according to the specified file
Information, search whether to be directed in the thread run in thread pool the thread that the specified file enters row format conversion,
If having, the thread operation is waited to complete, response of the file after the thread is changed as the request；If no,
Then need from the thread pool for pre-building to transfer a thread to enter the specified file row format conversion.By identification,
May determine that whether two specified files are same specified files, after being, call the basis of thread.
In this step, the request is referred to for asking specified file to enter the request of row format conversion, being one
What individual client is initiated, or multiple client was initiated.Can be a client once initiate to it is described specify
File enters the request of row format conversion, can client repeatedly initiate row format entered to the specified file change
The request of multiple identicals, can the multiple different time of multiple client initiate row format entered to the specified file change
Multiple identical requests, can be multiple clients while that what is initiated enters the multiple identical of row format conversion to the specified file
Request, it can be seen that above-mentioned several situations be all same specified file is entered row format conversion.By to the specified text
The identification of part, it can be determined that whether the specified file gone out in multiple requests is same specified file.
When the request for entering row format conversion to same specified file is received, then adjust from the thread pool for pre-building
Take a thread and enter row format conversion.In this manner it is possible to avoid repetition from entering row format conversion to same file, it is possible to reduce money
The waste in source.Certainly, when the request for entering row format conversion to specified file is received, it is also possible to the specified file is not entered
Row identification, can call multiple threads from the thread pool to process and enter the multiple of row format conversion to same specified file
Identical is asked, and this is also within the scope of the present invention.
When receive multiple client and meanwhile initiate for request specified file is entered row format conversion it is multiple identical
Request when, it is only necessary to random that a thread is transferred from the thread pool for pre-building according to one of request, other requests
The thread operation is waited to complete, response of the file after the thread is changed as the request.
When receive multiple client different time initiation for request specified file is entered row format conversion it is multiple
When identical is asked, then transfer a thread to process the request of earliest initiation from the thread pool for pre-building, other
Request waits the thread operation to complete, response of the file after the thread is changed as the request.
Multiple specified files are entered with row format for request turn when receive that a client or multiple client initiate
During the multiple different request changed, need according to the number of the plurality of specified file to transfer corresponding multiple threads.For example,
When one or more users file different to five initiates the request of form conversion, needs transfer five lines from thread pool
Journey, to enter row format conversion to five different files respectively.The plurality of request can be simultaneously emitted by, it is also possible to
It is that different time sends, all within the scope of the present invention.The plurality of request is simultaneously emitted by, it is meant that, while
Receive the plurality of request.Multiple specified files are entered with the multiple different of row format conversion for request when receiving simultaneously
During request, then multiple threads are transferred at random, row format conversion is entered respectively using independent thread to each file.Work as different time
Receive when multiple specified files being entered with the multiple different request of row format conversion for request, then according to the suitable of the request
Sequence transfers thread at random from thread pool.
By adopting Thread Pool Technology, it is possible to achieve while multiple files are entered with the process of row format conversion, it is not necessary to arrange
The threads such as team, can reduce the time of on-line loaded file, save the time of online preview, and then improve treatment effeciency；Meanwhile,
Can solve the problem that concurrent situation during online preview file, it is possible to use family is while the multiple files of online preview.
Step S103：Using the thread dispatching transition components.
Before this step, need to be identified the unprocessed form of specified file, with information before to specified file
The method being identified is identical, recognizes the original of the specified file by the header and/or suffix name of the specified file
Beginning form.Then, according to the unprocessed form and object format of the specified file selecting transition components.The object format can
Be user oneself select, or server or intelligent terminal acquiescence.The transition components can be by the original
The file of beginning form is converted into the component of the file of object format.For example, PDFCreator components, OpenOffice components etc..
Step S104：Enter row format conversion to the specified file using the thread and the transition components, turned
File after changing.
In this step, the thread enters row format conversion using the transition components to the specified file, and obtains
File after conversion.After this step, can also include：Judge whether other requests also for the specified file；
If no, the file after the conversion is stored in caching；If having, the specified text is processed according to described other requests
Part, using the file processed according to described other requests as the request response.Described other requests include：The conversion
Previewing file effect afterwards is bad, needs to change again；User also needs to translate the file into into other forms；User only needs to pre-
Certain part look in file etc..When not to other requests of specified file, the file storage after the conversion is arrived into slow
In depositing, and discharge process.
Wherein, the caching includes：Server buffer and/or front end player caching, user can be selected as needed
The file after conversion is downloaded, meanwhile, user can also download the specified file before conversion, all within the scope of the present invention.
As such, it is possible to meet the demand of user as far as possible, it is possible to increase Consumer's Experience.
After conversion, the file after conversion can also store the caching for using the server or intelligent terminal of the present invention
In.The server or intelligent terminal can also store the specified file before conversion.Before step S102, can also include：
The file after changing to the specified file is searched whether in the buffer；If having, institute is called from the caching
The file after conversion is stated as the response of the request.To specified file enter request that row format change for request receiving
When, by recognizing the specified file, then, after in the caching searching whether to change the specified file
File, if not having, according to it is described request a thread is transferred from the thread pool for pre-building, then perform step below
Suddenly；If having, the file after the conversion is directly called from the caching as the response of the request.Turning through form
After changing, the partial information of file header is constant, can be searched whether by File header information to the specified file
File after being changed.By this method, can avoid conversion being repeated several times to same file, it is to avoid the wave of resource
Take, being capable of save resources and time.
It is described search whether in the buffer to change the specified file after file and described in thread pool
Search whether to be directed to the thread that the specified file enters row format conversion in the thread of middle operation, can carry out simultaneously,
Can independently carry out, be independent of each other, it is also possible to combine to judge whether the step of performing below, this is all in the guarantor of the present invention
In the range of shield.For example, the thread for entering row format conversion to specified file is not found in thread, is not looked in the buffer yet
The file after corresponding conversion is found, at this moment, it is possible to a thread is transferred from the thread pool for pre-building, after then performing
The step of face.
Step S105：Using the file after the conversion as the response of the request, allow described in the online preview of user
File after conversion.
