Split invoice.After the setting for completing information, task is stored in task list, wait task is subsequently periodically performed.
Then using task scheduling instruments such as Quartz, timing captures and performed invoice and imports task, in this way, can be preferable
Control task perform rhythm, and perform frequency setting can need to adjust at any time with business.Wherein " timing " can be
Specified time, the operation of once crawl importing task is performed at regular intervals, interval time can enter according to mission requirements are imported
Row adjustment, for example, it can be set to for 30 minutes.
According to database performance, if such as currently used database import data every time and be up to 500 (this data roots
May have different settings according to the difference of the database used, and can be adjusted according to importing demand), then one is grabbed every time
Individual task, just according to 500 one section, whole importing task is split into multiple segmentation tasks to perform import operation.
In view of this, the data volume of the task of user's importing invoice need not limit, it is only necessary to press invoice importing task
Split into according to numbering multiple, then asynchronous execution, import system perform automatically, without special messenger's pending completion such as always,
So as to improve user experience.And the quantity for splitting invoice section can adjust at any time according to database performance situation, logarithm is reduced
According to storehouse operating pressure.
In addition, in the embodiment of the present invention, importing task is being split into during multistage is performed, it is necessary to each point
Segment data corresponding to section task carries out anti-heavy inspection.I.e. before database is imported, it is ensured that the data in this section do not have quilt
Storage, to avoid the repetition of data from importing.
As it was previously stated, anti-heavy-duty machine system can be carried out anti-heavy using caching technology, it can also utilize and be set during database purchase
Unique index carry out it is anti-heavy.By caching technology anti-re-graduation is carried out to test, because inquiry velocity is fast in caching, therefore can provide compared with
The inquiry of database higher performance, and the inquiry pressure to database can also be reduced., can be with but if caching goes wrong
Anti- re-graduation is carried out using the unique index of database to test.
After the data in judging segmentation task and non-duplicate importing, by this section of invoice data batch deposit database, hair
Draft bank is set as not reproducible in database, i.e., invoice codes and invoice number is arranged into unique index, if repeated,
Import failure.After the completion of the importing task, continue to capture relatively morning task creation time and the importing task not being performed is led
Enter operation.Idiographic flow see Fig. 2.
