Fig. 2 shows the flow chart of paged data synchronous method 200 according to an embodiment of the invention.As shown in Fig. 2
In step S210, mobile terminal 300 sends homepage data synchronization request to obtain homepage data to the webserver 500, first
Page data synchronization request includes that data update timestamp.Certainly, homepage number is sent to the webserver 500 in mobile terminal 300
Before according to synchronization request, it is 0 that first initialization data refresh time stamp and data update timestamp respectively.
Then, into step S220, the webserver 500 please in the homepage data syn-chronization for receiving the transmission of mobile terminal 300
After asking, homepage data are obtained from the data storage device of database server 900.Fig. 3 is shown according to a reality of the invention
The flow chart of the step of applying the acquisition homepage data of example S220.As shown in figure 3, in step S221, the basis of the webserver 500
Data update timestamp and reference data amount, and, first data corresponding with reference data amount is obtained from data storage device
The data syn-chronization timestamp of information and the last item data message.It is 0, the webserver 500 that now data update timestamp
It is that can determine whether page data synchronization request headed by current request to update timestamp according to the data, then made current time plus 5 minutes
It is that new data update timestamp, to obtain the data of newest one page in data storage device as homepage data.After renewal
It is 1481432071005 that data update timestamp, plus the purpose of 5 minutes is taken with database to solve the webserver 500
Time difference problem between business device 900, it is to avoid lose latest data, so that it is guaranteed that obtaining the integrality of data.Table 1 shows
The storage example of data message in data storage device, it is specific as follows shown：
Table 1
As shown in table 1, include per data information Data Identification, data syn-chronization timestamp, the time that places an order, forwarding time and
Operating time, data syn-chronization timestamp is the maximum in the time of placing an order, forwarding time and Action Events.It should be noted that
Also include data content in data message, for ease of statement, not shown in table 1.As can be seen from Table 1, data message be by
Sequentially stored according to data syn-chronization timestamp order from big to small, i.e., above, old data arrangement exists new data arrangement
Below, and newest data information data syn-chronization timestamp be 1481432061220, less than data update timestamp,
Ensure that the homepage data for getting include latest data information, in the absence of loss or omission.In this embodiment, benchmark
Data volume is set to 3, and the data syn-chronization timestamp for obtaining the first data information corresponding with reference data amount is
1481432061220, corresponding data mark 1008, the data syn-chronization timestamp 1481432061008 of the last item data message,
Corresponding data mark 1006.
Next, into step S222, data syn-chronization timestamp is not less than the last item number in obtaining data storage device
It is believed that the data syn-chronization timestamp and the no more than data message of the data syn-chronization timestamp of the first data information of breath are used as head
Page data.The data syn-chronization timestamp of the last item data message and the first data information is respectively 1481432061008 Hes
1481432061220, not less than 1481432061008 and no more than 1481432061220 data syn-chronization timestamp is
1481432061220th, 1481432061010 and 1481432061008, the corresponding number of data syn-chronization timestamp 1481432061220
According to mark 1008, the corresponding data of data syn-chronization timestamp 1481432061010 mark 1007, data syn-chronization timestamp
1481432061008 difference corresponding data marks 1006 and 1005, the final data message for obtaining Data Identification 1008~1005
As homepage data.
After the webserver 500 gets homepage data, start to perform step S230, by homepage data is activation to movement eventually
End 300.And mobile terminal 300 receives the homepage data that the webserver 500 is returned, and in step S240, by homepage data
In the data syn-chronization timestamp of the first data information be assigned to Refresh Data timestamp, the data of the last item data message are same
Step timestamp is assigned to data and updates timestamp.In this embodiment, the value of Refresh Data timestamp is updated to
1481432061220, the value that data update timestamp is updated to 1481432061008.It is obvious that mobile terminal 300 is being obtained
To after homepage data, can it be processed to show corresponding page in screen.Because the data for typically getting are Json
The data of form, whether first the data are carried out with dissection process correct to judge the request for returning.Specifically, according to Json
Returncode fields in the data of form are judged, if returncode is 0, illustrate that the data for returning are correct,
Data in parsing result fields, if returncode is not 0, corresponding mistake are carried out according to the value of returncode
Treatment.Further, if returncode is -666, illustrate that user right sends change, first obtain new user right
List, then judges whether also there is the authority for obtaining synchrodata, if then obtaining data again, if being pointed out without if
To user temporarily without the authority of the synchronous data, while the local data deletion before in mobile terminal 300 is no longer shown.If
Returncode is -200, then illustrate user's different-place login, then jump back out to login interface.If returncode is -1, table
There is mistake in bright this time request, mobile terminal 300 does not carry out Json data parsings, the close friend that straight-forward network server 500 is returned
Error message is prompted to user.An example of homepage data is shown below is, it is specific as follows：
{"returncode":0,
"message":" success ",
"result":{"rowcount":0,"pagecount":0,"pageindex":0,"lastupdatetime":
0,
"list":[{"startdatetime":1481432061220,"lastupdatetime":481432061008,

}
As can be seen that the value of returncode is 0 from above-mentioned data, illustrate that the data for returning are correct, and then parse
The data are localized treatment by the data in result fields, and using UI threads by the content revealing in data to ought
In the preceding page.Certainly, if homepage data synchronization request is without returned data, the temporary no data page is shown.Performing localization
During treatment, entity conversion first is carried out to the homepage data for getting, the list of entities data after conversion are deposited to movement
In tables of data in the local SQLite databases of terminal 300.It is worth noting that, being needed first by data during storage homepage data
Table is emptied, then the homepage data that will be obtained are placed wherein.
And in list fields, there is startdatetime and lastupdatetime parameters, its value is respectively
1481432061220 and 1481432061008, the two parameters correspond in homepage data the first data information and last respectively
The data syn-chronization timestamp of one data information, above-mentioned assignment updates step, actually by startdatetime
Refresh Data timestamp is assigned to respectively with the value of lastupdatetime and data update timestamp.
In step s 250, the slide in response to user is instructed, and mobile terminal 300 sends to the webserver 500
To obtain lower page of data, lower page of data synchronization request includes that data update timestamp to lower page of data synchronization request.Now,
Current page has slid into Bottom of Page and has continued to slide up.According to one embodiment of present invention, mobile terminal 300 is being asked
Homepage data are just got before seeking lower page of data, data update timestamp, and assignment is updated to 1481432061008.Need
Bright, the lower page of data synchronization request in the present invention includes that all paged datas in addition to homepage data synchronization request are same
Step request, statement of the lower one page only with respect to current page.
The webserver 500 receive mobile terminal 300 send lower page of data synchronization request after, into step
S260, obtains lower page of data from the data storage device of database server 900.Fig. 4 is shown according to of the invention one
Under the acquisition of embodiment the step of page of data S260 flow chart.As shown in figure 4, in step S261, the webserver 500
According to data update timestamp and reference data amount, from data storage device obtain it is corresponding with reference data amount, first
