Can according in data source URL information and data source drive, generate corresponding data source, and will be in the write-in of the data source of generation
It deposits.However, server can generate in a large amount of data source write-in memory in business procession, occupying for memory will lead to
Rate is higher, reduces the performance of system.
To solve the above-mentioned problems, the embodiment of the invention provides a kind of management method of data source and device, Ke Yiying
For server, which can receive the data access request of terminal transmission, and return to corresponding data source to terminal, eventually
End can then be connect according to the data source with Database, and then the accessible database.
Based on method of the invention, server can be according to the last visit of each data source in the data source information table of storage
Ask the time, judge the data source it is current do not access whether duration is greater than preset duration, do not accessed if the data source is current
Duration is greater than preset duration, i.e. the data source is not visited for a long time, then the data source can be determined as to be deleted by server
Data source, then, server can delete data source to be deleted from memory, and number to be deleted is deleted from data source information table
According to the corresponding list item in source.Based on above-mentioned processing, server can be deleted in memory and be not interviewed for a long time according to data source information table
The data source asked, and then the occupation rate of memory can be reduced, improve the system performance of server.
Referring to Fig. 1, Fig. 1 is a kind of flow chart of the management method of data source provided in an embodiment of the present invention, and this method can
With the following steps are included:
S101: according to the last access time of each data source in the data source information table of storage, judge that the data source is worked as
Preceding does not access whether duration is greater than preset duration.
Wherein, preset duration can be rule of thumb configured by technical staff.Data source information table can be server
It is generated, and is stored in local according to the data access request received.It can recorde server generation in data source information table
Data source last access time.The current duration that do not access of data source can be for from the last access time of data source to working as
The duration at preceding moment.
In an implementation, server can read the data source information table being locally stored in default renewable time, obtain data
The last access time of each data source recorded in source information table, and then can be according to current time and each data source most
Access time afterwards, judge each data source it is current do not access whether duration is greater than preset duration.
In this step, default renewable time can be rule of thumb configured by technical staff, for example, default renewable time
It can be the fixed moment in period, or at the time of the data access request that server receives terminal transmission corresponds to.
When reaching default renewable time, server can successively obtain local data source according to default search order
The last access time of each data source recorded in information table.For each data source, server can calculate the data source
Last access time and current time between duration, as the data source it is current do not access duration, then, server can
With judge the data source it is current do not access whether duration is greater than preset duration.Wherein, default search order can be by technology people
Member is rule of thumb configured, for example, the time that default search order can generate each data source for server (is properly termed as
Initialization time) sequencing.
S102: if the duration that do not access of the data source currently is greater than preset duration, which is determined as to be deleted
Data source.
In an implementation, for each data source, when server determine the data source it is current do not access duration be greater than it is default
When duration, which can be determined as data source to be deleted by server.
Optionally, for a certain data source, when server determines that the current duration that do not access of the data source is less than or waits
When preset duration, server can be without any processing, then to the data source, and server can be suitable according to default inquiry
Sequence continues to judge that the current of next data source does not access whether duration is greater than preset duration, until server believes data source
All data sources judgement recorded in breath table terminates.
S103: deleting data source to be deleted from memory, and deletes data source to be deleted from data source information table and correspond to
List item.
In an implementation, for each data source recorded in data source information table, data source to be deleted that server is determined
It can be one, or multiple.Then, server can delete the data source to be deleted determined from memory, and
The corresponding list item of data source to be deleted is deleted from data source information table.
In this step, for each data source, server can be when determining the data source be data source to be deleted, by this
Data source is deleted from memory, and the corresponding list item of the data source is deleted from data source information table, and then, server can be by
According to default search order, continue to judge whether next data source is data source to be deleted.Alternatively, server can also determine first
After all data sources to be deleted recorded in data source information table out, then, then by each data source to be deleted determined from interior
Middle deletion is deposited, and deletes the corresponding list item of each data source to be deleted from data source information table.For server from memory
Data source to be deleted is deleted, and deletes the time of the corresponding list item of data source to be deleted, the present embodiment from data source information table
It is not defined.
As it can be seen that the method based on the present embodiment, server can delete data source not visited for a long time in memory, most
The initial frequencies for possibly reducing data source greatly, to reduce the calculating pressure of system.
Optionally, server can also further screen in not accessing data source of the duration greater than preset duration, with true
Make data source to be deleted.Specifically, data source information table can also record initialization time and the access times of data source.
If a certain data source it is current do not access duration greater than preset duration, by the data source be determined as data source to be deleted it
Before, this method may also comprise the following steps::
Step 1 calculates the access of the data source according to current time, the initialization time of the data source and access times
Frequency.
Wherein, for each data source, initialization time and the visit of the data source can also be recorded in data source information table
Ask number, the initialization time of data source namely server generate the time of the data source, the access times of data source namely from
Until generating the data source to current time, the accessed number of the data source.
In an implementation, for a certain data source, when server determines that the current access duration of the data source is greater than default
When long, the initialization time of the data source recorded in the available data source information table of server and access times.Then, it takes
Business device can calculate the data source and work as according to the access times at current time, the initialization time of the data source and the data source
Preceding access frequency.For example, server, which can calculate the duration between current time and the initialization time of the data source, (can claim
For there are durations), then, server can calculate the data source access times and the data source there are the quotient of duration,
The access frequency current as the data source.
Step 2, if the access frequency of the data source is greater than default access frequency, when by the last access of the data source
Between be updated to current time.
Wherein, default access frequency can be rule of thumb configured by technical staff.
In an implementation, when server determines that the current duration that do not access of a certain data source is greater than preset duration, and the data
When the current access frequency in source is greater than default access frequency, server can be by the data source recorded in data source information table
Last access time is updated to current time so that server next time can last access updated according to the data source when
Between, judge the data source does not access whether duration is greater than preset duration.
The data source is determined as wait delete by step 3 if the access frequency of the data source is not more than default access frequency
Except data source.
In an implementation, when server determines that the current duration that do not access of a certain data source is greater than preset duration, and the data
When the current access frequency in source is less than or equal to default access frequency, which can be determined as number to be deleted by server
According to source, and then the data source can be deleted from memory, improve the performance of system.
Optionally, server can also determine whether to delete the data source according to the deletion License Status of a certain data source.
Specifically, data source information table can also record the deletion License Status of data source, deleting License Status can be to allow to delete
Or do not allow to delete.
For a certain data source, server according to current time, the data source initialization time and access times, meter
Before the access frequency for calculating the data source, this method may also comprise the following steps:: obtaining the data source in data source information table
Deletion License Status；If the deletion License Status of the data source is to allow to delete, judges that the data source is current and do not access
Whether duration is greater than preset duration.
Wherein, the deletion License Status of data source can be rule of thumb configured by technical staff.Delete License Status
It can be to allow to delete or do not allow to delete.If the deletion License Status of a certain data source is to allow to delete, then it represents that service
Device can delete the data source, if the deletion License Status of the data source is not allow to delete, then it represents that server cannot
Delete the data source.
In an implementation, for a certain data source, server can obtain the data recorded in data source information table first
The deletion License Status in source, if the deletion License Status of the data source is to allow to delete, server can further judge
The data source it is current do not access whether duration is greater than preset duration, if the data source it is current do not access duration be greater than it is default
Duration, then server can calculate the visit of the data source according to current time, the initialization time of the data source and access times
It asks frequency, and carries out respective handling.
Alternatively, server can also first determine whether the data source it is current do not access whether duration is greater than preset duration, such as
The current duration that do not access of the fruit data source is greater than preset duration, and server can further judge the deletion license of the data source
Whether state is to allow to delete, if the deletion License Status of the data source is to allow to delete, server can be according to current
Moment, the initialization time of the data source and access times calculate the access frequency of the data source, and carry out respective handling.It is right
In above-mentioned judgement sequence, the present embodiment is not defined.
In addition, server can not to the data source if the deletion License Status of the data source is not allow to delete
Carry out any processing.Then, server can obtain the deletion License Status of next data source according to default search order, and
Carry out respective handling.
Optionally, server can also update data source information table according to the data access request of terminal.Specifically, data
Source information table can also record the corresponding data source URL of data source and user name, and this method may also comprise the following steps::
Step 1, according to data source information table, is judged whether there is when receiving the data access request of terminal transmission
Target data source corresponding with the data source URL and user name that are carried in data access request.
Wherein, it is corresponding can also to record the data source when generating a certain data source in data source information table for server
Data source URL and user name, server can determine whether terminal has corresponding data access authority according to user name.
In an implementation, terminal can send data access request to server, to access corresponding database, data access
User name and data origin url can be carried in request.Correspondingly, server then can receive the data access of terminal transmission
Request, parsing data access request obtain user name and data origin url.
Then, server can be inquired in data source information table, judge in data source information table with the presence or absence of with
The mark of the user name and the corresponding data source of data origin url that are carried in data access request, namely judge whether deposit in memory
With the user name and data origin url corresponding data source (i.e. target data source) that are carried in data access request.
Step 2 generates target data source according to data access request, and in data source if there is no target data source
The corresponding list item of target data source is added in information table.
In an implementation, when server determines that target data source is not present in memory, server can be according to data access
Request generates target data source, and the method that server generates target data source is same as the prior art, and details are not described herein again.Together
When, server can also add the corresponding list item of target data source in data source information table.Illustratively, server can be
Initialization time (i.e. current time), the access times (i.e. 1), user name, number of target data source are recorded in data source information table
According to origin url and last access time (i.e. current time).
In addition, target data source after generating target data source, can be sent to terminal by server, so that terminal can be with
Access corresponding database.
Target data source is sent to terminal if there is target data source by step 3, and it is corresponding to update target data source
List item.
In an implementation, when server determines in memory that server can send out target data source there are when target data source
It send to terminal.Meanwhile server can also update the corresponding list item of target data source.
In this step, the last access time of target data source can be updated to current time by server, and update mesh
Mark the access times of data source.Illustratively, the current access times of the available target data source of server, and will be current
Access times add 1, to update the access times of target data source.Optionally, the information that server can also provide data source is looked into
It askes.Specifically, this method may also comprise the following steps:: when receiving data query instruction, data source information table being sent
To user terminal, so that the information recorded in user terminal display data sources information table.
In an implementation, user can send data query instruction to server by user terminal, to inquire current number
According to the information in source, correspondingly, data source information table can be sent to user's end when server receives data query instruction
End, user terminal then can information to record in display data sources information table.
In addition, the corresponding data source driving of data source can also have been recorded in data source information table, for user's browsing.
As it can be seen that the monitoring of data source may be implemented in the method based on the present embodiment, user is allowed to pass through user terminal
