After the above-mentioned time of exceeding the time limit, locking operation is asked, it is corresponding above-mentioned then to authorize above-mentioned distributed lock to aforesaid operations request
User terminal sets exceeding the time limit the time for above-mentioned distributed lock, then performs aforesaid operations and asks corresponding operation.
By taking redis distributed locks as an example, mainly by issue orders to realize above-mentioned distributed lock：
(1)setnx(lockkey,expires)
Wherein, lockkey is the key of lock, and all threads are shared, and expires is the expiration time of lock；If setnx is returned
1 is returned, illustrates that the thread is locked, the value of key lockkey is arranged to the time-out time of lock by setnx；If setnx returns to 0, say
Bright lock is obtained by other threads, and process cannot enter critical zone, and lock can only be waited to be released or lock failure.
(2)getset(lockkey,expires)
A process lock expiration time is obtained, and current lock expiration time is set；Only there are one threads to carry out
Getset operates the expiration time for getting a thread.
For example, it is assumed that tri- threads of A, B, C, it is 30 seconds to set time-out time：A threads have obtained process lock, and set
Time-out time for 9 points 30 seconds 30 minutes, A threads have been not carried out in 30 seconds, and two threads of B, C wait and judge whether current time big
In the time-out time of A threads, if A is overtime, B, C are carried out at the same time getset operations, and because getset is synchronous, B threads exist
9 points of the time-out time of A is got during getset 30 minutes and 30 seconds, and 9 points of new time-out time is set 31 minutes and 0 second, C threads exist
The time-out time got during getset be not just 9 points 30 seconds 30 minutes, but B threads set time-out point 9 points 0 second 31 minutes, only
The B threads such as energy have performed release lock or when 9 points compete lock in 0 second 31 minutes again afterwards.
Specifically, after cache server receives the operation requests of user terminal, attempt to set by setnx
The value of lockkey returns to 1 if success (being locked currently without this), successfully obtains lock；Lock is obtained if lock has existed
Expiration time, compared with current time, if time-out, then obtained and locked by getset, and new time-out time is set.
As can be seen that the embodiment of the present invention, the operating right to data cache pool is realized by distributed lock, if should
When distributed lock does not have occupied, user terminal can directly acquire the distributed lock, and by the distributed lock come to number of targets
According to being operated accordingly.If alternatively, the distributed lock is occupied, the distributed lock is waited to discharge automatically or when this
Distributed lock exceeds the time limit and is forced after release, the acquisition request distributed lock.And obtain the distribution institute in user terminal
Afterwards, set one exceed the time limit the time, after the time time is exceeded the time limit more than this, the forcible aborting distributed lock, therefore can prevent because
Cause the distributed lock that cannot discharge to form deadlock for network or other reasons.
204：Identification information is generated, above-mentioned identification information includes the information of above-mentioned first object data and above-mentioned user end
The information at end by above-mentioned identification information feedback to database and above-mentioned user terminal, discharges above-mentioned distributed lock.
Specifically, when cache server by the above-mentioned operating right to data cache pool authorize aforesaid operations request it is corresponding
After user terminal, above-mentioned first object data are got, then generate identification information according to above-mentioned first object data,
In, the information of first object data and the information of above-mentioned user terminal are included in above-mentioned identification information.Then the mark is believed
Breath feeds back to user terminal and database.Then above-mentioned distributed lock is discharged, so that other users terminal is allowed to obtain the operation
Request.
For example, in the second kills activity, killed when the user terminal second to a commodity, then backstage cache server is according to the commodity
Information and user terminal information generate an identification information, represent that the commodity are obtained by above-mentioned user terminal, other
