The method for closing of multithread application provided in an embodiment of the present invention is introduced first below.
A kind of method for closing of multithread application provided by the embodiment of the present invention is applied to electronic equipment.The electricity
Sub- equipment can be with are as follows: desktop computer, portable computer, intelligent mobile terminal, server etc..It is not limited thereto, it is any
Electronic equipment of the invention may be implemented, all belong to the scope of protection of the present invention.It specifically can be applied to the behaviour in electronic equipment
Make in system, is not limited thereto.
Referring to Fig. 1, Fig. 1 is the first pass signal of the method for closing of multithread application provided in an embodiment of the present invention
Figure.The method for closing of multithread application provided by the embodiment of the present invention, may include steps of:
Step 110, in the case where needing to close thread pool, whether the numerical value for detecting thread counter is 0, line
The numerical value of journey counter indicates the active thread of multithread application, what the asynchronous task submitted to thread pool was executed
Volume residual thens follow the steps 120 if so, the numerical value of i.e. detection thread counter is 0.If not, detecting thread count
The numerical value of device is not 0, can be, but not limited to be the step of execution are as follows: return and execute whether the numerical value of detection thread counter is 0
The step of.It in this way can be with the numerical value of constant testing thread counter, until shutoff operation is carried out to thread pool, to close multithreading
Application program.
Wherein, thread counter can be used for recording the active thread of multithread application, submit to thread pool different
The volume residual that step task is executed.Before this step 110, the method also includes: starting thread counter.Into one

When amount changes, start thread counter, thread counter can be started in time in this way to count to thread pool submission
The volume residual that asynchronous task is executed；For another example, when the operating system starts up, start thread counter, it in this way can be with
It keeps thread counter to start always, avoids omitting statistics.
The method of the embodiment of the present invention before this step 110, the method also includes: determine need to thread pool carry out
It closes, can specifically be realized using following possible implementation:
In one possible implementation, when operating system reaches default closedown condition, it is determined as needing to thread
Pond is closed, wherein operating system, which reaches preset closedown condition, can be, but not limited to be preset closing in operating system
Condition, for example be the shut-in time point of setting, the shut-in time point of setting can be to be configured according to user demand, can be with
It is fixed value.Preset closedown condition is that thread all in operating system executes completion for another example, can be closed naturally in this way
Multithread application.Actively determination needs the case where closing to thread pool in this way, and the automation closed may be implemented
Journey, and can obtain needing the case where closing thread pool in time.
In alternatively possible implementation, receive user transmission need to close multithread application
The first turn-off request when, determination need to close thread pool.In this way in operating system of user operational process, need to close
When closing multithread application, the demand of user can satisfy.It is further described below.
It can be realized using following steps in the case where needing to close thread pool in above-mentioned step 110, inspection
Whether the numerical value for surveying thread counter is 0:
111st step, when receiving the first turn-off request for needing to be closed to multithread application, determining is needed
Thread pool is closed.
Wherein, the first turn-off request is contained in turn-off request, and " first " in the first turn-off request is every in order to distinguish
Secondary turn-off request.
Closing for handling turn-off request, which handles thread, can be the thread newly started, be also possible to deposit originally in system
And inactive thread, can satisfy the demand of different scenes in this way.Closing for handling turn-off request handles thread
It can be the thread being not belonging in thread pool, be to be specifically used to handle used in turn-off request close processing thread.Example
Property, the special shutdown hook shutdown hook skill for closing processing thread such as java is used in multithread application
Art executes the closing processing of multithread application, and wherein Java is programming technique.It in this way can be independently of the thread of thread pool
Controlled and handled, can also to avoid asynchronous task of the task as multithread application that will close processing thread, and
Use thread counter.
112nd step handles thread by the closing for handling turn-off request, closes the defeated of multithread application
The step of whether numerical value for entering, and executing the detection thread counter is 0.Here the defeated of multithread application is closed
Enter is in order to avoid in preparing closing process, multithread application also receives always asynchronous task or request, to make
Closing process must be cannot be introduced into.Illustratively, the input of multithread application such as external interface and message queue, stops connecing
Receive the request to multithread application.
It can complete to close in the case where the first turn-off request for needing to close multithread application in this way
Multithread application.

Multithread application can be, but not limited to be webpage web application.Above-mentioned electronic equipment can be intelligent mobile terminal, tool
Body can be smart phone, and multithread application also can be, but not limited to the application program of cell phone software, i.e. application program
(Application, abbreviation APP).Here APP refers to the third party application of smart phone.
Fortune in order to realize many-sided application of active thread in multithread application, in multithread application
Line journey can be according to thread determined by user demand, and these threads are in the state being currently running.Also, line
Journey counter, which can be, counts the active thread in multithread application.Example one, if user needs to multi-thread
All threads are monitored in journey application program, and complete to close the active thread in all threads, then multi-thread
Active thread in journey application program can be the active thread in thread all in multithread application.Corresponding to this
Situation, then thread counter can be for recording the active thread in thread all in multithread application.Example two,
If user needs to be monitored thread preselected in multithread application, and completes to the fortune in all preselected threads
Line journey is closed, then the active thread in multithread application can be in preselected thread in multithread application
Active thread.Corresponding to such case, then thread counter can be used for recording preselected thread in multithread application
In active thread.Wherein, preselected thread can be from thread all in multithread application, pre-select out strong
System, which is closed, will affect the thread that multithread application is closed extremely.For example, preselected thread can be in examination operating system
The thread of remaining task.
The task that active thread in above-mentioned multithread application is submitted to thread pool, then referred to as asynchronous task.In order to
The active thread that multithread application can be grasped in time, the residue that the asynchronous task submitted to thread pool is executed
Quantity, it is therefore desirable to detect the numerical value of thread counter.Error when being written and read in order to avoid the data of thread counter,
The embodiment of the invention also includes: all read-write operations of thread counter are synchronized using lock.
In addition, the numerical value in order to determine thread counter, with convenient to use, method in the embodiment of the present invention further include: really
Determine the numerical value of thread counter.
The embodiment of the present invention can determine the numerical value of thread counter using following any possible implementation.
In one possible implementation, the first step counts current different in the active thread of multithread application
Step task quantity, is determined as the current value of thread counter；
Second step, on the basis of the current value of thread counter, obtain the active thread of multithread application to
The asynchronous task that thread pool is submitted then is done atom adding one to the current value of thread counter and is operated, and by atom adding one
The current value of thread counter after operation is determined as the numerical value of thread counter, does atom adding to thread counter in this way
One operation, may be implemented to have submitted several asynchronous tasks, just add to thread counter several.
Third step, on the basis of the current value of thread counter, the active thread obtained in thread pool is submitted
Asynchronous task be executed into, then the atom operation that subtracts one done to the current value of thread counter, and by the atom operation that subtracts one
The current value of thread counter afterwards is determined as the numerical value of thread counter, wherein current asynchronous task quantity and current number
Value is referred respectively to when demand determines asynchronous task quantity or numerical value, and corresponding asynchronous task quantity or numerical value exist in this way
The asynchronous task that an active thread in thread pool is submitted is executed into, illustrates that active thread task terminates to exit.
The Processing Interface after the active thread task in thread pool can be used in above-mentioned third step, such as Java thread pool
In afterExecute interface realize.AfterExecutee can be all called after task execution generally in thread pool is complete
Interface, wherein thread, which terminates post-process interface afterExecute interface, can refer to java thread pond each work in thread pool
Make the interface that can all call automatically after thread, effect be carried out after each worker thread it is some subsequent
Round-off work.AfterExecutee interface is used for after each worker thread to thread count in embodiments of the present invention
The numerical value of device subtracts one, and it is because this afterExecutee connects that the operation for subtracting one is done using this afterExecutee interface
Mouthful can guarantee the operation for subtracting one, corresponding to each worker thread after can execute it is primary, and execute the time must be
After worker thread.It, can be to be added up on real-time online journey counter, in real time in this way in above-mentioned possible implementation
Obtain the numerical value of thread counter.
It is shown in Figure 2 in alternatively possible implementation, prior to step 110, determine the number of thread counter
Value, comprising:
Step 101, the asynchronous task that the active thread of multithread application is submitted to thread pool is obtained, institute is counted
State the current asynchronous task quantity in the active thread of multithread application, the numerical value as thread counter.
After the asynchronous task that the active thread that step 101 obtains multithread application is submitted to thread pool,
If it is determined that thening follow the steps 110 in the case where needing to close thread pool.The nothing that will not unlimitedly fall into this way
The endless loop that method is closed.
Step 102, it obtains the asynchronous task that an active thread in thread pool is submitted to be executed into, then described in statistics
Current asynchronous task quantity in the active thread of multithread application, the numerical value as thread counter.
Asynchronous task be thread pool is submitted to by the task in already existing active thread, that is, submit it is asynchronous
The active thread (referred to as father's thread 21, as shown in Figure 3) of task is completed before exiting, and asynchronous task would have been completed submission.This
The case where inventive embodiments are tracked the submission of active thread using a thread counter and are executed into, whenever one different
Step task submits (submission, which refers to, not to be needed actually to bring into operation) to arrive thread pool, just does atom adding to the numerical value n of thread counter
One operation；Whenever an active thread terminates just to do the atom operation that subtracts one to the numerical value n of thread counter.Illustratively, such as Fig. 3
Shown, sub thread 1 submits asynchronous task into thread pool, does atom adding one to the numerical value n of thread counter and operates, that is, thread
The numerical value n+1 of counter, sub thread 2 submit asynchronous task into thread pool again, do atom again to the numerical value n+1 of thread counter
Add an operation, that is, the numerical value n+2 of thread counter.
For father's thread, since the time point of asynchronous task submission is earlier than the time point that father's thread 21 terminates, thread
The numerical value of counter, which can first be done after atom adding one operates, is the atom behaviour that subtracts one, that is, the numerical value n+1 of thread counter exists in this way
The end of father's thread 21 is exited, asynchronous task is by the presentation stage of execution the active thread for submitting the asynchronous task, thread meter
The numerical value of number device is consistently greater than 0.Not only consider to wait the active thread in thread pool when closing multithread application in this way
It is executed into, all sub threads of subsequent submission, grandson's thread can also be waited to be executed into automatically, appoint to will not lose
What works, and does not need to do any hypothesis to the specific implementation of the asynchronous call relationship, asynchronous mechanism of multithread application.
Step 120, shutoff operation is carried out to thread pool, to close multithread application.
If this step 120 can be, but not limited to include: thread counter numerical value be 0, closing behaviour is carried out to thread pool
Make, other cleaning operations is closed, to close multithread application.As long as other cleaning operations can be, but not limited to be that can close
The operation for closing multithread application belongs to the protection scope of the embodiment of the present invention.
In the embodiment of the present invention, when the numerical value of thread counter is 0, illustrate multithread application active thread to line
The volume residual that the asynchronous task that Cheng Chi is submitted is executed is 0, carries out shutoff operation to thread pool at this time, can't kill by force
The active thread for falling multithread application, the asynchronous task not being performed submitted to thread pool, would not also cause part
Work is lost.
Shown in Figure 4 in conjunction with shown in Fig. 1, Fig. 2 and Fig. 3, the embodiment of the present invention also provides a kind of multithread application
Method for closing, after step 110, the method also includes: if the numerical value of thread counter is not 0, then follow the steps
103。
Step 103, it is blocked in the closing processing thread of thread counter locked.
Wherein, the lock of thread counter can refer to that a lock of thread counter band itself, the lock of thread counter are used
In the numerical value of janitor thread counter.The closing processing thread of all numerical value for checking thread counter can be in this thread
Locking for counter is blocked；There are active threads to be held after the numerical value change of thread counter, that is, in thread pool
Row is completed, and the closing processing thread locked for being blocked in this thread counter can be waken up.It in this way can be according in thread pool
With the presence or absence of having the case where active thread is executed into, monitoring thread counter, so that it is determined that being to need wake-up or needs
The lock for blocking thread counter, improves the validity of the numerical value change of monitoring thread counter.
Step 104, when being executed into thread pool there are active thread, the lock for being blocked in thread counter is waken up
On closing handle thread, and execute numerical value the step of whether being 0 of the detection thread counter.
It is, can return if the numerical value of thread counter is not 0 and continue to execute step 103, until detecting thread
The numerical value of counter is 0, thens follow the steps 120 pairs of thread pools and carries out shutoff operation, to close multithread application.In this way when
The asynchronous task of all active threads is all executed into when exiting and being submitted without asynchronous task, the numerical value of thread counter
It is not further added by and reduces to 0 therewith since the asynchronous task submitted before is executed into.In this way using thread counter come with
The submission of active thread and the case where be executed into track multithread application, to judge in multithread application
Whether active thread number converges to 0 naturally.
In the embodiment of the present invention, it can use closing processing thread and be blocked in if the numerical value of thread counter is not 0
The closing of thread counter locked handles thread, when being executed into thread pool there are active thread, thread counter
Numerical value can do the atom operation that subtracts one, also, wake up the closing processing thread locked for being blocked in thread counter at this time, again
Whether the numerical value for detecting thread counter is 0, and according in thread pool, there may be the feelings that active thread is executed in this way
Condition, monitoring thread counter improves the validity of monitoring thread counter, and can close multithreading application in time, in turn
Shutoff operation system.
The embodiment of the present invention can be applied in various multithread applications, be answered using thread counter tracking multithreading
With the submission situation of active thread in program, the opportunity that can be submitted to asynchronous task is required, but not to multithreading application
Actual service logic and asynchronous call relationship are not done any it is assumed that guarantee that multithread application is being closed inside program
With any work is not lost in restarting process, improve the service quality of multithread application.
It continues with and the closing device of multithread application provided in an embodiment of the present invention is introduced.
