It is shown, it is somebody's turn to do the task processing method based on thread pool and may comprise steps of.
In step s 110, the task refusal instruction in receiving thread pond.
Thread pool is that task is added into task buffer queue, Ran Hou in a kind of multiple threads form, processing procedure
These tasks are performed automatically after creating thread.After tasks carrying is finished, the thread will be reclaimed automatically.
Thread is also referred to as Lightweight Process (LightWeight Process, LWP), is the minimum list that program performs stream
Member.
Task refusal instruction is the instruction that thread pool is sent for the task that refusal receives.
It is understood that the task disposal ability of each thread pool is limited in computer equipment.When the task of thread pool
When amount transfinites, it will refuse to receive new task, and task refusal instruction is sent for the task.
Thus, after thread pool sends task refusal instruction for task, computer equipment will receive task refusal
Instruction.
In a specific exemplary embodiment, thread pool A maximum thread is maxPoolSize.As thread pool A
In number of threads reach maxPoolSize, and task buffer queue is full, if now still submitting new appoint to thread pool A
Business, thread pool A will refuse to receive the task, and send task refusal instruction for the task.
In step s 130, the task that instruction acquisition is refused by thread pool is refused according to task.
It is understood that each task has its corresponding identification information in computer equipment.
It should be noted that task refusal instruction is that thread pool is sent for the refusal of some task, task refusal
Include the identification information of the task in instruction, such as task sequence number.
The identification information thus refused according to task in instruction can find being rejected for task.
In step S150, pass through the sub- thread pool process task of thread pool.
Sub- thread pool is the dependent thread pond for belonging to some thread pool in computer equipment.
The reference of the thread pool belonged to it is saved in sub- thread pool, the task buffer in the thread pool of its ownership is shared
List, so as to the task buffer queue for the thread pool for obtaining its ownership, and then assists its thread pool belonged to carry out task
Processing.
For example, computer equipment there are thread pool A and sub- thread pool B, sub- thread pool B is thread pool A thread pool,
Sub- thread pool B can obtain thread pool A task buffer list.
After sub- thread pool reception task, the thread new by creating performs being rejected for task, so that the task is obtained
Processing.
Using method as described above, after task is refused by thread pool, by the sub- thread pool of the thread pool to this
Business is handled, it is to avoid go out the phenomenon that current task cannot be handled, and substantially increases the energy that task processing is carried out based on thread pool

Lower step.
In step S210, judge that thread pool whether there is sub- thread pool, if NO (N), then perform step S230, if
It is (Y), then performs step S150.
After being refused by thread pool for task is obtained, by having judged whether that thread pool is subordinated to the thread pool, enter
And determine the thread pool and whether there is sub- thread pool.
Judge whether that thread pool is subordinated to the thread pool, that is, judged that the thread pool can be with the presence or absence of sub- thread pool
By judging whether the thread pool to other thread pools shares task buffer queue.
It should be noted that thread pool to other thread pools share task buffer queue when, will in the thread pool add
Task sharing information.
Thus, by searching task sharing information in each thread pool, find the thread added with task sharing information
Chi Hou, determines to share the sub- thread pool of task buffer queue in the thread pool according to task sharing information.
When sub- thread pool is not present in the thread pool for refusing task, then sub- thread pool is created for the thread pool；When refusal is appointed
When the thread pool of business there are sub- thread pool, then pass through sub- thread pool process task.
It is that thread pool creates sub- thread pool in step S230.
According to the task buffer list of thread pool, a dependent thread pond, i.e., sub- thread pool are set up for the thread pool, and set
The task buffer list for putting the thread pool is shared to sub- thread pool.
When creating sub- thread pool, task sharing information is added in thread pool, so that sub- thread pool can share the thread
Task buffer queue in pond, realization is monitored to the task in the thread pool.
In a specific exemplary embodiment, after the thread pool reception task that task disposal ability transfinites, by pin
Task refusal instruction is sent to the task.Refused to instruct according to the task, when sub- thread pool is not present in the thread pool, application is
The thread pool creates sub- thread pool, and then performs being refused by thread pool for task by the thread of the sub- thread pool.
By method as described above, after thread pool is refused task, when the thread pool, which is not present, sub- thread pool, it is
The thread pool creates sub- thread pool, and then handles being refused by the thread pool for task by sub- thread pool, it is to avoid goes out current task and obtains
Less than the phenomenon of processing, the ability that task processing is carried out based on thread pool is substantially increased.

Task buffer queue detection is detected to whether also there is being not carried out for task in task buffer queue.
In step S430, task buffer queue is space-time in the sub- thread pool of thread pool and thread pool, destroys line
Cheng Chi thread pool.
It is understood that when in the sub- thread pool of thread pool and the thread pool task buffer queue be space-time, show
The processed task of sub- thread pool of thread pool and the thread pool is finished, now, and the sub- thread pool of thread pool and the thread pool is equal
In idle condition, tasks carrying is had no.
Therefore, if task buffer queue is space-time in the sub- thread pool of thread pool and the thread pool, sub-line journey is still retained
Pond, will cause system resource waste.Now, even if there is new task to need processing, the thread pool also can be performed accordingly, destroy son
Thread pool does not interfere with task disposal ability yet.But by destroying the sub- thread pool of the thread pool, it can but avoid system resource
Waste.
Using method as described above, task buffer queue is sky in the sub- thread pool of thread pool and the thread pool
When, the sub- thread pool of the thread pool is destroyed, so as to avoid the waste of system resource when not influenceing task to handle.

In step S151, in the task buffer queue that task is inserted to sub- thread pool.
It should be noted that when thread pool carries out task processing, task is first inserted to the task buffer queue of thread pool, when
When the thread of thread pool is not up to thread capacity, the task in the thread execution task buffer queue new by creating.
Sub- thread pool is received after new task, in the task buffer queue that the task is inserted to its own, for sub-line journey
Pond created and performed after thread.
In step S153, judge whether the number of threads of sub- thread pool reaches default thread capacity, if NO (N), then
Step S155 is performed, if yes (Y), then the task in the task buffer queue of sub- thread pool wouldn't be handled.
It should be noted that thread pool is preset with thread capacity.By being controlled to the number of threads in thread pool,
Avoid because of thread occupying system resources excessive in thread pool and caused by system crash.
When number of threads in group thread pool is not up to default thread capacity, by creating new line in sub- thread pool
Journey is handled the task in task buffer queue；When the number of threads of group thread pool reaches default thread capacity, need
Handled after the tasks carrying being carrying out is finished, then to the task in task buffer queue.
In step S155, pass through the task in the thread execution task buffer queue of sub- thread pool.
Using method as described above, when the number of threads of sub- thread pool is not up to default thread capacity, using sub-line
Cheng Chi thread carries out performing the task in task buffer queue, it is to avoid reach that default thread holds in the number of threads of sub- thread pool
Thread execution task is still created after amount, causes excessive occupying system resources and causes system crash.
The task processing method based on thread pool as above is elaborated with reference to a specific application scenarios.Base
Run in the task processing method of thread pool in a computer equipment, specifically, as shown in Figure 7.
