As it is shown in figure 1, embodiments provide a kind of method for allocating tasks, the method may comprise steps of:
Step 101: according to classification of task number, builds at least two message queue；
Step 102: configuration task classification and the corresponding relation of message queue；
Step 103: task Producer often produces a task, determines the priority of this task；
Step 104: when the priority determining this task is higher than and sets level, this task is assigned to queuing number minimum
In message queue；When the priority determining this task is not higher than described setting level, determine the classification belonging to this task；According to this
Classification belonging to task and described corresponding relation, be assigned to this task in corresponding message queue；
Step 105: in scheduling process each message queue in described at least two message queue, dispatch phase respectively
Answer the task of number, and the task of scheduling is assigned in common queue.
According to the invention described above embodiment, by the corresponding relation of configuration task classification with message queue, with by priority
The task of not higher than setting level is assigned in corresponding message queue, and the number so queued up in each message queue is different, because of
This, in the task priority that task Producer produces higher than when setting level, can divide this priority higher than the task of setting level
It is fitted on the message queue that queuing number is minimum, it is ensured that this priority can be preferably dispatched to general higher than the task of setting level
In logical queue, to be consumed in time by subsystem.
In an embodiment of the invention, when the task priority that task Producer produces is higher than setting level, the most really
Whether this at least two message queue fixed includes null message queue, if including null message queue, by priority higher than setting level
Task be assigned in this null message queue；If not including null message queue, it is determined that described at least two message queue is arranged
The message queue that team's number is minimum, is assigned to, higher than the task of setting level, the message queue that this queuing number is minimum by this priority
In.
Wherein, the queuing situation in each message queue can be monitored by monitoring unit, and by monitor each
The queuing situation of message queue is synchronized in data base, and task Producer can be by each message queue in reading database
Queuing situation determines the message queue that queuing number is minimum.
In an embodiment of the invention, owing to being configured with corresponding relation between message queue and classification of task, task is raw
Product person often produces a task, when this task priority not higher than sets level, can be assigned to this task disappear accordingly
In breath queue, therefore, message queue that this queuing number is minimum is if not null message queue, then this minimum disappearing of queuing number
Breath queue is configured with the classification of task with it with corresponding relation, and higher than the task of setting level, this priority is being assigned to this row
After in team's minimum message queue of number, can be that the classification of task that the minimum message queue of this queuing number is corresponding is joined again
Put the message queue of correspondence, so that the task of this classification that subsequent production goes out be not assigned to the message team that this queuing number is minimum
In row.
In an embodiment of the invention, in order to priority be consumed in time higher than the task of setting level, process is dispatched
May include that production thread and at least two consuming thread；Wherein, described at least two consuming thread disappears with described at least two
Breath queue one_to_one corresponding；
Farther include: monitor the priority included in each message queue task higher than described setting level
Number, and monitored results is sent to scheduling process；
Farther include: described scheduling process receives monitored results, and is that each consuming thread is joined according to monitored results
Put consumption quantity；
In described scheduling process each message queue in described at least two message queue, corresponding of scheduling respectively
The task of number, takes out from corresponding message queue according to the consumption quantity of configuration including: each consuming thread and consumes number accordingly
The task of amount, and be sent to the task of taking-up produce thread；Produce thread to send out receiving described at least two consuming thread
After sending of task, receiving of task is sent to common queue.
Wherein it is possible to the priority included according to each message queue is higher than setting the task number of level, for accordingly
Consuming thread distribution directly proportional consumption quantity, such as, message queue 0 includes that the priority of 10% is higher than setting appointing of level
Business, message queue 1 includes that the priority of 20%, higher than the task of setting level, does not includes in message queue 2-message queue 19
Priority higher than set level task, then can be consuming process 0 configure consumption quantity be 20, join for consuming process 1
The consumption quantity put is 30, and all configuring consumption quantity for consuming process 2-consuming process 19 is 10.
In an embodiment of the invention, in order to prevent consuming thread from taking out task in corresponding message queue always, with
And be sent to produce thread by the task of taking-up, dormancy awakening mechanism can be set: each consuming thread is by appointing of taking out
After business is sent to produce thread, enters resting state, when the described whole dormancy of at least two consuming thread, wake up described life up

Journey, described production thread enters resting state.Such that it is able to the task of realizing one batch of next batch processes, and reach to follow
The purpose that ring performs.
In an embodiment of the invention, in order to ensure can be consumed in time higher than the task of setting level in priority,
The number more than the number of classification of task 1 of the described at least two message queue of structure can be made；So, null message queue is permissible
For special priority of placing higher than the task of setting level.
In an embodiment of the invention, when monitoring described at least two message queue and including null message queue,
The corresponding relation of this null message queue of configuration with classification of task can be deleted, so that this null message queue can be placed excellent
First level is higher than the task of setting level.
According to above-described embodiment, below in conjunction with concrete accompanying drawing, the embodiment of the present invention is described in detail.
As in figure 2 it is shown, embodiments provide a kind of method for allocating tasks, the method may comprise steps of:
Step 201: determine the number of classification of task.
In the present embodiment, as a example by this task distribution system is used for realizing web crawlers, this classification of task is said
Bright.When carrying out web crawlers, need to crawl the data produced on each website, therefore, it can to produce on each website
Task as a classification of task.Such as, website A correspondence classification of task A, website B correspondence classification of task B.
The present embodiment can illustrate as a example by the number of classification of task is 19.
Step 202: build at least two message queue according to the number of classification of task, and configure message queue and divide with task
The corresponding relation of class.
The number of at least two message queue built can determine according to real needs, if the message queue built
Number is more than the number of classification of task, then can be the more multiple message queue of classification configurations of task, less for task
One message queue of classification configurations.If the number of the message queue built is less than the number of classification of task, multiple can be configured
The corresponding message queue of business classification.
In an embodiment of the invention, the number that can build at least two message queue is more than the number of classification of task
1.Such as, 20 message queues are built.
By classification of task and message queue one_to_one corresponding and classification of task one to one is corresponding with message queue configuration
Relation, to be assigned to classify with it in message queue with corresponding relation by the task of production.
Such as, classification of task A is configured to corresponding relation with message queue 0, classification of task B is configured with message queue 1
For corresponding relation ....
Refer to Fig. 3, for combining the task distribution schematic diagram that task allocation apparatus illustrates.In this Fig. 3, message team
The number of row includes 20.
Step 203: this corresponding relation of configuration is stored in data base, and is sent to each task Producer.
Step 204: monitoring unit monitors the queuing situation of each message queue, and queuing situation is synchronized to data base
In, when monitoring includes null message queue, the corresponding relation of this null message queue of configuration with classification of task is deleted, and by sky
The mark of message queue is sent to each task Producer.
Wherein, the queuing situation of message queue can include the task number queued up in message queue.
Step 205: produce a task at task Producer, determine the priority of this task.
In the present embodiment, priority can be set previously according to the urgency level of task, it may for example comprise 1-7 preferential
Level, 1 is lowest priority, and 7 is limit priority.Producing of task all can carry respective priority rank.
Step 206: if the priority of this task is higher than setting level, then this task is assigned to the message that queuing number is minimum
In queue；If the priority of this task not higher than sets level, it is determined that the classification belonging to this task, and this task is assigned to
Its affiliated classification has in the message queue of corresponding relation.
In the present embodiment, one can be arranged and set level, such as, 4 grades, the priority task higher than 4 grades is defined as
It is badly in need of being consumed of task.
Wherein, task Producer first determines whether to include null message queue, if including null message queue, the most directly should
Priority is assigned in this null message queue higher than the task of setting level.And configure the corresponding relation of this null message queue, should
Null message queue is as being specifically designed to the message queue placing priority higher than the task of setting level.
In subsequent process, task Producer produces making new advances of task, when the priority of this task is higher than setting level, and will
This task is assigned directly to this and is specifically designed in the message queue placing high-priority task.If this is used for putting in subsequent process
Set high queuing number in the message queue of priority tasks more, then priority can be placed into higher than the task of setting level
In the message queue that other queuing numbers are minimum.
If not including null message queue, then, the queuing situation of each message queue in task Producer reading database,
Determine the message queue that current queuing number is minimum, this priority is assigned to this queuing number higher than the task of setting level minimum
Message queue in.And after priority is assigned in the message queue that queuing number is minimum higher than the task of setting level,
The corresponding relation of message queue minimum for number of queuing up with classification of task is deleted.
Step 207: the priority that each message queue of storage in data base is included by monitoring unit is higher than setting level
The number of task, be sent to scheduling process.
In the present embodiment, in order to be further ensured that priority be higher than set level task preferentially consumed, monitoring unit
Can monitor which message queue is priority be all assigned to higher than the task of setting level, and monitored results is synchronized to data
In storehouse, and before scheduling process takes task from message queue, this monitored results is sent to scheduling process so that dispatch into
Journey takes task according to the monitored results received from each message queue.
Step 208: scheduling process builds consuming thread, the number of consuming thread and message team according to the number of message queue
The number of row is identical, wherein, and consuming thread and message queue one_to_one corresponding, and close according to consuming thread is corresponding with message queue
System, configures consumption quantity for each consuming thread.
Refer in Fig. 3, the number of this consuming thread is 20, and each consuming thread is relative with corresponding message queue
Should.
Wherein it is possible to the priority included according to each message queue is higher than setting the task number of level, for accordingly
Consuming thread distribution directly proportional consumption quantity, such as, message queue 0 includes that the priority of 10% is higher than setting appointing of level
Business, message queue 1 includes that the priority of 20%, higher than the task of setting level, does not includes in message queue 2-message queue 19
Priority higher than set level task, then can be consuming process 0 configure consumption quantity be 20, join for consuming process 1
The consumption quantity put is 30, and all configuring consumption quantity for consuming process 2-consuming process 19 is 10.
Step 209: each consuming thread takes out the task of corresponding consumption quantity from corresponding message queue, and
The task of taking-up is sent to the production thread of scheduling process, after sending successfully, enters resting state.
In the present embodiment, each consuming thread is after being sent to the task of taking-up produce thread, in order to prevent again
Secondary from message queue, take task, resting state can be entered.
Step 210: when all consuming thread all enter resting state, wake up production thread up.
Step 211: produce thread and all tasks received are sent in common queue, and wake up each consumption line up
Journey, produces thread and enters resting state.
Above, it is ensured that scheduling process, according to the priority case of task, is taken out task from message queue, and will be taken
Going out of task is sent along in common queue, carries out consumption for other subsystems, thus ensure that priority is higher than and set
Thinking of deciding grade and level is preferentially consumed.
