Abstract
The invention discloses a lock-based thread management method. The lock-based thread management method includes: S100, acquiring number information of distributed lock resources when receiving lock resource acquisition requests; S200, judging whether the number of the distributed lock resources is larger than a preset threshold value or not according to the number information of the distributed lock resources, if yes, repeatedly executing the step S200, and if not, executing the next step; S300, receiving the lock resource acquisition requests, and distributing lock resources to threads initiating the lock resource acquisition requests. By the lock-based thread management method and the lock-based thread management device, the lock resources can be monitored, and the problem of excessive system processing resource occupation caused by continuous monitoring of lock behaviors can be avoided.
Description
Technical field
The present invention relates to field, more particularly to a kind of thread management method and device based on lock.
Background technology
Java server program will typically provide the service ability of high concurrent, and multithreading causes the concurrency for servicing to carry significantly
Rise.In order to solve the problems, such as resource access conflict, lock be it is a kind of commonly with technology, i.e., multiple threads access one simultaneously
During resource, because there is particularity in some resources, once can only be by a thread accesses, such as：Write behaviour is carried out to file
Make, if multiple threads write the problem that file content can be caused chaotic simultaneously.Therefore, write operation is carried out to file, it is necessary to
One lock of setting, only getting the thread of lock could write to file.In reality, there are many places to be required for using
To lock.
Now lock is the technology point of comparative maturity in Java, but nonetheless, during actual use, is still held very much
Easily go wrong, such as certain thread takes always certain resource, does not discharge always, other threads can always wait obstruction.
Because the request of client is constantly produced, thread also can accordingly increase, if resource cannot discharge always, service end meeting quickly
Substantial amounts of thread is produced, so that the resource exhaustion of server, loses service ability.
The content of the invention
To solve above-mentioned technical problem, the present invention provides a kind of thread management method based on lock and device, can be to lock
Resource is monitored, and caused by can avoiding the occurrence of because continuously carrying out lock behavior monitoring asking for system processing resources is excessively taken
Topic.
The technical scheme that the present invention is provided is as follows：
The invention discloses a kind of thread management method based on lock, including step：S100, when receive obtain lock resource
During request, acquisition distributes lock resource quantity information；Distribute lock resource quantity information described in S200, basis and judge allocated
Whether lock resource quantity is more than predetermined threshold value；If so, step S200 is repeated；Otherwise perform next step；S300, acceptance are described
Lock request is obtained, is to initiate to obtain the thread distribution lock resource of lock resource request.
It is further preferred that also including step before step S100：S010, the setting predetermined threshold value；It is described pre-
If threshold value is the maximum lock resource quantity that user is arranged；S020, setting preset duration；The preset duration is what user was arranged
The most long lock resource occupied time.
Invention additionally discloses another kind of thread management method based on lock, including step：S100, when receive obtain lock money
When source is asked, acquisition distributes lock resource quantity information；Distribute lock resource quantity information described in S200, basis to judge to distribute
Lock resource quantity whether be more than predetermined threshold value；If so, step S200 is repeated；Otherwise perform next step；S300, receive institute
Acquisition lock request is stated, is to initiate to obtain the thread distribution lock resource of lock resource request；S400, the shape for monitoring allocated lock resource
State；S500, judge whether allocated lock resource occupied time exceedes the preset duration；If so, then forcible aborting is locked
Resource.
It is further preferred that also including step：S600, when have lock resource discharge when, update described in distributed lock number of resources
Amount information.
Invention additionally discloses a kind of thread management device based on lock, including：Acquisition module, for working as acquisition lock is received
During resource request, acquisition distributes lock resource quantity information；Quantity judge module, for having distributed lock resource quantity according to
Whether information judges allocated lock resource quantity more than predetermined threshold value；Distribute module, for when allocated lock resource quantity
During more than predetermined threshold value, receive the thread distribution lock resource for obtaining lock resource request, being initiation obtains lock resource request.
It is further preferred that also including：Setup module, for arranging the predetermined threshold value；And setting preset duration；Institute
State the maximum lock resource quantity that predetermined threshold value is that user is arranged；The preset duration is the most long lock resource quilt that user is arranged
The time of occupancy.
Invention additionally discloses a kind of thread management device based on lock, including：Acquisition module, for working as acquisition lock is received
During resource request, acquisition distributes lock resource quantity information；Quantity judge module, for having distributed lock resource quantity according to
Whether information judges allocated lock resource quantity more than predetermined threshold value；Distribute module, for when allocated lock resource quantity
During more than predetermined threshold value, receive the thread distribution lock resource for obtaining lock resource request, being initiation obtains lock resource request；Prison
Control module, for monitoring the state of allocated lock resource；Duration judge module, it is occupied for judging allocated lock resource
Time whether exceed the preset duration；Release module, judges that the allocated lock resource occupied time exceedes for working as
During the preset duration, forcible aborting lock resource.
It is further preferred that also including：Update module, for when there is lock resource to discharge, distributing lock money described in renewal
Source quantity information.
Compared with prior art, all of thread lock is obtained using factory mode in the present invention, by an object unification point
With lock resource, so public to be assigned with how many locks, each lock is consumed and how long can be monitored.The present invention to distributing
Lock quantity arrange predetermined threshold value, if the quantity for monitoring currently allocated lock has reached predetermined threshold value, no longer receive
New request, excessively takes the problem of system processing resources, together caused by can avoiding the occurrence of because continuously carrying out lock behavior monitoring
When, when the time that certain thread takes lock resource reaches preset duration, meeting forcible aborting lock resource of the invention reduces lock money
The waste in source, is system reasonable arrangement resource.
