Detailed Description
The invention is further illustrated by means of the following examples, which are not intended to limit the scope of the invention.
The distributed lock is used for guaranteeing the uniqueness and the security of the registration of the main service instance when a plurality of service instances are started simultaneously.
The redisson distributed lock can guarantee that only one instance can acquire the lock at a time. The service start initializes a certain number of clientIDs (client identifier) to store in redis (which is a memory), then each instance starts to remove the initialized clientIDs, and connects the mqtt server with the obtained clientIDs for receiving messages.
The service has a timed task to update the own occupied (used) clientID of each instance and store it in redis, identifying that this clientID is in use (used), and long-term non-updated clientIDs are considered unused by the instance.
In the prior art, the clientID is typically randomly generated, regularly generated, or a fixed clientID is employed. In either of the above ways, there is a problem that the clientIDs preempt each other, resulting in a multi-instance service start-up error, because the same clientID can only successfully connect to the mqtt server (interjacent, publishing the message) once.
For example, the service needs to start multiple instances, improving the mqtt data processing efficiency, 4 clientIDs, namely, clientID-1, clientID-2, clientID-3, and clientID-4 are initialized when the service starts to connect to the mqtt server, the clientIDs are stored in the redis, 2 instances A and B are started in total, the clientID is taken in the redis at A, B start, and if A takes the clientID-1 first and the mqtt server is successfully connected, and then B takes the clientID-1 again, but the instance A has succeeded in connecting to the mqtt by using the clientID-1, then the instance B always reports errors.
Based on the above problems, the embodiments of the present invention provide a communication control method, so as to avoid the problem of multi-instance service start-up error reporting caused by mutual preemption.
Fig. 1 is a flowchart of a communication control method according to an exemplary embodiment of the present invention, where the communication control method is applied to an electronic device, and the electronic device may include, but is not limited to, a computer, a server, a vehicle-mounted terminal, and the like. Referring to fig. 1, the communication control method includes the steps of:
step 101, in response to an execution request of the communication service, a plurality of instances of the communication service are started, so that the instances acquire the distributed lock.
The distributed lock may be, for example, a redisson distributed lock.
Step 102, controlling to obtain a first instance of the distributed lock, and obtaining a client identifier from a plurality of client identifiers of the electronic device, so that the first instance establishes communication connection with the external device by using the obtained client identifier.
The client identifiers are different from each other, and each client identifier is configured with an operation time for identifying whether the client identifier is used or not. The plurality of client identifiers may be randomly generated, regularly generated, or fixed client identifiers may be adopted.
In one embodiment, upon obtaining the client identification, the first instance releases the distributed lock to enable other instances than the first instance to obtain the distributed lock.
In one embodiment, the distributed lock is released if the duration of the first instance of obtaining the distributed lock reaches a duration threshold. By setting the duration threshold, it can be ensured that the first instance has acquired the client identity when releasing the distributed lock. The time length threshold can be set according to actual conditions.
Step 103, in the process of using the client identifier, updating the operation time of the used client identifier to the current time of the electronic device according to a preset period.
And updating the operation time of the used client identifier to the current time of the electronic equipment so as to identify whether the client identifier is used or not, and avoiding other instances from preempting the client identifier.
The preset period can be set according to actual requirements. The current time of day of the electronic device may be characterized by the current system time of day.
It will be appreciated that the smaller the preset period setting, the more frequently the operation time of the client identifier is updated, the more the client identifier can be characterized as being used. And in the process that the client identifier is used, the operation time of the client identifier is identified based on the current time of the electronic equipment, so that the situation that the client identifier is mistakenly not used by an instance and preempted by other instances due to overlong use time of the client identifier is avoided.
In one embodiment, a client identifier with a difference between the operation time and the current time of the electronic device being smaller than a preset period is written into the redis memory, and when the operation time is updated, the operation time of the client identifier in the redis memory is updated to the current time of the electronic device. The difference between the operation time and the current time of the electronic equipment is smaller than the client identifier of the preset period, which indicates that the client identifier is used by an instance, and the client identifier is written into the redis memory, so that the operation time of the client identifier is conveniently updated by the instance of the client identifier, and other instances are also convenient to distinguish whether the client identifier is used or not. And when the client identifier of which the difference between the operation time and the current time of the electronic equipment is not smaller than the preset period exists in the redis memory, removing the client identifier from the redis memory.
In one embodiment, the instance identified by the using client updates the operating time of the used client identification to the current time of the electronic device according to a preset period. The instance updates the operation time of the client identifier used by the instance, so that the timeliness and the accuracy of the update can be improved, and on the other hand, the instance or the script is not required to be additionally arranged, and the resource can be saved.
Step 104, controlling to obtain a second instance of the distributed lock, and obtaining a client identifier with a difference value between the operation time and the current time being greater than a preset period, so that the second instance establishes communication connection with external equipment by using the obtained client identifier.
If the difference between the operation time of the client identifier and the current time is larger than the preset period, the client identifier is not used by any instance, and the second instance can be controlled to acquire the client identifier, so that the preemption phenomenon with other instances can not occur.
In the embodiment of the invention, in the process of using the client identifier, the operation time of the client identifier is updated based on the current time of the electronic equipment, so that the situation that the client identifier is used for too long and is mistakenly not used by an instance is avoided, and the client identifier is preempted by other instances.
In one embodiment, in order to make the implementation logic simpler, the instance can conveniently obtain the unused client identifiers, the client identifiers can be divided, the client identifiers of the same type are divided into the same set, specifically, two sets are set, the first set contains all the client identifiers, and the second set contains the client identifiers with the difference between the operation time and the current time not greater than a preset period, namely the client identifiers used by the instance. When the second instance is controlled to acquire the client identifiers, the second instance is controlled to acquire the client identifiers which are not included in the second set from the first set, so that the second instance is prevented from comparing the operation time of each client identifier, unused and available client identifiers are determined, and the first instance only needs to find the used client identifiers in the first set and update the operation time of the used client identifiers, so that the operation is convenient.
In one embodiment, the first set is determined by acquiring a first instance of the distributed lock when the communication service is started, specifically, the acquired first instance of the distributed lock is responsible for initializing a preset number of client identifiers and putting the client identifiers into the first set, a key of the first set is the client identifier, a value is an operation time of the client identifier, the first set can be stored into a redis by using an hmset command, and other instances do not need the operation.
In one embodiment, the instance traverses the client identifier in the first set, extracts the value time (operation time) of the key and the value, compares the value time with the current time, considers the client identifier to be available when the difference between the operation time of the client identifier and the current time is larger than a preset period, puts the client identifier in the second set, and sets the distributed lock to be released within a certain time.
In one embodiment, a third set is set, the third set includes a client identifier having a difference between an operation time and a current time of the electronic device greater than a preset period, and when the second instance is controlled to acquire the client identifier, the second instance is controlled to acquire the client identifier from the third set.
In one embodiment, a first set, a second set and a third set are set at the same time, the first set contains all client identifiers, the second set contains the client identifiers of which the difference between the operation time and the current time is not greater than a preset period, the third set contains the client identifiers of which the difference between the operation time and the current time of the electronic device is greater than the preset period, the second instance is controlled to acquire the client identifiers which are not contained in the second set from the third set, and the first instance is controlled to update the operation time of the client identifiers in the second set.
Fig. 2 is a flowchart of another communication control method according to an exemplary embodiment of the present invention, in which an example a and an example B are taken as examples, and the example a performs client identifier initialization for illustration, and further illustrates communication control. Referring to fig. 2, the communication control method includes the steps of:
step 201, instance a acquires a redisson distributed lock.
Step 202, instance a determines whether a redisson distributed lock is acquired.
In step 202, if the determination result is yes, step 203 is executed; if the result is negative, return to step 201.
Step 203, the instance a initializes a predetermined number of client identifiers and puts them into the first set.
The key of the first set is the client identification, value is the time of operation, instance A uses the hmset command to store the first set into redis.
Step 204, the instance a obtains an operation time of the client identifier from the first set.
Step 205, the instance a determines whether the difference between the operation time of the client identifier and the current time of the electronic device is greater than a difference threshold.
In step 205, if the determination result is yes, it is indicated that the client identifier is available or not occupied by other instances, and step 206 is performed; if the result is no, the step 204 is returned to acquire the operation time of the client identifier again. The re-acquisition of the client identification may take the form of a loop traversal.
Step 206, instance a places the client identification into a second set and establishes a communication connection with an external device using the client identification.
The second set includes client identifiers having a difference between the operation time and the current time not greater than a preset period, i.e., client identifiers occupied by the instance.
In step 207, in the process that the client identifier is used, the instance a updates the operation time of the used client identifier to the current time of the electronic device according to the preset period.
The instance A updates the operation time of the client identifier in the second set according to the preset period, and updates the operation time of the client identifier in the second set to the first set, so that the operation time of the client identifier in the second set is synchronous with the operation time of the corresponding client identifier in the first set.
Step 208, instance a releases the redisson distributed lock to enable other instances to acquire the redisson distributed lock.
Step 201', instance B acquires a redisson distributed lock.
Step 202', instance B determines whether a redisson distributed lock was acquired.
In step 202', if the determination result is yes, step 203' is executed; if the determination is negative, the process returns to step 201'.
Step 203', instance B loops the first set to sequentially obtain the operation time of one client identifier.
Step 204', instance B determines whether the client identification exists in the second set.
In step 204', if the determination result is no, step 205' is performed; if the determination result is yes, the step 203' is returned to acquire the operation time of one client identifier again. The re-acquisition of the client identification may take the form of a loop traversal.
Step 205', instance B creates a third set, in which the key is the currently acquired client identifier and the value is the operation time of the client identifier.
Step 206', instance B loops over the first set, storing the third set use hmset command into redis.
The hmset command may update only the value of the change, which does not update.
It should be noted that, each instance may start a timing task, execute steps 203 'to 206', specifically, loop the first set, then determine that the circulated client identifier is not in the second set, create a third set if the circulated client identifier exists, where the key of the third set is the client identifier clientID, the value is the operation time of the client identifier, the first set is circulated, and store the command of using hmset by the third set into redis.
Through the steps, only one instance can be ensured to initialize and distribute the client identifiers at the same time, the situation that the client identifiers are preempted by each other can not occur when multiple instances are started, and the client identifiers can be accurately known.
If so, the instance B may also obtain a client identifier from the first set, which is not included in the second set, and use the client identifier to establish a communication connection with the external device.
The invention also provides an embodiment of the communication control device corresponding to the embodiment of the communication control method.
