It should be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the application described herein may be used. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
According to an embodiment of the present application, a notification transmission method is provided. Fig. 1 is a flowchart of a notification transmission method according to an embodiment of the present application, and as shown in fig. 1, the method includes steps S102 to S106 as follows:
step S102, obtaining the notification to be sent from the message queue, wherein all the notifications to be sent are added to the message queue in advance.
The to-be-sent notification in the embodiments of the present application may be a mail, a short message, qq information, a wechat information, and the like, and all the embodiments of the present application are described below with a mail to be sent as an example.
According to the embodiment of the application, when the notification needs to be sent, the notification to be sent is added to the message queue in advance for queuing. Specifically, taking an example that a website data analysis system sends a periodic report to a user at regular time, when the website data analysis system needs to send the periodic report to the user, querying data in a database, then outputting the data to a report template to generate a report, and generating a mail to be sent according to the report and adding the mail to be sent to a message queue; when the report forms need to be sent to a plurality of users at the same time, the report forms corresponding to the users are respectively generated, a plurality of mails to be sent are respectively generated according to the report forms, and the mails to be sent are all added into a message queue for queuing.
According to the embodiment of the application, after the to-be-sent notifications are all added to the message queue in advance, all the to-be-sent notifications are sequentially acquired from the message queue and sent.
Step S104, judging whether the number of sending threads is less than the maximum concurrency degree, wherein the sending threads are threads for executing notification sending operation.
The maximum concurrency degree in the embodiment of the present application refers to the maximum number of notifications that can be sent in parallel, and optionally, the value of the maximum concurrency degree may be set according to the concurrency degree of the notifications sent by the notification server, for example, when sending a mail, the concurrency degree of the mail sent by the mail server is 10, the value of the maximum concurrency degree may be set to 10, so that the mail sender may be utilized maximally, and the mail sending efficiency may be improved.
Specifically, the number of sending threads may be counted by setting a counter, or an empty sending thread set may be created in advance, and the number of elements in the sending thread set is limited to the maximum concurrency, after a sending thread is created each time, the sending thread is added to the sending thread set, and after the sending thread completes notification sending, the sending thread is deleted from the sending thread set, so that the number of the current sending threads may be obtained quickly by counting the number of sending threads in the sending thread set.
According to the embodiment of the application, whether a new sending thread can be created to send the notification is determined by judging whether the number of the sending threads reaches the maximum concurrency degree, so that the notification sending blockage caused by excessive notifications sent in parallel can be avoided.
And step S106, when the number of the sending threads is judged to be less than the maximum concurrency degree, a new sending thread is created, and the notice to be sent is sent through the new sending thread.
Specifically, taking sending a mail as an example for explanation, when it is determined that the number of sending threads is less than the maximum concurrency degree, it is determined that the current mail server is not in the maximum load state, at this time, a new sending thread may be created, and the mail to be sent, which is currently acquired from the message queue, is sent out through the new sending thread, and when it is determined that the number of sending threads is not less than the maximum concurrency degree, it is determined that the current mail server is in the maximum load state, and in order to avoid operating the mail server to crash, at this time, a new sending thread should not be created to send the mail. Optionally, when it is determined that the number of sending threads is not less than the maximum concurrency degree, the method further includes: and waiting for a first preset time, and judging whether the number of the sending threads is less than the maximum concurrency degree again.
The sending thread automatically releases the resources when the notification sending is completed, so that the number of the sending threads is updated in real time, when the number of the sending threads is judged not to be smaller than the maximum concurrency degree at present, the sending thread can wait for a first preset time (for example, wait for 5 seconds), judge whether the number of the sending threads is smaller than the maximum concurrency degree again, and repeat the above process until the number of the sending threads is smaller than the maximum concurrency degree.
The method comprises the steps that the to-be-sent notifications are obtained from a message queue, wherein all the to-be-sent notifications are added to the message queue in advance; judging whether the number of sending threads is smaller than the maximum concurrency degree or not, wherein the sending threads are threads for executing notification sending operation; and when the number of the sending threads is judged to be smaller than the maximum concurrency degree, a new sending thread is created, and the notification to be sent is sent through the new sending thread.
Preferably, in order to avoid the problem of missed notification due to abnormal notification transmission, when the number of the transmission threads is determined to be less than the maximum concurrency degree, a new transmission thread is created, and after the notification to be sent is sent through the new transmission thread, the method further includes: detecting whether the notification to be sent is abnormal or not; and when the abnormity of the notification to be sent is detected, the notification to be sent is added to the message queue again.
Because each time of sending the notification is not necessarily successful, in order to avoid the problem of missed sending of the notification due to abnormal sending of the notification, in the embodiment of the application, after the notification is sent through the sending thread, whether the sending of the notification to be sent is abnormal is detected, for example, whether the notification to be sent is successfully sent to the recipient address is detected, when the sending of the notification to be sent is detected to be abnormal, the notification to be sent is added to the message queue again to be queued again for sending again, and the sending thread corresponding to the notification to be sent with abnormal sending is deleted. It should be noted that, when it is detected that the notification to be sent is successfully sent, the sending thread corresponding to the notification to be sent may be directly released.
According to the embodiment of the application, the notification to be sent can be added into the sending queue again to be sent again when the notification to be sent is abnormal every time, so that the problem of notification missing caused by abnormal notification sending can be avoided.
Preferably, in order to avoid the problem of missed notification due to abnormal notification transmission, when the number of the transmission threads is determined to be less than the maximum concurrency degree, a new transmission thread is created, and after the notification to be sent is sent through the new transmission thread, the method further includes: detecting whether the notification to be sent is abnormal or not; when the abnormity of the notification to be sent is detected, judging whether the sending times of the notification to be sent reaches a preset value; when the sending times of the to-be-sent notification are judged to be not equal to a preset value, adding 1 to the sending times of the to-be-sent notification, and adding the to-be-sent notification to the message queue again; and when the sending times of the to-be-sent notification is judged to reach a preset value, recording the to-be-sent notification, and outputting abnormal information.
Due to the existence of some notifications, even if the notification is sent for multiple times or the notification fails to be sent, for example, the sending address is wrong, and at this time, endless repeated sending cannot solve the problem, but occupies the resources of the notification server, and affects the efficiency of the notification server in sending the notification. In the embodiment of the application, the number of times of sending the notification is limited, when it is detected that there is an abnormality in sending the notification to be sent, it is first determined whether the number of times of sending the notification to be sent reaches a preset value, for example, the preset value is set to 3, and if the number of times of sending the notification to be sent does not reach the preset value, the notification to be sent is added to the message queue again, and the number of times of sending the notification to be sent is added by 1; if the sending times of the to-be-sent notification reach a preset value, the to-be-sent notification is recorded, and abnormal information is output, so that an operator can analyze the reason for the failure of sending the to-be-sent notification according to the abnormal information, and can send the to-be-sent notification manually, on one hand, the to-be-sent notification which is sent abnormally can be prevented from occupying notification server resources for a long time, and on the other hand, the problem of notification missing can be completely avoided.
It should be noted that, in the embodiment of the present application, when there is an abnormality in each transmission of the to-be-transmitted notification, the abnormality information may be recorded, for example, in a log, and the abnormality information of each time is added to the abnormality set corresponding to the to-be-transmitted notification, and when the number of times of transmission of the to-be-transmitted notification reaches a preset value, all the abnormalities in the abnormality set are combined and output.
Preferably, before acquiring the notification to be sent from the message queue, the method further includes: detecting the state of an operation switch, wherein the state of the operation switch comprises an opening state and a closing state, the opening state is used for indicating to execute notification sending operation, and the closing state is used for indicating to stop executing the notification sending operation; and when the operation switch is detected to be in an on state, judging whether the message queue is empty, wherein when the message queue is judged not to be empty, obtaining a notification to be sent from the message queue, and when the message queue is judged to be empty, waiting for a second preset time, and judging whether the message queue is empty again.
In order to facilitate control of sending of the notification, an operation switch is provided in the embodiment of the present application, and the sending operation of the notification is executed only when the operation switch is in an on state.
In the embodiment of the application, before obtaining a notification to be sent from a message queue and sending the notification, the state of an operation switch is detected, when the operation switch is detected to be in an on state, the notification can be sent at the moment, and whether the message queue is empty is continuously judged, wherein when the message queue is judged not to be empty, the notification to be sent is obtained from the message queue, and when the message queue is judged to be empty, a second preset time, for example, 10 seconds, is waited to judge whether the message queue is empty again; when the operation switch is detected to be in the off state, the operation switch may be turned on to send a notification, or may be turned off directly. It should be noted that the system may be configured to continuously add the notification to be sent to the message queue within a preset time period, so that when the operation switch is in the on state, the system has not yet added the notification to be sent to the message queue, that is, the message queue is empty, and at this time, it may wait for a second preset time to re-determine whether the message queue is empty.
Preferably, after all the notifications to be sent are added to the message queue, the method further comprises: judging whether the message queue is empty; and setting the state of the operation switch to be in a closing state when the message queue is judged to be empty.
Specifically, after all notifications to be sent are added to the message queue, the embodiment of the present application determines whether the message queue is empty to finish sending the notifications, specifically, when it is determined that the message queue is not empty, the notifications to be sent are sequentially taken from the message queue to be sent, and when it is determined that the message queue is not empty, that is, all notifications to be sent that need to be sent in the current time period are sent, at this time, the state of the operation switch may be set to be in an off state to finish sending the notifications, so that idle running of the program can be avoided, and system resources are occupied.
Fig. 2 is a flowchart of a notification transmission method according to another embodiment of the present application, as shown in fig. 2, the method includes the following steps:
step S201, the operation switch is turned on.
In step S202, a set of sending threads is created.
The number of elements in the set of send threads is the number specified by the maximum concurrency.
In the embodiment of the present application, after the sending thread set is created in step S202, circular scanning is started by the background thread, and the scanning steps of each time are as follows, step S203 to step S219:
step S203, determine whether the operation switch is on.
I.e. whether the switch is allowed to be in an on state. And executing the step S204 when the permission switch is judged to be opened, otherwise, ending.
Step S204, judge whether the message queue is empty.
Specifically, in the embodiment of the present application, a notification entity may be predefined, where the notification entity includes notification information, sending times and an exception set, where the notification information includes information such as a sending address and a notification (that is, specific sending content), the sending times refers to the sending times of the notification to be sent, and the exception set is used to record an exception of the notification to be sent. When the notification needs to be sent, the notification entity is added to the message queue for queuing.
When the message queue is judged to be empty, the embodiment of the application shows that no notification entity needs to be sent in the current message queue, and step S205 is executed; when the message queue is determined not to be empty, it indicates that there is a notification entity in the current message queue to send, and step S206 is executed.
Step S205, wait 10 seconds.
In step S206, a notification entity is retrieved.
Step S207, determine whether the number of sending threads in the sending thread set is less than the maximum concurrency.
Specifically, when it is determined that the number of sending threads in the sending thread set is not less than the maximum concurrency degree, step S208 is executed, that is, the step S waits for 5 seconds, and it is determined again whether the number of sending threads in the sending thread set is less than the maximum concurrency degree; when it is determined that the number of sending threads in the sending thread set is less than the maximum concurrency degree, step S209 is performed.
Step S208, wait 5 seconds.
In step S209, a new transmission thread is created.
Step S210, add a new sending thread to the sending thread set.
Step S211, a notification is sent.
I.e. to start sending notifications according to the notification information.
In step S212, it is determined whether there is an abnormality.
That is, whether or not there is an abnormality in the transmission notification, for example, a transmission failure or the like is determined. When it is determined that there is a transmission abnormality, step S213 is executed, otherwise step S219 is executed.
In step S213, it is determined whether the number of transmission times reaches the maximum number of transmission times.
When it is determined that the transmission count has reached the maximum transmission count, step S214 is executed, and when it is determined that the transmission count has not reached the maximum transmission count, step S216 is executed.
Step S214, combining the exceptions in the exception set of the notification entity into a new exception and throwing the new exception.
In step S215, an abnormality is recorded in the log.
In step S216, the number of transmissions is increased by 1.
Step S217, add the exception to the exception set of the notification entity.
Step S218, the notification entity is added to the message queue again.
In step S219, the sending thread is deleted from the sending thread set.
That is, after the transmission is completed, the transmitting thread is deleted from the thread set.
It should be noted that, in the embodiment of the present application, when the background thread performs circular scanning, it is circularly determined whether the message queue is empty, when it is determined that the message queue is empty, the operation switch is turned off, and after the subsequent background scanning thread performs one cycle, it is checked that the operation switch is turned off, and the scanning thread exits the cycle.
Preferably, in order to facilitate the program call, the embodiment of the present application may define a notification manager in advance, where the following members are defined: a notification context, the context containing common configurations needed to send notifications; maximum degree of concurrency; notifying the entity queue; sending a thread set; whether to operate the switch; and sending a notification method, wherein the parameters are notification entities, and the method adds the notification entities into a notification entity queue for queuing.
From the above description, it can be seen that the concurrency of mail sending of a general mail server is very low, which is far from meeting the requirement, and high concurrency of mails is needed in many places.
It should be noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowcharts, in some cases, the steps illustrated or described may be performed in an order different than presented herein.
