In the embodiment of the invention, when the task is actually scheduled, because the execution cycle of part of the tasks is unclear, the tasks need to be repeatedly adjusted according to the actual operation condition of the project, and the project needs to be restarted after each adjustment, so that the tasks cannot be visually arranged according to the actual requirement to provide continuous services. Therefore, in order to implement the visual arrangement of the tasks, the task execution flow chart can be drawn according to the logic sequence of the target task execution through the visual graphical interface, and the configuration parameters corresponding to the tasks need to be determined for each target task, and the configuration parameters of the target tasks are configured correspondingly in the task plan execution table. The task execution schedule configured by the user is a target task execution schedule meeting the requirements of the user. Based on the configured target task execution schedule, the user can draw a task execution flow chart on a visual graphical interface according to the task execution logic of the user and the logic relation among the target tasks. Meanwhile, for the task nodes with the circular traversal, the tasks can be written into a task with a fragment type, the executors can execute the tasks in a parallel mode after recognition, and the traversed elements are collected and then executed in a fragment mode.

and according to the at least one piece of identification information, performing exception processing aiming at the target task execution flow corresponding to the exception state.

In the embodiment of the invention, because the existing task scheduling system cannot check the running state of the task in real time on line, in order to check and monitor the running state of the task in real time, the running state of each target task can be determined according to the execution result of the task execution flow, and the identification information for representing the running state of each target task is set for each target task according to the execution result of each target task, so that a user can check the corresponding identification information through a visual graphical interface to monitor the running condition of the task in real time, visualize the running state of the task in real time, and monitor the task on the basis, thereby finding the defects of the task in time to improve and improving the working efficiency.

In order to add a new task execution flow, in an embodiment of the present invention, the foregoing embodiment further includes:

when a new task execution flow is needed, determining at least one new task execution flow, wherein the at least one new task execution flow comprises at least one new task, and the at least one new task is not included in the task execution flow chart;

In order to implement multi-process collaboration, in an embodiment of the present invention, the foregoing embodiment further includes:

when at least two task execution flowcharts exist, aiming at a first task execution flowchart and a second task execution flowchart in the at least two task execution flowcharts, determining whether the first task execution flowchart and the second task execution flowchart have an association relation;

if the first task execution flow chart and the second task execution flow chart are determined to be in the association relationship, executing the following steps:

s1: determining a target first task and a target second task which have an association relationship, wherein the target first task is contained in a first task execution flow chart, and the target second task is contained in a second task execution flow chart;

s2: determining whether the target first task needs to be executed first and the target second task needs to be executed after the target first task is executed, if yes, executing step S3, otherwise, executing step S5;

In the embodiment of the invention, after the tasks are visually arranged, a plurality of task execution flow charts with mutual association can support the function of multi-flow cooperation. When the execution sequence between two task execution flowcharts on a certain node needs to be defined in time, a pause identifier may be added to the task execution flowcharts. When the progress and the execution result of the target task in the other task execution flowchart need to be waited, the current target task corresponding to the current task execution flowchart may mark the current execution state through the pause identifier, then wait for the result of the other process, and after the execution result of the other process is obtained, the current process may resume running.

In order to determine the target task execution schedule, in an embodiment of the present invention, the configuration parameters in the foregoing embodiment include: task configuration parameters and condition trigger configuration parameters;

step 101 in the foregoing embodiment determines at least one configuration parameter in the task execution schedule, which may be specifically implemented as follows:

determining at least one target task configuration parameter and at least one target condition trigger configuration parameter in a task execution schedule, wherein the target condition configuration parameter comprises: year, month, day, hour, minute, second, week;

step 102 in the foregoing embodiment configures at least one configuration parameter in the task execution schedule to generate the target task execution schedule, which may be specifically implemented by the following means:

configuring at least one target task configuration parameter and at least one target condition configuration parameter in a task execution schedule;

the task execution process corresponding to the task execution flowchart executed in step 105 in the foregoing embodiment may be specifically implemented by the following processes:

determining whether a trigger condition corresponding to the condition trigger information is met;

and executing the task execution flow corresponding to the task execution flow chart when the triggering condition corresponding to the condition triggering information is determined to be met.

In the embodiment of the present invention, since a parameter corresponding to each target task needs to be configured to generate a target execution schedule, and each target task is necessarily triggered and executed under a certain condition, in addition to configuring a basic task configuration parameter, a condition trigger configuration parameter corresponding to a trigger condition needs to be configured, for example, a specific trigger period may be input on a visual graphical interface for simple triggering, a delay time may be input for triggering, or a Cron expression may be input for triggering. In the process of triggering the Cron expression, a user can click a mouse to select information such as year, month, day, hour, minute, second, week and the like required by task triggering, so that the Cron expression can be automatically generated, and meanwhile, the execution of the flow corresponding to the target task can be triggered only when the triggering condition corresponding to the condition triggering information is met, so that whether the triggering condition corresponding to the condition triggering information is met needs to be determined, and when the triggering condition corresponding to the condition triggering information is determined to be met, the task execution flow corresponding to the task execution flow chart is automatically executed.

In an embodiment of the invention, the timing task is an important scene in software development, and plays an important service for both user and service providers. Initially only the system is required to perform a specific job at the scheduled point in time, (which may be disposable or periodic), such a timing task is simple to implement and can also meet most of the requirements. With the iterative development of software, the use scenes of timing tasks are continuously rich, the requirements are more and more, and the task triggering becomes more and more complex, so that dynamic task management is required, for example, some tasks need to be executed in a chain manner, the execution of the following tasks depends on the execution result of the former tasks, and the timing tasks need to support task arrangement. Therefore, the invention can be applied to a dynamic timing task management system in a complex situation and has important significance for good development of project ecology.

The Quartz-based framework is a set of open-source lightweight task scheduling framework developed based on Java, provides a powerful and flexible scheduling mechanism, simultaneously reserves the simplicity of a using method, and can be used for basic timing tasks such as fixed point triggering, periodic triggering and the like through simple configuration. However, when the method is used in a complex production environment, the method has the characteristics of ensuring good operability and processing complex tasks, such as processing of chain tasks and parallel tasks, and simultaneously ensuring easy expandability so as to adapt to the increasing demands in the production environment. The invention can build a set of visual task management system which is easy to operate and expand based on Quartz. The system can integrate Quartz and Web, and dispatch and management of tasks are performed by using visual operation, so that an operator only needs to pay attention to the logic configuration of the dispatching of the tasks and does not need to pay attention to the specific implementation of the timing tasks, and the requirement of the operator on professional knowledge is reduced to the maximum extent.

As shown in fig. 2, in order to more clearly illustrate the technical solution and the advantages of the present invention, the following detailed description of the task flow scheduling method provided in the embodiment of the present invention may specifically include the following steps:

step 201: determining at least one target task configuration parameter and at least one target condition trigger configuration parameter in a task execution schedule, wherein the target condition configuration parameter comprises: year, month, day, hour, minute, second, week, etc.

Step 202: and configuring at least one target task configuration parameter and at least one target condition configuration parameter in the task execution schedule.

Step 203: and generating a target task execution schedule according to the configuration information, wherein the configuration information comprises condition trigger information, and the target task execution schedule comprises at least one target task.

Step 204: and drawing a task execution flow chart through a visual graphical interface according to the logic sequence of task execution of at least one target task in the target task schedule according to the target task execution schedule.

In particular, common tasks, such as: the method comprises a timing task, a delay task, a fixed frequency task, a Cron expression task and a condition triggering task. A user can draw a task execution flow by using a visual graphical interface, and can also write a task flow DSL script, and the tasks can be sequentially operated according to the flow after the system is loaded and released. The process can support a series connection mechanism, a parallel connection mechanism, a delay mechanism, a retry mechanism, a circulation mechanism and a fence mechanism, and can meet most process scenes.

If the writing of the task flow DSL script is adopted, functions of scheduling group management, flow filter, fault transfer and the like can be realized based on the meta-programming technology. The scheduling element programming can be used for enabling a scheduling plan to correspond to a scheduling flow group, namely the capacity of dynamically switching the flow during the running period, and meanwhile, filters can be added among the flow nodes and used for filtering the execution of some tasks and the operation of ending the flow in advance. The two functions can be used as a dispatching fault transfer function, and when an abnormal process occurs in the execution process, the abnormal process can be automatically switched to or terminated, so that system breakdown is avoided, and the capabilities of quick failure and safety failure are provided.

For example, in terms of task scheduling, in addition to simple scheduling of a single task, complex scheduling of multiple tasks may be achieved. Different tasks can be associated according to the internal dependency relationship in a DAG (demand oriented mapping) mode in a visual graphical interface in a dragging and drawing mode, so that visual arrangement of complex scheduling tasks is realized. Meanwhile, the execution states of the upstream and the downstream of a certain task can be visually observed through the DAG graph, the reason that the certain task is not executed is judged, the tasks which are influenced by deleting the certain task are deleted, and the like, so that the management is convenient.

Step 205: when at least two target tasks are executed in parallel, the task nodes are written into the tasks of the fragmentable type, so that the executors execute the tasks in a parallel mode after recognition.

Step 206: and determining whether the trigger condition corresponding to the condition trigger information is met.

Step 207: and executing the task execution flow corresponding to the task execution flow chart when the triggering condition corresponding to the condition triggering information is determined to be met.

Step 208: and receiving an execution result aiming at the task execution flow.

Step 209: according to the received execution result, setting at least one piece of identification information aiming at least one target task to enable the execution result to be visualized, wherein the identification information is used for representing feedback information of the execution result of the at least one target task, and the feedback information comprises: a completion status of the at least one target task, an exception status of the at least one target task.

Step 210: and according to the at least one piece of identification information, performing exception processing aiming at the target task execution flow corresponding to the exception state.

Specifically, the task can be visually arranged, and the task execution result can be statistically analyzed. Through the information which is durably stored in the database after each task is executed, visual charts such as a line graph, a bar graph and the like of historical execution task information are generated through statistical analysis, and the total number of tasks, the total number of task running times, the number of running success times, the number of running failure times and the like in the scheduling system can be clearly observed; and further analyzing to obtain a stability chart of the task according to the execution success and failure times of the task, and analyzing the complexity and the like of the task according to the execution overhead of the task, so as to provide data for implementation and development personnel, optimize task codes, scheduling processes and the like, and improve the system stability.

The visual arrangement can also comprise visual checking of information such as system load, memory, processes, CPUs and the like, so that a user can know the performance service condition of the current system conveniently, and server resources are distributed and used more reasonably.

Step 211: and when the newly added task execution flow is required, determining at least one newly added task execution flow, wherein the at least one newly added task execution flow comprises at least one newly added task, and the at least one newly added task is not included in the task execution flow chart.

Step 212: and determining at least one newly added configuration parameter corresponding to the at least one newly added task execution process.

Step 213: and performing parameter configuration on at least one newly added configuration parameter.

Step 214: and determining the logic relationship between at least one newly added task and at least one target task in the execution flow of at least one newly added task.

Step 215: and drawing the newly added task execution flow chart through a visual graphical interface according to the task execution flow chart and the logic relation between at least one newly added task and at least one target task.

In particular, tasks may be dynamically added, updated, and destroyed. The task adding support system embeds tasks, service calls and uploads task executable files.

Step 216: when at least two task execution flowcharts exist, aiming at a first task execution flowchart and a second task execution flowchart in the at least two task execution flowcharts, whether the first task execution flowchart and the second task execution flowchart have an association relation or not is determined.

Step 217: and if the first task execution flow chart and the second task execution flow chart are determined to have the association relationship, determining a target first task and a target second task which have the association relationship, wherein the target first task is contained in the first task execution flow chart, and the target second task is contained in the second task execution flow chart.

Step 218: it is determined whether the target first task needs to be executed first and the target second task needs to be executed after the target first task is executed, if yes, step 219 is executed, otherwise, step 221 is executed.

Step 219: the current execution state of the targeted second task is marked by the pause identification.

Step 220: and when the execution of the target first task is completed, canceling the pause identification mark of the target second task and triggering the target second task to start executing.

Step 221: it is determined whether the target second task needs to be executed first and the target first task needs to be executed after the target second task is executed, if yes, step 222 is executed.

Step 222: the current execution state of the targeted first task is marked by a pause identification.

Step 223: and when the execution of the target second task is completed, canceling the pause identification mark of the target first task and triggering the target first task.

The present invention may provide a variety of task registration schemes, such as: system built-in, service invocation, script invocation, and the like.

1. Tasks built in the system are that tasks are directly programmed in the scheduling system, the tasks are generally tasks directly related to the scheduling system, such as data persistence, backup and the like of the scheduling system, the tasks are directly registered on the scheduling system and are uniformly managed and executed by the scheduling system, and tasks can be scheduled for basic tasks according to requirements so as to realize more complex functions;

2. service invocation mainly refers to that a scheduling system directly invokes services provided by other systems. The calling mode is suitable for the fact that the task and the service system have strong dependency relationship, and the scheduling system only needs to call the specified service according to the trigger. The method can be specifically called by a URL (uniform resource locator) and a service registration center, and when the number of services is small, the URL is directly used for calling, so that the method is simple and easy to manage; as more and more services are provided, service URL configuration management becomes very difficult and can be invoked through a service registry;

3. script calls provide a method to start and manage processes. The method can execute Python scripts, jar packages, shell scripts and the like, the scripts or the programs are stripped from the service system, can be conveniently modified and repeatedly uploaded in a dispatching system, and is simple in development and free of invasion to the service system. Creating a scheduling system task using custom scripts is the most dominant task registration scheme.

The embodiments of the invention have at least the following beneficial effects:

1. in the embodiment of the invention, when the task is actually scheduled, because the execution cycle of part of the tasks is unclear, the tasks need to be repeatedly adjusted according to the actual operation condition of the project, and the project needs to be restarted after each adjustment, so that the tasks cannot be visually arranged according to the actual requirement to provide continuous services. Therefore, in order to implement the visual arrangement of the tasks, the task execution flow chart can be drawn according to the logic sequence of the target task execution through the visual graphical interface, and the configuration parameters corresponding to the tasks need to be determined for each target task, and the configuration parameters of the target tasks are configured correspondingly in the task plan execution table. The task execution schedule configured by the user is a target task execution schedule meeting the requirements of the user. Based on the configured target task execution schedule, the user can draw a task execution flow chart on a visual graphical interface according to the task execution logic of the user and the logic relation among the target tasks. Meanwhile, for the task nodes with the circular traversal, the tasks can be written into a task with a fragment type, the executors can execute the tasks in a parallel mode after recognition, and the traversed elements are collected and then executed in a fragment mode. The multi-task execution logic can be programmed through the visual graphical interface drawing process, and the complex task scheduling is realized while the operation is simple. Through the process, the task script is not required to be coded and run by developers, and the task can be visually arranged according to actual service requirements so as to realize task scheduling;

2. in an embodiment of the present invention, because the current task scheduling system cannot check the running state of the task online in real time, in order to check and monitor the running state of the task in real time, the running state of each target task can be determined according to the execution result of the task execution flow, and identification information for representing the running state of each target task is set for each target task according to the execution result of each target task, so that a user can check the corresponding identification information through a visual graphical interface to monitor the running condition of the task in real time, visualize the running state of the task in real time, and monitor the task on a basic basis, thereby finding the defects of the task in time to improve, and improving the working efficiency;

3. in an embodiment of the present invention, when a new addition is required based on an executed task execution flowchart according to actual project requirements, an original task execution flowchart may be used as a template, the configuration of new configuration parameters is performed on a new addition part first, the new addition execution flow may be run after the new configuration parameters are configured and a logical relationship is created by a user through a visual graphical interface, and meanwhile, when a plurality of similar task execution flowcharts are created, the same part may be extracted to make a flow template, and corresponding prototype attributes are designed for parameter configuration on a difference part, so that a plurality of task execution flowcharts may be arranged conveniently;

4. in an embodiment of the present invention, after performing visualization orchestration on a task, a function of multi-process collaboration can be supported among a plurality of task execution flowcharts having an association relationship. When the execution sequence between two task execution flowcharts on a certain node needs to be defined in time, a pause identifier may be added to the task execution flowcharts. When the progress and the execution result of the target task in the other task execution flowchart need to be waited, the current target task corresponding to the current task execution flowchart may mark the current execution state through the pause identifier, then wait for the result of the other process, and after the execution result of the other process is obtained, the current process may resume running.

5. In an embodiment of the present invention, since a parameter corresponding to each target task needs to be configured to generate a target execution schedule, and each target task is necessarily triggered and executed under a certain condition, in addition to configuring a basic task configuration parameter, a condition trigger configuration parameter corresponding to a trigger condition needs to be configured, for example, a specific trigger period may be input on a visual graphical interface for simple triggering, a delay time may be input for triggering, or a Cron expression may be input for triggering. In the process of triggering the Cron expression, a user can click a mouse to select information such as year, month, day, hour, minute, second, week and the like required by task triggering, so that the Cron expression can be automatically generated, and meanwhile, the execution of the flow corresponding to the target task can be triggered only when the triggering condition corresponding to the condition triggering information is met, so that whether the triggering condition corresponding to the condition triggering information is met needs to be determined, and when the triggering condition corresponding to the condition triggering information is determined to be met, the task execution flow corresponding to the task execution flow chart is automatically executed.

It should be noted that not all steps and modules in the above flows and system structure diagrams are necessary, and some steps or modules may be omitted according to actual needs. The execution order of the steps is not fixed and can be adjusted as required. The system structure described in the above embodiments may be a physical structure or a logical structure, that is, some modules may be implemented by the same physical entity, or some modules may be implemented by a plurality of physical entities, or some components in a plurality of independent devices may be implemented together.
