[0027] Embodiment 1

[0028] Figure 1 A flowchart of an application startup method is provided for the first embodiment of the present invention. This embodiment is applicable to the case where the cold startup speed of the target application is slow and a quick response to the transaction activity is required. The method can be executed by an application startup device, which can be implemented in the form of hardware and / or software, and can be configured in an electronic device. Figure 1 As shown, the method includes:

[0029] S110: Obtain an image program file of a target application, and execute an image startup command script of the image program file to restore an application process of the target application.

[0030] Among them, the target application may refer to an application with a complex framework and operating logic that needs to be quickly started when conducting transaction activities in an enterprise. The target application may refer to an application written in different code programming languages, and the specific one may be determined based on actual usage.

[0031] The image program file may specifically refer to an image file that can directly run a target application, and may also be used to directly execute a corresponding functional module in the target application, and may be generated and constructed in advance by a technician based on actual experience.

[0032] Specifically, during the production activities of an enterprise, when carrying out specific transaction activities, it is necessary to start the internal application of the enterprise. The internal program of the enterprise usually has a complex program framework and a large amount of cumbersome operation logic. Therefore, when cold starting the internal application of the enterprise, the efficiency is extremely low, which will greatly affect the efficiency of the enterprise's transaction activities. Therefore, the program process of the target application can be restored by obtaining the pre-built image program file of the target application and directly executing the image program file through the image startup command script.

[0033] S120, reading an application snapshot of a target application in a checkpoint folder in the image program file, and loading a program running file of the target application to start the program of the target application;

[0034] The image program file of the target application is generated based on the generated image startup command script and the intermediate image file; the intermediate image file is generated based on the executable program file of the target application. The intermediate image file can be a file for storing the program code and program startup script of the target application; the executable program file can be a file for storing the executable code of the target application, such as a JAR (Java Archive) file.

[0035] The checkpoint folder may be a folder for storing checkpoint data, specifically a folder for saving the current running state of the target application and supporting functions such as fault recovery and progress saving. The application snapshot may refer to a file that suspends the application process of the target application and saves the program running file of the target application in the current running state, specifically a record file including the program running state, configuration and parameters of the target application at a specific time point.

[0036] Specifically, after the program process of the target application is restored by the mirror startup command script, the application snapshot of the target application in the mirror program file can be read, and the program code file of the target application can be loaded accordingly, and the target application can be started by compiling through the mirror startup command. Exemplary, the target application can be a content management system used to manage and publish the digital content of the enterprise, such as adding or deleting website content, documents, etc. When new content is published on the website, the application snapshot of the content management system can be read directly through the mirror program file corresponding to the content management system, and the program code file of the content management system can be loaded, and the website content addition function in the content management system can be directly executed without going through the cold start links of the application such as execution environment startup, application framework startup, and business initialization, and then the corresponding functional module can be selected and run to complete the operation of the target application.

[0037] The technical solution of the embodiment of the present invention is to recover the application process of the target application by acquiring the image program file of the target application and executing the image startup command script of the image program file; read the application snapshot of the target application in the checkpoint folder in the image program file, load the program running file of the target application, so as to realize the program startup of the target application; wherein, the image program file of the target application is generated based on the generated image startup command script and the intermediate image file; the intermediate image file is generated based on the executable program file of the target application. In this technical solution, the image program file of the target application can be acquired and arranged in the target running environment, thereby improving the versatility of the target application; and when a transaction activity occurs, the target application can be directly started by using the image startup command script, thereby improving the cold start speed of the target application and the response speed of the enterprise to the transaction activity that occurs.

[0038] Embodiment 2

[0039] Figure 2 A flowchart of a method for starting an application program provided in Embodiment 2 of the present invention is provided. Figure 2 This is a flow chart of an application startup method provided in the second embodiment of the present invention. Based on the above embodiments, this embodiment further optimizes the above application startup method.

[0040] Furthermore, before the step of "obtaining the image program file of the target application, and executing the image startup command script of the image program file to restore the application process of the target application", add the step of "obtaining the executable program file of the target application; starting the executable program file, and after the executable program file is started, creating an intermediate image file; generating an image startup command script, and generating an image program file according to the image startup command script and the intermediate image file; the image startup command script is used to execute and restore the application process." to improve the method of accelerating the cold start speed of the target application. Figure 2 As shown, the method includes:

[0041] S210: Obtain the executable program file of the target application.

[0042] The executable program file of the target application may be obtained by the technicians in advance according to actual needs, and the application needs to be optimized for startup, and the executable code file of the application is obtained accordingly.

[0043] S220: Start the executable program file, and after the executable program file is started, create an intermediate image file.

[0044] Specifically, the intermediate image file can be created by pausing the program process of the target application after the executable program file of the target application is started, and saving the program code file of the suspended target application to the checkpoint folder as the intermediate image file.

[0045] Optionally, starting an executable program file, and after the executable program file is started, creating an intermediate image file, includes: starting an executable program file, and after the executable program file is started, creating an application snapshot of the target application, and storing the application snapshot of the target application in a checkpoint folder; generating a target container based on the checkpoint folder and the executable program file of the target application; and exporting the target container to obtain the intermediate image file.

[0046] Among them, the application snapshot can be a method for capturing the current state of the application, which can be used to recover data when a problem occurs in the application, and can also be used to analyze and adjust the performance of the application. Specifically, after the executable program file of the target application is started, the program process of the target application is paused, and the program state, configuration and data of the target application in the paused state are recorded, and the file generated according to the recording result is used as the application snapshot.

[0047] Among them, the checkpoint folder can be a folder for storing the intermediate state of the application. Specifically, after the program process of the target application is suspended, an application snapshot of the target application that has been started can be created in the checkpoint folder. Furthermore, an intermediate image file storing the program code of the target application can be generated based on the checkpoint folder and the executable program file of the target application. By starting the executable program file of the target application and creating an application snapshot of the target application after the program file is started to generate a target container and obtain an intermediate image file, the containerization of the target application is realized, which can improve the versatility of the target application in different application scenarios.

[0048] Optionally, start the executable program file, and after the executable program file is started, create an application snapshot of the target application, and store the application snapshot of the target application in a checkpoint folder, including: starting the executable program file, polling the health status check endpoint, and after the health status check endpoint determines that the target application has been started, start a preset sleep timer; if the current time point meets the end condition of the sleep timer, pause the target application, and store the program running files generated by the target application during the startup process in the form of an application snapshot in the checkpoint folder.

[0049] The health status detection endpoint can be an endpoint in the application for reporting the current running status. Specifically, it can be determined whether the current application has been started based on the feedback parameters received by the polling detection health status check endpoint. For example, when the status code 200 is fed back, it can be determined that the target application has been started and is in a healthy state; when the status code is not 200, it can be determined that the target application has failed to start.

[0050] Among them, the sleep timer may refer to the duration of keeping the target application in the current running state after the application is started, and specifically may be used to ensure that the target application is started and the running state is healthy. Among them, the program running file may include the program code of the target application and the configuration parameter information of the target application during the running process, and the configuration parameter information may include the command line parameters, configuration file parameters, environment variables and database parameter information of the target application. Specifically, it may be that after determining that the application is started, the sleep timer is started. Exemplarily, the sleep timer may be 5 seconds, and the specific sleep timer may be set by the technician based on experience. If the running state of the target application within 5 seconds is healthy, it can be determined that the target application is started and the program process of the target application is paused, and an application snapshot is generated according to the running data generated by the target application during the running process, and saved in the checkpoint folder. Polling detection can be performed through the health status check endpoint in the target application to determine whether the target application is started, which can improve the accuracy of the running state of the acquired target application to a certain extent and ensure that the target application is started.

[0051] Optionally, an executable program file is started, and after the executable program file is started, an application snapshot of the target application is created, and the application snapshot of the target application is stored in a checkpoint folder, including: adding a detection identifier parameter to the executable program file to obtain the added executable program file; starting the added executable program file, and polling the detection identifier parameter during the startup process; if the detection identifier parameter is started normally, pausing the target application, and storing the program running file generated by the target application during the startup process in the form of an application snapshot in the checkpoint folder.

[0052] Among them, the detection identifier parameter can be a parameter that can directly determine the running state of the target application during the running process of the target application. Exemplarily, the detection identifier parameter can be added to the executable file of the target application to identify the IP (Internet Protocol Address) address corresponding to the target application. For example, if the IP address corresponding to the target application is 128.168.1.1, the detection identifier parameter can be used to determine whether the target application has established a connection with the server through the IP address, and can request network data through the IP address, and whether the state of the network connection is normal. If the network connection state has a connection timeout and cannot establish a connection with the server, it can be determined that the detection identifier parameter fails to start, that is, the target application fails to start; if the network connection state is normal, it can be connected to the server and network data can be obtained, it can be determined that the detection identifier parameter is started normally, that is, the target application is started. Then, after the target application is started, the application process of the target application can be suspended, and the program running files generated by the target application during the startup process can be stored in the checkpoint folder in the form of application snapshots. Optionally, by adding a detection identifier parameter to the executable program file of the target application, after starting the executable program file, it is possible to directly determine whether the startup of the target application is normal based on whether the detection identifier parameter is started normally, thereby improving the operational efficiency of obtaining the running status of the target application and improving the reliability of the obtained status information.

[0053] Optionally, a target container is generated based on a checkpoint folder and an executable program file of a target application, including: creating an initial container, and copying the executable program file of the target application to the initial container to obtain an intermediate container; generating a startup script based on the folder address of the checkpoint folder; generating a target container based on the startup script and the intermediate container; wherein the startup script is used to load the application snapshot under the checkpoint file after the target container is started.

[0054] Among them, the container can be represented as a lightweight and portable virtualization technology, which can be used to package application programs and corresponding program running configuration parameters, such as command line parameters, environment variables, and database parameter information.

[0055] Specifically, an initial container may be created, the parameter files required to run the target application are packaged into an executable program file, and the file is copied and pasted into the checkpoint folder in the initial container to obtain an intermediate container storing the executable program file of the target application. Furthermore, a startup script for the executable program file may be generated, and the startup script is associated with the executable program file to generate a target container. By creating an initial container, the executable program file of the target application is copied into the initial container, and a startup script is generated based on the executable program file, and the startup script is associated with the executable program file to generate a target container for the target application, thereby realizing the containerization operation of the target application; the target application and the program running file may be sandboxed and directly stored in the hard disk, which greatly reduces the occupation of device memory resources by the target application in the absence of transactions.

[0056] S230, generating an image startup command script, and generating an image program file according to the image startup command script and the intermediate image file; the image startup command script is used to execute the recovery application process.

[0057] Specifically, generating the image program file may be to load and restore the application snapshot stored in the checkpoint folder through the image startup command script, and compile the program code file of the target application recorded in the intermediate image file to obtain the image program file. Specifically, it may be to construct a new image text file, obtain the application snapshot of the target application that has been started according to the intermediate image file, and then compile the program code file of the target application by specifying the default command executed when the container is started as the image startup command script, and generate the image program file of the target application.

[0058] S240: Obtain an image program file of the target application, and execute an image startup command script of the image program file to restore the application process of the target application.

[0059] S250, reading an application snapshot of a target application in a checkpoint folder in the image program file, and loading a program run file of the target application to start the program of the target application; wherein the image program file of the target application is generated based on a generated image startup command script and an intermediate image file; and the intermediate image file is generated based on an executable program file of the target application.

[0060] The technical solution of the embodiment of the present invention is to obtain the executable program file of the target application; start the executable program file, and after the executable program file is started, create an intermediate image file; generate an image startup command script, and generate an image program file according to the image startup command script and the intermediate image file; the image startup command script is used to execute the recovery application process. In this technical solution, the image program file of the target application can be generated according to the executable program file of the target application, and the image program file can be arranged in the target operating environment, which can improve the versatility of the target application; the generated image program file can be stored in the hard disk, does not need to occupy the memory resources of the terminal device and can be reused, and then when a transaction activity occurs, the target application can be directly started using the image startup command script, which improves the cold start speed of the target application and the response speed of the enterprise to the transaction activity that occurs.
