Description

[0002] With the continuous growth of business volume, multiple applications exist in a service cluster at the same time. Data exchange between various business applications needs to be carried out through open interfaces, databases, cache services and other methods to ensure the normal operation and display of data in various business applications.

[0042] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0044] like Figure 1 As shown, the present invention provides a method for setting a multi-application communication link applied to a service cluster, and the method for setting a multi-application communication link applied to a service cluster includes:

[0045] In step S11, when any application needs to perform data interaction in the server cluster, it queries the configuration file of the cache database to check whether the communication link involved in the data interaction exists;

[0046] In step S12, if it exists, determining whether the access according to the communication link is successful;

[0047] In step S13, if the access fails, it is determined whether the captured exception is related to the communication link;

[0048] In step S14, if relevant, determining whether the corresponding communication link in the communication link configuration file in the preset file server is consistent with the communication link involved in the data interaction;

[0049] In step S15, if there is inconsistency, the communication link involved in the data interaction is changed to a corresponding communication link in the communication link configuration file.

[0050] In one embodiment, in a server cluster, when multiple applications interact with each other, the configuration, update and maintenance of the communication link is a task with a huge workload and high real-time requirements. The technology in this embodiment enables each application to use the correct communication link during the data interaction process, avoiding data interaction failure or abnormality caused by changes in the communication link.

[0051] When any application needs to interact with data in a server cluster, it needs to communicate with other applications or services. Query the configuration file of the cache database to check whether the communication link involved in the data interaction exists. Query the configuration file in the cache database to check whether the required communication link already exists, so as to improve the query speed, reduce the dependence on the remote configuration file, reduce network delay, and improve the efficiency of data interaction. If it exists, determine whether the access is successful according to the communication link. Use the communication link in the cache database to try to interact with data, determine whether the access is successful, and ensure that the communication link is available. If the access fails, determine whether the captured exception is related to the communication link. Capture the exception information when the access fails, and determine whether the exception is caused by a communication link problem, such as network failure, address error, etc. If relevant, determine whether the corresponding communication link in the communication link configuration file in the preset file server is consistent with the communication link involved in the data interaction. Obtain the latest communication link configuration file from the preset file server. Compare whether the communication link in the cache database is consistent with the communication link in the configuration file. If not, change the communication link involved in the data interaction to the corresponding communication link in the communication link configuration file. Update the communication link used in the application to the latest configuration, retry data interaction, and finally ensure successful communication.

[0052] Determine whether it is necessary to set up a communication link for any application, the setting includes any of deployment and update. For new deployment or version update of the application, determine whether it is currently necessary to set up or update the communication link. When the above judgment is true, update all communication links involved in the application in the communication link configuration file in the preset file server. In the configuration file of the file server, add or update the communication link information related to the application to ensure that the communication link configuration of all applications is kept up to date. Before the application is deployed, set up the preset file server and establish a communication link configuration file. Deploy the file server as a center for centralized management of communication link configurations. Create an initial communication link configuration file for the application to use.

[0053] When any application needs to perform data interaction in the server cluster, it queries the configuration file of the cache database to check whether the communication link involved in the data interaction exists. If not, the corresponding communication link in the communication link configuration file in the preset file server is obtained and written into the data cache library, and data interaction is performed. The required communication link is obtained from the file server, the obtained communication link is written into the cache database, the local cache is updated, and the new communication link is used for data interaction.

[0054] If the corresponding communication link in the communication link configuration file in the preset file server is inconsistent with the communication link involved in the data interaction, the communication link involved in the data interaction will be updated in the cache database. Update the communication link in the cache database to make it consistent with the configuration in the file server. Re-interact with the data according to the updated communication link in the cache database. Retry the data interaction using the updated communication link. The file format of the communication link configuration file includes any one of JSON, XML, XLSX, CSV, and TXT. The configuration file can adopt a variety of formats to meet the needs of different applications and environments, so as to improve the flexibility and compatibility of the system and facilitate parsing and maintenance.

[0055] The application needs to communicate with other services, triggering the process. Check whether the required communication link exists in the cache. If it exists, try to use the communication link for data interaction. If successful, the process ends and the data interaction is normal. If it fails, determine whether the exception is related to the communication link. If it is related, obtain the latest communication link configuration from the file server, compare and update the communication link, update the cache database, and retry data interaction. If it is not related, follow other exception handling processes. If the communication link does not exist, obtain the communication link configuration from the file server, write it to the cache database, and then interact with data. When deploying or updating the application, determine whether the communication link needs to be set. If necessary, update the communication link in the configuration file of the file server. The configuration file supports multiple file formats to improve compatibility.

[0056] The cache database can provide fast access to communication link information, reduce dependence on remote file servers, improve system performance, and reduce network latency. Communication link-related exceptions indicate network unreachability, address errors, timeouts, etc. The communication link needs to be updated to ensure successful data interaction. Non-communication link-related exceptions indicate data format errors, insufficient permissions, etc., and follow the regular exception handling process without involving communication link updates.

[0057] The preset file server configuration file uniformly stores and manages the communication link configuration of all applications. When the communication link changes, you only need to update the file server configuration file to simplify maintenance. When deploying or updating an application, determine whether the communication link needs to be set or updated, and update the communication link configuration file of the file server. During runtime detection, when the application fails to interact with data and the exception is related to the communication link, the application obtains the latest configuration from the file server. Common formats and their characteristics: JSON is lightweight, easy to parse, and suitable for Web applications. XML is structured, extensible, and suitable for complex data. XLSX is in tabular form and easy to view and edit manually. CSV is simple, plain text, and suitable for simple data exchange. TXT is flexible and customizable. Select the appropriate format based on application requirements and environment.

[0058] Automatically update the communication link. When the communication link changes, the system can automatically detect and update it to reduce human errors. Reduce data interaction failures, update the communication link in time, and ensure smooth communication between applications. Improve the flexibility and scalability of the system, support multiple configuration file formats, meet the needs of different applications, and enhance system compatibility. Combined with the cache database and file server, it has both the efficiency of caching and the convenience of centralized management. Reduce operation and maintenance and development costs, automate configuration management, reduce the workload of manual configuration and maintenance, and unify configuration management, simplify the configuration update process, improve work efficiency, make problem location and resolution more convenient, and make each module have clear responsibilities for easy expansion and optimization.

[0059] It is suitable for situations where there are many nodes in the server cluster and the configuration management is complex. It can realize centralized management configuration and improve system consistency. In addition, many applications and services change dynamically and communication links are frequently updated. It can automatically detect and update communication links to adapt to dynamic environments. In the face of the problem that multiple updates may lead to version confusion, a version control system (such as Git) is introduced to manage configuration files, and version numbers are added to configuration files to ensure version consistency.

[0060] During the configuration of the server cluster, the establishment of the file server takes precedence over the deployment of business applications. Files uploaded in each application are stored in the file server, and when each application accesses a file, the access address is based on the relative path to access the file server, without having to worry about changes in the server's IP address or application domain name.

[0061] Assume that there are three applications A, B, and C deployed in the server cluster. Application A communicates with application B and application C to exchange data. The data exchange method is in the form of providing an interface to the outside world:

[0062] Under normal circumstances, application A requests the interface of application B to obtain data in application B. Through network requests (Http and other methods), it accesses the data interface provided by application B to obtain data and calculate, store, and display it in the application A system. When application B migrates, changes its IP address, or changes its domain name, application A needs to update the network request address in this application and then use the above process to ensure normal data acquisition. Similarly, for application C, the same process is also required to ensure data communication between application C and application A.

[0063] The process of updating the communication link is only when the service environment of application A changes. If the above situation occurs simultaneously in applications A, B, and C, it is necessary to update a series of communication links such as application A to application B, application A to application C, and application B to application A. The above process requires the cooperation of operation and maintenance personnel and developers to ensure the accuracy and reliability of the data acquisition link.

[0064] By utilizing the file sharing feature of the file server in the server cluster, a unified configuration file is used to provide data service links to each application for data update. All applications interact with the configuration files in the file server. The specific process of the method implementation is as follows:

[0065] 1. Develop a standard format file as the configuration file for each application to update configuration information, which is also the file that the operation and maintenance personnel need to update during the migration work. The file can be in JSON, XML, XLSX, CSV, TXT and other file formats, but the primary consideration is to facilitate developers to read and operation and maintenance personnel to update the content. Taking the JSON format file as an example, create a config.json file in the shared file server. Whenever the above-mentioned application migration and other tasks occur, update the information in the config.json file. The code is as follows:

[0066]

[0067]

[0068]

[0069] 2. Cache update process (each application updates the access address through the configuration file). This process usually occurs first after the application is deployed, and also occurs during the business process. Figure 2 shown.

[0070] 1) The application queries the cache database to see whether the configuration information of the application to be accessed exists in the cache.

[0071] 2) If it exists, enter the business process and request the required data.

[0072] 3) If it does not exist, go to the directory where the configuration file is located in the file server and search for the config.json file. If the file exists, go to the next step. Otherwise, send a text message to notify the operation and maintenance personnel to perform maintenance.

[0073] 4) Access the configuration file to check whether the required application information exists. If so, write the corresponding information to the cache database (the cache duration is customized by the business scenario). Otherwise, notify the operation and maintenance personnel to update the data.

[0074] 5) After completing the corresponding information caching work, enter the business process.

[0075] 3. Business processes occur during the daily operation of the application. When completing migration and other scenarios, they will occur after the update process, as shown in the attached Figure 3 shown.

[0076] 1) Applications request data based on business needs.

[0077] 2) Determine whether the request is within the normal range in the request. If it can be returned normally, continue with the subsequent business process.

[0078] 3) If the data cannot be returned normally, the exception handling process is entered to capture the access exception and determine whether it is related to the access address exception (such as capturing network exception or link exception, etc.).

[0079] 4) If the captured exception is not related to the access address or cannot be determined, notify the project leader of the business module for manual verification.

[0080] 5) If the captured exception is related to the access address, query the configuration file and access the required application configuration information in the configuration file, compare the obtained information with the information in the current application cache one by one, and if the current cache content is the same as the configuration file content, notify the operation and maintenance personnel to confirm whether the configuration information needs to be updated.

[0081] 6) If the cache content is different from the configuration file content, the cache update process is entered, and in the cache process, the business process is re-triggered to ensure that the program can be closed-loop, ensuring data real-time and program reliability.

[0082] The technical solution in this embodiment realizes the automatic detection, update and maintenance of multi-application communication links through the combination of cache database and preset file server. It reduces manual intervention and improves work efficiency; uses cache database to increase access speed and reduce network latency. By automatically updating the communication link, the success rate of data interaction is ensured; supports multiple configuration file formats to adapt to different application requirements. In modern distributed systems and microservice architectures, the management of communication links is a key issue; the access links of each application can be updated to achieve fast and accurate deployment of multiple applications and ensure the technical effect of stable communication between applications.

[0087] The third determination module 44, if relevant, determines whether the corresponding communication link in the communication link configuration file in the preset file server is consistent with the communication link involved in the data interaction;

[0088] If there is inconsistency, the changing module 45 changes the communication link involved in the data interaction to a corresponding communication link in the communication link configuration file.
