Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of computer, in particular to a downstream service search method based on annotation form, a computer readable storage medium, an electronic device and a computer program product. BACKGROUND

[0002] Spring framework can simplify Java enterprise development, has many advantages such as providing powerful and stable functions, and has been widely used in the Internet industry. The core mechanism of Spring is dependency injection (supporting multiple ways such as XML, annotation, etc.), which can reduce the coupling relationship between computer programs to a certain extent. Using this framework, if the inventory service needs to optimize the function logic, the optimized service code can be implemented by adding the version number on the basis of not changing the original service name. The calling party generally only needs to modify the downstream service annotation version number to achieve cooperation and transformation, greatly reducing the workload and reducing the production risk.

[0003] If the downstream service involves transformation, all calling parties generally need to cooperate in testing, at which time the services of all calling parties need to be sorted out. The calling relationship registered by the system is often not complete, and some may be missing. If the transformation is missed, there is a great production risk in the later period. Therefore, a special software (such as FilelLocatorPro) is generally used to scan the code library.

[0004] However, there are the following problems in scanning the code library by using special software: 1. Special software can directly scan based on string + path conditions, but many Java files that do not involve calling the service will also be scanned out, and further screening is required, which is time-consuming and laborious. 2. Special software only supports scanning a single service name each time, and if many downstream services involve optimizing internal function logic at the same time, multiple scans are required. Each time needs to wait for the previous scan to be completed, and then manually execute the scan of the next service, which cannot batch scan multiple services at a time, resulting in a repetitive and tedious process. SUMMARY

[0005] The present application aims to at least solve one of the technical problems in the related art. To this end, the purpose of the present application is to provide a downstream service search method based on annotation form, a computer readable storage medium, an electronic device and a computer program product, to improve search efficiency and reduce the use threshold.

[0006] To achieve the above object, the embodiment of the present application provides a downstream service search method based on an annotation form, which comprises the following steps: defining a first data container and a second data container, wherein the first data container is used for storing service calling information, and the second data container is used for storing downstream service information; newly creating a target Excel file, wherein the target Excel file is used for storing the downstream service information to be searched, and the row name of the target Excel file is defined as an annotation name, a version number and a downstream service name; reading the downstream service information in the target Excel file and storing the downstream service information into the second data container; determining a scanning path according to the data in the second data container, traversing all files under the scanning path, and screening out upstream service files; storing the stored service information corresponding to the upstream service files into the first data container; and outputting the data collected by the first data container to a designated Excel file.

[0020] Embodiments of the present application are described in detail below with reference to the attached drawings. The embodiments described below are examples and are intended to explain the present application, and are not to be understood as limiting the present application.

[0021] Some embodiments of the present application are described below in detail with reference to the accompanying drawings. Embodiments described below and features in the embodiments can be combined with each other in the case of no conflict.

[0022] Reference is made below to the accompanying drawings Figure 1 - the accompanying drawings Figure 3 A downstream service search method based on an annotation form, a computer readable storage medium, an electronic device, and a computer program product according to an embodiment of the present application are described below.

[0023] Figure 1 is a flowchart of a downstream service search method based on an annotation form according to an embodiment of the present application.

[0024] As shown in Figure 1 , the downstream service search method based on an annotation form includes:

[0025] S1, defining a first data container and a second data container, wherein the first data container is used to store service call information, and the second data container is used to store downstream service information.

[0026] As an example, a Java class SingleServiceRelatedToTheCall can be defined as the first data container, which defines annotation name, version number, downstream service name, upstream service name, path, and the like. A Java class DownstreamServiceInformation can be defined as the second data container, which defines annotation name, version number, downstream service name, and the like.

[0027] S2, create a target Excel file, wherein the target Excel file is used to store the downstream service information to be searched, and the row name of the target Excel file is defined as the annotation name, the version number and the downstream service name.

[0028] As an example, an Excel file DownstreamServiceInformation.xls can be created. As shown in the following table, the column name of DownstreamServiceInformation.xls is defined as the annotation name, the version number and the downstream service name, and the information related to the downstream service (one or more) to be searched is input into the file.

[0029] Annotation name Version number Downstream service name Reference 1.0 DownstreamService1 Reference 1.1 DownstreamService2

[0030] It should be noted that the Excel is created to facilitate the user to uniformly fill in the information related to the downstream service (three columns in the Excel) to be scanned, and the information in the file is read for further processing.

[0031] S3, read the downstream service information in the target Excel file and store it in the second data container.

[0032] It should be noted that the "target downstream service information" in the Excel is loaded into the memory to provide directly accessible data for subsequent scanning and matching.

[0033] S4, determine a scanning path according to the data in the second data container, traverse all files under the scanning path, and screen out upstream service files.

[0034] As an example, all files under the scanning path can be recursively traversed to screen out files that can contain service call annotations.

[0035] S5, store the storage service information corresponding to the upstream service file to the first data container.

[0036] S6, output the data collected by the first data container to a specified Excel file.

[0037] It should be noted that the collected call relationship data can be presented in a structured form to facilitate user viewing and analysis.

[0038] The downstream service search method based on the annotation form of the embodiment of the application only needs to input one or more service annotation names, version numbers and downstream service names in a target Excel file, and then specify a search path, so that all upstream service information related to the calling of the service can be obtained by one-time operation. The search efficiency is improved, and the use threshold is reduced. At the same time, the one-time batch search of multiple downstream services is supported, the operation times are reduced, and the running time is shortened.

[0039] In some embodiments, the step of reading the downstream service information in the target Excel file and storing in the second data container comprises:

[0040] S31, reading each row of data in the target Excel file by a byte stream circulation mode, and temporarily storing each row of data in a temporary object.

[0041] It should be noted that the target Excel file is opened by using a byte stream (such as FileInputStream in Java), and the file content is read in a streaming manner, rather than loading the entire file into the memory at one time.

[0042] S32, putting the downstream service information in the temporary object into the second data container.

[0043] In this embodiment, by using the byte stream circulation reading and the temporary object intermediate storage, large files can be efficiently processed to avoid memory overflow, and the data integrity and accuracy can be ensured by step-by-step processing, so that the stability and reliability of the downstream service information loading are improved.

[0044] In some embodiments, the downstream service information includes an annotation name, a version number and a downstream service name.

[0045] According to the data in the second data container, a scanning path is determined, all files under the scanning path are traversed, and upstream service files are screened out.

[0046] S41, traversing all files under the scanning path, and screening out all Java files.

[0047] As an example, the scanning range can be quickly narrowed by path positioning and suffix screening, and the Java files that may contain service call annotations are focused, so that the processing overhead of invalid files is reduced, and the efficiency of the subsequent steps is improved.

[0048] S42, reading the content of each Java file, and if the Java file includes the annotation name and / or the version number, the Java file is the upstream service file.

[0049] As an example, first, for each Java file screened out, the file content is read by character stream line by line, and then the file content is compared with the "annotation name" and "version number" in the second data container: check whether the annotation name of the target downstream service (such as order-service in @Downstream("order-service")) is contained; check whether the corresponding version number (such as version="v2.0.0") is contained; as long as any one of the conditions "contains annotation name" or "contains version number" is met, it is determined that the file may call the target downstream service; for the Java file meeting the condition, record its path or reference, and mark it as an "upstream service file".

[0050] In this embodiment, the range is preliminarily narrowed down by file type screening, and accurate positioning is realized by content matching, which together completes efficient screening of upstream service files from massive files, and lays a foundation for subsequent collection of service call information.

[0051] In some embodiments, the step of reading the content in each of the Java files, and if the Java file includes the annotation name and / or the version number, regarding the Java file as the upstream service file, includes:

[0052] S421, defining a third data container, wherein the third data container is used for temporarily storing each line of data in the Java file in the current scanning path.

[0053] S422, reading each line of data in the Java file under the scanning path in a loop, and adding each line of data to the third data container.

[0054] S423, if the current line is greater than 1 and contains the downstream service name, removing the space in the previous line of data of the current line, and determining whether the previous line of data contains the annotation name and / or the version number.

[0055] S424, if yes, determining that the Java file is an upstream service file that calls the downstream service.

[0056] As an example, if no, it is determined that the Java file is not an upstream service file that calls the downstream service.

[0057] In this embodiment, by reading line by line and temporarily storing data, combined with accurate matching of the association between the annotation and the service name in the context line relationship, not only can the redundant overhead of full-text scanning be avoided, but also the accuracy of annotation recognition can be improved, irrelevant files can be effectively filtered, and the efficiency of upstream service file screening can be improved.

[0058] In some embodiments, when traversing the files under the scanning path, if a subfolder is encountered, a recursive call is made to the traversal operation to obtain the Java files in the subfolder.

[0059] In this embodiment, by making a recursive call to traverse the subfolder, it is ensured that all levels of Java files under the scanning path are retrieved without omission, without the need for manually processing the nested directories layer by layer, ensuring the completeness of the file scanning, simplifying the traversal logic, and improving the processing efficiency.

[0060] Next, the specific implementation process of the annotation-form-based downstream service search method of the present application will be described with reference to the following example: Figure 2

[0061] Step 1, define a Java class DownstreamServiceInformation, which defines attributes such as annotation name, version number, and downstream service name; define a Java class SingleServiceRelatedToTheCall, which defines attributes such as annotation name, version number, downstream service name, upstream service name, and path.

[0062] Step 2, define a property List <singleservicerelatedtothecall>serviceRelatedToTheCalls is used to store the information of upstream services which meet the requirements (annotation name + version number + downstream service name).

[0063] Step 3, create a new Excel file: DownstreamServiceInformation.xls, column name definition is annotation name, version number, downstream service name, and input the information of the downstream service (one or more) to be searched into the file.

[0064] Step 4, define a method List <downstreamserviceinformation>readExcelData(String fileName), where the parameter fileName is the file location path of Downstream ServiceInformation.xIs file, each line of data in the DownstreamServiceInformation.xIs file is read in a byte stream mode, the read data is assigned to the temporary variable DownstreamServiceInformation downstreamServiceInformationtmp corresponding attribute (the temporary variable plays a role of caching data), and then downstreamServicelnformationtmp is added to List <downstreamserviceinformation>downstreamServiceInformations.

[0065] Step 5, define a method findDownstreamServiceInformation(String path, DownstreamServiceInformation downstreamServiceInformation), the main logic of the method is:

[0066] (1) define a property List <string>findServiceInfolist is used to temporarily store each line of data in the Java file scanned in the current path.

[0067] (2) Read each line of data in the Java file under the path in a loop, and add each line of data to findServiceInfolist. If the line number LineNum > 1 and contains the name of the downstream service (the name of the downstream service is an attribute of the parameter downstreamServiceInformation in this method), further judgment is made:

[0068] Explanation: Because the service name generally appears in the next line according to the fixed usage form of the annotation, if the line contains the name of the downstream service involved, and the line number is greater than 1, it is judged that the previous line may contain the annotation version number and other information, and to avoid program errors.

[0069] First, eliminate the spaces in the previous line of data findServiceInfolist.get(LineNum-1), and then judge whether it contains the @ annotation name (version="version number") (the annotation name and version number are also attributes of the parameter downstreamServiceInformation in this method). If so, it means that the search has been found, and the annotation name, version number, downstream service name, upstream service name (i.e. the Java file name in the current path), path (path), etc. are assigned to temporary variables SingleServiceRelatedToTheCall singleServiceRelatedToTheCall corresponding attributes, and then the assigned singleServiceRelatedToTheCall is added to serviceRelatedToTheCalls, and the while loop is exited.

[0070] Step 6: Define a method getFiles(List <string>The method mainly traverses all files under the path paths (a path set with search files): if it is still a folder (judged by calling the findDownstreamServiceInformation method internal logic), the getFiles method is recursively called to obtain the files in the folder; if it is a file, the findDownstreamServiceInformation (String path, DownstreamServiceInformation downstreamServiceInformation) method is called to continue the remaining logic.

[0071] Description: The files in the folder can be Java files or subfolders. Generally, the files to be scanned are Java files, and for subfolders, it is necessary to recursively determine whether the subfolder contains Java files. The method searches all Java files in paths.

[0072] Step 7: Assign downstreamServiceInformations.size() to m, and i = 0.

[0073] Step 8: Determine if i ≤ m-1:

[0074] (1) If yes, call getFiles (parameter 1, parameter 2) and go to step 9.

[0075] (2) If no, go to step 13.

[0076] Step 9: Assign parameter 1.size() to n, and j = 0.

[0077] Step 10: Determine if j ≤ n-1:

[0078] (1) If yes, go to step 11.

[0079] (2) If no, i = i + 1, and go to step 8.

[0080] Step 11: Call findDownstreamServiceInformation (parameter 1.get(j), parameter 4) to determine if parameter 1.get(j) is a folder:

[0081] (1) If yes, go to step 8 (1) and recursively call the getFiles method.

[0082] (2) If no, read the data of each line of the parameter 1.get(j) file.

[0083] Step 12, judge whether the current line contains the downstreamServiceInformation attribute downstream service name and the previous line contains the corresponding annotation.

[0084] (1) If yes, add the related information to serviceRelatedToThecalls, jump out of the while loop, j=j+1, and enter step 10.

[0085] (2) If no, judge whether there is next line of data.

[0086] ① If yes, move the current line to the next line and enter step 12.

[0087] ② If no, j=j+1, and enter step 10.

[0088] Step 13, output the data of serviceRelatedToTheCalls to the Excel file (involving query results of calling downstream services.xIs) of the specified format.
