Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The code migration method is applicable in an application environment such as that of fig. 1, in which a computer device communicates with a server through a network. The computer devices may be, but are not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices. The server may be implemented as a stand-alone server.
In one embodiment, as shown in fig. 2, a code migration method is provided, and the method is applied to the server in fig. 1, and the method includes the following steps:
s201: acquiring source file and target conversion frame information; the target conversion frame information corresponds to a frame type; the source file includes a plurality of character strings to be matched.
Specifically, the method can be applied to a system code migration tool, and is used for converting a source file from a current technical framework to a migration tool of the same or different technical frameworks of a required framework version, the difference between the technical framework required to be migrated and the technical framework to be converted is not required to be analyzed offline by a developer, and code migration is performed manually according to the difference, so that the code migration efficiency can be effectively improved, and the labor cost can be reduced.
Among the frame types include, but are not limited to, database frames (e.g., SQLserver, mySQL, oracle), front-end technology frames (e.g., VUE, JS), and back-end technology frames (e.g., C, java, python). Wherein the target conversion frame information includes a target conversion frame and a conversion frame version. The target conversion framework is a new technical framework which is designated by a user and needs to be migrated. The conversion frame version is the frame version of the target conversion frame. The character string to be matched corresponds to a plurality of words in the source file.
Specifically, the user can select a target conversion frame and a corresponding conversion frame version to be converted according to actual needs in a display interface of the system code migration tool, and upload a source file to be converted at the same time, so that the server obtains the source file and conversion frame information.
S202: and determining the frame information to be converted corresponding to the source file according to the character string to be matched.
The frame information to be converted comprises frames to be converted and corresponding frame versions to be converted. The frame to be converted is the technical frame corresponding to the source file. The frame version to be converted is the frame version corresponding to the frame to be converted.
Specifically, the source file is scanned to match keywords with a predefined version specific character string, and if the keywords are matched, a technical framework and a framework version corresponding to the version specific character string are used as the framework information to be converted corresponding to the source file. The version specific character string is a specific keyword which is newly added or changed in different versions by different predefined technical frameworks. In this embodiment, by automatically detecting the frame information to be converted corresponding to the source file, the user does not need to manually select, and the requirement on the mastering degree of the source file is low and the universality is higher.
S203: acquiring a configuration file corresponding to the frame type; the configuration file is used for describing mapping relations between the plurality of source frame information and the target frame information.
The configuration file is a pre-created description file for storing active frame information and target frame information, and is used for describing the mapping relationship between source frame character strings corresponding to a plurality of source frames under a source frame version and target frame character strings corresponding to a target conversion frame under a conversion frame version. The source framework is the technical framework to be migrated. The target framework is a new technical framework requiring migration. The source frame information includes a source frame, a source frame version, and a source frame string. The source framework string is used for indicating keywords to be converted of the source framework under a certain source framework version. The target frame information includes a target frame, a target frame version, and a target frame string. The target frame string is used to indicate the target keywords that the target frame needs under the target frame version.
In this embodiment, the character strings in the source file are automatically converted by calling the configuration file, so that the main logic of the code is not affected, and the coupling between the service logic and the frame technology can be effectively reduced.
Illustratively, the configuration file may be a database framework type configuration file as shown in the following table:
s204: determining a target mapping relation from a plurality of mapping relations according to the frame information to be converted and the target conversion frame information; the target mapping relationship is used for indicating the mapping relationship between the source frame information matched with the frame information to be converted and the target frame information matched with the target conversion frame information; the source frame information includes a source frame string; the target frame information includes a target frame string.
Specifically, since a plurality of mapping relationships are stored in the configuration file, it is necessary to determine a target mapping relationship from the plurality of mapping relationships according to the frame information to be converted and the target conversion frame information selected by the user. For example, if the source frame corresponding to the source file is an ibatis frame, the source frame version is 1.10.3, the target conversion frame is mybatis, and the frame version is 4.11.5, the source frame in the source frame information stored in the configuration file is ibatis, and the frame version is 1.10.3; the target frame information is mybatis frame, and the mapping relation of the conversion frame version 4.11.5 is used as a target mapping relation.
S205: and matching the character strings to be matched in a matching mode corresponding to the character types to obtain character strings to be converted, which are matched with the character strings of the source frame.
Wherein the character types include, but are not limited to, keyword types and method types. Specifically, the matching modes corresponding to different character types are different, so that the character strings to be matched are matched in a targeted manner, and the applicability is higher. It can be understood that, since the character type includes a keyword type or a method type, when matching is performed by using the same keyword matching algorithm, only a code including the keyword "try" and the method is matched for the keyword of the method type, for example try.
S206: and converting the character string to be converted into a target frame character string according to the target mapping relation to obtain a target file of the source file under the target conversion frame.
Specifically, according to the description of the target mapping relationship, a plurality of groups of corresponding relationships between the source frame strings and the target frame strings, for example (< sql map >, < configuration >), (< sql map >, < mapper >) can be obtained, and according to the corresponding relationships, the to-be-converted strings matched with the source frame strings in the source file are converted into corresponding target frame strings, so as to obtain the target file of the source file under the target conversion frame.
In this embodiment, the source file and the target conversion frame information are obtained so as to determine the frame information to be converted corresponding to the source file according to the character strings to be matched in the source file, so that manual selection of a user is not required, the requirement on the mastering degree of the source file is low, and the universality is higher. And then, acquiring a configuration file corresponding to the frame type, wherein the configuration file stores mapping relations among a plurality of technical frames of different frame versions of different frame types so as to realize comprehensive system code maintenance of various frame technologies and frame versions. And then, determining a target mapping relation from a plurality of mapping relations according to the frame information to be converted and the target frame information, so as to match the character strings to be matched in a matching mode corresponding to the character types, obtain the character strings to be converted matched with the character strings of the source frame, and match the character strings to be converted in different matching modes aiming at different character types, thereby having high universality. And finally, converting the character string to be converted into a target frame character string according to the target mapping relation to obtain a target file of the source file under the target conversion frame, so as to realize automatic conversion of code migration, improve the system code migration efficiency, reduce human errors in the migration process, facilitate unified management and reduce the cost of a later maintenance system.
In an embodiment, as shown in fig. 3, in step 202, to-be-converted frame information corresponding to a source file is determined according to a to-be-matched character string, which specifically includes the following steps:
s301: keyword matching is carried out on the character strings to be matched according to the version specific character strings; the version specific character string is a specific keyword corresponding to a predefined technical framework under different versions.
Keyword matching includes, but is not limited to, using KMP algorithm, multimode string matching algorithm (Aho-coralick). Specifically, taking the multi-mode matching algorithm as an example, a plurality of character strings to be matched can be input into the multi-mode character string matching algorithm in full or batch mode for processing to determine whether the character strings to be matched with the version specific character strings exist in the source file.
It should be understood that the dictionary tree required in the multimodal string matching algorithm is constructed by a plurality of version specific strings predefined in this embodiment, and then string matching is performed according to the concepts of the success table and the failure table in the multimodal matching algorithm, so that it can be determined that keywords matched with the version specific strings exist in the source file.
S302: and if the source file has the character string to be matched with the version specific character string, taking the frame version and the technical frame corresponding to the version specific character string as frame information to be converted corresponding to the source file.
Specifically, if a keyword matched with the version specific character string exists in the source file, the frame version and the technical frame corresponding to the version specific character string are used as frame information to be converted corresponding to the source file, and if no character string matched with the version specific character string exists in the source file, prompt information can be generated to prompt a user to select the frame version of the source frame.
It can be understood that if the source file does not have a character string to be matched with the version specific character string, and possibly, the mapping relationship corresponding to the source frame does not exist in the configuration file, a prompt message may be generated to prompt the user to add the mapping relationship to the configuration file.
For example, if the keyword of the sqlMap tag in the v1 version of the ibatis framework is < sql-map >, and the keyword of the sqlMap tag in the v2 version is < sqlMap >, the < sql-map > may be used as a version specific character string of the ibatis framework in the v1 version, and if the keyword (i.e., < sql-map >) matched with the version specific character string exists in the source file, the framework version and the technical framework corresponding to the version specific character string may be used as the frame information to be converted corresponding to the source file, i.e., the source frame of the source file is the ibatis framework, and the source frame version is the v1 version.
In one embodiment, as shown in fig. 4, in step S204, a target mapping relationship is determined from a plurality of mapping relationships according to the frame information to be converted and the target conversion frame information, and the method specifically includes the following steps:
s401: and matching a plurality of mapping relations according to the frame information to be converted, and determining candidate mapping relations corresponding to the frame information to be converted.
Specifically, the mapping relationships in the configuration file are matched through the source frame and the frame version in the frame information to be converted, namely, the mapping relationship matched with the frame information to be converted is contained in the mapping relationships as a candidate mapping relationship. For example, if the configuration file includes mappings of SQLserver (source framework) -source framework version 2005-Oracle (target framework) -target framework version 10.2.0.1, SQLserver (source framework) -source framework version 2005-MySQL (target framework) -target framework version 5.6.23, and SQLserver (source framework) -framework version 2008-Oracle (target framework) -target framework version 10.2.0.1, if the source framework in the frame information to be converted is SQLserver (source framework) -source framework version 2005-Oracle (target framework) -target framework version 10.2.0.1, and SQLserver (source framework) -frame version 2005-MySQL (target framework) -target framework version 5.6.23, the two mappings are taken as candidate mappings.
S402: and matching the candidate mapping relation according to the target conversion frame information, and determining the target mapping relation.
Specifically, if the target transformation frame information is: the target frame is MySQL and the target frame version is 5.6.23, and then the candidate mapping relationship matched with the transformation frame information is taken as the target mapping relationship, that is, the SQLserver (source frame) -frame version is 2005-MySQL (target frame) -target frame version is 5.6.23 as described in the above example.
In one embodiment, as shown in fig. 5, in step S205, a matching method corresponding to a character type is adopted to match a character string to be matched, so as to obtain a character string to be converted matched with a character string of a source frame, and the method specifically includes the following steps:
s501: and if the character type is the keyword type, matching the character strings to be matched in a keyword matching mode to obtain character strings to be converted, which are matched with the character strings of the source frame.
The keyword types refer to tag fields of which the character strings to be matched are technical frameworks, such as < sql map >, < sql map >. Specifically, a keyword matching algorithm, such as KMP algorithm and multimode string matching algorithm (Aho-coralick), can be used for matching the keyword matching mode. The following description will be given of a keyword matching method using a multimodal string matching algorithm as an example.
S502: and if the character type is the method type, matching the character strings to be matched by adopting the regular expression to obtain the character strings to be converted, which are matched with the character strings of the source frame.
The method type refers to that the character string to be matched is a field representing the method, for example, try. Specifically, for a string to be matched for such character types, matching may be performed by constructing a regular expression, for example, for matching a string to be matched of try. In the embodiment, by adopting different matching modes for different character types to match, the universality of code migration can be effectively ensured, and the implementation of tools is realized.
In one embodiment, the source frame string includes a plurality of characters to be tested carrying sequence tags; as shown in fig. 6, in step S501, a keyword matching method is adopted to match a character string to be matched, so as to obtain a character string to be converted matched with a character string of a source frame, and the method specifically includes the following steps:
s601: constructing a dictionary tree corresponding to the source file according to the plurality of character strings to be matched; wherein the dictionary tree includes a plurality of node characters.
The node characters refer to characters stored in each child node in the dictionary tree. The dictionary tree, also called Trie tree, word search tree or prefix tree, is a multi-way tree structure for quick retrieval, e.g. the dictionary tree for english letters is a 26-way tree and the dictionary tree for numbers is a 10-way tree. Basic properties of Trie include:
(1) The root node does not contain characters, and each node contains only one character except the root node.
(2) From the root node to a certain node, the characters passing through the path are connected together to be the characters corresponding to the node.
(3) All children of each node contain different characters.
Specifically, the process of constructing the corresponding dictionary tree according to the character string to be matched is as follows: firstly initializing a root node (hereinafter referred to as root node) of a tree structure, then comparing whether each character in a word (i.e. character string to be matched) to be inserted is in a child node of a dictionary tree in sequence from the root node, if so, pointing a pointer to the child node, comparing the next character (i.e. second character of the character string to be matched), if not, creating a child node to store the current character, continuing judging the next character until all characters in the character string to be matched are judged to be finished and all characters are in the dictionary tree, and completing the construction of the dictionary tree.
S602: traversing the dictionary tree, and matching each character to be detected with the node character according to the sequence label to obtain a character string to be converted, wherein the character string to be converted is matched with the character string of the source frame.
Specifically, if the character to be detected with the source frame character string sequence label as the first position exists in the letter tree, the character is used as a current node, the successful pointer is pointed to the node character corresponding to the next node according to the path of the successful pointer in the letter tree, if the node character pointed by the pointer is matched with the character to be detected with the second sequence label in the frame character string, the character to be detected corresponding to the second sequence label is used as the current node, the steps of pointing the successful pointer to the node character corresponding to the next successful node according to the path of the successful pointer in the letter tree are continuously executed until the failed pointer is pointed to the root node, circulation is stopped, a target termination node is obtained, traversing is carried out according to the path of the successful pointer in the letter tree based on the root node and the termination node, and the character string to be converted is obtained.
For example, assuming that the source frame string is her, (the characters to be tested are "h", "e", r ") are illustrated by taking the letter tree of fig. 7 as an example (the dotted line part in the figure is the direction of the failure pointer; the solid line part is the path of the success pointer, the root is the root node, and the gray circle is the termination node), since the first character (i.e.," s ") exists in the letter tree, the character" h "is taken as the current node, and the success pointer is directed to the node character corresponding to the next node according to the path in the letter tree, i.e.," e ".
The server reads the character to be tested (i.e. "h") corresponding to the second sequence tag of the source frame character string, and matches the node character "h" pointed by the successful pointer at this time, as can be seen from fig. 7, the character to be tested "h" corresponding to the second sequence tag is matched with the node character "h", the character to be tested corresponding to the second sequence tag is taken as the current node, the step of pointing the successful pointer to the node character corresponding to the next node according to the path of the successful pointer in the letter tree is continuously executed, and the step of matching the node character "r" pointed by the pointer at this time with the character to be tested "r" corresponding to the third sequence tag in the read source frame character string is continuously executed, as can be seen from fig. 7, the character "r" to be matched with the node character "r", and the word obtained from the root node to the termination node is recorded as the character string to be converted, namely "her", the step of pointing the successful pointer to the node character corresponding to the next node in the letter tree is continuously executed, and the step of pointing the node character corresponding to the next node according to the successful pointer in the letter tree is continuously executed, and the step of pointing the node to the node character corresponding to the next node is ended, and the word is recorded as the word to be converted.
In the embodiment, the dictionary tree is constructed by the character strings to be matched, so that the data storage space can be effectively reduced; and then, performing character string matching by traversing the dictionary tree to obtain a character string to be converted, which is matched with the character string of the source frame, so that unnecessary character string comparison is reduced to the maximum extent, and the query efficiency is effectively ensured.
In one embodiment, as shown in fig. 8, after step 203, the code migration method further includes the following steps:
s701: and receiving a custom editing instruction input by the client, wherein the custom editing instruction comprises source frame information and corresponding target frame information.
The custom editing instruction is an instruction for triggering custom editing of the configuration file. The custom editing instruction includes, but is not limited to, adding, modifying or deleting configuration files.
Illustratively, the custom edit instruction is exemplified as a "new" operation. Specifically, the user can perform the custom editing interface through the custom editing module (such as a button form) in the interface, so as to edit according to the item to be edited displayed by the custom editing interface. The item to be edited comprises source frame information and corresponding target frame information, wherein the source frame information comprises a source frame, a source frame version and a source frame character string. The target frame information comprises a target frame, a target frame version and a target frame character string, and is used for carrying out custom editing or configuration on the information dimension so as to enable the server to acquire the source frame information and the corresponding target frame information.
S702: and responding to the custom editing instruction, and storing the source frame information and the corresponding target frame information in a configuration file in an associated manner so as to update the configuration file.
Specifically, the server responds to the custom editing instruction, and stores the source frame information and the target frame information in the configuration file in an associated mode so as to update the configuration file. It should be noted that, the corresponding relationship between the source frame information and the target frame information in the item to be edited is preset, and the user only needs to edit correspondingly without setting manually. In the embodiment, customization is realized by providing a custom editing interface for users and carrying out custom editing, and the method has the advantage of high expandability.
It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic, and should not limit the implementation process of the embodiment of the present invention.
