Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "comprising" and "having," and any variations thereof, as referred to in embodiments of the present invention, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may alternatively include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
As shown in fig. 1, the present invention provides a method for evaluating the adaptation of application codes of a heterogeneous database, including:
selecting configuration information for an application code of an application program to be evaluated;
running the application program according to the configuration information, analyzing the adaptability of the application code by using a preset rule, and generating an analysis result of the application code to be modified;
generating a migration assessment report based on the analysis results.
The method aims at the application system adaptation problem in the heterogeneous database migration scene, and the tool for analyzing and evaluating the migration workload of the application system is realized, the tool analyzes the project codes and generates the migration evaluation report, so that the integral one-click code analysis can be realized, the workload of developers is saved, and the working efficiency is improved.
The embodiment of the invention solves the problem of evaluation when the codes of the upper application system are adapted. For example, one management system is developed using java, the original database is oracle, and the database needs to be migrated to K-DB. Because the oracle and the K-DB are different in partial built-in functions, after the data is migrated, the management system cannot be directly used, and incompatible codes need to be adapted and modified. If the program in java is simply replaced, business logic problems are involved, and the embodiment of the invention analyzes the places needing to be modified of application codes according to built-in rules and forms reports for the development engineers to refer to.
The preset rules include: SQL syntax mapping rules or parsing rules for developing language and code frameworks.
The step of running the application program according to the configuration information, analyzing the adaptability of the application code by using a preset rule and generating an analysis result of the application code to be modified comprises the following steps:
running the application program according to the configuration information;
and analyzing the adaptability of the application code by using a preset rule in a directory traversal, regular matching or keyword search mode to generate an analysis result of the application code to be modified.
For example, 2 database function difference points, SQL syntax or function difference points, such as oracle and K-DB, are known, the corresponding mapping rules may be put into a rule engine, code scanning is performed in common scanning manners, such as directory traversal, regular matching or keyword search, etc., the area of the SQL statement is analyzed, and then the analysis result of the application code to be modified can be obtained by matching keywords.
For example, Oracle to K-DB has a replacement rule WMSYS.WM _ CONCAT function to be replaced by AGGR _ CONCAT, and the specific process is as follows: firstly, a regular expression non-greedy mode is used for matching SQL statement areas (possibly a plurality of areas) in a file, then WMSYS.WM _ CONCAT is directly replaced by text in the matched SQL statement to be AGGR _ CONCAT, and the result is output to a result module.
The configuration information comprises one or more of an original database type, a target database type, a code frame and an application code position.
The contents of the migration evaluation report include: the total number of sentences that need to be modified, and a sorted statistical list of sentences that need to be modified. The statement that the text wmsys. wm _ CONCAT is replaced by AGGR _ CONCAT and the like that needs to be modified is recorded in the classification statistical list.
The migration evaluation report is in a hypertext Markup Language (HTML) format, the HTML format is readable by a plurality of web browsers to generate files for transmitting various information by web pages, the Internet is a set composed of a series of transmission protocols and various files, HTML files are only one of the files, the HTML files are stored on server hard disks distributed all over the world, and users can remotely obtain the information and information transmitted by the files through the transmission protocols.
As shown in fig. 2, the present invention further provides a device for evaluating the adaptation of application codes of heterogeneous databases, including:
the configuration module 3 is used for selecting configuration information aiming at application codes of application programs to be evaluated;
the code analysis module 2 is used for running the application program according to the configuration information, analyzing the adaptability of the application code by using a preset rule and generating an analysis result of the application code to be modified;
and the report generation module 4 is used for generating a migration evaluation report based on the analysis result.
The above-mentioned heterogeneous database application code adaptation evaluation device further includes:
and the rule engine module 1 is used for storing the preset rules.
It should be noted that: the rule engine module 1 is internally provided with SQL grammar mapping rules (such as the corresponding relation of Oracle and K-DB SQL keywords and the like) for storing the heterogeneous database, analysis rules (such as the relative positions of Springboot mapper files and the like) of common development languages and code frames, and the rules internally arranged in the module can be added according to configuration requirements;
the configuration module 3: the user needs to select the relevant information of the configuration when starting the device, comprising: the type of an original database, the type of a target database, a code frame, the position of an application code and the like;
the code analysis module 2: the device executes an application program according to the configuration information, and the module analyzes the application code by adopting the modes of directory traversal, regular matching, keyword search and the like according to the corresponding rule of the rule engine;
the report generation module 4: the data result of the code analysis module generates an HTML report by the module, and the generated report content comprises: the user can directly open and view the analysis result to modify the total number of places, perform classification statistics on the modified places, and the like.
In addition, the operation process of the heterogeneous database application code adaptation evaluation device is explained as follows:
the method comprises the following steps: and the program starts to load the configuration file.
Step two: the code analysis module loads corresponding heterogeneous database conversion rules from the rule engine module to the memory according to the configuration information; in addition, if the application code framework is configured, the corresponding framework code analysis rule is loaded into the memory.
Step three: the program initiates scanning of the configuration source code directory and loads the associated file path into the memory task queue data structure. The selection configures the directory of the application code to be analyzed, and the type of the original database and the target database, and other information (such as the type of the code frame) can be optionally filled. If the corresponding frame code analysis rule exists, only the critical path and the file are scanned, otherwise, all the code files and the configuration files in the code directory are read and analyzed.
Step four: reading the configuration information input in the step one, selecting a corresponding conversion/mapping rule engine from the rule engines to analyze and scan the code catalogue, and adopting different analysis strategies according to different rules, for example, adopting a character string matching search mode for keyword matching and simultaneously combining the code frame type and the context environment for accurate determination.
In the specific execution process, multithreading parallel execution can be adopted, the code to be analyzed and the configuration file are firstly obtained from the task queue and read, and according to the conversion rule obtained in the step one, for example: oracle has a replacement rule WMSYS from K-DB WM _ CONCAT function to be replaced by AGGR _ CONCAT, and the specific process is as follows: firstly, a regular expression non-greedy mode is used for matching SQL statement areas (possibly a plurality of areas) in a file, then WMSYS.WM _ CONCAT is directly replaced by text in the matched SQL statement to be AGGR _ CONCAT, and the result is output to a result module.
In addition, if the analysis and positioning of the SQL statements are complex, the SQL of the heterogeneous database basically conforms to the SQL99 standard, but the SQL statements are different in partial extension implementation, and the SQL statements in the project codes cannot be directly matched due to different business logics or code architectures.
Step five: and the report generating module summarizes the data result of the analysis code analyzing module and generates an HTML report.
