According to the embodiment of the disclosure, by determining the template file of the target project, inputting the metadata into the template file, and automatically generating the target project, the technical problems that the database model is not standard and the project is repeatedly and fussy to build due to the adoption of a mode of manually designing the database model and newly building the project structure in the related technology are at least partially overcome. For example, the problems of non-standardization, non-consistency and repeated fussy basic work in the process from database design to project code writing of developers in WEB system development built by a Maven and SSM framework can be solved. Where Maven is a project building and management tool. The SSM framework is an abbreviation of Spring + Spring MVC + MyBatis, is a current mainstream Java EE enterprise-level framework, and is suitable for building various large-scale enterprise-level application systems.
FIG. 2 schematically shows a flow diagram of a project generation method according to an embodiment of the present disclosure.
As shown in fig. 2, the method includes operations S210 to S240.
In operation S210, a configuration file is acquired, wherein the configuration file includes configuration information for generating a target item.
In operation S220, metadata is acquired from the target database according to the configuration information in the configuration file.
In operation S230, a template file of the target item is determined.
In operation S240, metadata is input into the template file, and a target item is generated.
According to the embodiment of the disclosure, the configuration file can be read by the code generator, and the metadata is obtained from the target database according to the configuration information in the configuration file. According to the embodiment of the disclosure, the metadata can be further processed, then the maintained template root directory is recursively traversed, corresponding processing logic is realized through different template file types, the metadata is input into the template file, the target code is generated and output to the specified path, and the generation of the project code is completed.
According to an embodiment of the present disclosure, the configuration information for generating the target item may include various kinds, for example, may include, but is not limited to, the following information: 1. a database source: the method comprises five attributes including database drive, address, port, database name, user name and password, wherein metadata is read through a data source and processed, and the association relationship among a table, a field and field enumeration is stored at the same time, and the processed attributes are as follows: table: table name, table remark, table object name, table class name; field: database column names, Java names, capital letters of Java names, remarks, JDBC types, Java types, simplified remarks, whether enumeration is performed, the maximum length is performed, and whether the remarks are empty or not; field enumeration: enumerating the described Chinese pinyin letters, capitalizing underlines, enumerating numerical values and enumerating description. 2. Inclusion and exclusion of table names: the method comprises the steps of including table names and excluding table names, determining a table which is generated and not generated according to the two configurations of the table names separated by English commas, including all the table names if the included table names are null, not excluding the table names if the excluded table names are null, and having exclusion priority higher than the included table names. 3. Item-related configuration: the system comprises three attributes of groupId, artifactId and projectName, wherein the groupId represents a developer ID, the artifactId represents a project name and is used for constructing a maven project, determining an output path and generating a package name, and the projectName represents the project name and is used for managing background display. sysModules: the lower case letters are underlined, the characters are not more than 40 at most, English commas are separated, the service is defaulted, if the attribute is configured, a specified number of interface service subsystems are generated, the interface service is often used for the detailed splitting of the interface service, for example, in order to reduce the influence of the service interface on the interaction with a fund company, the fund front end can be split and configured into the service, and the fund front end is a function-front. Servlet 3: if true, then servlet3 will be introduced, actually subject to the container. Output folder: output folder, support D: the form of \ \ gen and/gen. 7. Generating a strategy: when the target file is generated, if the target file does not exist, the target file is uniformly generated. For the case where a target file exists, there are three parameters that can control the generation policy. Forcedly generated target files, forceGenerateFiles, separated by english commas, are often used to cover target generated files; if the generation is not repeated, isReGenerator, true will only cover the file involved in the generation table field modification; IsoOverWrite, true, or false, valid when isReGenerate is not true, indicates whether the target file is overwritten, and is not overwritten by default. An author: and (4) a project author notes the generated code. According to the embodiment of the disclosure, the new project is generated by using the template file of the target project, the configuration file, the code style and the frame structure are maintained uniformly and stably and available, the generation can be directly deployed and operated after the completion, and a series of complex work of newly building the project every time is avoided. Meanwhile, the template can be adjusted according to actual conditions, and the general solutions and tools in the original project are continuously maintained in the template, so that the improved accumulation of the project can be directly used in a new project. The method can solve the problems that the manual project creation is complicated, low in efficiency, different in style, easy to make mistakes, and new projects are manually moved in the original solution, tools and the like.
According to the embodiment of the disclosure, because a technical means of automatically generating the target project by determining the template file of the target project and inputting the metadata into the template file is adopted, the technical problems that the database model is not standard and the project is repeatedly and fussy due to the fact that the database model is artificially designed and the project structure is newly built in the related technology are at least partially solved, and further the technical effects of automatically generating the target project and improving the project generation efficiency are achieved.
The method shown in fig. 2 is further described with reference to fig. 3-6 in conjunction with specific embodiments.
FIG. 3 schematically illustrates a flow diagram for obtaining metadata from a target database according to configuration information in a configuration file, according to an embodiment of the disclosure.
As shown in fig. 3, acquiring metadata from the target database according to the configuration information in the configuration file includes operations S221 to S223.
In operation S221, in the process of obtaining metadata from the target database, it is determined whether the structural design of the target database satisfies a preset rule.
In operation S222, in a case where it is determined that the structural design of the target database does not satisfy the preset rule, the prompt information is displayed.
In operation S223, in case that it is judged that the structural design of the target database satisfies the preset rule, the metadata is acquired.
According to the embodiment of the disclosure, in the process of acquiring metadata from the target database, if the code generator finds that the database design does not meet the preset rules, for example, the database, the table and the field names are not in the form of lowercase underlines, have no remarks, have default fields and the like, the code generator prompts and quits, and ensures that developers find and modify in time.
According to the embodiment of the disclosure, after tables and fields in the database are newly added and modified, the database structure and the codes can be ensured to be consistent through regeneration, and the problems of manual maintenance omission and errors are avoided.
Through the embodiment of the disclosure, when the metadata is read, if the database design is found to be out of specification (if the database, the table and the field names are not in a form of underlining of a lower case letter, and no remarks are made), the user is prompted, and developers can be ensured to find and modify in time; after tables and fields are newly added and modified, the structures and codes of the database can be ensured to be consistent through regeneration, so that modifications such as database model, enumeration and the like can be timely and accurately synchronized with the codes, and the problems of manual maintenance omission and errors are avoided.
FIG. 4 schematically shows a flow diagram of a project generation method according to another embodiment of the present disclosure.
As shown in fig. 4, the method includes operations S250 to S270.
In operation S250, before inputting metadata into a template file and generating a target item, a type of the template file is determined.
According to the embodiment of the disclosure, the metadata is input into the template file, the new project is generated by using the project template, the configuration file, the code style and the frame structure are maintained uniformly and stably and available, the generation can be directly deployed and operated after the generation is completed, and a series of complex work of newly building the project every time is avoided.
In operation S260, an input policy of metadata is determined according to the type of the template file.
In operation S270, metadata is input into the template file according to the determined input policy.
According to the embodiment of the disclosure, in the process of inputting the metadata into the template file, since the regenerated project may cover the original modification (generally, business SQL Mapper), a custom code block may be added into the template, the content of the target modification may be put into the custom part, the target custom part is read before the coverage and is filled into the template, and then the error coverage is ensured, and the function that the newly generated target file can retain the modification in the old target file is realized by using the custom code block.
According to an embodiment of the present disclosure, the input policy may be the following policies: 1. all tables are merged: merging the data of all tables needed by the template, and managing the left column of the background and the home page; 2. and (3) single table merging: when the template generates a target file, all table information needs to be traversed to generate a corresponding target file which is used for an entity class, a database access layer, a transaction management layer, a service layer, a controller layer, a background page and the like; 3. table field merging: the enumeration needs to generate a target enumeration class according to the dimensions of a table and a field, and one enumeration description is equivalent to one enumeration in the enumeration class; 4. merging of single files: for configuration files and common Java classes of some SSMs, filling database configuration, package names and the like; 5. single file replication: the method can be a default processing mode and is commonly used for the resource files, and only the vm suffix needs to be removed and copied to the target path.
According to the embodiment of the disclosure, the target project may include one or more target files, and the generation policy of the target files may be determined according to the type of the template file.
For example, jquery. js.vm, the template type determines that metadata does not need to be input, and the metadata is copied to a target path to generate jquery. js; vm determines the metadata required to be input to each table, and outputs a target file of table0dao.xml, tablel dao.xml tablel 2 dao.xml.
According to the embodiment of the disclosure, the framework of the template file comprises a service terminal subsystem, a user foreground subsystem, an operation background subsystem and a common component subsystem.
Fig. 5 schematically shows a schematic diagram of the architecture of a template file according to an embodiment of the present disclosure.
As shown in fig. 5, the system of generated target items may generally include a service subsystem, a user foreground subsystem, an operator background subsystem, and a common component subsystem. The user foreground subsystem is used for interacting with a front-end page of a user and is independent of a database; the service terminal system provides a service interface for the foreground and bears user services; the operation background subsystem is used for operation background management; the public component subsystem is provided for the service terminal subsystem, the user foreground subsystem and the operation background subsystem in a dependent mode, and repeated maintenance is avoided.

The SQL Mapper is used for applying an XML mapping file for accessing a database in Mybatis and generating and executing SQL in an SQL splicing mode.
According to the embodiment of the present disclosure, the enumeration of the entity class may be automatically generated through metadata, and only the code needs to be regenerated after the modification, and the enumeration information is obtained by analyzing the remark in a specific format, for example, there is a field state in the order table order, and the remark is: the order status, 1, unpaid, 2, paid, is resolved into an enumeration class of order status, EmOrderState, and the enumeration therein is represented by pinyin underlining, such as WEI _ zuhifu (1, "unpaid"), YI _ zuhifu (2, "paid"), that is, if the enumeration class is modified, only the database remarks need to be modified and then regenerated. According to the embodiment of the disclosure, the project entity class, enumeration and SQL Mapper can be synchronized by reading metadata; generating a new item using the template item; and the entity class, enumeration, a database access layer, SQL Mapper, a transaction layer and a service layer are combined and generated according to a table.
Usually, the default field of a table contains id (primary key), mark (remark), created _ time (creation time), modified _ time (modification time), yn (valid or not, logical deletion identifier), and the default field is written into a fixed value in the SQL Mapper for automatic generation, so as to mask the damage of the application to the data. If the time is written, establishing time, and if the time is modified to be the current time, whether the effective write is dead or effective; the modification time is set as the current time during updating, the condition that whether the adding is effective or not is used for preventing the access to the logically deleted data, the condition that whether the deleting (logical deleting, actually updating) is effective or not is also used for defaulting the adding to be effective, and whether the updating field is dead or not is invalid or not, so that the system risk is shielded on the SQL level.
Generating SQL Mapper, and providing a writing object by default by the system; writing the object and writing the database id back to the object; writing in batches; pressing an id primary key for updating; updating by condition (supporting expected influence line number); querying according to id; querying the list according to the condition; inquiring the record number according to the condition; selecting one bar (whether null can be accepted or not) according to conditions; selecting a unique record (whether null can be accepted or not) according to conditions; paging query; pressing an id primary key for logical deletion; the method of deleting according to the condition logic (supporting the expected influence line number) and the LIKE comprises all basic single table operations, and almost all business processing can be completed and SQL writing by developers is not needed through the expanding Map of the object, the supporting IN (main key and enumeration), the LIKE (character string) and the query of time (date type, date larger or smaller than the specified date).
Through the embodiment of the disclosure, the template file is divided into a plurality of subsystems, so that each part of the template can be adjusted according to actual conditions.

According to the embodiment of the disclosure, the service subsystem and the user foreground subsystem can be generated in addition to the background management page of the target project based on the template file generation. The template engine can adopt a Velocity template engine, and the output display and logic control of variables can be performed by analyzing the placeholder and the markup language of the template, so that page rendering is realized.
According to the embodiment of the disclosure, the background management page can be divided into a list, an editing page and a detail page, the three pages can be obtained through consistent interfaces through analysis, the data can be taken and displayed by writing in corresponding interfaces when different tables are combined with a template, and different UI components are introduced by judging the type, enumeration, time, character string, number and the like of a field during generation, so that the repeated labor of the page is avoided. According to the embodiment of the disclosure, the macro definition and the enumeration class of the pre-loading metadata of the template engine are combined, and the metadata of the table and the field are also combined. For example, one field is time type, then time component is used; a field string type, is presented using an input box.
Through the embodiment of the disclosure, through preloading enumeration classes and combining macro definition of template engine Velocity, values can be directly taken and pull-down can be displayed on an interface, such as order state fields, and the pull-down box can be translated and displayed without binding enumeration and iteration.
