Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The code generation method provided by the application can be applied to the application environment shown in fig. 1. Wherein the terminal 102 communicates with the server 104 via a network. The terminal 102 is configured to provide a user operation interface, monitor an object to be operated specified by a user, monitor configuration operations of the user, and send a code generation request to the server 104. The server 104 extracts the metadata of the object to be operated, loads at least one group of code templates matched with the metadata, and combines the metadata and the code templates to generate codes of at least one operation type of the object to be operated. The terminal 102 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and the server 104 may be implemented by a stand-alone server or a server cluster composed of a plurality of servers.
In one embodiment, as shown in fig. 2, a code file generation method is provided, which is described by taking the application of the method to the server in fig. 1 as an example, and includes the following steps:
step S202: and acquiring metadata of the object to be operated.
The object to be operated can be a web page, an interface or a class and other program units which have relatively solidified properties and can be further operated. Metadata of an object to be operated on refers to data used to describe the properties of the object. For example, the metadata of an http interface may include interface paths, input and output parameters of the interface, and the like. The metadata of the web page may be a component id, a component type, and the like.
And scanning the source code of the object to be operated, and extracting metadata from the source code of the object to be operated. For example, JAVA engineering, by loading a class file of an object to be operated, traversing a class method (method) and a class variable (field) in the class file to obtain metadata describing the attributes in the class file.
Step S204: and loading at least one group of code templates matched with the extracted metadata, wherein each group of code templates defines the set operation logic of the object to be operated.
Abstractions code templates for manipulating various types of objects are defined for various types of manipulation logic that may be implemented for various types of objects to be manipulated. The operation logic is an abstracted operation method framework, and one type of operation logic is essentially codes capable of implementing setting operation on the same type of objects to be operated. If the operation code for implementing the call operation on the http interface is the interface call code template, the http interface is called by the user.
In this embodiment, a plurality of code templates are defined for the object to be operated, and each code template implements an operation logic of the object to be operated. If the object to be operated is an interface, the code template defined for the http interface may be a code template for calling the interface, a code template for encapsulating the interface, or the like. Combinations of multiple code templates for the same object may also be used to implement an operating logic.
In one embodiment, a tag matching an object may be added to each defined code template, and the loaded code template is a code template with a tag of an object to be operated. In another embodiment, a matching degree between the extracted metadata and the replaceable content in the code template may be calculated, and it is determined whether the code template is suitable for performing a corresponding operation on the object to be operated according to the matching degree. And the user can select the code template which needs to be loaded currently in a manual configuration mode.
In this embodiment, the loaded group code template matching the metadata may include one code template or a plurality of code templates, and one or a combination of one or a plurality of code templates can implement one operation logic of the object to be operated. Loading a set of code templates means loading a set of code templates that implement an operating logic. The embodiment focuses on loading multiple groups of code templates, and the multiple groups of code templates can realize multiple types of operation logics of objects to be operated.
Step S206: and combining the loaded code template with the metadata to generate at least one code file for operating the object to be operated.
The template engine replaces the template content of each set of loaded code templates by using the metadata of the object to be operated, and each set of code templates after replacement can realize the set type operation logic of the object to be operated.
In this embodiment, by scanning an object to be operated, extracting metadata capable of describing attributes of the object, and loading one or more sets of code templates capable of being combined with the metadata, each set of code template may implement a specific type of operation on the object to be operated, and combining the metadata and the code templates, codes of various types of operation logics for the object to be operated may be generated. The method and the device can generate codes of various operation types of the objects to be operated in batches, and the generated codes can be flexibly customized according to needs. The code template matched with the object to be operated can be combined in a customized mode to derive a plurality of operation logics of the object to be operated.
In addition, by abstracting the code logic for a certain type of object to be operated, a large number of repeated knocks of the code in the development process is reduced.
In one embodiment, step S202: the acquiring metadata of the object to be operated comprises the following steps: acquiring a source code file of an object to be operated; analyzing the source code file, and determining a data extraction strategy corresponding to the source code file according to a corresponding relation between a pre-configured source code file type and the data extraction strategy; and loading the determined data extraction strategy, and extracting the metadata from the source code file of the object to be operated through the data extraction strategy.
Furthermore, the request can carry the identifiers of a plurality of objects to be operated, and the server loads corresponding extraction strategies for the plurality of objects to be operated in a multithreading mode and extracts the metadata of the plurality of objects to be operated at the same time.
As shown in fig. 3, the server loads two types of source code files of the object to be operated, such as a java.class file (class file) and an Html file, loads a path policy, a Method policy and a param policy configured for the java.class file in advance, loads a component policy configured for the Html file in advance, extracts and outputs metadata of the object to be operated through the loaded policy, and the output metadata is used for matching with the matched code template.
In this embodiment, different extraction strategies are defined for different types of objects to be operated, and when metadata of the objects to be operated is extracted, the extraction strategies are directly called, so that the metadata can be automatically extracted. Metadata of different types of objects to be operated can be extracted simultaneously by calling a blind extraction strategy, and the data extraction efficiency is improved.
In one embodiment, as shown in FIG. 4, step S204: loading at least one set of code templates matching the metadata, comprising the steps of:
step S402: and calling at least one template processor according to the type of the metadata, wherein the template processor is a loader for setting the code template combination.
Step S404: the corresponding code template combination is loaded by the template processor.
A plurality of template processors are predefined, and code template combinations which can be loaded by each template processor are specifically defined. Each template processor is configured with a loadable combination of code templates, and the template processor is essentially a loader that sets the combination of code templates. And establishing an association relation between the template processor and the metadata type through a code template combination which can be loaded by the template processor and the metadata type which is adapted to the code template in the code template combination. The specific implementation method comprises the following steps: and calling at least one template processor according to the type of the metadata, and loading the code template combination which can be loaded by the template processor. The multiple code templates loaded by the same template processor can realize one operation logic of the object to be operated and also can realize a series of related operation logics of the object to be operated.
In the embodiment, by defining the template processors, all the code templates matched with various objects to be processed can be combined and classified in advance, and the server can load the code templates according to the predefined combinations only by searching the matched template processors according to the types of the metadata without performing complicated code template combinations.
For example, the code templates matched with a certain type of object to be operated include a code template a, a code template B and a code template C, wherein the combination of the code template B and the code template C, and the combination of the code a, the code template B and the code template C can also realize a type of operation on the object to be operated, then 5 template processors may be defined, and the 5 template processors are defined to be sequentially the code template a, the code template B, the code template C, the combination of the code template B and the code template C, and the combination of the code a, the code template B and the code template C. Of course, if there are other combinations that can also implement operations on the object to be operated, more template processors are defined. Adding corresponding metadata type tags for defined template processors, wherein one template processor can correspond to a plurality of metadata type tags.
In one embodiment, as shown in FIG. 5, step S306: the loaded code template and the metadata are combined to generate at least one code file for operating the object to be operated, and the method comprises the following steps:
it should be noted that the following steps are given as logic for combining the metadata with one or a group of code templates, and the combination of the metadata with the multiple groups of code templates can be realized by circularly executing the following steps, or the simultaneous combination of the metadata with the multiple groups of code templates can be realized by executing the following steps in a multithread way.
Step S502: the metadata is converted into a set of key-value pairs, the key-value pairs including variables and variable values.
The metadata is converted into a ("key value") string, key being a variable and value being a variable value.
Step S504: and acquiring a directory of the code template, and replacing variables of directory sub-items in the directory with variable values in the metadata.
Recursively traversing all sub-items in the directory of the code template, judging whether the currently traversed sub-items are files or directories, if so, searching whether variables exist in the directory, if so, searching whether variable values corresponding to the variables in the directory exist in the metadata, and if so, replacing the variables in the directory with the corresponding variable values until the variables of the sub-items of each layer of the directory of the code template are replaced.
If the template directory carries $ { var } variable characters, the converted metadata is context.
Step S506: and generating the package name according to the directory sub-entry of the code template directory after replacing the variable.
Step S508: and acquiring a code template file, replacing the content in the file with metadata, generating a code file, and declaring the generated package name by the generated code file.
The code template directory comprises directory sub-entries and file sub-entries, and after variables in the directory sub-entries are replaced by variable values of the metadata, package names are generated according to set rules based on the directory sub-entries of each layer of the code template.
The file sub-item in the code template directory designates a code template file, the template engine replaces the content in the code template file with metadata, and removes the blank lines and annotations in the template to generate the code file.
In this embodiment, a package name is generated according to a directory sub-entry of the template directory, a code file is generated according to a file sub-entry in the template directory, and the generated package name is declared by the code file. When generating code, declaring a package name for the generated code file, namely creating a new namespace for the class in the code file by using the package name, and because the package creates a new namespace (namespace), no naming conflict with any name in other packages can be generated. Using a package mechanism, access control is easier to implement and locating related classes is simpler, and without using such a package mechanism declaring a package name for a newly generated code, an editing error will occur.
In one embodiment, when extracting the metadata of the object to be operated, the package name prefix is configured for the metadata. The system identifier of the system where the object to be operated is located may be searched, and the system identifier of the system where the object to be operated is located is configured as a package name prefix of the metadata of the object to be operated. And adding a package name prefix into the generated package name.
For example, the template catalog of the code template is: templates/app/appller.java, wherein/app/is a directory sub-item, and appller.java is a file sub-item, and if the configured package name prefix is com. And loading a template file based on the file sub-item, combining the template file and the metadata to generate a code file, wherein the package name corresponding to the code file is com.
When the loaded group of code templates comprises a plurality of code templates, a plurality of code files are generated according to the steps S502-S508, and each code file generates a package name correspondingly. The directory of the generated code file includes its corresponding package name.
It should be understood that although the various steps in the flowcharts of fig. 2, 4-5 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 2, 4-5 may include multiple sub-steps or multiple stages that are not necessarily performed at the same time, but may be performed at different times, and the order of performance of the sub-steps or stages is not necessarily sequential, but may be performed in turn or alternating with other steps or at least some of the sub-steps or stages of other steps.
In one embodiment, in step S508: acquiring the file of the code template, and replacing the content in the file with metadata to generate a code file, wherein after the generated code file declares the package name generated according to the code template directory, the method further comprises the following steps: and judging whether the generated code file exists or not, and if so, combining the code file.

The method comprises the steps of firstly obtaining an existing code file and a new code file, converting the existing code and the new code into a syntax tree by using an Eclipse JDT library, loading a configured merging strategy and circularly executing the merging strategy to generate a merged syntax tree, converting the merged syntax tree into a code text, and writing the code text into a target code file.
In one embodiment, a directory and a merge of directories are also included. The method specifically comprises the following steps: and judging the type of the merging source, namely merging the directory and the directory or merging the file and the file. If the files are merged, the merging method shown in fig. 6 is adopted for merging.
