Problems solved by technology

The current research on the directional architecture recovery of layered patterns is mainly based on the structural dependencies between program entities, that is, layered pattern recognition is performed directly on the program dependency graph, which ignores the fact that layered patterns are mainly used for separation of concerns in the system characteristics, resulting in a large gap between the restoration result and the actual level of the target system

Embodiment 1

[0057] Embodiment 1: For the convenience of description, the present invention takes the identification process of the spring-petclinc open source project as an example, and further introduces the present invention in conjunction with the accompanying drawings and specific implementation methods.

[0058] Step 1) Obtain the keyword set W corresponding to the 6 packages in spring-petclinic and the dependency relationship set E between program entities by statically analyzing the program source code. The specific process includes:

[0059] (11) Convert the source code of the target system into an AST abstract syntax tree structure through the static code analysis tool JDT;

[0060] (12) Traversing the AST tree nodes, extracting the vocabulary of the corresponding position in the source code file and the dependency relationship between classes from the nodes;

[0061] (13) Utilize regular expressions to extract the words contained in the comments that the AST tree cannot obtain; ...

Abstract

The invention provides a hierarchical architecture identification method based on code vocabularies and structural dependence, which comprises the following steps: extracting key vocabularies in a source code to perform responsibility clustering, and performing software system hierarchical identification by utilizing dependence among program entities; the characteristics of the hierarchical mode and the application scene are combined, the recognition precision is higher, and a recognition result can help a designer understand the existing state of the system more easily.

Description

technical field [0001] The invention is a layered architecture identification method based on code vocabulary and structure dependence, and is mainly used for reversely performing system layered structure recovery in the case of architecture offset and missing documents. Background technique [0002] The software system will become more and more complex as it evolves, but the system architecture information is not updated and documented in time, which causes the architecture of the existing software system to deviate from the original architecture over time. The lack of architectural information and architectural deviation will become more and more serious as the system evolves. If the software architecture or structural complexity cannot be effectively controlled, it will eventually lead to the end of the software system life cycle and cannot continue to evolve. In order to solve this kind of problem, the industry often adopts the method of architecture recovery to obtain t...
