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 with reference to the accompanying drawings and specific implementations.

[0058] Step 1) Obtain the keyword set W corresponding to 6 packages in spring-petclinic and the dependency relationship set E between program entities by statically analyzing the program source code, and 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) Traverse the AST tree nodes, and extract the vocabulary of the corresponding position in the source code file and the dependencies between classes from the nodes;

[0061] (13) Using regular expressions to extract the vocabulary contained in the annotations that cannot be obtained by the AST tree;

[006...

Abstract

The present invention proposes a layered architecture recognition method based on code vocabulary and structural dependencies, which extracts key words in source codes to perform responsibility clustering, and then utilizes dependencies between program entities to identify software system levels; The characteristics and application scenarios of the layer mode, the recognition accuracy is higher, and the recognition results are easier to help designers understand the current state of the system.

Description

technical field [0001] The present invention is a layered architecture identification method based on code vocabulary and structure dependency, which is mainly used for the problem of reverse system layered structure restoration in the case of architecture deviation and missing documents. Background technique [0002] Software systems will become more and more complex with the evolution process, but the system architecture information is not synchronized and documented in a timely manner, which leads to the fact that the architecture of existing software systems often deviates from the original architecture over time. The lack of architectural information and the problem of architectural deviation will become more and more serious with the evolution of the system. If the software architecture or structural complexity cannot be effectively controlled, the life cycle of the software system will eventually come to an end and cannot be continuously evolved. In order to solve suc...
