摘要
En 中文
As software continues to evolve and business functions become increasingly complex, architectural inconsistency arises when the implementation architecture deviates from the expected architecture design. This architectural problem makes maintenance difficult and requires significant effort to refactor. To assist labor-intensive refactoring, automated refactoring has received much attention such as searching for optimal refactoring solutions. However, there are still three limitations: The recommended refactorings are insufficiently effective in addressing architectural consistency; the search process for refactoring solution is inefficient; and there is a lack of executable refactoring solutions. To address these limitations, we propose an effective, efficient, and executable refactoring recommendation approach namely the 3Erefactor for software architectural consistency. To achieve effective refactoring, 3Erefactor uses NSGA-II to generate refactoring solutions that minimize architectural inconsistencies at module level and entity level. To achieve efficient refactoring, 3Erefactor leverages architecture recovery technique to locate files requiring refactoring, helping accelerate the convergence of refactoring algorithm. To achieve executable refactoring, 3Erefactor designs a set of refactoring executability constraint strategies during the refactoring solution search and generation, including improving refactoring pre-conditions and removing invalid operations in refactoring solutions. We evaluated our approach on six open source systems. Statistical analysis of our experiments shows that, the refactoring solution generated by 3Erefactor performed significantly better than 3 state-of-the-art approaches in terms of reducing the number of architectural inconsistencies, improving the efficiency of the refactoring algorithm and improving the executability of refactorings.
