Hibersafe: um sistema de recomendação baseado no StackOverflow para Bugs do Hibernate relacionados a exceções

Abstract

Hibernate is a popular Java framework used to support data persistence through object relational mapping. This mapping is accomplished through the use of Java annotations. The way these annotations are processed, however, is not easy to understand by most developers using this framework. In addition, we are faced with a lack of documentation related to exceptional behaviors that occurs with the use of these annotations. This work seeks to provide means to help developers better understand and fix bugs related to exceptions that may arise when using Hibernate annotations. In the proposed approach, the knowledge of the crowd knowledge provided by Stac-kOverflow - in this case, questions and their answers about Hibernate - is used by a tool, called Hibersafe, which aims to help developers to find solutions for Hibernate exception related bugs. We compared the Hibersafe tool with the usual approaches (i.e., developers using Google or StackOverflow search engine). Our tool proved to be more efficient in the evaluated scenarios when compared to these usual approaches. Thus, this study showed that Hibersafe can be used as recommendation system for bugs related to Hibernate exceptions.
