As a persistent layer framework frequently used in China, MyBatis has excellent internal code design. For example, in the development process, having the ability to carry out in-depth customized development of the framework, solving BUG is also more handy! In addition, learn how developers design high-scalability, low-coupling code for easy application in their own development scenarios.
And MyBatis is the content that must be asked in the interview when changing jobs, so how much do you know about MyBatis? I want to learn MyBatisK, but there are too few MyBatis materials on the market that are really suitable for learning. Although some books or materials are more in-depth, the language is difficult to understand. Most people read these books from getting started to giving up. Is there really no one method that suits most students after learning the MyBatis source code?
In this sharing a work of more than ten years Ali Gangster sorted out, "the source MyBatis study documents" , this document analyzes Mapper binding process from the perspective of MyBatis source, SqlSession operation database theory, principles and other plug-in implementation, streamlined and easy to understand , It's much better than the books and materials on the market that are always very long.
