Preface
MyBatis is an excellent persistence layer ORM framework. It encapsulates the process of jdbc's database operation, so that developers only need to pay attention to SQL itself, instead of spending energy on processing such as registering drivers, creating connections, creating statements, and manually setting parameters , Result set retrieval and other jdbc complicated process code.
If you are not familiar with the use of MyBatis, please refer to the official MyBatis document first, which is of great benefit to understanding its architecture design and source code analysis.
Recently, a MyBatis source code interpretation document has become popular on GitHub. It is regarded as the most in-depth MyBatis source code interpretation in the entire network. It is summarized by a certain line of architects. Ten years of development experience, I believe it is here. The information is ready, ready to receive benefits!
