This is a tool that uses java object-oriented idea to write and generate SQL statements. On this basis, it also implements lightweight plug-in support similar to JPA for mybatis and spring JDBC. A large number of common SQL execution methods are built in plug-ins to improve development efficiency, reduce a large number of SQL statement writing, and make developers focus on business code writing.

The newest version!
