I have written an article about the reconstruction of the command module: OEA autoui reconstruction (1)-Automatic Command generation. Command auto-generated refactoring is a "Forward war" of This refactoring. We try to use OO to optimize the original process-based interface auto-generated process to support better scalability. The Automatic Generation of commands is relatively independent, so the reconstruction is performed independently. At present, the reconstruction has been completed and the
