In addition, there are many common parts in our application, such as logging, exception processing, database transaction processing, etc. can be implemented by AOP. Imagine every business method has to write calls logging, exception processing code, we developers will be tired. By implementing AOP through unity, these common code is extracted from every business method, making our c
