How Spring Controls transactions

Spring's transactions, which can be said to be an implementation of spring AOP.

AOP is oriented to slice programming, that is, without modifying the source code, the original function is extended, through the proxy class to operate on the specific class.

Spring is a container that manages objects through the spring container and implements spring's management of objects according to the configuration file.

Spring's transaction declarations are available in two ways, programmatic and declarative. Spring mainly manages transactions through "declarative Transactions," which are declared in a configuration file, and the biggest benefit of using AOP to cut a transaction slice into a program is to significantly reduce the amount of code.
