To learn more about starting a transaction with spring, let's take a look at this simple example:1. entity class user. Java Package Org. lab24.entity; 2. Abstract DAO class. Here it is set as an abstract class mainly to prevent it from directly instantiating objects (this design seems a bit redundant here. This should be a design pattern ): Package Org. lab24.dao; 3 DAO implementation class: Package Org
