In some cases, the JDK used in our engineering is not necessarily more than 1.5, which means that annotation annotations may not be supported by nature, and it is not possible to use @aspectj annotation-driven AOP, so if we still want to use AspectJ flexible pointcut expressions, So what should we do? Spring provides us with an AOP namespace based on XML schematic, which is used in the same way as @aspectj annotations, unlike configuration information

Spring Loose Coupling exampleThe idea of object-oriented design is to divide the whole system into a set of reusable components, however, when the system gets bigger, especially in Java, the biggest object dependency will be tightly coupled so that it is very difficult to manage and modify, and now you can use the spring framework to play the role of an intermediate module, Easy and efficient management of

The main difference between this example and the above example is that the implementation class of DOA inherits from sqlsessiondaosupport. In fact, even if we do not inherit the sqlsessiondaosupport class, we will define a parent class to provide sqlsession member variables and the corresponding getter/setter. Otherwise, when there are more implementations of DOA, every implementation class writes this proc
