In learning Spring, we know that Spring has two main ideas, one is IoC, the other is AOP. For IoC, dependency injection needn't be said much. For Spring's core AOP, we not only need to know how to satisfy our functions through AOP, but also need to learn the underlying principle, and the principle of AOP is the motive of java. The state proxy ...
