Today, I will talk to you about the analysis of the use of duboo. Many people may not know much about it. In order to make you understand better, the editor has summarized the following contents for you. I hope you can get something according to this article.

I. background

With the development of the Internet and the continuous expansion of the scale of website applications, the conventional vertical application architecture has been unable to cope with, distributed service architecture and mobile computing architecture are imperative.

As more and more interfaces and implementation classes increase, there will be more and more xml configuration for duboo. In order to prevent hundreds of thousands of lines of code, reduce the workload of developers configuring xml, use duboo's annotation mode, and reduce the possibility of configuration problems!
