Spring mvc-Associated Source codeFirst of all, why do we want to associate the source code:　　In fact, I think reading the source code is a very good way of learning, in our daily work will be more or less exposed to some open source, such as the most popular struts, Hibernate, spring these frameworks of the source. These excellent source code has accumulated in the essence of many years, is very worthy of our study, no matter what level we are at present, through the repeated reading of the sour
