Springmvc+spring+hibernate to build an example

This article is based on this blog post, the original text here http://blog.csdn.net/bjyfb/article/details/8998267 1. Description

Build Springmvc+spring+hibernate framework, the project structure as shown in Figure 1

The referenced jar package is Spring3.2.6 and Hibernate4, as shown in Figure 2
2. configuration file 2.1 spring-mvc.xml

Pay attention to the contents of the annotation, write a more detailed
