spring, springMVC, shiro build the framework.

1. Import Related jar package.

2. Complete the spring of configuration

　　contextLoaderListener configuration, if it is location, then the configuration file must be placed in the root directory of your web project.

If classpath, it is necessary to classpath: applicationContext.xml

The name must web.xml, the configuration of the same. As applicationContext.xml

2) springMVC a new configuration file, based on the classpath, import the relevant namespace, such as beans, mvc, context.

Automatic scanning, annotations take effect, the default processor. Configure at least three. <Context component-scan base-package = "cn.taotao. *" /> Package name must be written, can not be * Otherwise, the frame could not be initialized bean annotation errors

<mvc:annotation-driven /><mvc:default-servlet-handler/>

View configuration parser, internalResourceViewResolver, configured prefix, prefix, and suffix .jsp
