1. 导入相关jar包。
2.完成spring的相关配置
1） 在web.xml中完成spring的声明
contextLoaderListener的配置，如果是location，那么配置文件必须放到web项目的根目录中。
如果是放到类路径下，需要改为classpath：applicationContext.xml
2）新建spring的配置文件
这个名称必须与web.xml中，配置的一致。如applicationContext.xml
3.完成springMVC的配置
1）在web.xml中，配置dispatcherServlet，在location中，需要改为classpath类路径下，url改为/，
2）新建一个springMVC的配置文件，建立在类路径下，导入相关的命名空间，如beans，mvc，context。
自动扫描，注解生效，默认处理机。至少配置这3个。<context component-scan base-package="cn.taotao.*"/>必须写包名，不能是*，否则报bean无法初始化注解错误
<mvc:annotation-driven /><mvc:default-servlet-handler/>
配置视图的解析器，internalResourceViewResolver,配置前缀，prefix, 和后缀名 .jsp
代码如下：

applicationContext.xml，开始的时候，不用做任何修改只要有这个文件即可。

spring-mvc.xml，扫描包的时候，不能用*，必须加包名，否则报bean注解无法初始化错误
