Spring+MyBatis框架搭建
引入包：
spring:http://repo.spring.io/libs-release-local/org/springframework/spring/4.2.1.RELEASE/spring-framework-4.2.1.RELEASE-dist.zip
Apache Commons Logging 1.2: http://apache.fayea.com//commons/logging/binaries/commons-logging-1.2-bin.zip
web.xml配置：
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>servlet-name非常重要，默认情况下DispatcherSerlvet会自动尝试读取WEB-INF目录下名为servlet-name-servlet.xml的文件来加载应用程序上下文，这里对应的就是WEB-INF目录下的dispatcher-servlet.xml，如果配置
了contextConfigLocation（名字貌似是固定的）参数，设置上下文配置文件路径，自搭建为classpath:springmvc.xml，如果此参数不设置，默认加载WEB-INF路径下的application-Context.xml文件。
