一、总结
1.web项目一定要把引用的jar包放在WEB-INF/lib下(common-logging1.2,spring4.1.6所有包，其实不需要那么多，懒得筛选了,)
2.web.xml中要初始化servlet配置文件，如*-servlet.xml
3.显示声明处理器映射为org.springframework.web.servlet.handler.SimpleUrlHandlerMapping，默认的BeanNameUrlMapping尝试未成功。
二、环境环境
1.我的开发环境（windows+EclipseJee+tomcat6+jdk6），不同的同学可以忽略
2.项目路径图：
三、代码：
