##  springmvc的配置文件springmvc.xml：
    <!-- 配置扫描器 扫描使用注解的包： -->
    <context:component-scan base-package="页面数据封装与回显"></context:component-scan>
    <!-- 配置注解开发的控制器映射器和控制器适配器  使用mvc:annotation-driven标签可以一键配置适配器和映射器 -->
    <mvc:annotation-driven/>

controller控制类(类上加了controller注解 类中其他方法以.do后缀的访问路径可以访问)：

@RequestMapping("/test/bb")
public String submitUserMap(String name) {
System.out.println("aa");
return "/success.jsp";
}
