<context:annotation-config />这个配置告诉springmvc,springmvc相关的bean中使用注解来进行表示

<context:component-scan base-package=\"com.jlh2.study.web.module\"/>这个配置告诉springmvc对com.jlh2.study.web.module进行扫描，并创建其中的javaBe an并注入到spring容器中。

<bean class=\"org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping\" /> 启动springmvc的注解映射功能

<bean class=\"org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping\" /> 自动将访问url映射到同名的Controller上面

<bean class=\"org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter\"/> 启动springmvc的注解功能
