多么痛的领悟----(码农的低级错误)

(2017-7-23)

问题描述:

　　页面url请求发出后,显示404; 控制台debug:

p.p1 { margin: 0.0px 0.0px 0.0px 0.0px; font: 14.0px Monaco }

[DEBUG] Last-Modified value for [/page/index] is: -1

　　[org.springframework.web.servlet.DispatcherServlet]-

[DEBUG] Null ModelAndView returned to DispatcherServlet with name ‘springmvc‘: assuming HandlerAdapter completed request handling

　　[org.springframework.web.servlet.DispatcherServlet]-

[DEBUG] Successfully completed request

　　[org.springframework.beans.factory.support.DefaultListableBeanFactory]-

[DEBUG] Returning cached instance of singleton bean ‘sqlSessionFactory‘

结果:

p.p1 { margin: 0.0px 0.0px 0.0px 0.0px; font: 14.0px Monaco; color: #4f76cb }
p.p2 { margin: 0.0px 0.0px 0.0px 0.0px; font: 14.0px Monaco; color: #3933ff }
span.s1 { color: #000000 }
span.s2 { color: #009193 }
span.s3 { color: #4e9192 }
span.s4 { color: #932192 }
span.Apple-tab-span { white-space: pre }

<!-- 配置扫描器，使得@Controller注解生效 -->

<context:component-scan base-package="com.jt.manage.controller" />

但是: 项目中的base-package="controller"!!!

　　base-package名称不一致,导致无法扫描到controller, 才出现以上问题.
