<context:component-scan>
Web.xml中
<servlet>
<servlet-name>springMVC</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>
如下配置
<context:component-scan base-package="com.xt.web.controller" />
<context:component-scan base-package="com.xt" /> //暂时有错
springMVC.xml中需要能扫描到Controller.
否则出现:
org.springframework.web.servlet.PageNotFound noHandlerFound
警告: No mapping found for HTTP request with URI [/traffic/w] in DispatcherServlet with name ‘springMVC‘。
1.Web.xml中
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-hibernate.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
spring-hibernate.xml文件中配置serivce,dao等spring要素。
<context:component-scan base-package="com.xt.domain" />
//路径需要到dao,service等javabean的目录的上级目录.
