原因

没有提供者导致运行失败

产生原因

少配置一个关键性位置,导致启动失败

找到当前service的web.xml文件

出错配置:

<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath*:spring/applicationContext-service.xml</param-value>
</context-param>

改正配置:

<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath*:spring/applicationContext-*.xml</param-value>
</context-param>

总结

• 因为视频中少配置文件所以导致和自己的结果不一样
• 视频中是eclipse, 而我用的是idea
