原因
沒有提供者導致執行失敗
產生原因
少配置一個關鍵性位置,導致啟動失敗
找到當前service的web.xml檔案
出錯配置:
<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>
總結
- 因為視訊中少配置檔案所以導致和自己的結果不一樣
- 視訊中是eclipse, 而我用的是idea
