这是我web.xml的内容

Answer 1

能不能说详细点哦。我把web.xml贴出来了

Answer 2

 Duplicate context initialization parameter contextConfigLocation
 在web.xml 中配置了两个 <context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/classes/spring/*.xml</param-value>
</context-param>
  删掉一个就OK了

Answer 3

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/classes/spring/*.xml</param-value>
</context-param><context-param>
<param-name>log4jConfigLocation</param-name>
<param-value>/WEB-INF/classes/log4j.properties</param-value>
</context-param>
这两个写重复了，特意试试了，是这样的。
