在web.xml中配置加载spring时，发现项目无法运行；而去掉spring的配置时，项目可以被初始化。
此时应考虑到spring的配置文件中存在错误，以至于web容器无法对项目成功初始化，在web.xml中配置log4j，
根据打印的信息对spring的配置进行修改。
<context-param>
<param-name>log4jConfigLocation</param-name>
<param-value>classpath:log4j.properties</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>

<!-- 加载spring容器 -->

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