WARN No appenders could be found for logger (org.springframework.web.context.ContextLoader).

错误现象：

每次启动Tomcat6.0总会出现如下提示，但不影响Tomcat正常运行。提示如下：

log4j:WARN No appenders could be found for logger (org.springframework.web.context.ContextLoader).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

问题原因：

之前是通过设置Servlet自启动来初始化Log4j的配置，因此可能与后面采用的Spring不兼容。

原配置如下：

	<servlet>
		<description>启动并初始化Log4j，启动定时扫描任务</description>
		<servlet-name>InitServlet</servlet-name>
		<servlet-class>servlet.InitServlet</servlet-class>
		<init-param>
			<param-name>log4jConfigFile</param-name>
			<param-value>WEB-INF/log4j.properties</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>/WEB-INF/applicationContext*.xml</param-value>
	</context-param>

	<listener>
		<listener-class>
			org.springframework.web.util.Log4jConfigListener
		</listener-class>
	</listener>

	<listener>
		<listener-class>
			org.springframework.web.context.ContextLoaderListener
		</listener-class>
	</listener>

解决方法：

使用org.springframework.web.util.Log4jConfigListener配置代替自定义的InitServlet来初始化Log4j，即删除InitServlet配置

	<context-param>
		<param-name>log4jConfigLocation</param-name>
		<param-value>/WEB-INF/log4j.properties</param-value>
	</context-param>

	<listener>
		<listener-class>
			org.springframework.web.util.Log4jConfigListener
		</listener-class>
	</listener>

注意：要严格按照以上配置顺序。
