[SpringMVC]ClassNotFoundException: org.springframework.web.context.ContextLoaderListener

ClassNotFoundException: org.springframework.web.context.ContextLoaderListener

1.有可能是web.xml下的配置不正确. 检查确认无误

2.第二种可能:包没有导入到tomcat下.

我导入后可以发布成功. 但是仔细看发布信息

有这样一段信息:

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.

解决方案: 1.网上有一种说法是:把ContextLoaderListener改为SpringContextServlet.其实可以试试.

                   2.下面主要说一下第二种方案.

在web.xml中加入:

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

<!-- 定义LOG4J监听器 -->
<listener>
<listener-class>
org.springframework.web.util.Log4jConfigListener
</listener-class>
</listener>

log4j.properties代码如下:

# Set root logger level to error
log4j.rootLogger=INFO, Console, File

###### Console appender definition #######

# All outputs currently set to be a ConsoleAppender.
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.layout=org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=%d{ABSOLUTE} %-5p [%c{3}] %m%n
#log4j.appender.Console.layout.ConversionPattern=%d{ABSOLUTE} %-5p [%c] %m%n

###### File appender definition #######
log4j.appender.File=org.apache.log4j.DailyRollingFileAppender
log4j.appender.File.File=spring.log
log4j.appender.File.Append=false
log4j.appender.File.layout=org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern=%d{ABSOLUTE} %-5p [%c] %m%n

具体是什么原因我也不知道. ╮(╯▽╰)╭
