org.apache.catalina.core.StandardContext startInternal SEVERE: Error listenerSta

q528

　　今天将项目部署到Centos 6.3 x64上面的tomcat 7.0.54，访问链接出现了404错误。后来查看了/usr/local/apache-tomcat-7.0.54/logs/catalina.out 文件，出现了Error listenerStart 。



org.apache.catalina.core.StandardContext startInternal SEVERE: Error listenerStart

　　再去查看/usr/local/apache-tomcat-7.0.54/logs/localhost.2014-06-13.log 文件，

　　由此日志文件可以知道，在web.xml 初始化logback监听器的的时候找不到classpath:dev/logback.xml。
　　后来去/usr/local/apache-tomcat-7.0.54/webapps/adver/WEB-INF/classes/ 看了，也真的是下面没有dev/logback.xml文件夹。明明在开发的时候，在tomcat里面也是有的。 但是发布的时候，就没有。
　　找到原因：是因为用maven打包的，maven并没有将dev/logback.xml放到WEB-INF/classes里，而是直接将logbak.xml放在WEB-INF/classes。
