log4j:ERROR LogMananger.repositorySelector was null

阅读更多

排除log4j版本问题后,仍出现此问题,解决方法:在Tomcat安装目录下conf/catalina.properties文件中设置org.apache.catalina.loader.WebappClassLoader.ENABLE_CLEAR_REFERENCES=false。

去Tomcat网站上查看了它的含义:

http://tomcat.apache.org/tomcat-6.0-doc/config/systemprops.html

If true , Tomcat attempts to null out any static or final fields from loaded classes when a web application is stopped as a work around for apparent garbage collection bugs and application coding errors.

There have been some issues reported with log4j when this option is true .

Applications without memory leaks using recent JVMs should operate correctly with this option set to false .

If not specified, the default value of true will be used.
