log4j:WARN No appenders could be found for logger in web.xml
java, log4j, spring, spring-mvc
Solution
If that's the entire log4j.properties file it looks like you're never actually creating a logger. You need a line like:
log4j.rootLogger=debug,A1
Problem
I already put the log4jConfigLocation in web.xml, but I still get the following warning: ``` log4j:WARN No appenders could be found for logger ⤦ ⤥ (org.springframework.web.context.ContextLoader). log4j:WARN Please initialize the log4j system properly. ``` What did I miss? ``` <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "java.sun.com/dtd/web-app_2_3.dtd"> <web-app> <context-param> <param-name>contextConfigLocation</param-name> <param-value> /WEB-INF/applicationContext.xml </param-value> </context-param> <context-param> <param-name>log4jConfigLocation</param-name> <param-value>/WEB-INF/classes/log4j.properties</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> <servlet> <servlet-name>suara2</servlet-name> <servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class> </servlet> <servlet-mapping> <servlet-name>suara2</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> </web-app> ```
