当我将我的 war 文件部署my-server.war到 Tomcat7（使用mvn cargo:deployor mvn cargo:redeploy）时，我得到了错误Error listenerStart和Context [/my-server] startup failed due to previous errors（见下面的日志片段）。

Jul 12, 2013 12:52:41 PM org.apache.catalina.startup.HostConfig deployWAR

为了诊断此错误，我想配置 Tomcat 日志记录，以便在日志文件中显示堆栈跟踪。

我更改了log4j.propertiesandlogging.properties如下所示，但我仍然看不到堆栈跟踪。

我应该更改哪个日志记录配置文件的哪个部分，以便在日志文件中显示两个错误 (Error listenerStart和Context [/my-server] startup failed due to previous errors) 的详细信息？

log4j.properties：

log4j.rootLogger=debug, R 
log4j.appender.R=org.apache.log4j.RollingFileAppender 
log4j.appender.R.File=${catalina.home}/logs/tomcat.log 
log4j.appender.R.MaxFileSize=10MB 
log4j.appender.R.MaxBackupIndex=10 
log4j.appender.R.layout=org.apache.log4j.PatternLayout 
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n 
log4j.logger.org.apache.catalina=DEBUG, R
log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost]=DEBUG, R
log4j.logger.org.apache.catalina.core=DEBUG, R
log4j.logger.org.apache.catalina.session=DEBUG, R

我发现这种奇怪的行为是由下面标记的行引起的。

<bean id="SomeService" class="com.mycompany.SomeService">
    <property name="persistence" ref="persistence" /> <!-- This line causes the deployment problems -->
</bean>

在确定 和 的值name不同ref后，我可以成功部署我的 WAR 文件。
