将logback.xml放在我的web应用程序的src / main / resources /文件夹中时，工作正常。
但是，在web.xml中使用LogbackConfigListener（如解释here）来配置logback.xml文件的位置时。日志文件生成成功。
但是，另外在tomcat服务器的控制台上会出现太多的DEBUG日志消息。它延迟了tomcat服务器的启动时间。这些DEBUG消息是第三方库文件的一部分，如Hibernate。
logback.xml文件：
<configuration>
<!-- Appenders -->
<appender name="util" class="ch.qos.logback.core.FileAppender">
<File>${demo.root}/WEB-INF/app.log</File>
<Append>true</Append>
<encoder>
<pattern>%t %-5p %c{2} - %m%n</pattern>
</encoder>
</appender>
<logger name="org.springframework" level="info" />
<root level="info">
<appender-ref ref="util" />
</root>
</configuration>
日志跟踪太大了。我从tomcat服务器的启动窗口中复制了部分内容：

我已经解决了这个问题。
正如here所解释的那样，LogbackConfigListener应该是web.xml文件中的第一个监听器。
我在Spring的ContextLoaderListener下编写了LogbackConfigListener。该序列与Log4jConfigListener一起使用可能是因为两个侦听器都是Spring框架的一部分。
