Logback.xml not logging to ConsoleAppender?
提问by Alterscape
I'm trying to set up a console logger with logback in slf4j. My logback configuration is as follows:
我正在尝试在 slf4j 中设置一个带有 logback 的控制台记录器。我的logback配置如下：
<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<!-- encoders are assigned the type
ch.qos.logback.classic.encoder.PatternLayoutEncoder by default -->
<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<pattern>%-4relative [%thread] %-5level %logger{35} - %msg %n</pattern>
</encoder>
</appender>
<logger name="org.hibernate" level="INFO" />
<logger name="com.myapp" level="TRACE" />
<root level="DEBUG">
<appender-ref ref="STDOUT" />
</root>
</configuration>
Even though Logback seems to set up with no problems, I can't seem to get output from any loggers into my console. I have tested that LOGGER.isInfoEnabled() returns true in my app.
尽管 Logback 似乎设置没有问题，但我似乎无法将任何记录器的输出输入到我的控制台中。我已经测试过 LOGGER.isInfoEnabled() 在我的应用程序中返回 true。
The output of Logback's StatusPrinter:

Any ideas what might be going on here, and how to fix it and get working log output?
任何想法这里可能会发生什么，以及如何修复它并获得工作日志输出？

From the status output, it looks like you are using a version of logback 0.9.18 or earlier. You should try with the latest version.
从状态输出来看，您似乎使用的是 logback 0.9.18 或更早版本。您应该尝试使用最新版本。

For those who need to use logback 0.9.18 due to third party dependencies, see this answer for an example of how to configure the appenders.
