我无法获得子日志级别来覆盖父日志级别。我在Spring Boot应用程序中具有以下logback配置。
<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true" scanPeriod="5 seconds" debug="true">
<appender name="Console" class="ch.qos.logback.core.ConsoleAppender">
<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<pattern>%p %C{1.} [%t] %m%n</pattern>
</encoder>
</appender>
<!-- LOG everything at DEBUG level -->
<root level="DEBUG">
<appender-ref ref="Console" />
</root>
<Logger name="org.springframework" level="INFO" />
<Logger name="org.springframework.web.servlet.handler" level="DEBUG" />
</configuration>
我希望已经显示了来自org.springframework.web.servlet.handler的所有调试日志。覆盖父级的INFO级别。但是，我看不到来自org.springframework.web.servlet.handler的任何调试日志。
我故意没有在请求中传递必需的标头参数来获取400状态代码。不会显示org.springframework.web.servlet.handler.AbstractHandlerExceptionResolver类中缺少标题的日志。
但是，如果我将org.springframework的日志级别设置为DEBUG，则它可以工作。但我不想这样做，因为它会从其他程序包中引入很多日志，从而在日志文件中产生噪音。
子记录器是否应覆盖父记录器的日志级别？
