java - Log4j logger 只使用 root appender

Question

我的记录器仅在根记录器 ServerAppenderV2 上记录消息，日志文件生成正确，当我使用更改级别以在根中调试时，我可以在根中定义的两个附加器中看到日志，但文件附加器 FileAppender 和 PerfAppender 中仍然没有日志。

对于以下代码：

import logging.Logger;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class TestLog {
  private static final Logger logger= Logger.getLogger(TestLog.class);

    public static void main(String [] args){


       logger.perf("hello from debug",null,null,null,null);
       logger.log(Traces.43E, "info", 12);
       logger.debug("hello from debug",null);
    }
}

这是我的 Logger 类和标记：

public class Logger {

    private static final String ID_TRACE = "IdTrace";
    private static final Marker MARKER_PERF = MarkerFactory.getMarker("perf");
    private static final Marker V2 = MarkerFactory.getMarker("V2");
    private Logger delegate;


    public void debug(String message, Object... objects) {
        delegate.debug(message, objects);
    }

    public void log(Traces trace, Object... params) {

            Marker marker=V2;
            MDC.clear();
            MDC.put(ID_TRACE, trace.getId());

            switch(trace.getLevel()) {
                case DEBUG:
                    this.delegate.debug(marker, trace.getMessage(), params);
                    break;
                case INFO:
                    this.delegate.info(marker, trace.getMessage(), params);
                    break;
                case WARNING:
                    this.delegate.warn(marker, trace.getMessage(), params);
                    break;
                default:
                    this.delegate.error(marker, trace.getMessage(), params);
            }
        }

    public void perf(String msg, Object... params) {
        this.delegate.info(MARKER_PERF, msg, params);
    }

    }

这是我的配置 Log4j2.xml：

    <Properties>
        <Property name="LOG_PATTERN">
            %d{yyyy-MM-dd HH:mm:ss,SSS} %5p --- [%15.15t] %-40.40c{1.} : %m%n%ex

这是因为您将记录器name称为“记录”的配置。

<AsyncLogger name="logging" level="info" additivity="false">
   // configurations
</AsyncLogger>

但是在访问时您正在使用它。

private static final Logger logger= Logger.getLogger(TestLog.class);

package这将使用和解析记录器名称className。

使用您当前的配置，您应该logger像这样访问。

private static final Logger logger= Logger.getLogger("logging");

或者，您可以像这样配置。假设如果你TestLog.class在 package 中org.random.service，你的配置应该是这样的。

<AsyncLogger name="org.random.service.TestLog" level="info" additivity="false">
   // configurations
</AsyncLogger>

要启用完整的包，您可以className从记录器名称中删除。

<AsyncLogger name="org.random.service" level="info" additivity="false">
   // configurations
</AsyncLogger>
