log4j2 Async appender仅适用于调试级别

Question

我有一个Async appender，仅在我设置级别=调试时才有效。对于“错误”级别，它不会记录任何内容。

<Configuration packages="com.custom.appender">
<Appenders>
<CustomLogger name="customLogger"/>
<Async name="customAsync" bufferSize="2" includeLocation="flase">
    <AppenderRef ref="customLogger"/>
</Async>
</Appenders>
<Loggers>
<logger name="com.mypackage" level="error">
    <AppenderRef ref="customAsync"/>
</logger>
</Loggers>
</Configuration>

我不确定这个配置中缺少了什么。这是我正在尝试使用的自定义appender

package com.custom.appender
@Plugin(name = "CustomLogger", category = "Core", elementType = "appender",   printObject = true)
public class CustomLogger extends AbstractAppender {

private static volatile CustomLogger instance;

public CustomLogger(final String name, final Filter filter,
        final Layout<? extends Serializable> layout) {
    super(name, filter, layout);
}

@PluginFactory
public static CustomLogger createAppender(
        @PluginAttribute("name") String name,
        @PluginAttribute("ignoreExceptions") boolean ignoreExceptions,
        @PluginElement("Layout") Layout layout,
        @PluginElement("Filters") Filter filter) {
    if (layout == null) {
        layout = PatternLayout.createDefaultLayout();
    }

    instance = new CustomLogger(name, filter, layout);
    return instance;
}

public static CustomLogger getInstance() {
    return instance;
}

@Override
public void append(LogEvent event) {
    //Log the event to mongoDB
}

}

尝试以下操作

<Configuration packages="com.custom.appender">
    <Appenders>
        <Async name="customAsync" bufferSize="2" includeLocation="flase">
            <AppenderRef ref="customConsoleLogger"/>
        </Async>
        <Console name="customConsoleLogger" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
        </Console>
    </Appenders>

    <Loggers>
        <Logger name="com.mypackage" level="INFO">
            <AppenderRef ref="customAsync"/>
        </Logger>
    </Loggers>
</Configuration>
