Log4j2-LogManager。getLogger（“名称”）未找到自定义记录器

Question

Log4j2-LogManager。getLogger（“名称”）未找到自定义记录器。

以下所有操作都返回相同的记录器，即此代码所在类的根记录器。我想这些都会有所不同，我会在前3个电话中拿回我的3个定制电话。注意：将创建appender指定的文件，但不会向其发送日志。

Logger _l = (Logger) LogManager.getLogger("Global");
       _l = (Logger) LogManager.getLogger("fakeswitch");
       _l = (Logger) LogManager.getLogger("fakeswitch_two");
       _l = (Logger) LogManager.getLogger();

我使用以下方法创建自定义记录器：

ComponentBuilder triggeringPolicy = configurationBuilder.newComponent("Policies")
        .addComponent(configurationBuilder.newComponent("TimeBasedTriggeringPolicy").
                addAttribute("interval", "1"));

AppenderComponentBuilder log4jFileAppenderBuilder = configurationBuilder.
        newAppender(pName + "_SmdrDailyRollingFileAppender", "RollingFile");
log4jFileAppenderBuilder.addAttribute("filename", pLogFilename);
log4jFileAppenderBuilder.addAttribute("filePattern", pLogFilenamePattern);
log4jFileAppenderBuilder.addComponent(triggeringPolicy);

// Configure the PatternLayout
LayoutComponentBuilder layoutComponentBuilder = configurationBuilder.newLayout("PatternLayout").
        addAttribute("pattern", DEBUG_PATTERN_LAYOUT_STRING);
log4jFileAppenderBuilder.add(layoutComponentBuilder);

// Add it back into configuration
configurationBuilder.add(log4jFileAppenderBuilder);

// https://logging.apache.org/log4j/2.x/manual/customconfig.html
LoggerComponentBuilder logger = configurationBuilder.newLogger(pName, Level.DEBUG);
logger.add(configurationBuilder.newAppenderRef(pName + "_SmdrDailyRollingFileAppender"));
logger.addAttribute("additivity", false);
configurationBuilder.add(logger);

// Actually use it
LoggerContext _loggerContext = Configurator.initialize(configurationBuilder.build());

writeXmlConfiguration中的等效XML为：

<?xml version="1.0" ?>
<Configuration>
    <Appenders>
        <RollingFile name="Global_SmdrDailyRollingFileAppender" filename="ps/debug/SMDR_DEBUG.txt"
                     filePattern="ps/debug/SMDR_DEBUG_%d{yyyyMMdd}.txt.gz">
            <Policies>
                <TimeBasedTriggeringPolicy interval="1"/>
            </Policies>
            <PatternLayout pattern="%d{MM.DD.yy-HH:mm:ss} %m%n"/>
        </RollingFile>
        <RollingFile name="fakeswitch_SmdrDailyRollingFileAppender" filename="ps/debug/SMDR_DEBUG_fakeswitch.txt"
                     filePattern="ps/debug/SMDR_DEBUG_fakeswitch_%d{yyyyMMdd}.txt.gz">
            <Policies>
                <TimeBasedTriggeringPolicy interval="1"/>
            </Policies>
            <PatternLayout pattern="%d{MM.DD.yy-HH:mm:ss} %m%n"/>
        </RollingFile>
        <RollingFile name="fakeswitch_two_SmdrDailyRollingFileAppender"
                     filename="ps/debug/SMDR_DEBUG_fakeswitch_two.txt"
                     filePattern="ps/debug/SMDR_DEBUG_fakeswitch_two_%d{yyyyMMdd}.txt.gz">
            <Policies>
                <TimeBasedTriggeringPolicy interval="1"/>
            </Policies>
            <PatternLayout pattern="%d{MM.DD.yy-HH:mm:ss} %m%n"/>
        </RollingFile>
    </Appenders>
    <Loggers>
        <Logger name="Global" level="DEBUG" additivity="false">
            <AppenderRef ref="Global_SmdrDailyRollingFileAppender"/>
        </Logger>
        <Logger name="fakeswitch" level="DEBUG" additivity="false">
            <AppenderRef ref="fakeswitch_SmdrDailyRollingFileAppender"/>
        </Logger>
        <Logger name="fakeswitch_two" level="DEBUG" additivity="false">
            <AppenderRef ref="fakeswitch_two_SmdrDailyRollingFileAppender"/>
        </Logger>
    </Loggers>
</Configuration>

Answer 1

彼得卡瓦兹为我回答了这个问题。

只有当LoggerContext尚未初始化时，这才有效。由于每次调用LogManager方法都会初始化LoggerContext，因此使用Configurator几乎肯定为时已晚。初始化。

使用配置。改为重新配置，这在所有情况下都有效。

---我的代码更改是

LoggerContext _loggerContext = Configurator.initialize(configurationBuilder.build());

到

Configurator.reconfigure(configurationBuilder.build());
