我試圖根據原理log4j2.xml文件在我的應用程序內部飛行中創建新的記錄器配置。該代碼會解釋自己：在飛行中創建新的滾動文件LOG4j2 2.6
XML文件
<?xml version="1.0" encoding="UTF-8"?>
<Configuration monitorInterval="5">
<Appenders>
<Console name="STDOUT" target="SYSTEM_OUT">
<PatternLayout pattern="%-d{yyyy MMM dd HH:mm:ss,SSS} %5p %c{1} - %m%n" />
</Console>
<RollingFile name="file" fileName="./log/application.log"
filePattern="./log/devfix-%-d{yyyy-MM-dd}.log">
<PatternLayout pattern="%-d{yyyy-MM-dd HH:mm:ss.SSS} %5p %c{1} - %m%n" />

</Policies>
<DefaultRolloverStrategy max="10" />
</RollingFile>
<Async name="ASYNC" bufferSize="2048">

<AppenderRef ref="STDOUT" />
</Async>

<RollingFile name="fixfile" fileName="./log/fix.log"

<PatternLayout pattern="%-d{yyyy MMM dd HH:mm:ss,SSS} %c{1} - %m%n" />
<Policies>
<SizeBasedTriggeringPolicy size="50MB" />
</Policies>

</RollingFile>
</Appenders>
<Loggers>
<Logger name="jmsLogger" additivity="false" level="OFF">
<AppenderRef ref="jmsQueue" />
</Logger>
<Logger name="org.hibernate" level="WARN">
</Logger>
<Logger name="FIX_CONFIG" level="INFO" additivity="false">
<AppenderRef ref="fixfile" />
</Logger>
<Root level="info">
<AppenderRef ref="ASYNC" />
</Root>
</Loggers>
</Configuration>
所以在那之後，在代碼中，我使用的方法來創建一個新的rolligFileAppender。
private static Logger getLogger(String platformName) throws IOException {
/*Using a commun configuration to find the new Path for the plaform log file*/
LoggerContext ctx = (LoggerContext) LogManager.getContext(false);
Configuration config = ctx.getConfiguration();
RollingFileAppender fixAppender = (RollingFileAppender) config.getAppender("fixfile");
if(null == fixAppender) {
Logger logger = LogManager.getLogger(platformName);
logger.error("Missing fixfile log4j appender in configuration");
return logger;
}
String fileName = fixAppender.getFileName();
if (null != fileName && fileName.toLowerCase().endsWith(".log"))
try { // remove empty fix.log file created by defaults
new File(fileName).delete();
} catch (Exception e) {
}
/*construction of the new file name depending on the platform*/
int slashIndex = null != fileName ? fileName.lastIndexOf("/") : -1;
fileName = slashIndex >= 0 ? fileName.substring(0, slashIndex + 1) + platformName.toLowerCase() + ".log" : platformName.toLowerCase() + ".log";
/*construction of the new file Pattern depending on the platform*/
String fileNamePattern = fixAppender.getFileName();
int slashIndexPattern = null != fileNamePattern ? fileNamePattern.lastIndexOf("/") : -1;
fileNamePattern = slashIndex >= 0 ? fileNamePattern.substring(0, slashIndexPattern + 1) + platformName.toLowerCase()+"-%-d{yyyy-MM-dd-HH}.log" : platformName.toLowerCase() + "-%-d{yyyy-MM-dd-HH}.log";
ConfigurationBuilder<BuiltConfiguration> builder = ConfigurationBuilderFactory.newConfigurationBuilder();
builder.setStatusLevel(Level.INFO);
builder.setConfigurationName("RollingBuilder");
// create a console appender
AppenderComponentBuilder appenderBuilder = builder.newAppender("Stdout", "CONSOLE").addAttribute("target",
ConsoleAppender.Target.SYSTEM_OUT);
appenderBuilder.add(builder.newLayout("PatternLayout")
.addAttribute("pattern", "%d [%t] %-5level: %msg%n%throwable"));
builder.add(appenderBuilder);
// create a rolling file appender
LayoutComponentBuilder layoutBuilder = builder.newLayout("PatternLayout")
.addAttribute("pattern", " %-d{yyyy-MM-dd HH:mm:ss.SSS} %5p %c{1} - %m%n");
ComponentBuilder triggeringPolicy = builder.newComponent("Policies")
.addComponent(builder.newComponent("TimeBasedTriggeringPolicy"));
appenderBuilder = builder.newAppender("file2", "RollingFile")
.addAttribute("fileName", fileName)
.addAttribute("filePattern", fileNamePattern)
.add(layoutBuilder)
.addComponent(triggeringPolicy);
builder.add(appenderBuilder);
// create the new logger
builder.add(builder.newLogger(platformName.toLowerCase(), Level.INFO)
.add(builder.newAppenderRef("file2"))
.addAttribute("additivity", false));
builder.add(builder.newRootLogger(Level.INFO)
.add(builder.newAppenderRef("file2")));
LoggerContext newctx = Configurator.initialize(builder.build());
return newctx.getLogger(platformName.toLowerCase());
}
問題是我沒有能力創建這個新的記錄器。例如，我用平臺名稱參數=「test」調用這個函數。 ./log/test.log文件已正確創建，但我無法記錄任何內容。我注意到newctx指向我的log4j2.xml文件，所以用他所有的參數進行初始化，例如，當我嘗試去調試時，最後一條語句LoggerContext newctx = Configurator.initialize（builder.build（）並忽略我的指令builer.Build（）。
你知道爲什麼會發生這種情況嗎？
預先感謝您。
