java - 如何获取logback.xml中appender中设置的文件路径

Question

我想在 logback.xml 的appender中设置文件路径(以及文件名) 我需要使用哪个类。请帮忙。以下是我的附加程序

<appender name="SIFT" class="ch.qos.logback.classic.sift.SiftingAppender">
    <discriminator class="com.hotwaxmedia.logger.ThreadNameBasedDiscriminator"/>
    <sift>
        <appender class="ch.qos.logback.core.FileAppender">
            <file>runtime/logs/app-${threadName}.html</file>
            <layout class="ch.qos.logback.classic.PatternLayout">
                <pattern>%p %d ${threadName} [%logger{0} : %-5level] %msg%n%rEx</pattern>
            </layout>
        </appender>
    </sift>
</appender>

Answer 1

您可以通过编程方式加载附加程序

LoggerContext context = (LoggerContext)LoggerFactory.getILoggerFactory();
for (Logger logger : context.getLoggerList()) {
  for (Iterator<Appender<ILoggingEvent>> index = logger.iteratorForAppenders();     index.hasNext();) {
     Appender<ILoggingEvent> appender = index.next();
  }
}

然后您可以验证 appender 是否是 FileAppender 并调用 getFile()。看看文档 http://logback.qos.ch/apidocs/ch/qos/logback/core/FileAppender.html
