Logback TimeBasedRollingPolicy当前文件名无日历

Question

我正在以编程方式使用TimeBasedRollingPolicy配置Logback RollingFileAppender。它看起来像这样：

    RollingFileAppender<ILoggingEvent> rollingAppender = new RollingFileAppender<ILoggingEvent>();
    TimeBasedRollingPolicy<ILoggingEvent> policy = new TimeBasedRollingPolicy<ILoggingEvent>();
    policy.setContext(rootLogger.getLoggerContext());
    policy.setFileNamePattern(filePath + "/log.%d.txt");
    policy.setMaxHistory(90);
    policy.setParent(rollingAppender);
    policy.start();

    rollingAppender.setContext(context);
    rollingAppender.setRollingPolicy(policy);
    rollingAppender.setTriggeringPolicy(policy);
    rollingAppender.setLayout(layout.getLayout());
    rollingAppender.start();
    rootLogger.addAppender(rollingAppender);

理想情况下，今天的日志将在log.txt中，之前滚动的日志将在log。％d.txt中。实际上，即使今天的日志也在log。％d.txt中。如何获取当天日志的单独日志文件名？

使用rollingAppender.setFile("foo.txt");。活动文件名是appender的属性，而不是策略。
