Log4J中DailyRollingFileAppender的Javadoc表明基于时间的滚动只发生在基于单位的滚动（日、周、月等）上。这意味着您可以获得的最接近该模式的模式是'.'yyyy-MM-dd-HH-mm，它将每分钟滚动一次。
我的建议是执行以下操作之一：

• 由于您是以固定的时间间隔运行的，因此编写一个自定义的FileAppender，它使用从DailyRollingFileAppender借用的逻辑来进行计算
• 如果您有一定的灵活性，可以从Log4J切换到LOGBack，并编写一个自定义的RollingPolicy，它使用从LOGBack时间计算中借用的逻辑（这将与Log4J中的逻辑非常相似）

顺便说一下，如果您选择后者，我建议您考虑编写SLF4J API，并使用LOGBack（或Log4J）作为底层实现。

我创建了这个附加器。它是DailyRollingFileAppender的副本，只是做了一些修改。首先我删除了类型HALF_DAY（这里它没有任何意义），并添加了一个变量timeInterval。现在，每隔x就将此日志记录到文件中。某些内容取决于datePatter。例如：
此日志每2分钟

log4j.appender.APP=path.to.class.CustomRollingFileAppender
log4j.appender.APP.DatePattern=.yyyy-MM-dd-HH-mm
log4j.appender.APP.TimeInterval=2

此日志每3小时

log4j.appender.APP=path.to.class.CustomRollingFileAppender
log4j.appender.APP.DatePattern=.yyyy-MM-dd-HH
log4j.appender.APP.TimeInterval=3

/**
 * DailyRollingFileAppender extends {@link FileAppender} so that the underlying file is rolled over at a user chosen
 * frequency.
 * 
 * <p>
 * The rolling schedule is specified by the <b>DatePattern</b> option. This pattern should follow the
 * {@link SimpleDateFormat} conventions. In particular, you <em>must</em> escape literal text within a pair of single
 * quotes. A formatted version of the date pattern is used as the suffix for the rolled file name.
 * 
 * <p>
 * For example, if the <b>File</b> option is set to <code>/foo/bar.log</code> and the <b>DatePattern</b> set to
 * <code>'.'yyyy-MM-dd</code>, on 2001-02-16 at midnight, the logging file <code>/foo/bar.log</code> will be copied to
 * <code>/foo/bar.log.2001-02-16</code> and logging for 2001-02-17 will continue in <code>/foo/bar.log</code> until it
 * rolls over the next day.
 * 
 * <p>
 * Is is possible to specify monthly, weekly, half-daily, daily, hourly, or minutely rollover schedules.
 * 
 * <p>
 * <table border="1" cellpadding="2">
 * <tr>
 * <th>DatePattern</th>

 * Logging for the month of June will be output to <code>/foo/bar.log</code> until it is also rolled over the next
 * month.
 * 
 * <tr>
 * <td><code>'.'yyyy-ww</code>

下面是我的附加器XML片段：

<appender name="PRIMARY_APPENDER" class="com.stackoverflow.log4j.DistinctDailyFileAppender">
  <param name="Threshold" value="DEBUG"/>
  <param name="Directory" value="X:\\apps\\logs\\cheese\\"/>
  <param name="Append" value="true"/>
  <param name="Hourly" value="true"/>
  <param name="Prefix" value="appname_log."/>
  <param name="Suffix" value=".txt"/>

  <layout class="org.apache.log4j.PatternLayout">
    <param name="ConversionPattern" value="%d{HH:mm:ss,SSS} %-5p [%.3t] %-14.14c{1} %m%n"/>
  </layout>
</appender>

我知道它的答复晚了，但下面的解决方案将帮助您和其他用户谁搜索相同的问题，并坚持回到这个线程。
我修改了DailyRollingFileAppender.java以在文件滚动中包含时间间隔子句，这将允许用户设置必须完成滚动的分钟间隔
包括此处文件http://abheygupta.com/DailyRollingFileAppender.java
并且以这种方式配置，时间间隔可以具有60个因子中的任何值[1，2，3，4，5，6，10，12，15，20，30，60] log4j.appender.mtlog_api11.DatePattern ='.'mmHHMMddyyyy log4j.appender.mtlog_api11.TimeInterval=10
它将在除上面指定DatePattern之外的其他DatePattern中正常工作。

通过logback，您可以创建RollingFileAppender的子类。

public class FifteenMinuteAppender<E> extends RollingFileAppender<E>
{
   private static long start = System.currentTimeMillis(); // minutes
   private int rollOverTimeInMinutes = 15;

   @Override
   public void rollover()
   {
      long currentTime = System.currentTimeMillis();
      int maxIntervalSinceLastLoggingInMillis = rollOverTimeInMinutes * 60 * 1000;

      if ((currentTime - start) >= maxIntervalSinceLastLoggingInMillis)
      {
         super.rollover();
         start = System.currentTimeMillis();
      }
   }
}

然后使用该追加器作为具有滚动策略的追加器

<appender class="com.your.package.FifteenMinuteAppender" name="YOUR_APPENDER">
  <file>yourfile.csv</file>
  <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
    <!-- daily rollover -->
    <fileNamePattern>yourfile-%d{yyyyMMdd-HHmm}.csv</fileNamePattern>
  </rollingPolicy>
  <encoder>
    <pattern>%d{YYYYMMDD-HHmmSS-ZZ};${HOSTNAME};%thread;%msg%n</pattern>
  </encoder>
</appender>
