删除使用 log4j2 滚动文件创建的文件时出现的问题

Question

我已经配置了log4j2.xml文件，以删除2分钟以上（用于测试）的文件。这可以正常工作，但我无法删除生成的第一个文件。翻转后，所有文件都将被删除。

我附上了项目文件夹结构的图像。您可以在日志文件夹中看到2个日志文件。由于创建的时间仅为3-4毫秒左右，也没有以指定格式生成，因此第一个日志文件没有被删除。

这是我的log4j2.xml文件：

    <?xml version="1.0" encoding="UTF-8"?>
<Configuration status="trace">
    <Properties>
        <Property name="csvLog.fileName">csvLog</Property>
        <Property name="file-header">sender,flow,message</Property>
        <Property name="baseDir">logs</Property>
    </Properties>
    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout
                pattern="%d{yyyy-MM-dd} %-5p %c{1}:%L - %m%n" />
        </Console>
        <RollingFile name="csvFile" 
                     fileName="${baseDir}/csvLog.csv"
                     filePattern="${baseDir}/csvLog-%d{yyyy-MM-dd-HH-mm}.csv">
            <CsvParameterLayout delimiter="," header="${file-header}\n"/>
            <Policies>
                <TimeBasedTriggeringPolicy interval="1" modulate="true" />
             <!--   <SizeBasedTriggeringPolicy size="1 KB" /> -->
            </Policies>
            <DefaultRolloverStrategy>
               <Delete basePath="${baseDir}" maxDepth="1">
                  <IfFileName glob="csvLog*.csv" /> 
                  <IfLastModified age="2m" />
                </Delete>
            </DefaultRolloverStrategy>
        </RollingFile>
    </Appenders>
    <Loggers>
        <Logger name="CSVLOG" level="debug" additivity="false">
            <appender-ref ref="csvFile" level="debug"/>
        </Logger>
        <Root level="debug" additivity="false">
            <AppenderRef ref="Console" level="debug"/>
        </Root>
    </Loggers>
</Configuration>

这是我的主要文件：

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class })
public class App {
 private static final Logger csvlogger = LogManager.getLogger("CSVLOG");
 private static final Logger logger = LogManager.getLogger();

 public static void main(String args[]){

     SpringApplication.run(App.class);
     
     csvlogger.info("Debug Message", "Namaste", "Whats up", "hmm..ok");
     logger.info("You have made an error");
     logger.debug("Debug Message");
     
     runMe("test");
 }
 
 private static void runMe(String parameterParam){
     String parameter;
     for(int i=0; i<100; ++i) {
         parameter = parameterParam + i;
         System.out.println("log iteration: "+i);
         if (csvlogger.isDebugEnabled()) {
             csvlogger.debug(new ObjectArrayMessage("JD", "Ri", parameter));
         }

         if (csvlogger.isInfoEnabled()) {
             csvlogger.info(new ObjectArrayMessage("JD", "Ri", parameter));
         }

         csvlogger.info(new ObjectArrayMessage("JD", "Ri", parameter));
         csvlogger.info(new ObjectArrayMessage("JD", "Ri", parameter));
         csvlogger.info(new ObjectArrayMessage("JD", "Ri", parameter));
         try {
             Thread.sleep(60000);
         } catch (InterruptedException e) {
             e.printStackTrace();
         }
     }
 }
 
}

我已经转介了很多关于Stackoverflow的文章，但无法弄清楚这个问题。谁能帮助我了解第一个文件的生成以及如何删除？

任何帮助将不胜感激。谢谢 ！

我认为这是因为filename =“ $ {laseir}/csvlog.csv” - ＆gt;是日志输出的当前文件。它是碧昂删除的历史。和文件fiLepattern =“ $ {lasedir}/csvlog-％d {yyyy-mm-dd-hh-mm} .csv-是用于滚动的文件（重命名） - “存档日志文件”。每次将信息写入日志中CSVLOG.CSV将被创建（如果不是EXSITS），我想第一步是滚动和删除，然后将创建CSVLOG.CSV。 org/log4j/2.x/手动/附录器.html＃rollingFileAppender“ rel =” nofollow noreferrer“> https://logging.apache.org/log4j/2.x/manual/manual/appenders.html #html #html #html＃rollingfilingfileappender
