使用log4j2删除滚动文件创建的文件时出现的问题

Question

我已经将log4j2.xml文件配置为删除要删除的超过2分钟(用于测试)的文件。这很好，但我无法删除生成的第一个文件。滚转后，所有文件都将被删除。

我已经附上了一个项目文件夹结构的图片。您可以在日志文件夹中看到2个日志文件。第一个日志文件不会被删除，因为它创建的时间只有3-4毫秒，而且它也不是以指定的格式生成的。

​

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>

    </Properties>

        </Console>
        <RollingFile name="csvFile"

            </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();
         }
     }
 }
 
}

我参考了很多关于堆叠溢出的文章，但都找不出问题。有人能帮我了解第一个文件是如何生成的，以及如何删除它吗？

任何帮助都将不胜感激。谢谢！

我认为这是因为fileName="${baseDir}/csvLog.csv“->是日志输出的当前文件。它超越了删除历史。文件filePattern="${baseDir}/csvLog-%d{yyyy-MM-dd-HH-mm}.csv --是用于滚动(重命名)的文件--“归档日志文件”。每次向日志中写入信息时，都会创建csvLog.csv (如果不存在的话)。我认为第一步是滚动和删除，只有这样才能创建csvLog.csv。
