限制log4j2中汇总的日志文件的最大数量

Question

我正在使用log4j2在我的代码中提供日志记录。 我正在使用基于时间的触发器策略。 但是删除工作不适合我，我收到以下错误

016-08-05 14:44:22,635 main ERROR appender RollingFile has no parameter that matches element Delete 
2016-08-05 14:44:22.686 [WARN ] [main] Class1 - new cycle 
2016-08-05 14:44:22.691 [DEBUG] [main] Class1 - Hello this is a debug message 
2016-08-05 14:44:22.691 [INFO ] [main] Class1 - Hello this is an info message 
2016-08-05 14:44:22.692 [FATAL] [main] Class1 - Beaware This is a Fatal message 
2016-08-05 14:44:22.692 [ERROR] [main] Class1 - This is an error message 
2016-08-05 14:44:22.692 [INFO ] [main] Class2 - In constructor of class2 
2016-08-05 14:44:22.692 [INFO ] [main] Class1 - Repeating cycle 
2016-08-05 14:44:22.692 [DEBUG] [main] Class1 - Hello this is a debug message 
2016-08-05 14:44:22.692 [INFO ] [main] Class1 - Hello this is an info message

2016-08-05 14:44:22.693 [ERROR] [main] Class1 - This is an error message 

下面是我的log4j2配置文件

<?xml version="1.0" encoding="UTF-8"?> 
<Configuration status="warn"> 
    <Properties> 
     <Property name="log-path">D:/logs</Property> 
    </Properties>

     </Console> 
     <RollingFile name="file-log" fileName="${log-path}/custom-log.log" 
      filePattern="${log-path}/customelog-%d{yyyy-MM-dd HH-mm}.log">

       <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%-5level] [%t] %c{1} - %msg%n 
       </pattern> 
      </PatternLayout> 
      <Policies> 
       <TimeBasedTriggeringPolicy interval="1" modulate="true" /> 
      </Policies> 
      <Delete basePath="${log-path}" maxDepth="2"> 
       <IfFileName glob="customelog-*.log" /> 
       <IfLastModified age="1m" /> 
      </Delete> 
     </RollingFile> 
    </Appenders> 
    <Loggers> 
     <Logger name="test.Class1" level="debug" additivity="false"> 
      <appender-ref ref="file-log" level="debug" /> 
      <appender-ref ref="console-log" level="debug" /> 
     </Logger> 
     <Root level="all" additivity="false"> 
      <AppenderRef ref="console-log" /> 
     </Root> 
    </Loggers> 
</Configuration> 

我的测试代码如下

class1.java：

package test; 

import org.apache.logging.log4j.LogManager; 
import org.apache.logging.log4j.Logger; 

public class Class1 { 
    public static Logger logger = LogManager.getLogger(Class1.class); 

    public static void main(String[] args){ 
     logger.warn("new cycle"); 
     logger.debug("Hello this is a debug message"); 
     logger.info("Hello this is an info message"); 
     logger.fatal("Beaware This is a Fatal message"); 
     logger.error("This is an error message"); 

     Class2 obj = new Class2(); 

     logger.info("Repeating cycle"); 
     logger.debug("Hello this is a debug message"); 
     logger.info("Hello this is an info message"); 
     logger.fatal("Beaware This is a Fatal message"); 
     logger.error("This is an error message"); 
    } 
} 

Class2.java

package test; 

import org.apache.logging.log4j.LogManager; 
import org.apache.logging.log4j.Logger; 

public class Class2 { 
    public static Logger logger = LogManager.getLogger(Class2.class); 
    public Class2(){ 
     Class2.logger.info("In constructor of class2"); 
    } 

} 

的问题是上述错误，事实上，这些文件没有被清除，如果有年龄超过1分钟

能否请你让我知道我是因为它的制作有什么错我的删除功能不起作用？

我用下面以下为例Log4j2 - Configure RolloverStrategy to delete old log files

它看起来像你的Delete标记应在DefaultRolloverStrategy

例如包裹

<RollingFile name="RollingFile" fileName="D:/app.log" 
        filePattern="D:/app-%d{yyyy-MM-dd-HH-mm-ss}.log"> 
      <PatternLayout> 
       <Pattern>%d %p %c{1.} [%t] %m%n</Pattern> 
      </PatternLayout> 
      <Policies> 
       <TimeBasedTriggeringPolicy interval="60" modulate="true"/> 
       <!--<SizeBasedTriggeringPolicy size="250 MB"/>--> 
      </Policies> 
      <DefaultRolloverStrategy> 
       <Delete basePath="D:" maxDepth="1"> 
        <IfFileName glob="app-*.log" /> 
        <IfLastModified age="3m" /> 
       </Delete> 
      </DefaultRolloverStrategy> 
     </RollingFile>
