Question

我正在使用log4j2来配置我的代码中的日志记录。我正在使用基于时间的触发器策略。但是删除对我不起作用，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 [FATAL] [main] Class1 - Beaware This is a Fatal message
2016-08-05 14:44:22.693 [ERROR] [main] Class1 - This is an error message

以下是我的log4j2配置文件

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

        <RollingFile name="file-log" fileName="${log-path}/custom-log.log"

            </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>

我的测试代码在

之下

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");
    }

}

问题是上面提到的错误以及如果年龄超过1分钟文件没有被删除的事实

您能否告诉我我正在制作的错误，因为我的删除功能无效？

我在Log4j2 - Configure RolloverStrategy to delete old log files

使用了以下示例

谢谢，

您的Delete标记应该包含在DefaultRolloverStrategy

中

e.g。

<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>

限制log4j2中最大卷起的日志文件数
