如何根据消息的级别将消息记录在单独的文件中 [英] How to log messages in separate files depending on their level

问题描述

我要做的是创建自定义日志级别(例如SentLevel，ReceivedLevel和ReadLevel)，并将使用它们记录的消息存储在单独的文件中.

What I want to do is create custom log Levels (for example SentLevel, ReceivedLevel and ReadLevel) and store the messages logged using them in separate files.

让我用一个例子更清楚地说明自己.每个LOC都应放在单独的LOG文件中:

Let me explain myself more clearly, with an example. Each LOC should be placed in separate LOG files:

    logger.log(ResultadosEnviadosLevel.RESULTADOS_ENVIADOS, "sent data :)");
    logger.log(ResultadosRecibidosLevel.RESULTADOS_RECIBIDOS, "received data :-)");
    logger.log(CustomLevel.ACCION, "action!!");

今天发送的内容: 发送的数据:)

Content of today-sent: sent data :)

今天收到的内容: 接收到的数据:-)

Content of today-received: received data :-)

今天行动的内容: 行动！！

Content of today-action: action!!

我进行了一些调查，然后使用Log4j 1.2.17.我正在使用DailyRollingFileAppender.问题是我记录的每条消息都存储在三个文件中.

I've investigated a bit and I'm using Log4j 1.2.17. I'm using DailyRollingFileAppender. The issue is that every message I log it's stored within the three files.

我已经通过以下方式创建了关卡:

I've created Levels in the following way:

import org.apache.log4j.Level;

public class CustomLog4jLevel extends Level {

    private static final long serialVersionUID = 6031879473353817158L;

    /**
     * Value of AccionLog4jLevel level. This value is lesser than DEBUG_INT and higher
     * than TRACE_INT}
     */
    public static final int ACCION_INT = DEBUG_INT - 10;

    /**
     * Level representing my log level
     */
    public static final Level ACCION = new CustomLog4jLevel(ACCION_INT, "ACCION", 10);

    /**
     * Constructor
     */
    protected CustomLog4jLevel(int arg0, String arg1, int arg2) {
        super(arg0, arg1, arg2);

    }

    /**
     * Checks whether logArgument is "Accion" level. If yes then returns
     * Accion}, else calls AccionLog4jLevel#toLevel(String, Level) passing
     * it Level#DEBUG as the defaultLevel.
     */
    public static Level toLevel(String logArgument) {
        if (logArgument != null && logArgument.toUpperCase().equals("ACCION")) {
            return ACCION;
        }
        return (Level) toLevel(logArgument);
    }

    /**
     * Checks whether val is AccionLog4jLevel#Accion_INT. If yes then
     * returns AccionLog4jLevel#Accion, else calls
     * AccionLog4jLevel#toLevel(int, Level) passing it Level#DEBUG as the
     * defaultLevel
     * 
     */
    public static Level toLevel(int val) {
        if (val == ACCION_INT) {
            return ACCION;
        }
        return (Level) toLevel(val, Level.DEBUG);
    }

    /**
     * Checks whether val is AccionLog4jLevel#Accion_INT. If yes
     * then returns AccionLog4jLevel#Accion, else calls Level#toLevel(int, org.apache.log4j.Level)
     * 
     */
    public static Level toLevel(int val, Level defaultLevel) {
        if (val == ACCION_INT) {
            return ACCION;
        }
        return Level.toLevel(val, defaultLevel);
    }

    /**
     * Checks whether logArgument is "Accion" level. If yes then returns
     * AccionLog4jLevel#Accion, else calls
     * Level#toLevel(java.lang.String, org.apache.log4j.Level)
     * 
     */
    public static Level toLevel(String logArgument, Level defaultLevel) {
        if (logArgument != null && logArgument.toUpperCase().equals("ACCION")) {
            return ACCION;
        }
        return Level.toLevel(logArgument, defaultLevel);
    }
}

有任何提示吗?谢谢:)

Any hint? Thank you :)

****只要目标可行，我就不会从Log4j 1.x迁移到2.x(实际上，我已经在另一个项目中开始使用2.x).

** ** I wouldn't care migrating from Log4j 1.x to 2.x as long as the goal is feasible (indeed, I've started using 2.x in another project).

推荐答案

通过这种小的设置，我可以使事情正常进行:

I am getting the things working by this small settings:

在JAVA文件中:

1.通过定义级别；

1.By defining the Level;

Level TEST = Level.forName("TEST", 250);

2.创建记录器；

Logger test_logger = LogManager.getLogger();

3.调用log方法将日志附加到文件中.

3.Calling log method to append the logs in file.

test_logger.log(TEST, "test log message");

我的log4j2.xml文件是这样的:

My log4j2.xml file is like this:

<Configuration status="WARN">

<CustomLevels>
    <CustomLevel name="TEST" intLevel="150" />
</CustomLevels>

<Appenders>
    <File name="TestFile" fileName="/var/tmp/logs/test.log">
        <PatternLayout pattern="%d %-7level %logger{36} - %msg%n" />
    </File>
</Appenders>

<Loggers>
    <Root level="WARN">
        <AppenderRef ref="TestFile" level="test" />
    </Root>
</Loggers>

</Configuration>

log4j2.xml文件位于src文件夹中. 还有一件事;我正在使用log4j-api-2.3.jar，log4j-core-2.3.jar

The log4j2.xml file is placed in the src folder. One more thing; I am using log4j-api-2.3.jar, log4j-core-2.3.jar

尝试使用此配置，可能对您有帮助. :)

Try using this configuration, may be it help you. :)
