如何根據消息級別在單獨的文件中記錄消息

Question

我想要做的是創建自定義日誌級別（例如SentLevel，ReceivedLevel和ReadLevel），並將使用它們記錄的消息存儲在單獨的文件中。

讓我通過一個例子更清楚地解釋我自己。每個LOC應該放置在單獨的日誌文件：的

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

內容今天發送： 發送的數據:)的

內容今天收到： 接收數據:-)

內容今天行動： 行動！

我調查了一下，我使用Log4j 1.2.17。我正在使用DailyRollingFileAppender。問題是我記錄的每條消息都存儲在三個文件中。

下列方式我創建等級：

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); 
    } 
}

任何提示？謝謝:)

**編輯：**我不會在意從Log4j 1.x遷移到2.x，只要目標是可行的（事實上，我已經開始在另一個項目中使用2.x ）。

Answer 1

我得到這個小環境中工作的事情：

在Java文件：

1.By定義級別;

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

2.創建記錄器;

Logger test_logger = LogManager.getLogger(); 

3.調用日誌方法將日誌追加到文件中。

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

我log4j2.xml文件是這樣的：

<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> 

的log4j2.xml文件放置在src文件夾中。 還有一件事;我正在使用log4j-api-2.3.jar，log4j-core-2.3.jar

嘗試使用此配置，可能會對您有所幫助。 :)
