【问题描述】：
我想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。
让我用一个例子更清楚地解释自己。每个 LOC 应放在单独的 LOG 文件中：
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： 发送数据:)
今天收到的内容： 收到的数据:-)
今日行动内容： 行动！！
我进行了一些调查，我正在使用 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。
我通过以下方式创建了关卡：
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);
}
}

有什么提示吗？谢谢你:)
**编辑：**只要目标可行，我就不会在意从 Log4j 1.x 迁移到 2.x（事实上，我已经开始在另一个项目中使用 2.x）。
