Question

是我的第一个问题，抱歉，如果我在提问时提出错误。

这是我对log4j2的疑问。（我使用spring framework java）

我的目标是在FILE中写入在具有Logger实例的类中生成的所有日志。

为此，我有以下log4j.properties文件：

name=PropertiesConfig
property.filename = C:/sts-bundle/Tomcat 7.0/logs
appenders = console,rolling

appender.console.type = Console
appender.console.name = STDOUT
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = [%-5level] %d{dd MMM yyyy HH:mm:ss,SSS} [%t] %c{5} - %msg%n

appender.rolling.type = RollingFile
appender.rolling.name = RollingFile
appender.rolling.fileName = ${filename}/fnelLog-${date:dd-MM-yyyy}.log
appender.rolling.filePattern = ${filename}/fnelLog-%d{dd-MM-yyyy}-%i.log
appender.rolling.layout.type = PatternLayout
appender.rolling.layout.pattern = [%-5level] %d{dd MMM yyyy HH:mm:ss,SSS} [%t] %c{5} - %msg%n
appender.rolling.policies.type = Policies
#appender.rolling.policies.time.type = TimeBasedTriggeringPolicy
#appender.rolling.policies.time.interval = 2
#appender.rolling.policies.time.modulate = true
appender.rolling.policies.size.type = SizeBasedTriggeringPolicy
appender.rolling.policies.size.size=50MB
appender.rolling.strategy.type = DefaultRolloverStrategy
appender.rolling.strategy.max = 4

loggers = rolling

 ############ HERE IS MY PROBLEM, I Only reference to this class, but I want to    add another, 
 ############ so I can write all logs in a file described in lines before
logger.rolling.name = fnel.bcp.org.main.TestMain
logger.rolling.level = debug
#logger.rolling.additivity = false
logger.rolling.appenderRefs = rolling
logger.rolling.appenderRef.rolling.ref = RollingFile


rootLogger.level = debug
rootLogger.appenderRefs = stdout
rootLogger.appenderRef.stdout.ref = STDOUT

现在这里是我使用Logger界面的两个部分。

public class FooClass {

    private static Logger logger = LogManager.getLogger(FooClass.class);

    public void testLog4j() {
        // TODO Auto-generated method stub
        logger.debug("This is a debug message");
        logger.info("This is an info message");
        logger.warn("This is a warn message");
        logger.error("This is an error message");
        logger.fatal("This is a fatal message");
    }

}



public class TestMain {

  private static Logger logger = LogManager.getLogger(TestMain.class);

  public static void main(String[] args) {
    FooClass foo = new FooClass();

    //Calling foo method
    foo.testLog4j();

    // TODO Auto-generated method stub
    logger.debug("This is a debug message");
    logger.info("This is an info message");
    logger.warn("This is a warn message");
    logger.error("This is an error message");
    logger.fatal("This is a fatal message");
  }

}

这些是控制台中的输出

所以，我的问题是如何在log4j.properties文件中添加FooClass。因为我在TestMain类旁边添加了这样的“fnel.bcp.org.main.TestMain，fnel.bcp.org.main.FooClass”，但是没有用。

我尝试在不同的logger.rolling.name中分隔，但也没有用。

Answer 1

更改行

logger.rolling.name = fnel.bcp.org.main.TestMain

到

logger.rolling.name = fnel.bcp.org.main

这将导致fnel.bcp.org.main包中的任何类被定向到RollingFile appender。或者，如果您想要文件中的所有内容，您只需删除记录器定义并将根记录器更改为指向RollingFile而不是STDOUT。

Log4j 2：如何在我的log4j.properties
