Question

这是我的log4j.properties

# Define the root logger with appender file
log4j.rootLogger = DEBUG,FILE

# Define the file appender
log4j.appender.FILE=org.apache.log4j.FileAppender
log4j.appender.FILE.File=/media/.I have given the whole path../MyProject/log.log

# Define the layout for file appender
log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
log4j.appender.FILE.layout.conversionPattern=%d{MM-dd@HH:mm:ss} %-5p (%13F:%L) %3x - %m%n

这是我的java文件

package examples;

import java.util.logging.Logger;

import org.apache.log4j.PropertyConfigurator;

public class Test {

    static Logger logger = Logger.getLogger(Test.class.getName());

    public static void main(String a[]){

        //PropertiesConfigurator is used to configure logger from properties file
        PropertyConfigurator.configure("log4j.properties");

        //Log in console in and log file
        //logger.debug("Log4j appender configuration is successful !!");
        logger.info("Log4j appender configuration is successful !!");

    }   

}

我仍然在控制台上获取输出消息，只有我的log.log文件为空。我有权限写入该文件我在日食中运行这是一个问题。

使用log4j包中的Logger。

import org.apache.log4j.LogManager;
import org.apache.log4j.Logger;

像这样创建你的记录器：

static final Logger logger = LogManager.getLogger(Test.class.getName());

log4j没有捕获java.util.logging日志消息。

log4j没有写入文件
