Log4j property file is ingored

For some reason, my log4j configuration file is getting ignored.
The configuration is file found in
C:\dev\pa-backup-restore-utility\BackupRestore\log4j2.properties
Here are the contents of the file:
name=PropertiesConfig
property.filename = logs
appenders = console, file
appender.console.type = Console
appender.console.name = STDOUT
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = [%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n
appender.file.type = File
appender.file.name = LOGFILE
appender.file.fileName=logs/backupRestore.log
appender.file.layout.type=PatternLayout
appender.file.layout.pattern=[%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n
loggers=file
logger.file.name=log4j2.properties
logger.file.level = error
logger.file.appenderRefs = file
logger.file.appenderRef.file.ref = LOGFILE
rootLogger.level = error
rootLogger.appenderRefs=stdout,logfile
rootLogger.appenderRef.stdout.ref=STDOUT
rootLogger.appenderRef.logfile.ref=LOGFILE
The batch file that runs the class is located in the same directory as the configuration file.
The command from the batch file is run as follows:
set javaPath="%appDir%\jre\bin\java.exe"
%javaPath% -Dapp.properties.path=windows.app.properties -Dlog4j.configurationFile=file:log4j2.properties -jar backupRestore-jar-with-dependencies.jar -b
The entry in pom.xml for this is:
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-to-slf4j</artifactId>
<version>2.16.0</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
<version>1.7.36</version>
</dependency>
Here's how a logger.info is called:
static void printWarning(String message) {
logger.info("============== warning ===============================");
logger.info("== " + message);
logger.info("============== warning ===============================");
}
However, when I run the batch job, an info message gets displayed in the console:
[main] INFO com.sick.backup.util.Utils - ============== warning ===============================
[main] INFO com.sick.backup.util.Utils - == here is an example message
[main] INFO com.sick.backup.util.Utils - ============== warning ===============================
Also, a log file is no longer getting generated.
This was all working at what point. I'm trying to track down the version to make sure it matches, but the only change I've made is to upgrade the version of log4j-to-slf4j due to prevent a vulnerability.

Log4j does literally nothing?

My configuration file is path of the class path. At least I thought it is. I placed the log4j.properties file in the resources folder and log4j does nothing with it. Even if I delete it, no error occurs.
As anyone can see I'm using maven
Content of LoggerTest:
package com.dersimi.stella.logger;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
public class LoggerTest {
public static void main(String[] args) {
System.out.println("xxx");
Logger logger = LogManager.getLogger(LoggerTest.class);
logger.info("Hello this is an info message");
System.out.println("xxx");
}
}
Program output:
xxx
xxx
Content of log4j.properties:
log4j.rootLogger=INFO, console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.Threshold=INFO
log4j.appender.console.Target=System.out
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.conversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} %-5p - %m%n
In pom.xml is nothing out of the ordinary, just the dependency org.apache.logging.log4j log4j-core 2.17.2, compiler source target is 16, no plugins

The main problem is that you are trying to use log4j (the first one) configurations for log4j2.
In first place make sure you have the following dependencies:
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-core</artifactId>
<version>2.17.0</version>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-api</artifactId>
<version>2.17.0</version>
</dependency>
Second, have a file named log4j2.properties with a content like this:
status = warn
appender.console.type = Console
appender.console.name = LogToConsole
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = [%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n
rootLogger.level = info
rootLogger.appenderRef.stdout.ref = LogToConsole

spring boot .war tomcat application logs not there

I am trying to write to my webapp logs to a .log file in the /logs directory in tomcat but the file is not generated nor is any logging output going to the console other than the spring logs and tomcat logs. When I run spring boot as a jar file with the embedded tomcat it writes to the log file just fine, but as soon as I deploy to tomcat via the webapps folder the application logs are no where to be found.
SpringBoot 2.1.2
Java 1.8
Tomcat 8.5
I have tried:
configuring LOGGING_CONFIG in setenv.sh
Multiple loggers.. logback, java utils etc..
application.properties:
logging.file=../logs/my-app.log
logging.level.org.springframework=INFO
logging.level.com.bose=DEBUG
log4j.properties for log4j:
log4j.rootLogger=${marge.log.level}, stdout, file
# Direct log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=marge.log
#when stdout is also specified it will not write to the file
log4j.appender.file.MaxFileSize=1MB
# Keep one backup file
log4j.appender.file.MaxBackupIndex=1
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{dd MMM yyyy HH:mm:ss,SSS} [%c] [%-5p] %n%m%n
# Direct log messages to stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
# stdout uses PatternLayout
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{HH:mm:ss,SSS} [%c] [%-5p] %n%m%n
# Print only messages of level DEBUG or above in the package com.bose
log4j.logger.com.app=${log.level}
Expected: when I deploy my webapp in /webapps the application logs (generated by log4j) should be in my-app.log in the /logs directory
Actual: No file is generated and no logs are even in stdout/console

By default spring boot uses logback as a logging binder, so the key concept here to exclude logback first then include log4j
Example:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-logging</artifactId>
</exclusion>
</exclusions>
</dependency>
After that add log4j 2 dependency:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-log4j2</artifactId>
</dependency>
Add your log4j2.properties file to src/main/resources to be on classpath
Finally pay attention to what logging interface you are using this is important, with the above configuration you should use apache logging like:
package com.example;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.ApplicationContext;
#SpringBootApplication
public class Application extends SpringBootServletInitializer {
private static final Logger LOGGER = LogManager.getLogger(Application.class);
public static void main(String[] args){
ApplicationContext ctx = SpringApplication.run(Application.class, args);
LOGGER.info("Info level log message");
LOGGER.debug("Debug level log message");
LOGGER.error("Error level log message");
}
}

Getting issue in log4j API logs generation

I am facing issue in generating logs on console.
Below is the snippents I am trying with :-
pom.xml:-
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>
</dependency>
log4j.properties file :-I have kept this in src/main/resources folder
#Set level
log4j.rootCategory=debug, console, file
# Appender which writes to console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%d{MM-dd-yyyy HH:mm:ss} %F %-5p [%t] %c{2} %L - %m%n
# Appender which writes to a file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=D:\eclipse-workspace\CucumberWithTestNGForSelenium\application.log
# Defining maximum size of a log file
log4j.appender.file.MaxFileSize=10mb
log4j.appender.file.MaxBackupIndex=10
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{ISO8601} %5p [%t] %c{1}:%L - %m%n
log4j.appender.file.Append=true
And,below is my Test File
package stepDefinition;
import org.apache.log4j.Logger;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.annotations.Test;
public class GenerateLogs {
final static Logger log=Logger.getLogger(GenerateLogs.class);
#Test
public void Test1()
{
System.setProperty("webdriver.chrome.driver", "C:\\Users\\Mkap\\Downloads\\chromedriver.exe");
WebDriver driver=new ChromeDriver();
log.info("Launching chrome browser");
driver.get("http://google.com");
}
#Test
public void Test2()
{
System.out.println("Yeh!google has opened");
}
}
Can you please help why logs are not getting generated on console. Also,why am not able to resolve errors of Logger class.

Try with root logger instead of rootCategory
log4j.rootLogger=DEBUG,console,file
Find documentation here http://logging.apache.org/log4j/1.2/manual.html

log4j does not create a log file in the system

I am creating a Spring Boot Application in STS (Spring Tool Suite).
The problem occurs when trying to log using log4j. It does not create the log file in the system, though it does log on the console. I tried various methods given in the forum(including checking case-sensitivity, , but I think I am going wrong somewhere. An elaborate response would be really helpful.
I have a dependency in the pom.xml file for the log4j jar:-
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>
</dependency>
In my log4j.properties file, I am trying to have logs in console as well as a file
# Root logger option
log4j.rootLogger=ALL, stdout, file
# Redirect log messages to console
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.conversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
# Redirect log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=C:\\log4j.log
log4j.appender.file.ImmediateFlush=true
log4j.appender.file.MaxFileSize=5MB
log4j.appender.file.MaxBackupIndex=10
log4j.appender.file.layout=org.apache.log4j.PatternLayout
#log4j.appender.FILE.layout.conversionPattern=%m%n
log4j.appender.file.layout.conversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
Java controller where I want to log (IndexController.java)
package com.project.Controller;
import org.apache.log4j.Logger;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
#Controller
public class IndexController {
final static Logger logger = Logger.getLogger(IndexController.class.getName());
#RequestMapping("/")
String index(Model model) {
logger.info("in index");
return "index";
}
}
Please comment if you need any further details. Thanks

Create a dependency for spring-boot-starter-log4j and exclude spring-boot-starter-logging in your pom.xml.Make the following entry in your pom.xml:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-logging</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-log4j</artifactId>
</dependency>
This should create the log file and log the details.
