Spring Standalone Apps | Logging

Question

I am trying to put log in spring standalone application.Here is my code

import org.apache.log4j.Logger;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.stereotype.Component;


@Component
public class Main {
    static Logger log = Logger.getLogger(Main.class.getName());
    public String id;
    public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }
    public static void main(String[] args) {

       // ApplicationContext context = new ClassPathXmlApplicationContext("spring.xml");
        log.debug("Going to create HelloWord Obj");
        //Main p = (Main) context.getBean("hello");
        //System.out.println(p.getId());
        log.debug("Exiting the program");
        log.debug("Exiting the program1");


    }


}

My log4j.properties is

log4j.rootLogger = DEBUG, FILE

# Define the file appender
log4j.appender.FILE=org.apache.log4j.FileAppender
log4j.appender.FILE.File=C://log.out

# Define the layout for file appender
log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
log4j.appender.FILE.layout.conversionPattern=%m%n

In above code log is working correctly.It is not working when i remove the comment from Main Class. It is throwing some additional info in log.out file which is shown below.Let me know the reason why it is throwing like this..?

The log is still working.. At the bottom you can see

Exiting the program1

there is just additional log from the Spring framework. When the spring container is initialised it will log information of its own, as you see here.

I cant actually see any problem here.

If you want to remove the spring logging you can specify the logging level for a particular package like this in the log4j.properties:

log4j.logger.org.springframework=WARN

Should only show warnings and errors.

I would change your conversionPattern to something like this also: %d{ABSOLUTE} %5p %c{1}:%L - %m%n

This will give alot more information and you will be able to see what package is logging what
