不可能更改Netbeans日志记录级别

Question

This shouldn't be so complicated... change netbeans default logging level.

Despite the fact that english isn't my primary language, until now, I thought that I had a good understanding of it. Every post that I read states that is simple and easy to change it... But I can't manage to change it. By default, my netbeans starts logging at INFO level. I'm trying to lower it to FINEST.

I did a small POC, starting a brand new java application:

package javaapplication16;

import java.io.IOException;
import java.util.logging.Level;
import java.util.logging.LogManager;
import java.util.logging.Logger;

public class JavaApplication16 {

    private static final Logger logger = Logger.getLogger(JavaApplication16.class.getName());

    public static void main(String[] args) {        
        logger.log(Level.INFO, "hello!");
    }
}

It works fine. "hello!" is printed in netbeans output window. It also works for higher levels (WARNING, SEVERE).

But if I change it to FINE (or any other lower level). It didn't work.

I did everything that that I found on internet.

I changed main to

System.setProperty("javaapplication16.level", "100");
System.setProperty("javaapplication16.JavaApplication16", "100");
System.setProperty("java.util.logging.ConsoleHandler.level", "100");
try {
    LogManager.getLogManager().readConfiguration();
} catch (IOException | SecurityException ex) {
    logger.log(Level.SEVERE, null, ex);
}

logger.log(Level.FINE, "hello!");

Changed netbeans.conf and added -J-Djavaapplication16.level=100 (and others). Created a logging.properties at app root level, etc... Neither alone or combined they worked.

Please, could you help me, point me out what I'm doing wrong?

My environment is:

Product Version: NetBeans IDE 7.2 (Build 201207171143)
Java: 1.7.0_07; Java HotSpot(TM) 64-Bit Server VM 23.3-b01
System: Mac OS X version 10.8.2 running on x86_64; US-ASCII; en_US (nb)

Posts that I found useful, but didn't worked for me:

• Netbeans Logger
• netbeans logging tutorial
• How to logging output in console to file?

Answer 1

I ran into the same problems... My solution (finally) was to create a logging config file:

handlers = java.util.logging.ConsoleHandler
java.util.logging.ConsoleHandler.level = ALL

and set it up to the project running options:

>Project
>Properties
>Run
>VM Options: -Djava.util.logging.config.file=/home/myuser/logging.properties

Note the absolute path to the properties file, since I was not able to not load it from the running classpath (tried default project folder, default packaged, inside a package... and nothing), maybe that was happening when you were trying to load the properties file, given it's difficult some times to correctly determine where is located the current classpath. I based myself on this thread for the solution. Netbeans version 7.2 and JDK jdk1.7.0_21.

Answer 2

 System.setProperty("java.util.logging.ConsoleHandler.level", "FINER");

You need to use the strings representing the levels, rather than their numeric equivalents. That line is copy-pasted from working code using JUL. I've since found that log4j is a far better framework for logging in Java.

The ConsoleHandler has a level also so I allocated a new ConsoleHandler and set both the Logger and ConsoleHandler to the desired level. That worked!

    private static final Logger myLogger=Logger.getLogger(OrderApiClientJersey2_51_1.class.getName());
    static
    {
        // Default consoleHandler and Logger only log at INFO level
        Handler consoleHandler = new ConsoleHandler();  
        consoleHandler.setLevel(Level.ALL);
        myLogger.setLevel(Level.ALL);
        myLogger.addHandler(consoleHandler);
        myLogger.log(Level.FINEST, "Test Output");
    }
