Custome log in spring 5.1 onwords

Add a new class to your package myLoggerConfig.java
------------------------------------------------------------------------------

package com.mgt.springdemo;

import java.util.logging.ConsoleHandler;
import java.util.logging.Level;
import java.util.logging.Logger;
import java.util.logging.SimpleFormatter;

import org.springframework.context.annotation.AnnotationConfigApplicationContext;

public class MyLoggerConfig {

private String rootLoggerLevel;
private String printedLoggerLevel;

public void setRootLoggerLevel(String rootLoggerLevel) {
this.rootLoggerLevel = rootLoggerLevel;
}

public void setPrintedLoggerLevel(String printedLoggerLevel) {
this.printedLoggerLevel = printedLoggerLevel;
}

public void initLogger() {

// parse levels
Level rootLevel = Level.parse(rootLoggerLevel);
Level printedLevel = Level.parse(printedLoggerLevel);

// get logger for app context
Logger applicationContextLogger = Logger.getLogger(AnnotationConfigApplicationContext.class.getName());

// get parent logger
Logger loggerParent = applicationContextLogger.getParent();

// set root logging level
loggerParent.setLevel(rootLevel);

// set up console handler
ConsoleHandler consoleHandler = new ConsoleHandler();
consoleHandler.setLevel(printedLevel);
consoleHandler.setFormatter(new SimpleFormatter());

// add handler to the logger
loggerParent.addHandler(consoleHandler);
}

}




then add the following to your applicationContext.xml
-------------------------------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>

    <!-- Define your beans here -->
 
   
     <bean id="myLoggerConfig" class="com.luv2code.springdemo.MyLoggerConfig" init-method="initLogger">

    </bean>
   
       <bean id="myBook"
        class="com.mgt.springdemo.TrackBook">
