@autowired annotation issue, not injecting bean in class, using Spring3.0, hibernate

Question

following is my class:

package com.abc.trade.util;

public class StockTraderLogger {

    static Logger logger = Logger.getLogger("StockTraderLogger");

    @Autowired
    ConfigService configService; 




    public static void debug(Object className, Object logMessage) {     
        try {
            System.out.println("in debug.. ");
            StockTraderLogger stl =new StockTraderLogger();
            stl.addMessage(""+convertToString(className)+"\t"+convertToString(logMessage));
            System.out.println("in debug..post ");
        } catch (DataAccessException e) {
            System.out.println("Caught exception...");
                e.printStackTrace();
        }
    }

    public void addMessage(String message) throws DataAccessException {
        System.out.println("in  add message of util. ");
        System.out.println("String: " + configService); 

        configService.addMessage(message);          
    }
}

@Autowire annotation is not working. It is displaying value of configService as null when called addMessage method. however it is properly injected in some of my Controller classes but not here.

Can anyone explain what is problem? and how to resolve this issue?

Thank you in advance.

ConfigService:

package com.abc.trade.service;
import org.springframework.stereotype.Service;
import com.abc.trade.framework.exception.DataAccessException;

public interface ConfigService {

        public void addMessage(String message) throws DataAccessException;
}

Config Service Implementor:

package com.abc.trade.service;

import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.abc.trade.framework.exception.DataAccessException;
import com.abc.trade.framework.service.CommonServiceImplementor;
import com.abc.trade.model.Log;
import com.abc.trade.model.Mode;
import com.abc.trade.util.StockTraderLogger;

@Service("configService")
public class ConfigServiceImplementor extends CommonServiceImplementor implements ConfigService{

    String errorMessage = "";

    @Override
    public void addMessage(String message) {
        System.out.println("in add message of service...........");
        Log log = new Log();
        try{
            log.setMessage(message);
            System.out.println("Message is: "+message);
            int i=save(log);
        }catch(Exception e)
        {
            errorMessage = "Error in saving debug message";
            e.printStackTrace();
            //throw new DataAccessException(errorMessage);
        }

    }

}

Answer 1

StockTraderLogger is not declared as spring bean and doesn't exist in spring context and for that reason the injection won't work.

<bean id="StockTraderLogger" class="com.abc.trade.util.StockTraderLogger"/>

or

@Component
public class StockTraderLogger { /**/ }
