@autowired annotation Problem, nicht injizierenden bean in der Klasse, mit Spring3.0, hibernate

folgende ist meine Klasse:

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 nicht funktioniert. Es zeigt den Wert configService als null, wenn Sie aufgerufen addMessage Methode. aber es ist richtig injiziert, die in einigen meiner Klassen Controller, aber nicht hier.

Kann mir jemand erklären was ist das problem? und wie dieses Problem zu beheben?

Vielen Dank im Voraus.

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-Implementierung:

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);
        }

    }

}
