以下は私のクラスです：
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注釈が機能していません。メソッド呼び出し時の値をnullconfigServiceとして表示しています。ただし、一部の Controller クラスには正しく挿入されていますが、ここには挿入されていません。addMessage
誰が何が問題なのか説明できますか? この問題を解決するにはどうすればよいですか？
