通过类名直接获取某个spring对象

@SuppressWarnings("unchecked")public static <T> T getBean(String name) {return (T) ContextLoader.getCurrentWebApplicationContext().getBean(name);}

public static TradeService getDao(){
if(tradeService==null){
tradeService = SpringUtil.getBean("tradeService");
}
return tradeService;
}
