Autowired注解的妙用---在Controller里的构造函数里获取需要注入的对象

/*@Resource
private Observer<TaxiObserverVo> taxiPushObserver;


@Resource
private Observer<TaxiObserverVo> taxiFlowObserver;



public Pay () {
super();
addObserver(taxiFlowObserver);
addObserver(taxiPushObserver);
}*/

 

@Autowired
public Pay (Observer<TaxiObserverVo> taxiPushObserver,Observer<TaxiObserverVo> taxiFlowObserver) {
addObserver(taxiFlowObserver);
addObserver(taxiPushObserver);
}

当时这么写 是为了 改变加载顺序

PS：Java变量的初始化顺序为：静态变量或静态语句块–>实例变量或初始化语句块–>构造方法–>@Autowired
