線程中沒法自動注入bean

編寫一個獲取上下文全部的bean的工具類

public class SpringContextUtil implements ApplicationContextAware{

    // Spring應用上下文環境
    private static ApplicationContext applicationContext;
    /**
     * 實現ApplicationContextAware接口的回調方法，設置上下文環境
     */
    @Override
    public void setApplicationContext(ApplicationContext applicationContext)
            throws BeansException {
        SpringContextUtil.applicationContext = applicationContext;
    }
    public static ApplicationContext getApplicationContext() {
        return applicationContext;
    }
    /**
     * 獲取對象 這裏重寫了bean方法，起主要做用
     * example: getBean("userService")//注意： 類名首字母必定要小寫！
     */
    public static Object getBean(String beanId) throws BeansException {
        return applicationContext.getBean(beanId);
    }

}

線程類裏面調用

public class ProductThread implements Runnable{

    private final ProductService productService = (ProductService) SpringContextUtil.getBean("productService");

    private final IntegralOrderService integralOrderService = (IntegralOrderService) SpringContextUtil.getBean("integralOrderService");


    private Integer type;
    private Integer productId;
    private Integer userId;

    public ProductThread(Integer type,Integer productId,Integer userId){
        this.type = type;
        this.productId = productId;
        this.userId = userId;
    }
    @Override
    public void run() {
        //添加
        System.out.println("進入線程！");
        if(type==1){
            this.placeAnOrder(productId,userId);
        }       
    }

    public void placeAnOrder(Integer productId,Integer userId){
       *******************
    }

}

這樣就能夠了，可是有一點，若是線程寫成內部類，就不用寫工具類。
