1. 利用BeanComparator对List<Object>根据属性进行排序

        String daXiaoOrder[] = {"很小","小","中","大"，"特大"};

        String tianDuOrder[] = {"不甜","甜","很甜"}

        ComparatorChain comparatorChain = new ComparatorChain();

        FixedOrderComparator fixedOrderComparator1 = new FixedOrderComparator(daXiaoOrder);

        FixedOrderComparator fixedOrderComparator2 = new FixedOrderComparator(tianDuOrder);

         //daXiao 和 tianDu 是Apple类的成员变量

        comparatorChain.addComparator(new BeanComparator("daXiao",fixedOrderComparator1));

        comparatorChain.addComparator(new BeanComparator("tianDu",fixedOrderComparator2));

        Collections.sort(appleList, comparatorChain);
