EDEN-MACE 是一套灵活的管理佣金的分销管理系统,它涵盖并且总结了目前流行的分销模式,让分销更加简单。

原来的账务的管理,使用策略模式+工厂模式,导致每次新增一个账户之后就会复制大量的重复代码,这样会导致代码大量的冗余。

根据上面的问题,将策略模式换成了模板模式+工厂模式,每次新增一个账户的时候就可以只增加改动的部分即可。

下面演示新增一个交易账户需要做的事(只有最后一段需要新增,第一部分为静态工厂方法初始化,第二部分为模板方法调用,当然省略了部分部分代码,省略的代码为原来的公共代码)

 public AmountTemplateFactoryContext(String type) {
        switch (type){
            case "0":
                amountTemplate = new TradeAmountServiceImpl();
                break;
            case  "1":
                amountTemplate = new LevelAmountServiceImpl();
                break;
            case  "2":
                amountTemplate = new InviteAmountServiceImpl();
                break;
            default:
                break;
        }
    }
