java8 一些函数式伪代码

 public <R> void queryWithPassThrough(String out,String tableName,String time, Class<R> type, BiFunction<String,String,Integer> dbFallback1,
                                         Function<String, Integer> dbFallback, Consumer<List<R>> consumer,
                                         Predicate<Integer> predicate){
        Integer i1 = dbFallback1.apply(tableName,time);
        System.out.println("查询删除条数"+i1);

        List<R> list = JSONUtil.toList(out, type);
        List<List<R>> split = CollUtil.split(list, 1);
        split.forEach(consumer);

        System.out.println("插入完成");

        Integer apply =dbFallback.apply(tableName);

        System.out.println("查询插入后的条数");

        if(predicate.test(apply)){
            System.out.println("判断同步的条数是否等于插入的条数");
        };
    }



    @Test
    void testSimpleFactoryModel1() {
        JSONObject info1 = new JSONObject();
        info1.put("name", "张三");
        info1.put("age", "18");
        JSONObject info2 = new JSONObject();
        info2.put("name", "李四");
        info2.put("age", "19");

        //把上面创建的两个json对象加入到json数组里
        JSONArray array = new JSONArray();
        array.add(info1);
        array.add(info2);

        String jsonStr = JSONUtil.toJsonStr(array);
        System.out.println(jsonStr);

        queryWithPassThrough(jsonStr,"777777","77",
                Map.class,
                (s, s2) -> 777777,
                s -> Integer.valueOf(s),
                maps -> System.out.println(maps),
                integer ->
                ObjectUtil.equals(2,integer)
                );
    }
