公用代码片码抽取需要不断的强化代码复用意识

抽取前：

    public void handleContext(UniterChineseSelectRequest context) {
    
        IPage<UniterChinese> page = context.buildPage();
        LambdaQueryWrapper<UniterChinese> query= context.buildQuery();
        IPage<UniterChinese> uniterChinesePage = uniterChineseMapper.selectPage(page,query);

        List<UniterChinese> uniterChineses = uniterChinesePage.getRecords();
        List<UniterChineseListVo> uniterChineseVos = list2list(uniterChineses, UniterChineseListVo::new);

        context.setResult(uniterChineseVos);
        context.setTotal(uniterChinesePage.getTotal());
}

抽取后：

    public void handleContext(UniterChineseSelectRequest context) {
    
        IPage<UniterChinese> pageResult = 
        uniterChineseMapper.selectPage(context.buildPage(), context.buildQuery());
        
        context.setPageResult(pageResult,UniterChineseListVo::new);
}

抽取的公用代码片断：

       public <T, E> void setPageResult(IPage<T> pageResult, Function<T, E> fun) {
        List<T> ts = pageResult.getRecords();
        List<E> es = ZYListUtils.list2list(ts, fun);
        this.setResult(es);
        this.setTotal(pageResult.getTotal());
    }

   public static <O, T> List<T> list2list(List<O> os, Function<O, ? extends T> target, boolean needClearRepeat) {
        List<T> ts = new ArrayList<>();
        if (null == os || os.size() == 0) {
            return ts;
        }
        os.forEach(o -> {
            T apply = target.apply(o);
            if (ZYStrUtils.isNotNull(apply)) {
                if (needClearRepeat) {
                    if (!ts.contains(apply)) {
                        ts.add(apply);
                    }
                } else {
                    ts.add(apply);
                }
            }
        });

        return ts;
    }
