1 问题

写kotlin的时候错误提示如下

type checking has run into a recrusive problem. Easiest workaround: specify types of your declarations explicitly

2 分析

我写得是递归函数如下，错误提示就是上面，是因为我们写返回值，才导致

    suspend fun getWhiteUrlList(page: Int = 1, seq: Int = 0, dao: AdWhiteListBeanDao)= withContext(Dispatchers.IO) {
        try {
            if (page == 1) {

            } else {
                getWhiteUrlList(page, seq, dao)
            }
        } catch (e: Exception) {
            false
        }
    }

3 解决办法

这个递归函数加上返回值就行

    suspend fun getWhiteUrlList(page: Int = 1, seq: Int = 0, dao: AdWhiteListBeanDao): Boolean= withContext(Dispatchers.IO) {
        try {
            if (page == 1) {
                true
            } else {
                getWhiteUrlList(page, seq, dao)
            }
        } catch (e: Exception) {
            false
        }
    }
