解決:TooManyResultsException: Expected one result (or null) to be returned by selectOne(), but found:
通過分析錯誤可知:需要的查詢出一條數據,但是結果卻大相徑庭,出現的是多條結果(只要不是一條結果就是多條結果),從而應發了TooManyResultsException 錯誤。 錯誤截圖: 由出現的事故來看,很有可能是 Sql 語句或者數據庫方面的問題,從這個地方開始着手,分析我們的問題: 先看一下 resultType 是不是我們對應的數據類型: 你我的問題出現的方式可能不是一樣的,所以先檢查看看
