完整的錯誤輸出如下：

根據錯消息定位到 JdbcClientDetailsService.java 這個類，查看源碼可以知道查出的數據中有一個空數據轉json報錯

查看數據庫果然 additional_information 字段都是空的。然後在數據庫中先添加了測試字符串，發現還是報同樣的錯誤。

最後百度+google終於在網址找到了下面這篇文章。

根據這篇文章裏的介紹這是一個預留的字段 https://blog.csdn.net/u011676300/article/details/84390988

所以，這個字段我們要麼置爲null,要麼是一個標準格式的json。否則就不填爲null，空字符串或者字符串的null都不行。
