我知道我们以前有过这个问题，但这是不同的。
我正在构建一个基于Spring的Web应用程序
现在我在插入希伯来语时得到一个问号
所以我调试了应用程序，我发现请求是可以的
所以我探索了一下，我发现我需要使我的数据库UTF-8完全没有帮助，我仍然得到？????
现在奇怪的是，当我将JDBC驱动程序从
jdbc:mysql://host:3306/DatabaseName
到
jdbc:mysql://host:3306/DatabaseName?useUnicode=yes&characterEncoding=UTF-8
我开始感到异常

可能是你的问题
description varchar(255) CHARACTER SET latin1
在你的桌子上。尝试使用
description varchar(255) CHARACTER SET utf8
它会解决问题的。
