java - DBUnit:NoSuchColumnException ColumnNameToIndexes 缓存映射中的非大写输入列。 map 的列名不区分大小写

Question

我的 java 应用程序将您的信息存储在 MySql 数据库版本 8 中。用户信息和密码存储在该数据库中。我正在实现一个集成测试来测试使用 dbunit 验证数据库中用户的方法。测试方法运行后出现如下错误。

Caused by: org.dbunit.dataset.NoSuchColumnException: USER.USER_ID -  (Non-uppercase input column: USER_ID) in ColumnNameToIndexes cache map. Note that the map's column names are NOT case sensitive.

我通过 MySql Workbench 检查表和列都是大写的，所以显示的错误消息没有意义。有谁知道是什么导致了这个异常？

我找到了问题的解决方案。我只是将以下属性放在 unitils.properties 中，现在一切正常。

org.dbunit.database.IMetadataHandler.implClassName=org.dbunit.ext.mysql.MySqlMetadataHandler
