java - 为什么 IntelliJ 在使用本地数据源时找不到数据库用户凭据？

Question

我已添加并可以毫无问题地使用我的生产数据源，但在使用第二个“本地”数据源时遇到问题。我的连接设置如下所示:

数据库 URL:jdbc:mysql://localhost:3306/<database_name>

用户:<username>

密码:<password>

测试连接成功，我可以看到表格列表，但无法读取表格内容。是的，该用户拥有对相关数据库的完全访问权限；我在 MySQL Workbench 中确认了这一点。该问题似乎是 IntelliJ-IDEA 特有的。

IntelliJ-IDEA 如此提示:

java.sql.SQLException: SELECT command denied to user ''@'%' for column 'mycolumn'

通知user是 ''@'%'在错误消息中。出了什么问题？

再次，测试连接成功，我可以看到表列表并且上述用户在 MySQL Workbench 中工作得很好(可以选择/更新/插入所有表)。

我正在运行 IntelliJ-IDEA 版本 12.1.4。

整个连接错误:

database_name.*
java.sql.SQLException: SELECT command denied to user ''@'%' for column 'column_name' in      table 'table_name'

Answer 1

我有一个观点。正如 another post 建议的(信用:@FooBarUser)，我将 View 的“DEFINER”更改为有效的本地用户，问题就解决了!
