使用 Spring MVC 为多个数据源配置 MyBatis

Question

我一直在尝试使用 Spring MVC 配置 MyBatis 以使用多个数据库。我有一个页面试图连接到其中一个数据库以获取数据，以便可以将其填充到下拉框中。

现在我不确定这个配置有什么问题，但我收到以下错误：

]] Root cause of ServletException. org.springframework.jdbc.BadSqlGrammarException: ### Error querying database.  Cause: java.sql.SQLException: ORA-06576: not a valid function or procedure name

我这里提供XML文件供大家参考

Answer 1

根据异常：BadSqlGrammarException: ### Error querying database. Cause: java.sql.SQLException: ORA-06576: not a valid function or procedure name，命中了一个DB

阅读错误 ORA-06576。

问题可能与程序的调用方式有关。正确的方法是 { CALL MyProcedure (#arg0, #arg1) }

配置显示相同的映射器可以用于两个数据源，如果目标模式不同会发生什么？
