【问题描述】：
我想用 Apache Tomcat v7.0.54 创建两个数据源。以下代码代表两个数据源配置
<Context>
<Resource name="jdbc/TestDB" auth="Container" type="javax.sql.DataSource"
maxActive="100" maxIdle="30" maxWait="10000"
username="javauser" password="javadude" driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/javatest"/>
<Resource name="jdbc/TestDB1" auth="Container" type="javax.sql.DataSource"
maxActive="100" maxIdle="30" maxWait="10000"
username="javauser1" password="javadude1" driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost1:3306/javatest1"/>
</Context>
现在我想添加第二个数据源，它是不同的 mysql 服务器。实际上我添加了第二个，当我启动 tomcat 时连接成功。但是当我尝试执行任何查询时，我得到了以下错误
java.lang.UnsupportedOperationException：不支持 基本数据源
我该如何解决这个问题？我也使用 Spring 框架。

您可以执行任何查询。
【问题讨论】：
-
请显示整个配置、执行查询的代码和完整的异常堆栈跟踪。
-
@MarkRotteveel 我更新了我的问题，请检查一下。
-
尝试改变这一行的id：
。即第二个可能是 -
@user6904265 这是我的错误，我复制粘贴并忘记更改。在我的配置中它们是不同的
-
你也用hibernate？你能在这个案例中发布 hybernate 配置吗？
