Question

我有以下Mule应用程序，我试图通过Spring Security使用数据库来保护用户（jdbc-provider）。

我在Mule App的类路径中正确配置了mysql数据库和mysql jdbc驱动程序，但是当我尝试登录时，我收到以下错误：

无法获取JDBC连接;嵌套异常是java.sql.SQLException：没有为jdbc找到合适的驱动程序：mysql：// localhost：3306 / test（org.springframework.jdbc.CannotGetJdbcConnectionException） org.springframework.jdbc.datasource.DataSourceUtils：80（null）

Answer 1

这是一个骡子问题。将jar添加到

<MULE_PATH>/mule-standalone-3.x.0/lib/mule

和

<MULE_STUDIO_PATH>/AnypointStudio/plugins/org.mule.tooling.server.3.x.xxxx/mule/lib/mule

Answer 2

默认情况下，mole不为各自的DB连接提供jdbc驱动程序。我们需要明确地将jar添加到项目开发的类路径中。

使用jdbc-provider在Mule中配置Spring Security
