使用jdbc-provider在Mule中配置Spring Security

Question

我有以下Mule App，我正在尝试使用数据库来提供用户（jdbc-provider）的Spring Security保护它。

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出现以下错误：

无法获得JDBC连接。 嵌套异常为java.sql.SQLException：找不到适用于jdbc：mysql：// localhost：3306 / test的驱动程序（org.springframework.jdbc.CannotGetJdbcConnectionException）org.springframework.jdbc.datasource.DataSourceUtils：80（空）

Mule App（基于Mule ESB 3.6.1）：

Answer 1

这是a子的问题。 将罐子添加到

<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不为各个数据库连接提供jdbc驱动程序。 我们需要将jar显式添加到项目开发的类路径中。
