无法加载 JDBC 驱动程序 class - Spring 批处理独立程序
Could not load JDBC driver class - Spring Batch standalone program
我正在开发一个 Spring 批处理程序，运行将它作为一个 command-line 应用程序（目前通过 STS 进行测试）。当我通过 org.springframework.batch.core.launch.support.CommandLineJobRunner 通过 Eclipse run/debug 配置 运行 它时，它无法加载 SQL 服务器 JDBC 驱动程序。我确定我在 class 路径上有它，但显然它仍然有问题。
这是控制台日志中的异常跟踪：

我的数据源配置来自 spring xml（为了保护无辜者，细节已更改）：
<bean id="legacyDatasource" class="org.springframework.jdbc.datasource.SingleConnectionDataSource">
<property name="driverClassName" value="com.microsoft.jdbc.sqlserver.SQLServerDriver" />
<property name="url" value="jdbc:microsoft:sqlserver://server:1433;DatabaseName=database" />
<property name="username" value="user" />
<property name="password" value="pw" />
</bean>
现在 classpath 东西...安装在我的本地 maven 仓库中：
在我的 pom 中：
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>sqljdbc41</artifactId>
<version>4.1</version>
</dependency>
它在我项目的 Maven 依赖项中：
在我的 运行 配置中，我尝试将它直接添加到 class 路径选项卡上的 class 路径，并通过 VM 参数。
我很确定这很简单。为什么无法加载驱动程序的任何想法？对我来说，还值得注意的是它不是 class 未找到错误（尽管它可能在幕后而不是此堆栈跟踪的一部分）。
包名中有jdbc&sqlserver调换。
