无法加载JDBC驱动程序类 - Spring批处理独立程序

Question

我正在开发Spring Batch程序，将其作为命令行应用程序运行（目前通过STS进行测试）。当我通过org.springframework.batch.core.launch.support.CommandLineJobRunner通过Eclipse运行/调试配置运行它时，它无法加载SQL Server JDBC驱动程序。我确定我在类路径上有它，但显然它仍然存在问题。

下面是从控制台登录我的异常跟踪：

从Spring的XML我的数据源配置（详细信息已更改，以保护无辜的课程）：

<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> 

现在到classpath东西...安装在我本地的maven回购：

在我的POM：

<dependency> 
    <groupId>com.microsoft.sqlserver</groupId> 
    <artifactId>sqljdbc41</artifactId> 
    <version>4.1</version> 
</dependency> 

而且它在我的项目的Maven依赖：

在我跑的配置，我试过直接将它添加到类路径Classpath选项卡上，并通过虚拟机参数。

我敢肯定，这是简单的东西。任何想法为什么驱动程序无法加载？对我来说还值得注意的是，它不是一个没有找到类的错误（虽然它可能在封面而不是这个堆栈跟踪的一部分）。

Answer 1

如果jdbc & sqlserver转换为包名称。

<bean id="legacyDatasource" class="org.springframework.jdbc.datasource.SingleConnectionDataSource"> 
    <property name="driverClassName" value="com.microsoft.sqlserver.jdbc.SQLServerDriver" /> 
    <property name="url" value="jdbc:sqlserver://server:1433;DatabaseName=database" /> 
    <property name="username" value="user" /> 
    <property name="password" value="pw" /> 
</bean>
