無法加載JDBC驅動程序類 - Spring批處理獨立程序

Question

我正在開發Spring Batch程序，將其作爲命令行應用程序運行（目前通過STS進行測試）。當我通過org.springframework.batch.core.launch.support.CommandLineJobRunner通過Eclipse運行/調試配置運行它時，它無法加載SQL Server JDBC驅動程序。我確定我在類路徑上有它，但顯然它仍然存在問題。

下面是從控制檯登錄我的異常跟蹤：

從Spring的XML我的數據源配置（詳細信息已更改，以保護無辜的課程）：

<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> 

現在到classpath東西...安裝在我本地的maven回購：

在我的POM：

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

而且它在我的項目的Maven依賴：

在我跑的配置，我試過直接將它添加到類路徑Classpath選項卡上，並通過虛擬機參數。

我敢肯定，這是簡單的東西。任何想法爲什麼驅動程序無法加載？對我來說還值得注意的是，它不是一個沒有找到類的錯誤（雖然它可能在封面而不是這個堆棧跟蹤的一部分）。

Answer 1

如果jdbc & sqlserver轉換爲包名稱。

<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>
