Question

我已按照此链接mvn install安装了我的sqljdbc4.jar。它完全成功完成并且我的库中加载了sqljdbc4.jar也是我的spring bean，我在部署时得到的依赖和错误。任何人都可以帮助我，我失踪的地方。怎么办？

我的Spring bean是：

<bean id="dataSource"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource">

        <property name="driverClassName" value="com.microsoft.sqlserver.jdbc.SQLServerDriver" />
        <property name="url" value="jdbc:sqlserver://vinodh-pc:1433" />
        <property name="username" value="sa" />
        <property name="password" value="vinodh" />
    </bean>

我的依赖是：

<dependency>
    <groupId>com.microsoft.sqlserver</groupId>
    <artifactId>sqljdbc4</artifactId>
    <version>${sql.jdbc.version}</version>
    <scope>runtime</scope>
</dependency>

当我正在部署以下错误时：

Answer 1

我不是没有确切的原因，为什么它与cmd和eclipse的行为不同，但我通过运行cmd中的mvn命令然后通过eclipse IDE进行了尝试。然后它工作正常

Answer 2

我最近遇到此错误。当我将spring-boot-starter-parent版本更改为更新版本时，此问题已解决。

因此，只要您确定依赖关系，但仍然遇到错误，建议您也检查依赖关系的版本。

无法在Maven项目中加载JDBC驱动程序类[com.microsoft.sqlserver.jdbc.SQLServerDriver]
