我正在尝试从中运行示例springboot应用程序 https://www.codetreat.com/spring-boot-data-jpa-hibernate-with-ms-sql-server-rest-crud-example/
我已将我的应用程序与sqlserver连接。在运行该应用程序时，出现以下错误：
org.springframework.beans.factory.UnsatisfiedDependencyException：创建名称为“ org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration”的bean时出错：通过构造函数参数0表示的不满意依赖关系；嵌套异常是org.springframework.beans.factory.BeanCreationException：创建在类路径资源[org / springframework / boot / autoconfigure / jdbc / DataSourceConfiguration $ Tomcat.class]中定义的名称为“ dataSource”的bean时出错：通过工厂方法实例化Bean失败;嵌套的异常是org.springframework.beans.BeanInstantiationException：无法实例化[org.apache.tomcat.jdbc.pool.DataSource]：工厂方法'dataSource'引发了异常；嵌套的异常是java.lang.IllegalStateException：无法加载驱动程序类：com.microsoft.sqlserver.jdbc.SQLServerDriver
我尝试了有关该错误的所有可能的解决方案，但均未能成功。

答案 0 :(得分：0)
您必须在类路径中添加sqlserver驱动程序依赖项，而无需添加此行
<scope>runtime</scope>
更新：
使用此代码
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>sqljdbc4</artifactId>
<version>4.0</version>
</dependency>
更新2 在application.properties中，您应该使用此行
spring.datasource.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver
