Question

我在 IDE IntelliJ 上使用 spring boot 创建了这个 java 应用程序 以下是我的配置文件。应用程序构建成功，但出现此错误：

解决了这个问题，
将 jar 添加到类路径但没有用

我已经浏览了许多网络上可用的解决方案，但没有一个对我有用

在 Zakir 的建议之后，我更新了我的驱动程序依赖项，但仍然出现以下错误： 抱歉，已经试过了

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'inMemoryDatabaseShutdownExecutor' defined in class path resource [org/springframework/boot/devtools/autoconfigure/DevToolsDataSourceAutoConfiguration.class]: Unsatisfied dependency expressed through method 'inMemoryDatabaseShutdownExecutor' parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.zaxxer.hikari.HikariDataSource]: Factory method 'dataSource' threw exception; nested exception is java.lang.IllegalStateException: Cannot load driver class: com.microsoft.sqlserver.jdbc.SQLServerDriver

使用更新后的 jar 并更改 gradle 依赖项，如下所示：

testCompile group: 'com.microsoft.sqlserver', name: 'mssql-jdbc', version: '6.1.0.jre7'
