我正在写一个小的java项目，打算把网球运动员的数据插入到数据库中。但是，我得到了这个错误：

2023-02-25T15:52:06.800-05:00 ERROR 16196 --- [           main] com.zaxxer.hikari.HikariConfig           : Failed to load driver class org.h2.Driver from HikariConfig class classloader jdk.internal.loader.ClassLoaders$AppClassLoader@4d7e1886

这会导致以下错误：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'dataSourceScriptDatabaseInitializer' defined in class path resource [org/springframework/boot/autoconfigure/sql/init/DataSourceInitializationConfiguration.class]: Unsatisfied dependency expressed through method 'dataSourceScriptDatabaseInitializer' parameter 0: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class]: Failed to instantiate [com.zaxxer.hikari.HikariDataSource]: Factory method 'dataSource' threw exception with message: Failed to load driver class org.h2.Driver in either of HikariConfig class loader or Thread context classloader

有人知道我在项目中做错了什么吗？我的pom.xml：

1）我尝试向pom.xml添加不同的依赖项，以确定这是否是一个问题，但没有帮助。

如错误所示，看起来您在pom.xml中缺少了H2依赖项

<dependency>
    <groupId>com.h2database</groupId>
    <artifactId>h2</artifactId>
    <scope>runtime</scope>
</dependency>
