问题：

无法加载driver class name MongoDB . JDBC . mongodriver的类

有人能帮我吗？我已经在这里呆了两天了。我在spring boot上工作，可以访问两个数据源。应用程序使用HikariCp连接到Postgresql和mongodb，但我得到了Mongodb错误。如果我将mongodb指向另一个数据库(比如Mysql之类的),它可以工作，但不能用于mongodb。

@Configuration
@EnableJpaRepositories(
        basePackages = "com.deanace.oauth2.repository.datasourceOne",
        entityManagerFactoryRef = "entityManagerFactoryBeanOne",

或者，如果有人可以用另一种可能有用的方法来帮助。提前感谢

如果您想将mongodb与JDBC连接起来，您可以在application.properties文件中添加这两行，用于将MongoDB与JDBC连接起来，并排除自动配置。

#connect mongodb with jdbc
spring.data.mongodb.uri=mongodb://localhost:27017/testDb\ 

#exclude jdbc autoconfiguration
spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration

同时在应用程序的main.class中加入@EnableAutoConfiguration注释

@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class, XADataSourceAutoConfiguration.class})

因为Spring引导应用程序的 JPA 自动配置功能尝试使用 JPA 数据源建立数据库连接。Java 类数据源自动配置负责加载 JPA 数据源。可以通过从Spring引导上下文中排除数据源自动配置类来禁用自动配置。

如果我没理解错的话，你是想在JDBC上使用mongoDB。我认为这不是在mongoDB中使用JDBC常见做法。然而，如果你想使用这种方式，有一个统一的JDBC，你可以使用JDBC驱动程序。也看看这个。
