我的主班:
@SpringBootApplication
@EnableAutoConfiguration
@ComponentScan("XXXX")
public class TestClass extends SpringBootServletInitializer{
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(TestClass.class);
}
public static void main(String[] args) throws Exception {
SpringApplication.run(TestClass.class, args);
}
}
我的属性文件:
spring.data.mongodb.uri=jdbc:mongodb://localhost:27017/test

推荐答案
如果您真的想将MongoDB与JDBC一起使用，则可以使用UnityJDBC.请按照以下步骤将库添加到您的应用程序: http://www.unityjdbc.com/mongojdbc/mongo_jdbc.php
If you really want to use MongoDB with JDBC, you can use UnityJDBC. Follow these steps to add the library to your application: http://www.unityjdbc.com/mongojdbc/mongo_jdbc.php
我建议您遵循此指南来在没有JDBC驱动程序的情况下访问MongoDB数据: https ://spring.io/guides/gs/accessing-data-mongodb/
I suggest you to follow this guide to access MongoDB data without a JDBC driver: https://spring.io/guides/gs/accessing-data-mongodb/
