我正在使用Sping Boot 2.7.15,JDK 17
在pom.xml中添加Spring Data JPA,mongo-db依赖项用于数据库通信
我看到了一些解决方案,但我没有一个应用程序.yml文件来更改'url'

Description:
Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.
Reason: Failed to determine a suitable driver class
Action:
Consider the following:
If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

这是我的应用程序。yml
spring:
data:
mongodb:
uri: mongodb://userAdmin:admin@localhost:27017/?authMechanism=DEFAULT
database: microservices
server:
port: 8083
package com.lcwd.rating;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class RatingServiceApplication {
public static void main(String[] args) {
SpringApplication.run(RatingServiceApplication.class, args);
}
}
的字符串
到目前为止,只有数据库配置添加在项目中,但当我运行项目时,我得到标题中提到的错误。
也可以尝试使用uri,如下所示
mongodb://userAdmin:admin@localhost:27017
型
也可以尝试使用application.properties而不是application.yml
仔细检查用户名、密码、主机、端口号和数据库是否存在。
重新启动Intellij并再次运行。
检查stackoverflow问题,在谷歌上搜索,参考文章,也尝试使用chatGPT。

说明:使用mongdb数据库时,不需要spring-boot-starter-data-jpa依赖,因为JPA(Java Persistence API)是管理关系型数据库的规范,MongoDB是一种NoSQL数据库。MongoDB使用与传统关系型数据库不同的数据模型和查询语言。
**解决方案:**只要从pom.xml中删除下面的依赖项,它就会正常工作。
