【问题描述】：

我尝试将我的 Spring Boot 应用程序连接到 mongodb，但我收到驱动程序类的连接错误。这里是代码的一部分。

我的 pom.xml：

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.3.1.RELEASE</version>
    </parent>

    <properties>
        <java.version>1.8</java.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-mongodb</artifactId>
        </dependency>
        <dependency>
            <groupId>org.mongodb</groupId>
            <artifactId>mongo-java-driver</artifactId>
        </dependency>
    </dependencies>

我的主要课程：

@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
spring.datasource.driver-class-name=mongodb.jdbc.MongoDriver

关于这个问题的任何想法？我的项目有什么问题？有人可以帮我吗？

感谢您的帮助。 干杯

【问题讨论】：

Java 在运行时找不到mongodb.jdbc.MongoDriver。 pom的其余部分是什么样的？另外你是怎么运行这个的？

在 MongoDB 中使用 JDBC 是相当不寻常的。你确定那是你想做的吗？如果是这样，您似乎需要使用unityjdbc.com/mongojdbc/mongo_jdbc.php

如果我不使用，我可以使用什么。你对我有什么建议吗？

【参考方案1】：

如果你真的想使用 MongoDB 和 JDBC，你可以使用 UnityJDBC。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

我建议您按照本指南在没有 JDBC 驱动程序的情况下访问 MongoDB 数据：https://spring.io/guides/gs/accessing-data-mongodb/
