Question

i try to connect my spring boot application to mongodb, but i get a connection error with the driver class. Here a part of code.

my pom.xml:

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

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

My main class:

@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);
 }
}

my properties file:

spring.data.mongodb.uri=jdbc:mongodb://localhost:27017/test
spring.datasource.driver-class-name=mongodb.jdbc.MongoDriver

a part of a log:

Any ideas about this problem? What is wrong in my project? Can someone help me?

Thanks for helping. Cheers

• andyb: Java cannot find the mongodb.jdbc.MongoDriver at runtime. What does the rest of the pom look like? Also how are you running this?
• Andy Wilkinson: Using JDBC with MongoDB is rather unusual. Are you sure that's what you want to do? If so, it looks like you'll need to use unityjdbc.com/mongojdbc/mongo_jdbc.php
• emoleumassi: if i doesn't use, what can i use. Do you have a recommandation for me?

Answer 1

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

I suggest you to follow this guide to access MongoDB data without a JDBC driver: https://spring.io/guides/gs/accessing-data-mongodb/
