spring boot mongodb connection error

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>
        <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>

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

Java cannot find the mongodb.jdbc.MongoDriver at runtime. What does the rest of the pom look like? Also how are you running this? — andyb

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 — Andy Wilkinson

if i doesn't use, what can i use. Do you have a recommandation for me? — emoleumassi

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/
