Spring Data MongoDB does not have a dedicated "authentication database" like other database management systems. Instead, it relies on the authentication mechanisms provided by MongoDB itself.
Authentication in MongoDB
MongoDB uses a user-based authentication system where users are defined within the database itself. Each user has a set of roles and permissions that control access to different databases, collections, and documents.
Spring Data MongoDB and Authentication
When using Spring Data MongoDB, you can configure your application to use MongoDB's authentication system. This involves:
- Specifying the authentication credentials: This usually includes the username, password, and database name.
- Configuring the MongoDB driver: The driver needs to be told how to authenticate to the MongoDB server.
Example: Using Spring Boot with Spring Data MongoDB
Here's a basic example of how to configure authentication in a Spring Boot application:
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
@Bean
public MongoClient mongoClient() {
return MongoClients.create(
"mongodb://username:password@host:port/database"
);
}
}In this example, you would replace username, password, host, port, and database with your actual MongoDB credentials.
Key Points to Remember
- Spring Data MongoDB does not have a separate authentication database.
- You need to configure your Spring Data MongoDB application to use MongoDB's built-in authentication.
- This involves providing the necessary credentials and configuring the MongoDB driver.
