Exception when configuring MongoDb using Spring -Data

Getting this error during application startup. I am using MongoDb with spring-data. In addition, I use spring boot.

I have lines in the application.properties file.

 spring.data.mongodb.host=127.0.0.1 spring.data.mongodb.port=27017 spring.datasource.driverClassName=com.mongodb.Mongo spring.data.mongodb.database=DigitalDiary spring.data.mongodb.repositories.enabled=true

My Entity (Document), this class is in a different package than the main class.

 @Document(collection = "blood_group_collection") public class BloodGroup { @Id private String _id; @Indexed(unique=true) private String blood_group_type; public BloodGroup(String blood_group_type) { super(); this.blood_group_type = blood_group_type; } public String get_id() { return _id; } public String getBlood_group_type() { return blood_group_type; } public void setBlood_group_type(String blood_group_type) { this.blood_group_type = blood_group_type; } }

My class is MongoRepository. This class is in different packages than the class of the main class and the object (document).

 public interface BloodGroupRepository extends MongoRepository<BloodGroup, String>{ }

I have @EnableMongoRepositories ("com.awt.mongo.repository") in the main class.
I can not find a solution.
Any help would be appreciated. Thanks.

The exception was due to spring jpa. I removed spring -jpa dependency on pom.xml and solved my problem. Thank you all for your help and quick response.

It’s clear from your error that your data source is not configured correctly:

"Caused by: org.springframework.beans.BeanInstantiationException: could not instantiate [javax.sql.DataSource]: Factory method 'dataSource' threw an exception; nested exception - org.springframework.beans.factory.BeanCreationException: Can not define a driver class embedded databases for the NONE database type, if you want the embedded database to host the supported one in the classpath.

I suspect a line that states:

 spring.datasource.driverClassName=com.mongodb.Mongo

false - it looks like a JDBC driver, but since MongoDB is a NoSQL database, its driver does not meet the same standards.

The spring documentation offers the following properties for MongoDB:

 spring.data.mongodb.host= # the db host spring.data.mongodb.port=27017 # the connection port (defaults to 27107) spring.data.mongodb.uri=mongodb://localhost/test # connection URL spring.data.mongodb.database= spring.data.mongodb.authentication-database= spring.data.mongodb.grid-fs-database= spring.data.mongodb.username= spring.data.mongodb.password= spring.data.mongodb.repositories.enabled=true # if spring data repository support is enabled

I removed the <version> in the POM file, the problem is fixed

I added the following dependency

  • Jdbc addiction
  • Spring-JPA dependency

my problem was resolved when I removed both dependencies
