DataSourceBeanCreationException: Failed to determine a suitable driver class. How to establish connection to the mongoDB from spring?

I try to implement the spring-boot project with mongoDB.
The mongoDB isn't installed locally - I use docker image for this task.
So:
docker run -d --name mongodb -e MONGO_INITDB_ROOT_USERNAME=root -e MONGO_INITDB_ROOT_PASSWORD=pass -p 27017:27017
docker image installed successfully and I able to enter into docker shell with
docker exec -it {conteinerId} bash
Now, I try to execute spring-boot application.
application.properties:
spring.data.mongodb.database=proxy_db
spring.data.mongodb.host=localhost
spring.data.mongodb.username=root
spring.data.mongodb.password=pass
spring.data.mongodb.port=27017

After launching I received warning:
2023-01-30 19:53:41.941 WARN 12208 --- [ restartedMain] ConfigServletWebServerApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'dataSourceScriptDatabaseInitializer' defined in class path resource [org/springframework/boot/autoconfigure/sql/init/DataSourceInitializationConfiguration.class]: Unsatisfied dependency expressed through method 'dataSourceScriptDatabaseInitializer' parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.zaxxer.hikari.HikariDataSource]: Factory method 'dataSource' threw exception; nested exception is org.springframework.boot.autoconfigure.jdbc.DataSourceProperties$DataSourceBeanCreationException: Failed to determine a suitable driver class
And as result, error:
APPLICATION FAILED TO START
Description:
Failed to configure a DataSource: 'url' attribute is not specified and
no embedded datasource could be configured.
Reason: Failed to determine a suitable driver class
As I understand - the spring can't establish the connection with the database.
So, how to correctly manage MongoDB in the spring-boot + docker?

You are using the wrong property names, eg url, hence "Failed to configure a DataSource: 'url' attribute is not specified."
Try these:
spring.datasource.url = mongodb://localhost:27017/proxy_db
spring.datasource.username = root
spring.datasource.password = password
Optionally you may need this:
spring.datasource.driver-class-name = com.mongodb.Mongo
Also there appear to be missing/incorrect dependencies:
<!-- https://mvnrepository.com/artifact/org.mongodb/mongo-java-driver -->
<dependency>
<groupId>org.mongodb</groupId>
<artifactId>mongo-java-driver</artifactId>
<version>3.12.11</version>
</dependency>

Manually connecting mySQL to eclipse/Spring Boot

I wanted to ask if I need to specify a path to my SQL file when using eclipse and spring Boot? I am given the same error Cannot determine embedded database driver class for database type NONE. All the settings are right, I believe, but the problem is that I never told eclipse where my databases are?
I do have a properties file that states this:
spring.jpa.hibernate.ddl-auto=create-drop
spring.datasource.url=jdbc:mysql://localhost:3306/db_example
spring.datasource.username=springuser
spring.datasource.password=ThePassword
spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQLDialect
Is this a way for it to find the db_example, and should it somehow be online when I start my project? When i go to localhost:3306 it also shows an error. I haven't been able to solve this problem in 2 days, and am pretty new to programming so please bear with me!

I dont see your application.properties in the resource folder. Your application.properties is in the test environment instead. i wont work like that.

Please change spring.datasource.driverClassName=com.mysql.jdbc.Driver to this spring.datasource.driver-class-name=com.mysql.jdbc.Driver.
Your final database config may like this:
spring.jpa.hibernate.ddl-auto=create-drop
spring.jpa.database-platform = org.hibernate.dialect.MySQLDialect
spring.datasource.url=jdbc:mysql://localhost:3306/db_example
spring.datasource.username=springuser

It seems like Jackson libraries not available for this boot project.
Either add Jackson libraries manually or add the following dependencies which will internally import Jackson libraries.

I solved the problem by excluding hibernate-validator dependency in pom.xml. It is working fine without any issues.

Resolved the issue by adding the below dependency for Jackson:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-autoconfigure</artifactId>
<version>1.2.1.RELEASE</version>
</dependency>
Also make sure to remove classpath entries for Jackson

Spring Boot JAR built with Maven using requiresUnpack not working

I think I have been running into the following issue Jersey doesn't always work with Spring Boot fat jars. The workaround should be to set the Jersey dependencies in the POM to requiresUnpack.
My POM looks like this:

But I still get the following error when I try to run the JAR that I built with mvn package:
2017-01-13 10:44:28.229 ERROR 9289 --- [ost-startStop-1] o.s.b.c.embedded.tomcat.TomcatStarter : Error starting Tomcat context.

Running the JAR that I built in IDE with Artifacts works just fine.
Is there something wrong in my POM or the way I build the JAR with Maven?

This might have been fixed already. I have published a couple of blog posts related to Creating APIs using Spring Boot, Jersey 2 and Docker and documenting them using Swagger available at: http://tech.asimio.net/2016/04/05/Microservices-using-Spring-Boot-Jersey-Swagger-and-Docker.html and http://tech.asimio.net/2016/05/07/Documenting-multiple-REST-API-versions-using-Spring-Boot-Jersey-and-Swagger.html, both with accompanying source code and I didn't need to unpack and repackage Jersey 2 dependencies.
On the other hand, when I was working on the accompanying source code for another blog about Services Registration and Discovery using Spring Cloud, Eureka, Ribbon and Feign, I was integrating Spring Boot and Jersey 1 (Jersey 1 doesn't have a Spring Boot starter I do recall to work-around unpackaging Jersey 1 dependencies a needed to create a multi-module Maven project for that specific API service.

The problem is that Jersey cannot scan classes in the new "fat boot jar". This occurs when you try to use the packages("some.package.to.scan") method of the ResourceConfig class.
However, you can achive the same effect using Spring classpath scanning facilities. This way you can scan a package similarily to config.packages():
ClassPathScanningCandidateComponentProvider scanner = new ClassPathScanningCandidateComponentProvider(false);
scanner.addIncludeFilter(new AnnotationTypeFilter(Provider.class));
scanner.addIncludeFilter(new AnnotationTypeFilter(Path.class));
config.registerClasses(scanner.findCandidateComponents("your.package.to.scan").stream()
.map(beanDefinition -> ClassUtils.resolveClassName(beanDefinition.getBeanClassName(), config.getClassLoader()))
.collect(Collectors.toSet()));
Note: please have a look at the source of org.glassfish.jersey.server.internal.scanning.AnnotationAcceptingListener. This is the stock solution and you can see that it does the same: it scans for classes annotated with #Path or #Provider (but doesn't manage to find anything because of the broken scanning mechanism).
(Using the older version of the boot plugin worked for me too, but I tried to avoid it.)

I found the issue.
Spring Boot 1.4 changed the internal Jar Structure to facilitate the
Spring Boot bootstrap process.
https://github.com/spring-projects/spring-boot/issues/1468#issuecomment-267357809
You can leave this version 1.4.3:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.4.3.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
But spring-boot-jersey fat-jar to be executable without errors it`s need to downgrade plugin version to 1.3.8 like this:
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<version>1.3.8.RELEASE</version>

I have succeed to create the Spring project with intellij. But even if the project is 'empty', i haven't changed anything yet, i can't do a maven install it.

Maybe i need some kind of properties somewhere but i don't know which ones and where to put them...

I found what was the problem !
So it was that i didn't configure something as you said. I didn't needed to install the jdbc (i don't know why i don't need it) but just to put some properties on the file : /main/ressources/application.properties
spring.jpa.database=POSTGRESQL
spring.datasource.platform=postgres
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=create-drop
spring.database.driverClassName=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost:5432/mybase
spring.datasource.username=username
spring.datasource.password=mdp
Thx for the answers anyway :)

You are missing DB JAR on your classpath. If you are using
Maven/Gradle, just include JDBC driver dependency into your POM/gradle
file.
Taken from here:
Spring Boot: Unable to configure
As first try to add the dependency to your pom:
<!-- ORACLE database driver -->
<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc6</artifactId>
<version>11.2.0</version>
</dependency>
Then if it does not work add it manually with the "mvn install:install-file" goal..
