DataSourceBeanCreationException: Failed to determine a suitable driver class. How to establish conne-CodePudding

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?

CodePudding user response：

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
