Spring Error LoggingFailureAnalysisReporter after Initialize new project

i made a new project with Spring Initializr and run it after import in the Intellij without any change in the code that generated by the IDE and i get the following error :

restartedMain] o.s.b.d.LoggingFailureAnalysisReporter

***************************
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


Action:

Consider the following:
If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
If you have database settings to be loaded from a particular profile you may need to 
activate it (no profiles are currently active).

MariaDB version: 10.3.23

Spring Ver: 2.3.2

Java Ver: openjdk 1.8.0_252

Solution

This Error comes from bad database configuration of the application.properties under the: /src/main/resources read the: this github repo for knowing all the setting that you can and should use in the application.properties but for your simple project use the below instruction:

add this lines of code to the application.properties:

# ===============================
# = DATA SOURCE
# ===============================

# Set here configurations for the database connection

# Connection url for the database "netgloo_blog"
spring.datasource.url = jdbc:mysql://localhost:3306/netgloo_blog?useSSL=false

# Username and password
spring.datasource.username = root
spring.datasource.password = root

# Keep the connection alive if idle for a long time (needed in production)
spring.datasource.testWhileIdle = true
spring.datasource.validationQuery = SELECT 1

# ===============================
# = JPA / HIBERNATE
# ===============================

# Use spring.jpa.properties.* for Hibernate native properties (the prefix is
# stripped before adding them to the entity manager).

# Show or not log for each sql query
spring.jpa.show-sql = true

# Hibernate ddl auto (create, create-drop, update): with "update" the database
# schema will be automatically updated accordingly to java entities found in
# the project
spring.jpa.hibernate.ddl-auto = update

# Naming strategy
spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy

# Allows Hibernate to generate SQL optimized for a particular DBMS
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

this basic configuration will get you out of trouble but remember to change the username and password for your MySQL or MariaDB Database. you can use this topic for more information about change User and Pass for Database in spring and jhipster projects
