Encountering a URL error in Spring Boot

Neo4j Graph Platform

We are encountering an issue with the spring boot-up application. Could you please assist us in identifying what we have missed?
What is Java code required?
What are the configurations required in the application.properties file?
Is it dependency correct in pom.xml?

Spring boot version 3.2.4
Java 17
Vaadin 24.3.8
Neo4j-community-4.4.31-windows

Error

APPLICATION FAILED TO START

Description:

Failed to configure a DataSource: 'URL' attribute is not specified and no embedded data source 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).

current use maven dependency for Neo4j in pom.xml

< dependency >
	<groupId>org.springframework.boot</groupId >
	<artifactId>spring-boot-starter-data-neo4j</artifactId >
< /dependency >		
<dependency >
	<groupId>org.springframework.data</groupId >

Why do you have this entry in your properties file?

spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration

Thanks, @glilienfield for your response.
This exclusion of default configuration was recommended by other blogs.

also, we are facing the below warning.

The entity MyEntity is using a Long value for storing internally generated Neo4j ids. The Neo4j internal Long Ids are deprecated, please consider using an external ID generator.
