I want to create a basic Spring started application and make a get request. I have added Spring JPA, Spring Web dependencies and started running in port 8080, but my application to start. It says " 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 ".
I have not added any database dependency cause I don't require it, Is that mandatory to have database dependency in my project? Here is my pom.xml
<?xml version="1.0" encoding="UTF-8"?>
4.0.0 org.springframework.boot spring-boot-starter-parent 2.3.1.RELEASE com.example java-sample-project 0.0.1-SNAPSHOT java-sample-project Demo project for Spring Boot

You might be having the data dependency in your POM: (or build.gradle)
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
<version>2.3.1.RELEASE</version>
</dependency>
If so, please remove that.
If you include Spring JPA, then yes, it's mandatory.
But you can easily disable the Spring autoconfigration:
spring.autoconfigure.exclude=
org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration, \
org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration, \
org.springframework.boot.autoconfigure.jdbc.DataSourceTransactionManagerAutoConfiguration
Yes it is mandatory. But if you don't want to have a real database running, then use the in-memory database H2. Just add com.h2database:h2 to the dependencies.
