Failed to auto-configure a DataSource: 'spring.datasource.url' is not specified

Question

I have created a basic spring boot application from SPRING INITIALIZR with the Web, MongoDB and JPA dependencies.

When I try to run the spring boot

Answer 1

Since you have added both mongodb and data-jpa dependencies in your pom.xml file, it was creating a dependency conflict like below

org.springframework.boot
spring-boot-starter-data-jpa


org.springframework.boot
spring-boot-starter-data-mongodb

Try removing jpa dependency and run. It should work fine.
