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

Go to resources folder where the application.properties is present, update the below code in that.

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

Answer 2

In gradle build i simply:

compile('org.springframework.boot:spring-boot-starter-data-jpa') compile('org.springframework.boot:spring-boot-starter-security') compile('org.springframework.boot:spring-boot-starter-web') compile('org.springframework.boot:spring-boot-devtools')

removed

**`compile('org.springframework.boot:spring-boot-starter-data-jpa')`**

and it worked for me.

Answer 3

This error occurred when you are putting JPA dependencies in your spring-boot configuration file like in maven or gradle. The solution is: Spring-Boot Documentation

You have to specify the DB connection string and driver details in application.properties file. This will solve the issue. This might help to someone.

Answer 4

Add the line below in application.properties file under resource folder and restart your application.

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

Answer 5

I encountered this error simply because I misspelled the spring.datasource.url value in the application.properties file and I was using postgresql:

Problem was: jdbc:postgres://localhost:<port-number>/<database-name>

Fixed to: jdbc:postgresql://localhost:<port-number>/<database-name>

NOTE: the difference is postgres & postgresql, the two are 2 different things.

adding org.apache.derby dependency solved my issue.

<dependency>
            <groupId>org.apache.derby</groupId>
            <artifactId>derby</artifactId>
            <scope>runtime</scope>
        </dependency>
