spring-boot application without a datasource

Is it possible to create a spring-boot application that has NO datasource? In my case i just need a simple REST app but it seems on start up that there is an attempt to auto initialise a datasource

My pom.xml is

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

            </plugin>
        </plugins>
    </build>
</project>

My application.properties is

server.contextPath=/rest-customer-builder
server.port=9090

When i run

mvn clean install spring-boot:run

i see this error

Basically I did the same thing as @Rocky wrote above in .properties file and it works.

spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration,org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration

as for Spring Boot current version (2.5.4) you can put it on the @SpringBootApplication annotation like that:

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class})
public class YourApplication {
public static void main(String[] args) {
    SpringApplication.run(YourApplication.class, args);
}

I had this issue, Once I have removed below dependency it started working.

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

It is possible to run a spring boot application without datasource. You must disable the auto configuration for the datasource and may be for JPA also :

@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class,HibernateJpaAutoConfiguration.class})

The exception you posted is something else, as written in the comments, you have something in the classpath that references the missing class of apache geronimo. So you must get rid of the code/jar that references geronimo or add geronimo to your dependencies.

@Stefan +1 If you are using YAML file for configuration this is how it is

spring:
  profiles: dev
  autoconfigure:
    exclude:
    - org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration
    - org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration

It worked perfectly fine for me.

Provide spring.datasource.url in the application.properties file. It worked for me. Example: spring.datasource.url=jdbc:mysql://localhost/Test_DB

A better way to fix this point will be to remove the dependencies from your POM/Gradle configuration file and Spring Boot will not try to auto configure the DataSource.
