spring-boot datasource profiles w/ application.properties

Question

Updated Question based upon feedback:

I have a spring-boot application that has three databases: H2 for integration testing, and Postgresql for qa & production. Since spring-boot creates a default datasource for you, I don't have anything defined for my integration tests. I thought I would use application.properties to define my datasource connection values but I am not certain what is the best way to handle this.

I have two files:

src/main/resources/application.properties

spring.profiles.active=production
appName = myProduct
serverPort=9001

spring.datasource.url=jdbc:postgresql://localhost/myDatabase
spring.datasource.username=user
spring.datasource.password=password
spring.datasource.driverClassName=org.postgresql.Driver

spring.jpa.hibernate.hbm2ddl.auto=update
spring.jpa.hibernate.ejb.naming_strategy=org.hibernate.cfg.EJB3NamingStrategy
spring.jpa.hibernate.show_sql=true
spring.jpa.hibernate.format_sql=true
spring.jpa.hibernate.use_sql_comments=false
spring.jpa.hibernate.type=all
spring.jpa.hibernate.disableConnectionTracking=true
spring.jpa.hibernate.default_schema=dental

src/main/resources/application-test.properties

spring.profiles.active=test
serverPort=9002

spring.datasource.url = jdbc:h2:~/testdb
spring.datasource.username = sa
spring.datasource.password = 
spring.datasource.driverClassName = org.h2.Driver

liquibase.changeLog=classpath:/db/changelog/db.changelog-master.sql

I used to run my tests with with gradle (using "gradle build test") or within IntelliJ. I updated my gradle file to use:

task setTestEnv {
    run { systemProperty "spring.profiles.active", "test" }
}

But when I run gradle clean build setTestEnv test I get errors that seem to indicate the test is trying to connect to an actual Postgresql database:

Caused by: org.postgresql.util.PSQLException: Connection refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.

I haven't figured out how to set the default system.property == "test" within IntelliJ yet...

Answer 1

You can annotate your tests adding @ActiveProfiles in the following way:

@SpringApplicationConfiguration(classes = {Application.class, TestSpringConfiguration.class})
@Test(groups = "integration")
@ActiveProfiles("test")
public class MyServiceTest extends AbstractTransactionalTestNGSpringContextTests {
...
   @Test 
   public void testSomething() {
      ...
   }
} 

I'm using TestNG but JUnint wouldn't be much different. You can also specify additional configuration as showed in the example above.

That way you won't need to set the profile in build.gradle or launch configuration in IntelliJ

Answer 2

See section 21.3 of the Spring Boot documentation. This section describes how to define profile specific property files that use the format application-{profile}.properties. This can help you isolate properties on a per profile basis.
