Spring Source objects loaded but not applied in tests

Question

I have a wired problem and cannot find any advice in it.

I am working on setting up a database configuration with property files. I got a class that is responsible for loading these properties:

@Component
@PropertySources(value = *arrayOf(
    PropertySource("classpath:/dbconfig/base.properties"),
    PropertySource("classpath:/dbconfig/override.properties", ignoreResourceNotFound = true)
))
@ConfigurationProperties("groups.datasource")
class DbConfig {
  val base: List<DataSourceProperties> = ArrayList()
  val override: List<DataSourceProperties> = ArrayList()
}

Then I use this component in the configuration class to configure my data.

Here is my src / main / resources / dbconfig / base.properties file:

#Spring Boot Config for Oracle
# CENTRAL
groups.datasource.base[0].name=central
groups.datasource.base[0].url=jdbc:oracle:thin:@url:1530:sid
groups.datasource.base[0].username=user
groups.datasource.base[0].password=passwd
groups.datasource.base[0].driver=class name=oracle.jdbc.driver.OracleDriver

And the src / test / resources / dbconfig / override.properties file:

#Spring Boot Config for Oracle
# PREPROD
groups.base.override[1].name=preprod
groups.base.override[1].url=jdbc:oracle:thin:@user:1542:sid
groups.base.override[1].username=user
groups.base.override[1].password=passwd
groups.base.override[1].driver=class name=oracle.jdbc.driver.OracleDriver

And here is my test class:

@RunWith(SpringJUnit4ClassRunner::class)
@SpringBootTest(classes = arrayOf(DatabaseComponent::class))
open class DatabaseComponentTest {

  @Autowired
  lateinit var env: Environment

  @Test
  fun testBaseConfiguration() {
    assert(env.getProperty("groups.datasource.base[0].name") == "central")
    assert(env.getProperty("groups.datasource.base[0].url") == "jdbc:oracle:thin:@url:1530:sid")
    assert(env.getProperty("groups.datasource.base[0].username") == "user")
    assert(env.getProperty("groups.datasource.base[0].password") == "passwd")
    assert(env.getProperty("groups.datasource.base[0].driver") == "class name=oracle.jdbc.driver.OracleDriver")
  }

  @Test
  fun testOverrideConfiguration() {
    assert(env.getProperty("groups.datasource.override[0].name") == "preprod")
    assert(env.getProperty("groups.datasource.override[0].url") == "jdbc:oracle:thin:@url:1542:sid")
    assert(env.getProperty("groups.datasource.override[0].username") == "user")
    assert(env.getProperty("groups.datasource.override[0].password") == "passwd")
    assert(env.getProperty("groups.datasource.override[0].driver") == "class name=oracle.jdbc.driver.OracleDriver")
  }

}

In debug mode, when I look at the Loader class, the override.properties file seems to be loaded with all its values.

Also, testBaseConfiguration really works, and state true. For now, testOverrideConfiguration does not, and state false.

, Spring, . .

1: DataBaseComponent:

@Configuration
@EnableAutoConfiguration
@ComponentScan
open class DatabaseComponent

Answer 1

Try

@Test   fun testOverrideConfiguration() {     assert (env.getProperty( "groups.datasource.override [1].name" ) == "preprod" )     assert (env.getProperty( "groups.datasource.override [1].url" ) == "jdbc: oracle: thin: @url: 1542: sid" )     assert (env.getProperty( "groups.datasource.override [1].username" ) == "user" )     assert (env.getProperty( "groups.datasource.override [1].password" ) == "passwd" )     assert (env.getProperty( "groups.datasource.override [1].driver" ) == "class name = oracle.jdbc.driver.OracleDriver" )   }

, [0] [1] testOverrideConfiguration() us [0] override.properties
