Spring boot: how to read specific property from application.yml and ignore others

Question

My goal is to read some property from application.yml file and ignore other properties. This is need for testing purposes - I want to read part of config and validate it. I want to ignore other properties because Spring Boot tring to handle it but this is no need for my test. Example.

Config:

first:
 property:
  {cipher}value    #for example Spring trying to handle cipher and throws exception

second:
 property:
  value

Class ( using String for simplification ):

@Configuration
public class Configuration {

  @Bean
  @ConfigurationProperties(prefix = "second.property")
  public String secondProperty() {
      return new String();
  }
}

Test class:

@SpringBootTest
public class ConfigPropertiesCheckerIntegrationTest {

    @Autowired
    String secondProperty;

    @Test
    void checkAutoConfigEndpointProperties() {
        assertThat(secondProperty, is(notNullValue()));
    }
}

So question: how to ignore first.property and say Spring just skip it?

You can disable {cipher} ed properties decryption with spring.cloud.decrypt-environment-post-processor.enabled=false . Eg:

@SpringBootTest(properties = "spring.cloud.decrypt-environment-post-processor.enabled=false")
