spring-boot properties not @Autowired

Question

I am trying to get a Spring-boot application going and I am not sure what I am doing wrong here. I have a application.properties file at src/main/resources & src/test/r

Answer 1

Your configuration leads to 2 instances of the ConfigurationSettings class and probably one instance overrides the other.

The 'ConfigurationSettings' has the @Component annotation as you are scanning for components (@ComponentScan) this will lead to an instance. You also have a @Bean annotated method which also leads to an instance. The latter is overridden with the first.

In short remove the @Component annotation as that isn't needed because you already have a factory method for this class.

public class ConfigurationSettings { ... }

You should also remove the @PropertySource annotations as Spring-Boot will already load the application.properties for you.

Finally you should not use the @ContextConfiguration annotation on your test class but the @SpringApplicationConfiguration and pass in your application class (not your configuration class!).

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes=OFAC.class)
public class OFAConfigurationTest {

    @Autowired
    private Environment environment;

    @Autowired
    private ConfigurationSettings configurationSettings;

    @Test
    public void testConfigurationLoads() {
        assertNotNull(environment);
        assertNotNull(configurationSettings);
    }

    @Test
    public void testConfigurationSettingValues() {
        assertEquals("Product Name", configurationSettings.getProduct());
        assertEquals("0.0.1", configurationSettings.getVersion());
        assertEquals("2014 Product", configurationSettings.getCopyright());
    } 

This will fix your runtime configuration problems and will let your test use the power of Spring Boot to configure your application.
