Spring: Why does Bean resolve as null during injecting?

Question

Collegues, i have a bean:

    @Component
    public class BasicAuthAuthorizationInterceptor extends SoapHeaderInterceptor {

        private static final Logger log = LoggerFactory.getLogger(BasicAuthAuthorizationInterceptor.class);

        @Value("#{${accepted.username.pass1}}")
        private Map<String,String> authMap;

        @Override
        public void handleMessage(Message message) throws Fault {
            AuthorizationPolicy policy = message.get(AuthorizationPolicy.class);

            if (policy == null) {
                sendErrorResponse(message, HttpURLConnection.HTTP_UNAUTHORIZED);
                return;
            }

            String username = policy.getUserName();
            String password = policy.getPassword();

            // CHECK USERNAME AND PASSWORD
            if (!checkLogin(username,password)) {

                 sendErrorResponse(message, HttpURLConnection.HTTP_FORBIDDEN);
            }
        }

        public boolean checkLogin(String username, String password) {
            MapUtils.debugPrint(System.out, "Map: " , authMap);

            if (authMap.containsKey(username.trim()) && password.trim().equals(authMap.get(username).trim())) {
                return true;
            }
            return false;
        }
   //some other methods
    }

When i run test case:

@RunWith(SpringJUnit4ClassRunner.class)
 @ContextConfiguration(classes = SpumConfig.class)
public class BasicAuthAuthorizationInterceptorTest {

    private static final Logger log = LoggerFactory.getLogger(BasicAuthAuthorizationInterceptorTest.class);

    @Autowired
    BasicAuthAuthorizationInterceptor basicAuthAuthorizationInterceptor;
    @Test
    public void handleMessage() throws Exception {
       log.info(String.valueOf(basicAuthAuthorizationInterceptor.checkLogin("abc", "321")));
    }}

I receive true and MapUtils.debugPrint method prints all keys and values:

Map: = { abc = 325 java.lang.String cda = 322 java.lang.String sss = Bas3 java.lang.String } java.util.Collections$UnmodifiableMap

But when i compile a jar file, run application and than call web service I recieve

Map:  = null

Why does it happen and how correctly inject map into BasicAuthAuthorizationInterceptor?

Update

    @Configuration
    @ComponentScan(basePackages = {"com.comp.spum"})
    @PropertySource("classpath:spum-${env}.properties")
    public class spumConfig {
      private static final Logger log = LoggerFactory.getLogger(spumConfig.class);

        @Autowired
        Environment environment;
        @Autowired
        spumCommons spumCommons;


  @Bean
    public String appProps() {
        log.info("test.db.url = " + environment.getProperty("test.db.url"));
        return null;
    }

    @Bean public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer()
    { return new PropertySourcesPlaceholderConfigurer();}

    }

Update 2

According to log properties are resolving and basicAuthAuthorizationInterceptor was created:

Answer 1

Quite possibly the jar is not picking up the right path of the property file to begin with. Please validate the path of the property file first.

Then use the spring' PropertySourcesPlaceholderConfigurer to add the right path. You can validate if your application picks up the property file in the server logs when you deploy your application.
