Java 在spring Camel Dsl路由类中使用Mockito mockbean编写junit测试会给出null

我正在使用增强的驼峰弹簧测试来测试我的驼峰路线。 我有一个类MyCamelRoutes，它包含我的骆驼路线

@Component
@RefreshScope
public class MyCamelRoutes extends RouteBuilder {

  @Autowired  Environment env;

  @Autowired  ApplicationContext appcontext;

  @Override
  public void configure() throws Exception {

    logger.info("env = {} and its applicationcontext = {}:end",env,appcontext);
    
    String fileDir = env.getProperty("myfile.dir");

    String noopisactive = env.getProperty("myfile.noop");
    
    String kafkatopic = env.getProperty("mykafka.topic");

    String linger = env.getProperty("mykafka.linger");
     int lingerinms = Integer.parseInt(linger);
    
    from("file://"
            + fileDir
            + "?"
            + "noop="
            + noopisactive)
         
        .routeId("FileTaker")
        .startupOrder(1)
        .to("direct:processFile");
 
   //PROCESS
    from("direct:processFile")
        .routeId("FileProcessor")
        .startupOrder(2)
        .transform()
        .method(new myworker(), "process")
        .to("direct:mykafka");

   //KAFKA ROUTE
    from("direct:mykafka")
        .routeId("KafkaSender")
       .startupOrder(3)
        .log("Sending to zester kafka");
        .to("kafka:" + kafkatopic+ "?lingerMs="+lingerinms)
        .log("data sent to kafka.")
        .end()
        .stop();
  }
}

我已经为此创建了单元测试，如下所示：

@ImportAutoConfiguration(RefreshAutoConfiguration.class)
@RunWith(CamelSpringBootRunner.class)
//@RunWith(SpringRunner.class)
@SpringBootTest
@ContextConfiguration
@DirtiesContext
@MockEndpoints("kafka:zester")
@MockBeans(@MockBean(Environment.class))
class MyCamelRoutesTest {
    
    @EndpointInject(uri = "mock:kafka:zester")
    MockEndpoint kafkamock;

    @Autowired
    ProducerTemplate template;
    
//    @Autowired
//    CamelContext ccontext;
//    
    @InjectMocks
    MyCamelRoutes routes;
    
    @Autowired
    Environment env;
    
    @BeforeTestClass
    public void setUp() throws Exception {  
        MockitoAnnotations.initMocks(this); 
        when(env.getProperty("myfile.dir")).thenReturn("D:/zesterFiles");
        when(env.getProperty("myfile.noop")).thenReturn("true");
        when(env.getProperty("mykafka.topic")).thenReturn("zester");
        when(env.getProperty("mykafka.linger")).thenReturn("2000");
            
    }

    @Test
    void sampleMockTest() throws InterruptedException, FileNotFoundException {
        
        File file = ResourceUtils.getFile(
                "zesterFile1.csv");
        template.sendBody("file://D:/zesterFiles",file);
        kafkamock.expectedMessageCount(1);
        kafkamock.assertIsSatisfied();
    }
}

当我试图从环境mock bean中获取值时，我得到了一个NullPointerException，即使我已经截短了正确的值。在调试模式下，我可以在Route实例中看到模拟bean，但是没有存根，因此它返回null，当解析null时，它给出NPE。 我使用的是SpringBoot2.3.0，Camel版本是3.2.0，JUnit5。谁能告诉我可能做错了什么，我如何才能让它工作
