我有一个 Springboot 应用程序，其中配置了一些 Camel 路由。

public class CamelConfig {
    private static final Logger LOG = LoggerFactory.getLogger(CamelConfig.class);

    @Value("${activemq.broker.url:tcp://localhost:61616}")
    String brokerUrl;

    @Value("${activemq.broker.maxconnections:1}")
    int maxConnections;

    @Bean
    ConnectionFactory jmsConnectionFactory() {
        PooledConnectionFactory pooledConnectionFactory = new PooledConnectionFactory(new ActiveMQConnectionFactory(brokerUrl));
        pooledConnectionFactory.setMaxConnections(maxConnections);
        return pooledConnectionFactory;
    }

    @Bean
    public RoutesBuilder route() {
        LOG.info("Initializing camel routes......................");
        return new SpringRouteBuilder() {
            @Override
            public void configure() throws Exception {
                from("activemq:testQueue")
                  .to("bean:queueEventHandler?method=handleQueueEvent");
            }
        };
    }
}

我想测试从activemq:testQueue到的这条路线queueEventHandler::handleQueueEvent。我尝试了这里提到的不同的东西http://camel.apache.org/camel-test.html，但似乎没有让它工作。

我正在尝试做这样的事情：

    @RunWith(SpringRunner.class)
    @SpringBootTest(classes = {CamelConfig.class,   CamelTestContextBootstrapper.class})
    public class CamelRouteConfigTest {

    @Produce(uri = "activemq:testQueue")
    protected ProducerTemplate template;

    @Test
    public void testSendMatchingMessage() throws Exception {
        template.sendBodyAndHeader("testJson", "foo", "bar");
        // Verify handleQueueEvent(...) method is called on bean queueEventHandler by mocking
    }

但我的 ProducerTemplate 始终是null. 我尝试了 auto-wiring CamelContext，但我得到一个异常，说它无法解析 camelContext。但这可以通过添加类SpringCamelContext.class来解决@SpringBootTest。但我ProducerTemplate的还在null。

请建议。我正在使用 Camel 2.18 和 Spring Boot 1.4。

在支持 Spring Boot 2 的 Camel 2.22.0 和正在进行中，您可以使用以下模板来测试您的路由是否支持 Spring Boot 2：

@RunWith(CamelSpringRunner.class)
@SpringBootTest(webEnvironment = WebEnvironment.NONE, classes = {
    Route1.class,
    Route2.class,
    ...
})
@EnableAutoConfiguration
@DisableJmx
@DirtiesContext(classMode = DirtiesContext.ClassMode.AFTER_CLASS)
public class RouteTest {

  @TestConfiguration
  static class Config {
    @Bean
    CamelContextConfiguration contextConfiguration() {
      return new CamelContextConfiguration() {
        @Override
        public void beforeApplicationStart(CamelContext camelContext) {
          // configure Camel here
        }

        @Override
        public void afterApplicationStart(CamelContext camelContext) {
          // Start your manual routes here
        }
      };
    }

    @Bean
    RouteBuilder routeBuilder() {
      return new RouteBuilder() {
        @Override
        public void configure() {
          from("direct:someEndpoint").to("mock:done");
        }
      };
    }

    // further beans ...
  }

  @Produce(uri = "direct:start")
  private ProducerTemplate template;
  @EndpointInject(uri = "mock:done")
  private MockEndpoint mockDone;

  @Test
  public void testCamelRoute() throws Exception {
    mockDone.expectedMessageCount(1);

    Map<String, Object> headers = new HashMap<>();
    ...
    template.sendBodyAndHeaders("test", headers);

    mockDone.assertIsSatisfied();
  }
}

Spring Boot 区分@Configuration和@TestConfiguration。如果在顶级类上注释，则入门级将替换任何现有配置，同时@TestConfiguration将与其他配置一起运行。

此外，在较大的项目中，您可能会遇到自动配置问题，因为您不能依赖 Spring Boot 2 来配置自定义数据库池或不正确的情况，或者在您具有特定目录结构且配置不在其中的情况下一个直接的祖先目录。在这种情况下，可能最好省略@EnableAutoConfiguration注释。为了告诉 Spring 仍然自动配置 Camel，您可以简单地传递CamelAutoConfiguration.class给中提到的类@SpringBootTest

@SpringBootTest(webEnvironment = WebEnvironment.NONE, classes = {
    Route1.class,
    Route2.class,
    RouteTest.Config.class,
    CamelAutoConfiguration.class
}

由于没有执行自动配置，Spring 不会在您的测试类中加载测试配置，也不会初始化 Camel。通过手动将这些配置添加到引导类中，Spring 将为您完成。

对于像这样使用 MQ 和 Spring Boot 的一条路线：

    @Component
    public class InboundRoute extends RouteBuilder {
    
      @Override
      public void configure() {
        JaxbDataFormat personDataFormat = new JaxbDataFormat();
        personDataFormat.setContextPath(Person.class.getPackage().getName());
        personDataFormat.setPrettyPrint(true);
        from("direct:start").id("InboundRoute")
            .log("inbound route")
            .marshal(personDataFormat)
            .to("log:com.company.app?showAll=true&multiline=true")
            .convertBodyTo(String.class)
            .inOnly("mq:q.empi.deim.in")
            .transform(constant("DONE"));
      }
    }

我使用adviceWith来替换端点并且只使用模拟：

    @RunWith(CamelSpringBootRunner.class)
    @UseAdviceWith
    @SpringBootTest(classes = InboundApp.class)
    @MockEndpoints("mock:a")
    public class InboundRouteCamelTest {
    
      @EndpointInject(uri = "mock:a")
      private MockEndpoint mock;
    
      @Produce(uri = "direct:start")
      private ProducerTemplate template;
    
      @Autowired
      private CamelContext context;
    
      @Test
      public void whenInboundRouteIsCalled_thenSuccess() throws Exception {
        mock.expectedMinimumMessageCount(1);
        RouteDefinition route = context.getRouteDefinition("InboundRoute");
        route.adviceWith(context, new AdviceWithRouteBuilder() {
          @Override
          public void configure() {
            weaveByToUri("mq:q.empi.deim.in").replace().to("mock:a");
          }
        });
        context.start();
    
        String response = (String) template.requestBodyAndHeader("direct:start",
            getSampleMessage("/SimplePatient.xml"), Exchange.CONTENT_TYPE, MediaType.APPLICATION_XML);
    
        assertThat(response).isEqualTo("DONE");
        mock.assertIsSatisfied();
      }
    
      private String getSampleMessage(String filename) throws Exception {
        return IOUtils
            .toString(this.getClass().getResourceAsStream(filename), StandardCharsets.UTF_8.name());
      }
    }

我使用以下依赖项：Spring Boot 2.1.4-RELEASE 和 Camel 2.23.2。Github上提供了完整的源代码。

这就是我最终这样做的方式：

    @RunWith(SpringRunner.class)
    public class CamelRouteConfigTest extends CamelTestSupport {
    
        private static final Logger LOG = LoggerFactory.getLogger(CamelRouteConfigTest.class);
        private static BrokerService brokerSvc = new BrokerService();
    
        @Mock
        private QueueEventHandler queueEventHandler;
    
        @BeforeClass
        // Sets up an embedded broker
        public static void setUpBroker() throws Exception {
            brokerSvc.setBrokerName("TestBroker");
            brokerSvc.addConnector("tcp://localhost:61616");
            brokerSvc.setPersistent(false);
            brokerSvc.setUseJmx(false);
            brokerSvc.start();
        }
    
        @Override
        protected RoutesBuilder createRouteBuilder() throws Exception {
            return new CamelConfig().route();
        }
    
        // properties in .yml has to be loaded manually. Not sure of .properties file
        @Override
        protected Properties useOverridePropertiesWithPropertiesComponent() {
            YamlPropertySourceLoader loader = new YamlPropertySourceLoader();
            try {
                PropertySource<?> applicationYamlPropertySource = loader.load(
                    "properties", new ClassPathResource("application.yml"),null);// null indicated common properties for all profiles.
                Map source = ((MapPropertySource) applicationYamlPropertySource).getSource();
                Properties properties = new Properties();
                properties.putAll(source);
                return properties;
            } catch (IOException e) {
                LOG.error("application.yml file cannot be found.");
            }
    
            return null;
        }
    
        @Override
        protected JndiRegistry createRegistry() throws Exception {
            JndiRegistry jndi = super.createRegistry();
            MockitoAnnotations.initMocks(this);
            jndi.bind("queueEventHandler", queueEventHandler);
    
            return jndi;
        }
    
        @Test
        // Sleeping for a few seconds is necessary, because this line template.sendBody runs in a different thread and
        // CamelTest takes a few seconds to do the routing.
        public void testRoute() throws InterruptedException {
            template.sendBody("activemq:productpushevent", "HelloWorld!");
            Thread.sleep(2000);
            verify(queueEventHandler, times(1)).handleQueueEvent(any());
        }
    
        @AfterClass
        public static void shutDownBroker() throws Exception {
            brokerSvc.stop();
        }
    }

您是否尝试过使用 Camel 测试运行器？

@RunWith(CamelSpringJUnit4ClassRunner.class)

如果您使用camel-spring-boot依赖项，您可能知道它使用自动配置来设置 Camel：

CamelAutoConfiguration.java

这意味着您可能还需要添加@EnableAutoConfiguration到您的测试中。
