Spring Boot Apache Camel路由测试

我有一个Springboot应用程序，在其中配置了一些骆驼路线。

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");
             }
    };
}

}

我想测试一下从activemq：testQueue到queueEventHandler :: handleQueueEvent的路由，

我尝试了这里提到的其他事情http://camel.apache.org/camel-

test.html，但是似乎没有起作用。

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
}

但是我的ProducerTemplate始终为null。我尝试了自动装配Camelcontext，对此我遇到了一个异常，说它无法解析camelContext。但这可以通过将SpringCamelContext.class添加到@SpringBootTest类来解决。但是我的ProducerTemplate仍然为null。

请提出建议。我正在使用骆驼2.18 Springboot 1.4

回答：

这就是我最终做到的方式

@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 a 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();
    }
}
