如何为 Camel SJMS2 组件配置连接因子

Question

我对配置 SJMS2 组件的最佳方式感到困惑。我在一个简单的测试应用程序中使用camel-spring-boot-starter，并尝试使用SJMS2 Camel 组件从ProducerTemplate 写入ActiveMQ Artemis。 component documentation 说它处理诸如连接缓存之类的事情，我通常会在我的 ConnectionFactory bean 中配置这些事情，所以我觉得我应该在我的配置中定义比不使用 Camel 时更少的事情。

文档似乎缺少一个清晰的示例，说明如何在使用 Camel Spring 时配置 jsms2 路由及其 ConnectionFactory。在某个地方是否有一个很好的例子，或者有人可以告诉我它的外观吗？这是我当前的测试应用程序：

Spring Boot 应用程序：

@SpringBootApplication
public class WebhookpublisherApplication implements CommandLineRunner {

    @Autowired
    private ProducerTemplate producerTemplate;

    public static void main(String[] args) {
        SpringApplication.run(WebhookpublisherApplication.class, args);
    }

    @Override
    public void run(String... args) throws Exception {
        producerTemplate.sendBody("direct:test", "testBody");
    }
}

路线：

@Component
public class RestToJmsRoute extends RouteBuilder {

    @Override
    public void configure() {
        from("direct:test")
                .log("Recieved a test body: ${body}")
                .to("sjms2:topic:test-topic");
    }
}

JMS Config（显然没有被 Camel 组件使用）

@Configuration
public class JmsConfig {

    @Bean
    public ActiveMQConnectionFactory activeMQConnectionFactory() {
        return new ActiveMQConnectionFactory("tcp://localhost:61616");
    }
}

以上导致以下异常：

原因：java.lang.IllegalArgumentException: ConnectionResource 或 ConnectionFactory 必须为 sjms2://test-topic 配置

Answer 1

我最终添加了以下配置类：

@Configuration
public class CamelContextConfig {

    @Bean
    public CamelContextConfiguration contextConfiguration() {
        return new CamelContextConfiguration() {
            @Override
            public void beforeApplicationStart(CamelContext context) {
                Sjms2Component component = new Sjms2Component();

                ActiveMQConnectionFactory activeMqConnectionFactory = new ActiveMQConnectionFactory("tcp://myArtemisHost:61616");
                activeMqConnectionFactory.setUser("user");
                activeMqConnectionFactory.setPassword("pass");

                component.setConnectionFactory(activeMqConnectionFactory);

                context.addComponent("sjms2", component);
            }

            @Override
            public void afterApplicationStart(CamelContext camelContext) {

            }
        };
    }
}

然后我将我的 pom 依赖项更改为：

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-artemis</artifactId>
