骆驼上下文在应用程序启动后立即启动关闭，没有明显的错误

标签： spring-boot apache-kafka apache-camel

我的spring-boot应用程序启动了从启用了Kafka的Azure事件中心使用的Camel路由。在该应用程序已启动的消息之后，立即记录以下消息：“ INFO o.a.camel.spring.SpringCamelContext-Apache Camel 2.24.0（CamelContext：camel-1）正在关闭”。

然后，所有的机上交换（如果存在）都被Camel路由成功处理，并且最终该路由被关闭（正常），这也终止了该应用程序。

未显示任何错误消息，似乎没有什么错，除了在应用程序启动后立即自动启动关机。...

知道为什么会这样吗？

我已经尝试过Kafka的超时，但是行为没有改变。

我已将日志记录级别设置为TRACE，但仍然看不到为什么启动关机。

在其他应用程序中，我使用以下库：spring-boot-starter，spring-boot-starter-web，azure-servicebus-spring-boot-starter，camel-kafka，camel-spring-boot-starter，camel-undertow -启动器

这是路线开始的方式：

            from("kafka:dummytopic?brokers=dummy.servicebus.windows.net:9093&topic={{event.hubs.hub.magento}}&groupId={{event.hubs.consumer-group}}"
                    + "&consumersCount=1"
                    + "&autoOffsetReset=latest"
                    + "&saslMechanism=PLAIN"
                    + "&securityProtocol=SASL_SSL"
                    + "&sslProtocol=TLSv1.2"
                    + "&sslEnabledProtocols=TLSv1.2"
                    + "&sslEndpointAlgorithm=HTTPS"
                    + "&saslJaasConfig=" + saslJaasConfig
                    + "&autoCommitEnable=true")
.....

通常，路由应继续运行并轮询kafka事件中心以获取事件（并在事件可用时进行处理）。

相反，它立即启动关机（仍然成功处理所有正在进行的交换）-它只是简单地正常关机。没有错误消息。

感谢您的帮助！

我遇到了同样的问题，就我而言，解决方案是将下一个依赖项添加到 pom 文件中。

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

没有使应用程序保持活动状态的线程。这就是为什么它立即关闭的原因。

您可能想添加spring-boot-starter-web以使Web容器正在运行，或者在我们的主类中可能有一个阻止关闭的循环。

我会去买网络容器。因此，您还可以在执行器框架中添加一些诊断信息。

最终，该解决方案成功了：

@Slf4j
@SpringBootApplication
public class NotificationMicroserviceApplication implements CommandLineRunner {

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

    @Override
    public void run(String... args) throws Exception {
        log.info("You can press Ctrl+C anytime to shutdown application");
        Thread.currentThread().join();
    }
}

答案 3 :(得分：0)

这个和spring版本升级有关。

所描述的问题与不同Maven依赖项之间的冲突有关。我在尝试将最新版本的 Spring Boot 与 Apache Camel 一起使用时遇到了同样的问题。

分析依赖树，发现spring-webmvc的版本是5.2.9，其他spring依赖的都是5.2.8版本。

我已经通过使用更新版本的camel-spring-boot-dependencies (3.6.0) 解决了这个问题
