Camel ActiveMQ+Spring Boot未读取Spring ActiveMQ配置

Question

null

如能提供任何协助，将不胜感激。我确实在stackoverflow上搜索了相关的问题，但没有给出我所面临的问题的解决方案

我在控制台上看到错误，这继续像60-70次尝试和计数。正如您所看到的，camel正在获取的代理URL，可能是spring在默认情况下配置的默认URL

Failed to connect to [tcp://localhost:61616] after: 10 attempt(s) continuing to retry.

以下是我当前的配置/代码：

首先，您应该将spring-boot-starter-activeMQ依赖项添加到pom.xml中。然后，您可以使用它的自动配置功能，它将根据您在application.yml中指定的属性创建ConnectionFactory。

之后，还必须配置Camel的ActiveMQComponent。如果您希望重用ConnectionFactory（由autoconfig创建），那么可以通过以下方法实现：

@Configuration
public class ActiveMQComponentConfig {

    @Bean(name = "activemq")
    public ActiveMQComponent createComponent(ConnectionFactory factory) {
        ActiveMQComponent activeMQComponent = new ActiveMQComponent();
        activeMQComponent.setConnectionFactory(factory);
        return activeMQComponent;
    }
}

您可以在Camel的ActiveMQ文档中找到更多信息。
