camel ActiveMQ + Spring Boot无法读取Spring ActiveMQ配置

spring-boot

我正在尝试使用Spring Boot 1.5.2.RELEASE + Camel(Spring Boot Starter)+
ActiveMQ进行非常简单的路由,该路由是从特定队列中读取然后进行记录。但是,看起来好像没有在URL中获取我的spring.activemq配置,正如我在日志中看到的那样,它正在尝试连接到另一个url,并且它将继续连接它,而我的spring
boot应用程序永远不会启动。这些问题基于我在下面提供的配置,该如何执行以下操作:

  1. 修复配置以允许spring的activemq配置
  2. 配置maxReconnectAttempts,以便在URL不可访问时不会尝试永久连接,如果ActiveMQ实例关闭,则可能会永久连接

任何帮助将不胜感激。我确实在stackoverflow上搜索了相关问题,但没有一个给我解决所面临问题的解决方案

我在控制台上看到错误,并且仍然喜欢60-70次尝试和计数。如您所见,camel要拾取的代理URL是一些默认的URL,可能是spring默认配置的

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

这是我当前的配置/代码:

spring:

JAVA中的camel路线

package com.mycamel.route;

import org.apache.camel.builder.RouteBuilder;
import org.springframework.stereotype.Component;

@Component
public class SampleAmqCamelRouter extends RouteBuilder {

    @Override
    public void configure() throws Exception {
        from("activemq:some.queue").to("log:com.mycamel.route?level=INFO&groupSize=10");
    }

}

首先,您应该将spring-boot-starter- activemq依赖项添加到pom.xml中。然后,您可以使用其自动配置功能,该功能将ConnectionFactory根据您在application.yml中指定的属性创建一个。

之后,您也必须配置骆驼ActiveMQComponent。如果您想重复使用ConnectionFactory(由自动配置创建的),则可以通过以下方式实现:

@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。
