Camel ActiveMQ + Spring boot 不读取 spring activemq 配置 [英] Camel ActiveMQ + Spring boot not reading spring activemq configurations

问题描述

我正在尝试使用 Spring Boot 1.5.2.RELEASE + Camel (Spring Boot Starter) + ActiveMQ 的一个非常简单的路线，即从特定队列中读取然后记录它.但是，它似乎没有为 URL 获取 spring.activemq 配置，正如我在日志中看到的那样，它正在尝试连接到不同的 URL，并且它继续连接它，而我的 Spring Boot 应用程序从未启动.这些问题基于我在下面提供的配置，我该如何执行以下操作:

I am trying a very simple route with Spring Boot 1.5.2.RELEASE + Camel (Spring Boot Starter) + ActiveMQ, which is to read from a particular queue and then log it. However, it looks like it is not picking up my spring.activemq configuration for URL as I see in the log it is trying to connect to a different url and it continues to connect it and the my spring boot app never starts. The questions are based on my configuration that I am providing below how can I do the below:

1. 修复配置以允许spring的activemq配置
2. 配置 maxReconnectAttempts 以便在 URL 不可访问时它不会尝试永远连接，如果 ActiveMQ 实例出现故障，这可能是可能的

任何帮助将不胜感激.我确实在 stackoverflow 上搜索了相关问题，但没有人给我解决我面临的问题

Any assistance would be greatly appreciated. I did search relevant questions on stackoverflow but none gave me a solution to the issue I am facing

我在控制台上看到的错误，这继续像 60-70 次尝试和计数.如您所见，camel 获取的代理 URL 是一些默认 URL，可能是 spring 默认配置的

Error I am seeing on the console and this continues to like 60-70 attempts and counting. As you can see the broker URL that camel is picking up is some default URL that probably spring has configured by default

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

这是我当前的配置/代码:

Java 中的骆驼路线

Camel Route in JAVA

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");
    }

}

推荐答案

首先，您应该将 spring-boot-starter-activemq 依赖项添加到您的 pom.xml.然后你可以使用它的 AutoConfiguration 功能，它会根据你在 application.yml 中指定的属性创建一个 ConnectionFactory.

First you should add the spring-boot-starter-activemq dependency to your pom.xml. Then you can use its AutoConfiguration capabilities which will create a ConnectionFactory based on the properties you have specified in your application.yml.

之后，您还必须配置 Camel 的 ActiveMQComponent.如果您想重用 ConnectionFactory(由自动配置创建)，则可以通过以下方式实现:

After that you have to configure Camel's ActiveMQComponent too. If you would like to reuse the ConnectionFactory (which created by the autoconfig) then it can be achievable with the following:

@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.

You can find more information in Camel's ActiveMQ documentation.
