【中文标题】如何使用 Spring Boot 配置嵌入式 ActiveMQ 代理 URL【英文标题】:How to configure embedded ActiveMQ Broker URL with Spring Boot 【发布时间】:2016-12-09 14:28:27 【问题描述】:我遵循了一个使用 Spring Boot(版本 1.4.X)设置和运行嵌入式 ActiveMQ 的简单示例。这是示例的链接https://spring.io/guides/gs/messaging-jms/
我的班级结构如下:
@SpringBootApplication
@EnableJms
public class Application
@Autowired
ConfigurableApplicationContext context;
@Bean
JmsListenerContainerFactory<?> myJmsContainerFactory(ConnectionFactory connectionFactory)
SimpleJmsListenerContainerFactory factory = new SimpleJmsListenerContainerFactory();
factory.setConnectionFactory(connectionFactory);
return factory;
@JmsListener(destination = "mailbox-destination", containerFactory = "myJmsContainerFactory")
public void receiveMessage(String message)
System.out.println("Message received: " + message);
context.close();
public static void main(String[] args) throws Exception
FileSystemUtils.deleteRecursively(new File("active-data"));
ConfigurableApplicationContext context = SpringApplication.run(Application.class, args);
JmsTemplate template = context.getBean(JmsTemplate.class);
MessageCreator messageCreator = new MessageCreator()
public Message createMessage(Session session) throws JMSException
return session.createTextMessage("Test");
;
template.send("mailbox-destination", messageCreator);
和 build.gradle 如下:
apply plugin: 'java'
apply plugin: 'maven'
group = 'jms.activemq'
version = '0.0.1-SNAPSHOT'
description = """jms.activemq"""
sourceCompatibility = 1.5
targetCompatibility = 1.5
repositories
maven url "http://repo.maven.apache.org/maven2"
dependencies
compile group: 'org.springframework.boot', name: 'spring-boot-starter-activemq', version:'1.4.0.RELEASE'
testCompile(group: 'org.springframework.boot', name: 'spring-boot-starter-test', version:'1.4.0.RELEASE')
exclude(module: 'commons-logging')
到目前为止一切正常(只要我将 application.properties 留空),但如果我尝试通过将以下内容添加到 application.properties 文件来配置代理 url(以便远程客户端可以连接):
spring.activemq.broker-url=tcp://localhost:61616
spring.activemq.user=admin
spring.activemq.password=admin
我得到一个例外:

我查看了一些链接,但仍然无法确定导致问题的原因。非常感谢一些可以提供帮助的见解或材料。
我最初的想法是 Spring Boot 会读取这些值并使用它们来配置 ActiveMQ 代理,但看起来它使用这些值来连接代理(代理已经配置了不同的设置)。如何更改代理配置,以便外部客户端(不使用与代理相同的 JVM 运行)可以使用 tcp://localhost:61616 访问代理
更新:
我已按照其中一种方法嵌入列出的代理 here 并能够嵌入具有所需 URL 并能够连接到它的代理。但是,我似乎最终拥有了两个代理,因为 Spring Boot 似乎仍在继续并像以前一样创建一个。
基本上,我只是在调用 SpringApplication.run(Application.class, args); 之前添加这段代码和 main 方法的开头;
BrokerService broker = new BrokerService();
broker.addConnector("tcp://localhost:61617");
broker.setPersistent(false);
broker.start();
感觉完全不对,有两个代理实例(我相信)正在运行。
1) 这是嵌入代理的正确方法吗
2) 如果是这样,我怎样才能阻止 Spring Boot 启动另一个? (无需删除 spring-boot-starter-activemq 依赖)。
提前致谢。
【问题讨论】:
看起来 ActiveMQ 代理没有运行,或者正在侦听与您配置的端口不同的端口。请edit您的帖子并添加netstat -nat|grep LISTEN
的输出(在Windows上netstat -nat|findstr LISTEN
)
是的,我已经检查过了,没有这样的端口(之前也使用 resmon 来监视端口)。我想我的问题更像是,如何让 Spring Boot 配置代理以便它监听这个端口?我想在 application.properties 中添加该信息告诉 spring “这是我要配置代理的 url/端口”,但似乎只告诉它“这里是找到代理的位置”。我已将问题编辑得更清楚一些。
here 完整样本
【参考方案1】:
我相信我在玩了一段时间之后就明白了这一点。我认为两个实例正在运行,因为我试图创建与 DEFAULT 嵌入式代理的连接(试图确定它是否已创建/存在),如下所示:
ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory("vm://localhost?broker.persistent=false");
但显然 Spring Boot 认为一个不存在并在当时创建它。
因此,为了只运行我创建的实例,我需要做的就是在application.properties
文件中提供我在创建实例时添加到连接器的 URL(在本例中为 tcp://localhost:61616
),如下所示
spring.activemq.broker-url=tcp://localhost:61616
Spring Boot 将连接到这个实例,而不是创建另一个实例。如果属性文件中没有上述条目(或者如果您尝试使用 vm://localhost 连接到嵌入式实例?...就像我上面所做的那样),Spring Boot 将继续为您实例化一个.
我在documentation 中也读到过这篇文章:
Spring Boot 检测到的时候也可以配置一个 ConnectionFactory ActiveMQ 在类路径上可用。如果经纪人在场, 嵌入式代理会自动启动和配置(只要 没有通过配置指定代理 URL)。
但在我看来,它并没有很好地说明(但它确实让我朝着正确的方向思考)。
如果您有不同的发现或我的结论不正确,请务必告知。谢谢!!!
【讨论】:
能否请您添加其他 Spring Boot 应用程序连接到您已建立的代理所需的配置?我成功地创建了它并获得了我从创建它的应用程序发送的消息。 @MaxG 创建一个新的application-profile.yml
配置文件并放入spring.activemq.broker-url: vm://localhost?broker.persistent=false
“只要没有通过配置指定broker URL”,即不要在你的配置中提供任何spring.activemq.broker-url。然后 Spring Boot 会发挥它的魔力。以上是关于如何使用 Spring Boot 配置嵌入式 ActiveMQ 代理 URL的主要内容,如果未能解决你的问题,请参考以下文章
