php小编香蕉为您介绍Spring Boot嵌入式ActiveMQ Artemis代理连接。ActiveMQ Artemis是一款高性能、可扩展的消息代理,常用于构建可靠的消息传递系统。Spring Boot提供了简单且方便的方式来集成ActiveMQ Artemis。通过嵌入式连接,我们可以在Spring Boot应用中直接使用ActiveMQ Artemis,无需额外的配置和部署。这种连接方式不仅简化了开发过程,还提供了更高的性能和可靠性,使得消息传递更加高效和稳定。无论是开发实时应用、消息队列、还是异步通信,Spring Boot嵌入式ActiveMQ Artemis代理连接都是一个值得探索的选择。

问题内容

我有一个非常简单的 spring boot 2.7.6 activemq artemis 应用程序,用于侦听消息。

package hello;

import org.springframework.boot.springapplication;
import org.springframework.boot.autoconfigure.springbootapplication;
import org.springframework.context.annotation.bean;
import org.springframework.jms.annotation.jmslistener;
import org.springframework.jms.annotation.enablejms;
import org.springframework.jms.config.defaultjmslistenercontainerfactory;
import org.springframework.boot.autoconfigure.jms.defaultjmslistenercontainerfactoryconfigurer;
import javax.jms.connectionfactory;
import org.springframework.jms.config.jmslistenercontainerfactory;

@springbootapplication
@enablejms
public class application {

    @bean
    public jmslistenercontainerfactory<?> myfactory(connectionfactory connectionfactory,
                            defaultjmslistenercontainerfactoryconfigurer configurer) {
      defaultjmslistenercontainerfactory factory = new defaultjmslistenercontainerfactory();
      // this provides all auto-configured defaults to this factory, including the message converter
      configurer.configure(factory, connectionfactory);
      // you could still override some settings if necessary.
      return factory;
    }

    public static void main(string[] args) {
       springapplication.run(application.class, args);
    }

    @jmslistener(destination = "my-queue-1")
    public void listen(string in) {
       system.out.println(in);
    }
}

这是配置嵌入式代理的代码。我只是通过添加多个接受器来猜测。不同的帖子引用了 addconnectorconfiguration,但到目前为止它们似乎都不起作用。

package hello;

import org.apache.activemq.artemis.api.core.transportconfiguration;
import org.apache.activemq.artemis.core.remoting.impl.netty.nettyacceptorfactory;
import org.apache.activemq.artemis.core.remoting.impl.netty.nettyconnectorfactory;
import org.springframework.boot.autoconfigure.jms.artemis.artemisconfigurationcustomizer;
import org.springframework.context.annotation.configuration;


@configuration
public class artemisconfig implements artemisconfigurationcustomizer {
    @override
    public void customize(org.apache.activemq.artemis.core.config.configuration configuration) {
      configuration.addacceptorconfiguration("remote", "tcp://0.0.0.0:61616");
    }
}

通过这个简单的 application.properties

spring.artemis.mode=embedded
spring.artemis.embedded.server-id=54321
spring.artemis.embedded.queues=my-queue-1
spring.artemis.embedded.enabled=true

然后我有另一个 spring boot 应用程序,它生成消息并将它们发送到代理地址。

package broker.producer;

import org.apache.activemq.artemis.jms.client.activemqconnectionfactory;
import org.slf4j.logger;
import org.slf4j.loggerfactory;
import org.springframework.beans.factory.annotation.value;
import org.springframework.context.annotation.bean;
import org.springframework.jms.core.jmstemplate;
import org.springframework.jms.support.destination.jndidestinationresolver;
import org.springframework.stereotype.service;

@service
public class jmsproducer {

  @value("${spring.jms.template.default-destination}")
  private string defaultdestination;

  logger log = loggerfactory.getlogger(jmsproducer.class);

  @bean
  public activemqconnectionfactory activemqconnectionfactory() {
      activemqconnectionfactory activemqconnectionfactory = new activemqconnectionfactory("tcp://localhost:61616");

      return activemqconnectionfactory;
  }

  @bean
  public jndidestinationresolver jndidestinationresolver() {
    return new jndidestinationresolver();
  }

  @bean
  public jmstemplate jmstemplate() {
    jmstemplate template = new jmstemplate();
    template.setconnectionfactory(activemqconnectionfactory());
    template.setpubsubdomain(false); // false for a queue, true for a topic
    template.setdefaultdestinationname(defaultdestination);

    return template;
  }


  public void send(string message) {
    jmstemplate jmstemplate = jmstemplate();

    log.info("sending message='{}'", message);
    jmstemplate.convertandsend(message);
    log.info("sent message='{}'", message);
  }
}

然后我启动每个应用程序并尝试调用发送方法,但由于此错误,我无法从生产者应用程序连接到代理:

2024-01-16 10:25:00.596 ERROR 30486 --- [nio-8080-exec-1] o.a.c.c.C.[.[.[/].[dispatcherServlet]    : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.jms.UncategorizedJmsException: Uncategorized exception occurred during JMS processing; nested exception is javax.jms.JMSException: Failed to create session factory; nested exception is ActiveMQNotConnectedException[errorType=NOT_CONNECTED message=AMQ219007: Cannot connect to server(s). Tried with all available servers.]] with root cause

生产者应用程序能够很好地连接到 activemq artemis 的 docker 实例。

目前,两个应用程序都在同一台计算机上运行,​​但在产品中,我希望每个应用程序在单独的 pod 中运行。

解决方法

我整理了一个非常简单的项目作为概念验证,以确保您正在做的事情是可能的,并且一切对我来说都运行良好。嵌入式代理已启动并在端口 61616 上接受来自远程客户端的连接。

这是 application.java

package hello;

import javax.jms.connectionfactory;
import org.springframework.boot.springapplication;
import org.springframework.boot.autoconfigure.springbootapplication;
import org.springframework.boot.autoconfigure.jms.defaultjmslistenercontainerfactoryconfigurer;
import org.springframework.context.annotation.bean;
import org.springframework.jms.annotation.enablejms;
import org.springframework.jms.annotation.jmslistener;
import org.springframework.jms.config.defaultjmslistenercontainerfactory;
import org.springframework.jms.config.jmslistenercontainerfactory;

@springbootapplication
@enablejms
public class application {

    @bean
    public jmslistenercontainerfactory<?> myfactory(connectionfactory connectionfactory,
                                                                    defaultjmslistenercontainerfactoryconfigurer configurer) {
        defaultjmslistenercontainerfactory factory = new defaultjmslistenercontainerfactory();
        // this provides all auto-configured defaults to this factory, including the message converter
        configurer.configure(factory, connectionfactory);
        // you could still override some settings if necessary.
        return factory;
    }

    public static void main(string[] args) {
        springapplication.run(application.class, args);
    }

    @jmslistener(destination = "my-queue-1")
    public void listen(string in) {
        system.out.println(in);
    }
}

这是 artemisconfig.java

package hello;

import org.springframework.boot.autoconfigure.jms.artemis.artemisconfigurationcustomizer;
import org.springframework.context.annotation.configuration;


@configuration
public class artemisconfig implements artemisconfigurationcustomizer {
    @override
    public void customize(org.apache.activemq.artemis.core.config.configuration configuration) {
       try {
          configuration.addacceptorconfiguration("remote", "tcp://0.0.0.0:61616");
       } catch (exception e) {
          e.printstacktrace();
       }
    }
}

这是我的 application.properties

spring.artemis.mode=embedded
spring.artemis.embedded.server-id=54321
spring.artemis.embedded.queues=my-queue-1
spring.artemis.embedded.enabled=true

最后,这是我的 pom.xml

<?xml version="1.0" encoding="utf-8"?>
<project xmlns="http://maven.apache.org/pom/4.0.0" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"

        <version>${spring.version}</version>
         </plugin>
      </plugins>
   </build>
</project>

我像这样启动应用程序:

mvn spring-boot:run

我看到这样的日志记录:

...
... AMQ221020: Started EPOLL Acceptor at 0.0.0.0:61616 for protocols [CORE]
... AMQ221007: Server is now live
...

我可以从另一个应用程序向代理发送消息,并且 jmslistener 会接收该消息。

我已将项目上传到 github
