嵌入式AMQP Java Broker

Question

我正在尝试为连接到RabbitMQ代理的Scala/Java应用程序创建集成测试.为了达到这个目的,我想要一个能够在每次测试之前开始和停止的AMQP的嵌入式代理.最初我尝试将ActiveMQ作为嵌入式代理引入AMQP,但是应用程序使用RabbitMQ只能说AMQP版本0.9.3而ActiveMQ需要AMQP版本1.0.

我可以使用另一个嵌入式代理来代替ActiveMQ吗？

Answer 1

一个完全内存的解决方案.spring.*根据需要替换属性.

<dependency>
  <groupId>org.apache.qpid</groupId>
  <artifactId>qpid-broker</artifactId>
  <version>6.1.1</version>
  <scope>test</scope>
</dependency>

public class EmbeddedBroker {
  public void start() {
    Broker broker = new Broker();
    BrokerOptions brokerOptions = new BrokerOptions();
    brokerOptions.setConfigProperty("qpid.amqp_port", environment.getProperty("spring.rabbitmq.port"));
    brokerOptions.setConfigProperty("qpid.broker.defaultPreferenceStoreAttributes", "{\"type\": \"Noop\"}");
    brokerOptions.setConfigProperty("qpid.vhost", environment.getProperty("spring.rabbitmq.virtual-host"));
    brokerOptions.setConfigurationStoreType("Memory");
    brokerOptions.setStartupLoggedToSystemOut(false);
    broker.startup(brokerOptions);
  }
}

添加initial-config.json为资源:

{
  "name": "Embedded Test Broker",
  "modelVersion": "6.1",
  "authenticationproviders" : [{
    "name": "password",
    "type": "Plain",
    "secureOnlyMechanisms": [],
    "users": [{"name": "guest", "password": "guest", "type": "managed"}]
  }],
  "ports": [{
    "name": "AMQP",
    "port": "${qpid.amqp_port}",
    "authenticationProvider": "password",
    "protocols": [ "AMQP_0_9_1" ],
    "transports": [ "TCP" ],
    "virtualhostaliases": [{
      "name": "${qpid.vhost}",
      "type": "nameAlias"
    }]
  }],
  "virtualhostnodes" : [{
    "name": "${qpid.vhost}",
    "type": "Memory",
    "virtualHostInitialConfiguration": "{ \"type\": \"Memory\" }"
  }]
}

我已经开发了一个包装器,用于下载,提取,启动和管理RabbitMQ,因此它可以像任何JVM项目控制的嵌入式服务一样工作.

看看:https://github.com/AlejandroRivera/embedded-rabbitmq

它很简单:

EmbeddedRabbitMqConfig config = new EmbeddedRabbitMqConfig.Builder()
    .version(PredefinedVersion.V3_5_7)
    .build();
EmbeddedRabbitMq rabbitMq = new EmbeddedRabbitMq(config);
rabbitMq.start();
...
rabbitMq.stop();

适用于Linux,Mac和Windows.

以下是OrangeDog提出的适用于Qpid Broker 7.x的解决方案,灵感来自于此:

添加qpid 7.x作为测试依赖项.在7.x中,这些已经在核心+插件中分离,具体取决于您的需要.对于RabbitMQ AMQP版本,您需要qpid-broker-plugins-amqp-0-8-protocol并在内存中运行(足以进行集成测试)qpid-broker-plugins-memory-store.

pom.xml:

...
<properties>
    ...
    <qpid-broker.version>7.0.2</qpid-broker.version>
</properties>

<dependencies>
    ...
    <dependency>
        <groupId>org.apache.qpid</groupId>
        <artifactId>qpid-broker-core</artifactId>
        <version>${qpid-broker.version}</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.apache.qpid</groupId>
        <artifactId>qpid-broker-plugins-amqp-0-8-protocol</artifactId>
        <version>${qpid-broker.version}</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.apache.qpid</groupId>
        <artifactId>qpid-broker-plugins-memory-store</artifactId>
        <version>${qpid-broker.version}</version>
        <scope>test</scope>
    </dependency>
</dependecies>
...

使用硬编码的用户/密码添加代理配置,并将默认的内存虚拟主机映射到默认端口(5672):

qpid-config.json:

{
  "name": "EmbeddedBroker",
  "modelVersion": "7.0",
  "authenticationproviders": [
    {
      "name": "password",
      "type": "Plain",
      "secureOnlyMechanisms": [],
      "users": [{"name": "guest", "password": "guest", "type": "managed"}]
    }
  ],
  "ports": [
    {
      "name": "AMQP",
      "port": "${qpid.amqp_port}",
      "authenticationProvider": "password",
      "virtualhostaliases": [
        {
          "name": "defaultAlias",
          "type": "defaultAlias"
        }
      ]
    }
  ],
  "virtualhostnodes": [
    {
      "name": "default",
      "defaultVirtualHostNode": "true",
      "type": "Memory",
      "virtualHostInitialConfiguration": "{\"type\": \"Memory\" }"
    }
  ]
}

定义junit ExternalResource并声明为ClassRule(或在您的IT @BeforeClass和@AfterClass方法中启动和关闭嵌入式代理):

EmbeddedAMQPBroker.java:

public class EmbeddedAMQPBroker extends ExternalResource {

    private final SystemLauncher broker = new SystemLauncher();

    @Override
    protected void before() throws Throwable {
        startQpidBroker();
        //createExchange();
    }

    @Override
    protected void after() {
        broker.shutdown();
    }

    private void startQpidBroker() throws Exception {
        Map<String, Object> attributes = new HashMap<>();
        attributes.put("type", "Memory");
        attributes.put("initialConfigurationLocation", findResourcePath("qpid-config.json"));
        broker.startup(attributes);
    }

    private String findResourcePath(final String fileName) {
        return EmbeddedAMQPBroker.class.getClassLoader().getResource(fileName).toExternalForm();
    }
}

整合测试:

public class MessagingIT{
    @ClassRule
    public static EmbeddedAMQPBroker embeddedAMQPBroker = new EmbeddedAMQPBroker();

    ...
}
