无法识别运输方案：[nsp]

Question

我正在尝试连接到Spring应用程序中的SoftwareAg的通用消息传递队列。这是我的Config类。

@Configuration
@EnableJms
public class Config {

    @Bean
    public ActiveMQConnectionFactory receiverActiveMQConnectionFactory() {
        ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory();

        var properties = new Properties();
        properties.setProperty(Context.INITIAL_CONTEXT_FACTORY, "com.pcbsys.nirvana.nSpace.NirvanaContextFactory");
        properties.setProperty(Context.PROVIDER_URL, "nsp://localhost:9200");
        activeMQConnectionFactory.buildFromProperties(properties);

        return activeMQConnectionFactory;
    }

    @Bean
    public DefaultJmsListenerContainerFactory jmsListenerContainerFactory() {
        var factory = new DefaultJmsListenerContainerFactory();
        factory.setConnectionFactory(receiverActiveMQConnectionFactory());
        factory.setConcurrency("3-10");
        return factory;
    }

} 

这是我的pom.xml的一部分

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-activemq</artifactId>
</dependency>
<dependency>
    <groupId>org.apache.activemq</groupId>
    <artifactId>activemq-broker</artifactId>
</dependency>
<dependency>
    <groupId>com.pcbsys.nirvana</groupId>
    <artifactId>nClient</artifactId>
    <version>1.0</version>
</dependency>
<dependency>
    <groupId>com.pcbsys.nirvana</groupId>
    <artifactId>nJMS</artifactId>
    <version>1.0</version>
</dependency>

但是，当我尝试连接到队列时，出现以下异常：

它说here：

UM可以与Spring一起使用。通常，适用于ActiveMQ的Spring XML应该适用于UM，而只需更改连接工厂类和URL。

我想念什么？

编辑：

var properties = new Properties();
properties.setProperty(Context.INITIAL_CONTEXT_FACTORY, "com.pcbsys.nirvana.nSpace.NirvanaContextFactory");
properties.setProperty(Context.PROVIDER_URL, "nsp://localhost:9200");

Context ctx = new InitialContext(properties);
return (ConnectionFactory) ctx.lookup("local_um"); // THIS?

Answer 1

如前所述，您引用的链接指出：

通常，适用于ActiveMQ的Spring XML应该仅使用连接工厂类即可用于UM，并且相应地更改了URL。 [强调我的]

但是，您还没有更改了连接工厂类。方法receiverActiveMQConnectionFactory返回错误的ActiveMQConnectionFactory实例。此外，该方法使用ActiveMQConnectionFactory.buildFromProperties()和UM properties，这就是为什么要获取java.io.IOException的原因。您不能将这两种实现混合在一起。

[也许有一种方法可以简单地实例化UM连接工厂实现（类似于ActiveMQ连接工厂实现可能的方法，但是我认为您可能必须查阅UM开发人员指南以获取该信息。

也就是说，JNDI 是获得对管理对象（即连接工厂和目标）的引用的推荐方法，以便您的JMS应用程序可在提供程序之间移植。因此，我建议您只使用它。

Answer 2

我终于设法解决了。这对我有用：

@Configuration
@EnableJms
public class Config {

    @Bean
    public DefaultJmsListenerContainerFactory jmsListenerContainerFactory() {
        var factory = new DefaultJmsListenerContainerFactory();
        factory.setConnectionFactory(cachingConnectionFactory());
        factory.setConcurrency("3-10");
        return factory;
    }

    @Bean
    @Primary
    public CachingConnectionFactory cachingConnectionFactory() {
        final CachingConnectionFactory cachingConnectionFactory = new CachingConnectionFactory();
        cachingConnectionFactory.setSessionCacheSize(200);
        cachingConnectionFactory.setTargetConnectionFactory((ConnectionFactory) jndiObjectFactoryBean().getObject());

        return cachingConnectionFactory;
    }

    @Bean
    public JndiTemplate jndiTemplate() {
        final Properties properties = new Properties();
        properties.setProperty(Context.INITIAL_CONTEXT_FACTORY, "com.pcbsys.nirvana.nSpace.NirvanaContextFactory");
        properties.setProperty(Context.PROVIDER_URL, "nsp://local-dev:9200");

        final JndiTemplate jndiTemplate = new JndiTemplate();
        jndiTemplate.setEnvironment(properties);

        return jndiTemplate;
    }

    @Bean
    public JndiObjectFactoryBean jndiObjectFactoryBean() {
        final JndiObjectFactoryBean jndiObjectFactoryBean = new JndiObjectFactoryBean();
        jndiObjectFactoryBean.setJndiTemplate(jndiTemplate());
        jndiObjectFactoryBean.setJndiName("jndi_key");
        return jndiObjectFactoryBean;
    }

}

我希望它可以帮助某人。不要忘记将nClient.jar和nJMS.jar添加到您的类路径中。您可以在UM安装lib目录中找到它们。
