问题描述

我正在尝试在 Spring 应用程序中连接到SoftwareAg 的通用消息队列。这是我的Config课。

@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：

它在这里说：

UM 可以与 Spring 一起使用。一般来说，适用于 ActiveMQ 的 Spring XML 应该适用于 UM，只需相应更改连接工厂类和 URL。

我错过了什么？

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?

解决方案

如前所述，您引用的链接指出：

一般来说，适用于 ActiveMQ 的 Spring XML 应该适用于 UM，只需相应更改连接工厂类和 URL。[强调我的]

但是，您没有更改连接工厂类。该方法receiverActiveMQConnectionFactory正在返回一个错误的实例ActiveMQConnectionFactory。此外，该方法ActiveMQConnectionFactory.buildFromProperties()与UM 属性一起使用，这就是您获得java.io.IOException. 您不能将这两种实现混合在一起。

可能有一种方法可以简单地实例化 UM 连接工厂实现（类似于 ActiveMQ 连接工厂实现的可能），但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是获取对管理对象（即连接工厂和目标）的引用的推荐方法，这样您的 JMS 应用程序就可以在提供者之间移植。因此，我建议您简单地使用它。
