在 Spring 注释配置中无法通过 JNDI 查找找到 JBoss ConnectionFactory

Question

尽管似乎成功绑定了 JBoss（AS 7.1.1.Final）连接工厂：

[org.jboss.as.messaging] (MSC service thread 1-9) JBAS011601: Bound messaging object to jndi name java:/ConnectionFactory

查找中的 ConnectionFactory 始终为空。谁能看出问题出在哪里？

@Configuration
@ComponentScan(basePackages = "reservation")
public class AppConfiguration extends WebMvcConfigurerAdapter {

    // ***********************//
    // ******** JMS **********//
    // ***********************//
    @Bean
    public ConnectionFactory jmsConnectionFactory() {
        JndiObjectFactoryBean jndiObjectFactoryBean = new JndiObjectFactoryBean();
        jndiObjectFactoryBean.setJndiName("java:/ConnectionFactory");
        return (ConnectionFactory) jndiObjectFactoryBean.getObject();
    }

    @Bean
    public Queue requestsQueue() {
        JndiObjectFactoryBean jndiObjectFactoryBean = new JndiObjectFactoryBean();
        jndiObjectFactoryBean.setJndiName("java:/queue/test");
        return (Queue) jndiObjectFactoryBean.getObject();
    }

    @Bean
    public JmsOperations jmsOperations() {
        final JmsTemplate jmsTemplate = new JmsTemplate(jmsConnectionFactory());
        jmsTemplate.setDefaultDestination(requestsQueue());
        return jmsTemplate;
    }
}

很遗憾，您必须手动拨打afterPropertiesSet()：

@Bean
public ConnectionFactory jmsConnectionFactory() {
    JndiObjectFactoryBean jndiObjectFactoryBean = new JndiObjectFactoryBean();
    jndiObjectFactoryBean.setJndiName("java:/ConnectionFactory");
    jndiObjectFactoryBean.afterPropertiesSet();                    //HERE
    return (ConnectionFactory) jndiObjectFactoryBean.getObject();
}

我特别喜欢的一个替代方案如下：

@Bean
public JndiObjectFactoryBean jmsConnectionFactoryFactoryBean() {
    JndiObjectFactoryBean jndiObjectFactoryBean = new JndiObjectFactoryBean();
    jndiObjectFactoryBean.setJndiName("java:/ConnectionFactory");
    return jndiObjectFactoryBean;
}

public ConnectionFactory jmsConnectionFactory() {
    return (ConnectionFactory) jmsConnectionFactoryFactoryBean().getObject();
}

注意jmsConnectionFactory() 没有用@Bean 注释（这很重要）。在这种情况下，Spring 会为您调用适当的回调方法。
