Grails 2.0.1：异步消息传递：`jmsConnectionFactory` 编译错误

Question

我有 resource.groovy

beans = {
    jmsConnectionFactory(org.apache.activemq.ActiveMQConnectionFactory) { brokerURL = 'vm://localhost' }
}

运行时显示

Message: Error creating bean with name 'delayedCreateMessageJmsListenerContainer': Cannot resolve reference to bean 'jmsConnectionFactory' while setting bean property 'connectionFactory'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'jmsConnectionFactory' is defined

升级前一切正常，更新到 2.0.1 后出现此错误失败，我使用的是 groovy 编译器 1.8.6

Answer 1

我一直在Grails中配置ActiveMQ如下：

BuildConfig.groovy

dependencies {
    compile 'org.apache.activemq:activemq-core:5.5.0'
}

resources.groovy

import org.springframework.jms.connection.SingleConnectionFactory
import org.apache.activemq.ActiveMQConnectionFactory

beans = {
    jmsConnectionFactory(SingleConnectionFactory) {
        targetConnectionFactory = { ActiveMQConnectionFactory cf ->
            brokerURL = 'vm://localhost'
        }
    }
}

Answer 2

这可能是伪装的 ClassNotFound 错误。尝试添加导入语句：

import org.apache.activemq.ActiveMQConnectionFactory

看看你是否得到了 ClassNotFoundError，如果是，那么这只是追踪丢失的依赖项的问题。
