Grails的2.0.1：异步消息：`jmsConnectionFactory`编译错误

Question

我resource.groovy

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

并运行它说

Running Grails application

它的工作都好升级之前，更新后2.0.1它失败了这个错误，我用groovy编译器1.8.6

Answer 1

这可能是伪装的ClassNotFound的错误。尝试添加一个import语句：

import org.apache.activemq.ActiveMQConnectionFactory

，看看如果你得到一个ClassNotFoundError，如果是的话那么它只是一个追踪失踪的依赖问题。

Answer 2

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' 
     } 
    } 
}
