grails - Grails的KahaDb属性

Question

通过JMS插件在Grails中使用ActiveMQ，我不知道如何设置KahaDb持久性属性。

尝试过类似的东西:

amq.broker(useJmx: true, persistent: true) {
    amq.transportConnectors() {
        amq.transportConnector(uri: "tcp://0.0.0.0:61616")
    }
    amq.persistenceAdapter() {
        amq.kahaDB(directory:${application.config.grails.moviesxd.activemq.kahadb},
                   checksumJournalFiles:true,
                   checkForCorruptJournalFiles:true,
                   ignoreMissingJournalfiles:true)          
    }
}

但是我明白了

groovy.lang.GroovyRuntimeException: Namespace prefix: kahadb is not bound to a URI

似乎无法识别kahadb前缀，但我无法在任何地方找到有关如何执行此操作的文档。

Answer 1

您只是错过了相当于

xmlns:amq='http://activemq.apache.org/schema/core'

那将是

xmlns amq:'http://activemq.apache.org/schema/core'

(有关更多信息，请参见reference docs-搜索“使用Spring命名空间”)

所以整个转换是

import org.springframework.jms.connection.SingleConnectionFactory

xmlns amq:'http://activemq.apache.org/schema/core'

amq.broker(useJmx: true, persistent: true) {
    amq.transportConnectors {
        amq.transportConnector(uri: 'tcp://0.0.0.0:61616')
    }
    amq.persistenceAdapter {
        amq.kahaDB(directory: application.config.grails.moviesxd.activemq.kahadb,
                   checksumJournalFiles: true,
                   checkForCorruptJournalFiles: true,
                   ignoreMissingJournalfiles: true)
    }
}

amq.connectionFactory(id: 'amqConnectionFactory', brokerURL: 'vm://localhost')

jmsConnectionFactory(SingleConnectionFactory, ref('amqConnectionFactory'))
