我在使用MongoDB配置创建GenericGroovyApplicationContext时遇到了麻烦 . groovy配置如下：

package groovy
import com.mongodb.Mongo
import org.springframework.core.io.ClassPathResource
import org.springframework.data.mongodb.core.MongoTemplate

beans {
    xmlns([ctx:'http://www.springframework.org/schema/context'])
    xmlns([mongoNamespace:'http://www.springframework.org/schema/data/mongo'])

    def config = new ConfigSlurper().parse(new ClassPathResource('groovy/mongodbconfig.groovy').URL)
    mongo Mongo
    mongoTemplate(MongoTemplate, mongo, config.mongo.dbname)
    mongoNamespace.'repositories'('base-package':'mypackage.data.dao')
}

我得到以下错误（无论是否创建了mongoTemplate bean）：

调试后，我发现在使用xml spring配置时调用时没有调用MongoRepositoryFactoryBean＃setMongoOperations . 有没有人有想法如何解决它？谢谢 .
