错误:预期的类或对象定义 [英] error: expected class or object definition

问题描述

我有这个(智能代码):

I have this (smart code):

import com.mongodb.casbah.Imports._
import com.mongodb.casbah.util.bson.conversions._
RegisterJodaTimeConversionHelpers() //error

object Main {
  def main(args: Array[String]) {
    val connection = MongoConnection()
  }
}

我得到一个错误:

error: expected class or object definition
RegisterJodaTimeConversionHelpers()

我必须使用此 RegisterJodaTimeConversionHelpers() (2.2. :自动类型转换)，但始终会出现此错误消息.有什么想法吗?

I have to use this RegisterJodaTimeConversionHelpers() (2.2. Briefly: Automatic Type Conversions), but there's always this error message. Any ideas?

推荐答案

您必须在可执行代码的地方编写此行代码.相反，在您的main方法中呢?

You have to write this line of code somewhere it can be executed. How about in your main method instead?

object Main {
  def main(args: Array[String]) {
    RegisterJodaTimeConversionHelpers()
    val connection = MongoConnection()
  }
}
